TOPIC: The Tao of It and Bit by Cristinel Stoica [refresh]

TOPIC: The Tao of It and Bit by Cristinel Stoica [refresh]

The main mystery of quantum mechanics is contained in Wheeler's delayed choice experiment, which shows that the past is determined by our choice of what quantum property to observe. This gives the observer a participatory role in deciding the past history of the universe. Wheeler extended this participatory role to the emergence of the physical laws (law without law). Since what we know about the universe comes in yes/no answers to our interrogations, this led him to the idea of it from bit (which includes the participatory role of the observer as a key component). The yes/no answers to our observations (bit) should always be compatible with the existence of at least a possible reality – a global solution (it) of the Schrodinger equation. I argue that there is in fact an interplay between it and bit. The requirement of global consistency leads to apparently acausal and nonlocal behavior, explaining the weirdness of quantum phenomena. As an interpretation of Wheeler's it from bit and law without law, I discuss the possibility that the universe is mathematical, and that there is a "mother of all possible worlds" - named the Zero Axiom.

Cristi Stoica is a PhD student, specialized in differential geometry and mathematical physics. A draft of his PhD thesis, which is about singularities in general relativity, can be downloaded at http://arxiv.org/abs/1301.2231

Cristi,

What a truly excellent essay! I will be very surprised and disappointed if you are not a winner. I may later argue a point or two but I simply want to congratulate you on a job well done.

With respect to Smolin's treatment of laws versus Wheeler's treatment, I think Smolin says it best that "If everything that is real is real in a moment, then the distinction between laws and states must be a relative one."

You've stated, "If one believes that there are things that are not included in the mathematical model of the universe, one should describe these things." That is sort of a 'trick question'. If something can be described in words, one can make a mathematical model of some sort. I agree with Smolin that "There are aspects of the real universe that will never be representable in mathematics."

Your Yin-Yang diagram is probably the best way the it/bit question can be answered!

A job well done.

Best,

Edwin Eugene Klingman

So energy tries radiating out to infinity, before flatlining to black, while structure tries collapsing to a point, but reaching a parabolic boil that shoots it out across the cosmos.

Is zero the point, or the flatline? Or both?

Dear Tom,

Thanks for reading my essay, and for the kind comments. You raise two points. I don't think that your comment to the first point contradicts what I said. You say "If infinity is a physical condition, then well behaved solutions -- representing physical conditions -- drive the phenomena, and not the other way around", I agree, and "the other way around" is not my position, although you make it sound like it is. My position is the "global consistency principle". As for the second point, you write between quotes "Zero is an axiom.", which is supposed to be quoted from my essay, but it is not. Also, you say that I call liar's paradox logically consistent, which I don't.

Best regards,

Cristi

I hope my reply to John Merryman's comment above yours may clarify what I meant by the Zero Axiom, and its relation with logical consistency: "Axiom Zero gives birth to each possible universe (because of the principle of explosion [...]), but it is not part of any of these universes, because this would contradict logical consistency."

It is not about belief, dear Edwin Eugene. The information is real in the sense that there is outside the observer, even if not Perform observation.Information is, for example, number of particles. The universe is in itself, full of information, for the simple reason, that everything can be measured, counted, etc. are numbers, and the numbers are pure information.Therefore,So, for example, the Bekenstein bound is an upper limit on the entropy S, or information I, That can be contained Within a Given finite region of space Which has a finite amount of energy.

The vacuum energy density is a pure numerical value, and independent, its value, the observation process, since the expansion of the universe itself, is conditioned to this numerical value.

I do not believe, observe, make theories to explain the observed phenomena, using an informational process of creating algorithms (equations) that give some outputs, and it then taste numerical information outputs of these equations, or algorithms, with the reality of the phenomenon observed physical, measured.All this is information, not subjective beliefs.If I make a theory, with which using an algorithm or routine (equations, etc.), get the measured value of pure number density of vacuum (0.6931 ...), that is objective and real, and it is information. Everything else is to juggle metalinguistic, which are fine for philologists, but does not help the physicists.

Yes, I totally agree that, that part of reality, or what we call reality as mental model, corresponding to algorithmic processes.As you well know, there are numbers, not algorithmically constructibles. You aims high: There is some physical phenomenon (unknown for now) that can not be computed algorithmically?, And therefore we can not speak of it in terms of what is known by orthodox science, and information. That's a great question. Maybe if there are physical "facts" that are not computable. And therefore speak of these "realities" in terms of information does not make sense, to be unplayable for any algorithm. This is another question, very different

I agree that "It from Bit" can't be determined by a quantum binary, or n-ary, algorithmic or axiomatic system. Wheeler talked in these regard to the "choice" we have in determining the configuration of physics or physical law as a participatory universe. He then said that one is unable to frame the laws of physics in a complete axiomatic framework because the acto of observation is self-reference.

My essay hits on this part, where I think "It from Bit" is not formally decidable. I think this is a good thing, for it means there is a new layer of physical principles waiting to be discovered --- or to think in the Wheeler sense maybe "chosen."

Cheers LC

Good essay! I didn't understand it all, but the last part about Axiom Zero and the creation of any possible universe via the principals of explosion and logical consistency resonated with me. Starting with a single state (Axiom Zero), one can create an infinite space of other states (other possible universes). If each individual state could be considered to be a location in a larger set of states, then an expanding space has been created. Kind of sounds like the Big Bang! I'm going to be writing something along this line in my essay, too.

Anyways, nice essay!

The issue is very simple. Observation can have no effect on the physical circumstance, as that has already occurred. Furthermore, the physical interaction of observation which is the receipt of physical input (what happens subsequently being irrelevant because it is not physics) involves a physically existent representation of what occurred anyway. It is commonly known as light.

Once that is understood, then all the 'wierdness' can be seen for what it is, ie attempts to rationalise an incorrect base premise as to how physical existence occurs.

Thank you for the explanations. I am glad you got over the 'weirdness', with this very simple classical picture. For me quantum mechanics is still full of mysteries, and the only way they could make more sense to me was to think them in terms of delayed initial conditions and global consistency.

Cristi, A well presented and logically thought out essay, unfortunately your figure 8 does not display properly in chrome or firefox (I have not tried IE) but once downloaded Adobe renders Fig 8 correctly. Maybe you should try and fix that and ask FQXi organizers to replace the file.

I concur fully with you, especially the paragraph "The Big Book of the Universe" and your statement that the universe is isomorphic to a mathematical structure. I takes quite some abstract and brave thinking to accept that conclusion; especially the implications that one thoughts , dreams, acquired knowledge, etc are just mathematics at work.

Next, I will read your PH.D. thesis and hoping to find equally brave statements.

Dear Philip,

You are right in asking "You suggest that to be able to choose from different laws the universe needs to evolve. Why can't they just be chosen from the set of logical possibilities? Why the need to connect them in s temporal progression?"

My essay is centered on Wheeler, but I wanted also to bring something new. Wheeler advocated this kind of evolution of laws. Smolin, with his Cosmological natural selection, offered a solution, but to go to baby universes, you have to go through singularities (or at least to "bounce" them, as in LQC). So, this was an opportunity to offer another application of my approach to singularities. This was in the section "Evolving Laws", but later, in "From Chaos to Law", I say "any possible world appears, due to the principle of logical consistency". Hence, I don't actually think this needs evolving laws.

Now, back to your question "Why can't they just be chosen from the set of logical possibilities?".

I agree with you, they are just chosen from the set of logical possibilities, but this doesn't mean the choice can't evolve.

Thank you for the kind comment, and I can't wait to read your essay.

Best regards,

Cristi

Thank you for that. I think you are wisely keeping your options open. Of course Smolin argues the case that evolution of physics is a necessity to get where we are. With evolution of life we can see roughly how a progression can start from very simple chemical life forms to the more complex animals and plants we are familiar with. If cosmic evolution requires baby universes from the beginning then the starting point is already very complex and selective. Simple universes would not have babies so how did things get going? This would be more a question for Wheeler or Smolin I suppose.

report post as inappropriate

I fully agree. In fact, looking at what we know so far in fundamental physics, I don't see too much room for evolution of the laws. At most some constants that are reset at the next big bang, but how many constants really are obtained from symmetry breaking, and can be expected to be actually variable? Of course, if we want to save the idea of evolving laws, we can appeal to the string landscape, and imagine that, when passing in the baby universe, the Calabi-Yau manifold can change. But I don't know if this can go anywhere.

Hi Cristi,

Nice essay, easy enough to read that even I can understand it (I am not a physicist).

I agree with your global consistency principle, I have an example of how it could be implemented.

In my essay (Definetely It from Bit !) the Universe is a succession of 2D layers of information (like rings around an onion). We (and our surrounding world) are just information moving up the layers at the speed of light. In relation to each layer, the inner layers represent the past and the outer layers represent the future. Each layer can evolve separately but they must always form a "coherent" storyline. (there are as many "presents" as there are layers).

If I am correct, then the consecutive layers (ie: the complete information sphere) could be what you call "the solution (it) which combines consistently all the pieces of the puzzle (the yes/no bits at different points and moments of time)"

Cheers,

Patrick

I must take exception to your statement that "The main mystery of quantum mechanics is contained in Wheeler's delayed choice experiment."

Last September, in the discussion of my essay for the previous FQXI essay contest, I pointed out that the delayed choice experiment, was not merely badly designed, but badly conceived. The telescopes block the path from a slit just as surely as if the slit had been closed. It thereby precludes any possibility for this apparatus to produce an "interference pattern".

It is not the case that "the past is determined by our choice", rather it is "the path is determined by our choice".

Consequently, Wheeler threw the baby out with the bath water.

Dear Robert,

I think you have a keen eye for telescopes and optics. Delayed choice experiments, not at galactic scale, but at lab scale, were performed, and the delay was ensured. The experiment confirmed the theoretical prediction.

Wheeler proposes the delayed choice experiment with the Mach-Zehnder interferometer, and also the one with a telescope and galaxy. I think that the one with telescope and galaxy is an exaggeration, done for explanatory reason. Something like Brian Greene's Quantum Cafe, or Gamow's books with Mr. Tompkins, where quantum or relativistic phenomena are "zoomed" at a level which makes them relevant to our daily experience. Or like Bohr's quantum devices, with exaggerated mechanical parts.

I am not sure that Wheeler really tried to design a workable experiment involving telescope and light from other galaxies. One big issue I think it is the lack of control of the source of light. By looking at Wheeler's drawing of the experimental setup, in Quantum Theory and Measurement, p. 139, we see that the device is more like Bohr's drawings of devices. But even so, I don't see in that picture how the telescope would block the path from a slit. Perhaps you analyzed a different picture than the one I found.

Thanks for the comment, and keep questioning everything! When we stop questioning, science stops.

I think you have a keen eye for telescopes and optics. Delayed choice experiments, not at galactic scale, but at lab scale, were performed, and the delay was ensured. The experiment confirmed the theoretical prediction.

Wheeler proposes the delayed choice experiment with the Mach-Zehnder interferometer, and also the one with a telescope and galaxy. I think that the one with telescope and galaxy is an exaggeration, done for explanatory reason. Something like Brian Greene's Quantum Cafe, or Gamow's books with Mr. Tompkins, where quantum or relativistic phenomena are "zoomed" at a level which makes them relevant to our daily experience. Or like Bohr's quantum devices, with exaggerated mechanical parts.

I am not sure that Wheeler really tried to design a workable experiment involving telescope and light from other galaxies. One big issue I think it is the lack of control of the source of light. By looking at Wheeler's drawing of the experimental setup, in Quantum Theory and Measurement, p. 139, we see that the device is more like Bohr's drawings of devices. But even so, I don't see in that picture how the telescope would block the path from a slit. Perhaps you analyzed a different picture than the one I found.

Christi,

The statement "The experiment confirmed the theoretical prediction." is incorrect.

The experiment confirmed that the interference pattern vanishes. But it failed to confirm that the cause for the vanishing is due to the cause that was predicted. It was not.

The situation is analogous to preventing two cars from interfering (colliding) with each other at an intersection. Delaying one car will prevent the collision, but so will completely eliminating one car.

In effect, the experiment simply eliminates one travel path, via a spatial filter. The delayed choice is irrelevant - if there is no path, there can never be any interference, regardless of any delayed choice.

The telescope I was referring to is not an astronomical one. It is part of the laboratory interferometer, and used to "choose" the slit.

Hi Eckhard,

thanks for the link, the paper is interesting for me too.

I read it and i think it is yet too technical for the average reader to understand. At least i didn't understand what is the "true" reason for the interference pattern to disappear in the case the screen is moved out of the experimental setup (Appendix A: Wheeler's thoughts).

Can anybody explain it to me in more intuitive words, with destructive and constructive interference instead of conditional probabilities and all that stuff. Means, that stuff is highly abstract but i want to know how one can put it in terms of physical processes (be it with or without time ordering).

Thanks in advance,

Stefan

Stefan,

I am sorry, I didn't deal with the matter. My intention was to hopefully clarify whether Wheelers mysterious claims can be explained at all without the rather disappointing result that they are based on mistakes or at best on beliefs.

I was tempted to blame Wheeler for phantasmagoria unless he was not well known for his earlier contributions to nuclear fission and atomic bombs. Of course, the strange theories he got then famous for go back to earlier speculative work e.g. by Parmenides, Einstein, Schwarzschild, Bohr, Rosen, and others.

Dear Christi,

your essay was an interesting read. I think your realization that ultimately, all we know of the world are relations is very deep, and is in a certain sense at the foundation of my own thinking, as well. However, I am less certain about the 'book containing every truth': this seems to me to run into trouble with the Kochen-Specker theorem (and related ones). In particular, if such a book existed, it would imply the existence of a global probability distribution such that its marginals give the outcomes for every possible set of observations; but this is known to be at variance with quantum mechanics. Put differently, while classically we can identify every object with a list of properties, of propositions true about this object, in quantum mechanics, no such list can exist. Any theory for which such a list exists necessarily obeys Bell's inequalities (and Kochen-Specker and Leggett-Garg inequalities, which are from this point of view just variations on a theme). (I think this connection was probably first worked out by Fine.)

Nevertheless, your big book seems to be very much a 'hot idea' in philosophy at the moment, after having been somewhat maligned after the 'noble failure' of Carnap's "Der Logische Aufbau der Welt"; three books have appeared in the past year dealing in various ways with the possibility of deriving all truths about the universe from some 'compact class' of basic truths: David Chalmers' "Constructing the World" (which is the only one I've read... well, I should say 'almost read'), Theodore Siders' "Writing the Book of the World", and John Heil's "The Universe as we Find It", so you're certainly at the bleeding edge in that respect! (Just in case you're interested.)

In any case, as a fellow PhD student in physics, I wanted to emphasize one point you made, though only somewhat implicitly, and only tangentially related to the main thrust of your essay: that of the necessity for courage in the scientific endeavour. Building on the Kuhnian model of scientific revolution, one might say that the ordinary, stick-to-the-mainstream method of science fails to produce the most important new ideas: it only clusters around local maxima, so to speak. For true innovation, one must sometimes leap beyond what seems reasonable, or even sensible within the current paradigm. Of course, many, if not most, such leaps will lead to nothing, which is why one needs courage to make them---a courage which John Wheeler certainly possessed, as you have shown in your essay.

Dear Jochen,

It's a pleasure to read such deep and well thought comments. Thank you for the attention given to my essay. I look forward to reading yours asap.

You said "I am less certain about the 'book containing every truth': this seems to me to run into trouble with the Kochen-Specker theorem (and related ones)." Any theorem has a domain of applicability. The Kochen-Specker and co. theorems are a great toolbox, with which I fully agree, and which rule out a certain class of attempts to describe reality. It would rule out the book containing every truth, if you would want it for instance to contain information about what the spin is along each direction, which will give definite results no matter how we will choose three orthogonal directions along which we measure the squared components of the spin. But I make no such claim. If one of the truths is what the squared components are, this should be accompanied by the three directions along which we measure. "Put differently, while classically we can identify every object with a list of properties, of propositions true about this object, in quantum mechanics, no such list can exist." I agree, but it makes no sense to have such a list in the book. I don't claim that the book will contain both position and momentum of a particle. This makes sense only classically. If you want it to contain both, you will run into the trouble you mention, but there is no need to do this. Why asking the state vector to be simultaneously eigenstate of incompatible observables? It is like asking the insect to be both a fly and a dragonfly, at the same time. To refer to the delayed choice experiment of Wheeler, if you want the book to contain information whether which-way or both-ways, it also has to contain information about whether the second beam splitter will be in place or not. The book should contain proposition about elements of reality, only together with the context. I tried to capture and explain this using the concepts of "delayed initial conditions" and "global consistency principle". Conditions at various points in spacetime should be mutually consistent, even if they are one in the future of the other, even if they are separated and can't exchange information without violating the speed of light.

Thank you for the references you gave, I am interested in principle. With "the book", I just wanted to make the point of how mathematical our universe can be. I am not sure I want to develop more this idea, but no matter if I will or not, I am sure the references you gave me will be very useful.

Best regards,

"while classically we can identify every object with a list of properties"

But we cannot. There is no object, physically. That is a conception at a much higher level than how reality occurs, based on certain superficial physical attributes. Which is why the classical/intuitive view has been denigrated, because it has not been followed through to its proper logical...

Christi, yes, I think I missed the importance of your 'global consistency principle'. Indeed, if you intend for the big book to contain truths that include their proper (measurement) context, then you avoid the difficulties with Kochen-Specker etc.

I think I see two ways how this might work: one is a kind of 'superdeterminism', where what measurements are performed is fixed for any given instance; the other amounts to the book containing truths that are conditional on the performed measurements. It seems to me that you advocate the former strategy: the world is, in a sense, given by an action principle; it is like the famous catenary problem, wholly determined by initial and final conditions. The latter strategy is essentially what I've argued for: the book only contains relative facts, of the form 'if such-and-such a measurement is performed, the outcome is this-and-that', which then sort of co-exist peacefully. So maybe our perspectives are not that far from one another!

Also, somewhat amusingly, both solutions have a distinctly Leibnizian character: yours pertaining to his notion of the 'best of all possible worlds', while mine relates to his overall relational philosophy.

Paul, in a classical world, you can certainly always draw up a list of properties, and then clarify by that what you mean when you talk about 'an object'. What happens at the foundational level doesn't really have a bearing on this.

Dear Jacek,

Thank you for the careful reading and the comments. I find interesting the way you see the first axiom of the universe. Later, you ask "The geometry is a part of mathematics and is completely about relations. But does the spacetime need a mathematics to exist?" I am not sure how they can be separated, so that spacetime can exist without math. I don't understand what you mean. Say math was never discovered, and somehow all humans would have evolved, as people who know to survive, develop various crafts, and maybe arts, but no math at all. I find very possible, and if there is such a civilization in the universe, I think one should not consider them inferior, just because of that. But, I don't think they can do without math, in the sense that math is implicit anywhere. A spacetime without math, I can't picture. Our spacetime doesn't seem to be without math. Perhaps the subsequent comment you make, about the failure of geometrodynamics, explains what you meant. Maybe the final word is not yet said. Some things they tried worked, but not all, who knows what will be. About the book of true propositions, it will contain every true, including the ones you refer to as not computable or not deterministic. I don't claim that the book is a finite set of axioms, and the consequences that can be proven by finite length proofs. It contains everything. I hope figure 8 in my essay clarifies this. Good observation, it gave me the opportunity to explain better!

Best regards,

Cristi

Dear Cristi,

You refer to "...does the spacetime need a mathematics to exist?" I am not sure how they can be separated, so that spacetime can exist without math…

I will try to explain: the spacetime can be defined only as a mathematical entity created by observers (Platonic) but it is not necessary. It can be defined as a purely physical entity (real) that does not need observers. As you see the approach to spacetime can be dual: one mathematical and one physical (Einstein also attributed an elasticity property to the spacetime regarding it as physically existing entity but not the ether). I don’t know if my view is clear. It is a lot of language intricacies and philosophy involved in the issue. It is very hard and maybe impossible to stay independent from our language and culture notions.

Jacek,

If I may offer up a point about time, ask yourself the question of whether it makes more sense to say the earth exists along a fourth dimension, from yesterday to tomorrow, or that tomorrow becomes yesterday because the earth rotates?

As I see it, the problem is that we experience time as a sequence of events, much as we still see the sun moving across the sky, from east to west, yet like the underlaying reality of the earth spinning west to east, it is the events moving through the physical actuality of what is present, as it is constantly changing, not the present moving along some extra-dimensional vector.

Because physics treats time as only a measure of duration, it re-enforces this sequential perception, rather than revealing its cause. Duration is not an external vector to the point of the present, but is the state of the present between events.

As effect of action, time would be similar to temperature, much as frequency and amplitude are features of waves.

So spacetime as causal, is no more real than giant cosmic gearwheels spinning in the heavens, as explanation for the mathematical effectiveness of epicycles.

Dear Cristinel

I enjoyed going through your engaging essay - every topic you chose was interesting, pertinent, beautifully explained and illustrated and thought-provoking. As a mathematician you should know how fertile and precocious the field is - so many different ways to express the same situation. Combine that with the cleverness and imagination of a Feynman or a Wheeler and you get truly mind-boggling choices in how to represent the Universe. Unfortunately It=It and one feels that the simpler a model is the more probably it is right - a single universe vs. many - one history instead of multiple ones etc, local causality vs. probability.

The delayed-choice beam-splitter experiment is brilliant. Sadly it has been now made meaningless after Eric Reiter's experiments, backed by solid theoretical and historical analysis of the issues involved, with beam-splitters showing that light-quanta do not 'choose' one path or another, but as waves (not point photons) are detected by both detectors simultaneously. Reiter reported about this in his 2012 fqxi essay and on his website unquantum.net . How such an important experimental challenge demolishing the inherent probability in Nature (the Born Rule) can be so neglected by the physics community is beyond me.

With best wishes, Vladimir

Dear Vladimir,

Thank you for your kind comments. There are some points which I probably should have made clearer. For instance, when I speak about delayed initial conditions and global consistency, I don't need to advocate MWI, although I don't reject it either. About Wheeler's delayed-choice beam-splitter experiment, I happen to know that it was confirmed by experiments. I agree that photons are waves: in QM they are, in the first place, solutions to Schrodinger's equation. When you measure positions, they become for an instant very localized, but still they are waves. I hope this eliminates some confusions. I didn't have the chance to read your essay yet.

Cristi

Dear Cristi

If I along with many debunkers of QM weirdness are right, Wheeler's delayed choice test being confirmed by experiment does not mean much. Here is a quick-and dirty explanation of how I see the scenario:

Forget point photons, wave collapse and all that. Einstein's 'photon' concept is the font of all the QM weirdness he himself railed against! Compton himself gave a wave explanation for his effect as Reiter explained on unquantum.net - all proving Planck's loading theory in which an atom releases light suddenly but absorbs it slowly until a threshold is reached and the (hv) quantum released.

In other words the light wave passes simultaneously through both slits and creates the wave interference pattern beyond them. In the famous faint-light case when the pattern emerges dot by dot on the long-exposed film the timing of the dot flashes in the film is an artifact of the sensing atoms individually and randomly reaching their energy threshold and has nothing to do with how the light went through the slits!

When the film is removed and two telescopes watch the slits no simultaneous sensing is recorded because of the energies involved. Reiter has shown how a single gamma ray is simultaneously recorded in two detectors.

I have touched on these issues in my 'Fix Physics' paper, and the scenario above plays out nicely in the universal node lattice of my Beautiful Universe theory.

These papers can be read on my website . I am now trying to simulate my theory to show how things like matter formation, gravity, quantum probability etc. all emerge locally linearly and causally. Big job small capability!

This explanation might be correct, but the danger is that there is then an argument over alternatives.

Whereas in fact:

-QM is an invalid theory because its base presumptions are contrary to the way in which physical existence must occur

-there is no way in which any form of experimentation can identify the 'bottom line', the degree of alteration and duration involved is too vanishingly small of itself, let alone that, in terms of observation, we receive a representation of it. So the effect known as light would have to be capable of capturing and transmitting accurately and comprehensively exactly what occurred. We are kidding ourselves. Not that there is any problem with experimenting, but we must understand what is possible and then interpret the results accordingly.

Dear Vladimir,

Good luck then with this. One should never stop challenging the accepted science. I expect that at this time it is early for this simpler theory you develop to make predictions like EPR. But, there are simpler and more direct tests. For example, if atoms don't absorb photons in quantized units, then we expect that they will also emit photons in a continuous spectrum. But as we know, the atomic spectra are not continuous.

Best wishes,

Cristi

Your point about emission in quanta need not cotradict the loading theory. After all it was Planck himself who proposed it and fought Einstein's point photon concept all the way!

Obviously I am not an expert on this but I really think it is worth studying the material Reiter has collected because it will clear a lot of questions and open new lines of thought.

Cristi: your argument that from the Zero Axiom and the principle of logical consistency is puzzling in puzzling. The Zero Axiom is just the axiom that there. Is at least one contradictory proposition, namely itself. But of course there isn't one such proposition, there are infinitely many. There are round squares is another self-contradictory proposition. There is a tortoise that is not a tortoise is another. I could go on. So the Zero Axiom is really a triviality. All you need to say is that there exist contradictions.

This brings me to a more fundamental problem: which is how you try to use the Zero Axiom and principle of logical consistency to argue for a mother of all possible worlds. Although you *say* that any proposition can be derived from a contradiction, and thus that the *existence* of an entire mother of all worlds can be derived from it, this peculiar feature of the law of logical consistence is only an implication of classical logic: one that has long struck many logicians as absolutely unjustifiable -- which is why there is such a thing as Intuitionistic logic which does *not* permit the derivation of any proposition from a contradiction. Thus, if Intuitionistic logic is correct, your argument fails. It's fine if you want to say, "Well, I'm only interested in classical logic", but unfortunately that's not an argument. It just assumes that classical logic is correct, despite its having a bizarre implication that Intuitionists reasonably deny. Unless you can give an argument for classical over Intuitionistic logic, it's not clear why anyone should accept your argument.

Marcus,

What I said about Zero Axiom is not part of classical logic, because classical logic doesn't admit contradiction. The principle of logical consistency may be part of classical logic, but contradiction can't. Why the only alternatives considered should be the ones known at that time? In fact, paraconsistent logics are more suited to admit contradiction and avoid the principle of explosion, so why referring to intuitionistic logic and not to paraconsistent logics?

"If intuitionistic logic is more defensible than classical logic (as I and many other people think it is), your argument fails." Even if classical logic is less defensible than intuitionistic one, for an argument to fail, it has to be proven false, it is not enough to be less defensible. For example, it is more defensible, from many known examples, that the Goldbach conjecture is true, but this doesn't count as a proof, and doesn't exclude the possibility to be false.

Best regards,

Cristi

While from Axiom Zero we can obtain the possible worlds by using the principle of logic consistency, Axiom Zero itself stays outside of these universes. So, the internal logic of the universe may very well be intuitionistic. There are two different levels, which should not be confounded, that of the chaos caused by Axiom Zero, and that of the internal logic of each universe.

The underlying point here is about context. We can only consider existence as manifest to us. Nothing more, because we cannot know more. There is always the possibility of alternatives, if A there is always the possibility of not-A, but these are irrelevant for science. Always watch for an argument which presumes these alternatives.

Hi Cristinel,

Looking at Wheeler's delayed choice experiment, do you get the sense that there are real wave-functions that are being created (by opening the slit) and collapsed (by closing the slit), such that the waves-functions appear/vanish faster than the speed of light? In other words, wave-functions are the mathematical "bit", but they also exist as the "it", and are not restricted by the speed of light.

Has anyone thought of toggling between particle and wave (particle-wave duality) using the Wheeler delayed choice experiment for use in FTL signalling? In other words, opening/closing the second slit creates/destroys the second wave-function. The second wave-function is what is interfering with the first wave-function and causing the interference pattern.

Creating/destroying wave-functions can be done to transmit, not information, but patterns, faster than light. On the receivng end, you need a way to determine (a) is it a particle pattern = 1 or (b) is it a wave-pattern = 0.

There is no reason why you can't place the photon detector a distance of several light hours away. Then, you open and close the second slit to transmit a digital code: 1010 0110...

If delayed choice is true, then the wave-particle-wave-particle pattern should be transmitted instantaneously (faster than light).

Anyone?

Cristinel or anyone! Doesn't Wheeler's Delyed Choice suggest that you can toggle on/off an interfering wave (like a light switch); only you're turning of/off/toggling a wave-function that can produce an wave/particle pattern as an observable, even after the photons have passed the slits. That's why it's called "delayed choice". It implies that you can produce an observable faster than the speed of light.

Hi Jason,

If we think that the waves were there, and then our last moment choice affected them, it seems like they change instantaneously. But one can't prove that they were there, and they changed as a result of our last minute choice of what to observe. If we try to measure them to see where they are, and we find them there, the interference is destroyed, no matter what we do later. In other words, once we find them in a place, we can't make them rearrange by choosing to observe interference in the last moment. So we can't use this to transmit FTL signals. Like in the case of entanglement (they are faces of the same phenomenon), it is not known a way to send faster than light signals using this.

Ovidiu

Hi Cristinel,

I'm trying to follow you. I could take a laser and shine it on two slits, and the light waves emerging from the slits will produce interference patters. But if I cover one slit, then the interference pattern disappears. I can do this experiment one photon at a time. In principle, I could open and close the second slit in some binary code fashion such that someone at the back of the wall could look at the pattern of (interference pattern),(particle pattern) and know that I'm trying to send a message SOS (for example).

Now I'm trying to understand how the Wheeler delayed choice experiment works. I still think there is a wave-function involved in the geometry somehow. Sorry, I gotta go. I'm just trying to understand how this works.

Hello Christi,

Thanks for reply. No offence meant by 'fan' or 'disciple'...

Yes, life is short but a question that must be answered Yes/No and must come before , "does God exist?" is "does the universe exist?". It is when this is answered Yes, that you then follow up with whether God exists.

Similarly, with Schrodinger's cat, before asking whether it is dead/alive, the question as Wheeler says that will be at the "very bottom" before asking this is, "Does Schrodinger's cat exist?", then if answered Yes (1), you can then ask whether it is dead (0) or alive (1).

To Leibniz, he attributed 1 to God and 0 to 'nothing', but essentially as Barbour says in his FQXi essay, bits 1 and 0 MUST stand for something very concrete and fundamental.

I am grateful for those references. I will surely look them up.

Happy to be your acquaintance (or is it your disciple) online... :)

Christi,

Beautifully written essay. You take the counter case to my own, which is refreshing, and argue it very well, I certainly hope and expect you'll be in the top few this year.

I hope you'll read mine and comment on the counter arguments about mathematics, and also the delayed choice statistical findings. I propose the experimental evidence, found in two different ways, of the quantum eraser case can de explained without delayed choice by using a different starting assumption to Wheeler.

I won't repeat it here, but I propose that using and correlating 'individual' entangled particles with time separation in the EPR case will give access to the additional information that exists to prove Von Neumann's thesis for a more consistent QM. i hope we can discuss this if you manage to read the essay.

Very well done for yours. I wish my arguments was as clearly presented.

Best of luck

Hi Christi,

It was refreshing to read your very well written essay. And I think the construct with Axiom Zero was very elegant, but we still need to find the logically consistent subset that matches our observations don't we? Which luckily further narrows down the subset.

Could I ask you the favor to read and question the logic in my essay, where I try to explore possible subsets? I wrote it to get constructive feedback but many comments seems to trail of with themes that are not really a part of it. (And I already apologize for it to be substantially lesser well written than yours - and for advertising it here.)

Dear Cristi,

a very good essay with a great overview about Wheeler's ideas. I agree completely. Your global consistency principle reminds me on my topological condistions. So, our approaches should be related, see my essay.

Your whole ideas have a strong touch of mathematical logic, like topos theory. In particular Axiom Zero looks like the usual contradictions used in the proof of Gödel's incompleteness theorem.

This is a very well written essay and I had to go back to Wheeler 'law without law' writings to fully appreciate it. I also found 'We have clues, clues most of all in the writings of Bohr, but no answer'.

You said "At least I am confident in this view and I think that quantum contextuality is a concept close to Wheeler's view but may be not as radical as the 'law without law' dogma. What is your opinion?"

I think my position is close to yours. I think that what the delayed choice experiment exhibits is contextuality, and one cannot directly infer "it from bit" and "law without law", which indeed are too radical. That's why I emphasize the interplay between information and ontology. I express this by the ideas of delayed choice initial conditions and global consistency.

I read your essay and I like it very much.

Dear Cristi,

You offer another excellent essay food for inspiration. Because I am convinced that we follow - more or less - the same way seeing into Nature allow me to pose few suggestions as interpretation between our views.

You propose the law of no law and the zero axiom. They are both right although could go a long way forward if they are combined.

The low of no law is related to two independent factors. First the position and state of observer (e.g. variety of "constants" in relation to the Universe's age) and second the real or virtual reality the law is applied into. According to the latter differentiation, the law acts in exactly the opposite manner and not just alterably (e.g. impulsive or repulsive gravity). This is related to zero axiom in the sense that going to elementary level examination, the difference is expressed by opposition (+ or -) in Nature. This differs from the notion of existence or not, that implies to 0 or 1 for a bit. No existence is the existence of two or more (2n) opposite existents, n of them in certain state and the rest n in the opposite one. This leads also to the unlimited division (of no existence...).

Good luck,

Hi Christi,

I really enjoyed reading your essay, it is one I printed out.

"The Big Book of the Universe" remids me of "The library of Babel" by Jorge Luis Borges. You mention that this book contains "every" truth, but what with the not true ? There is a lot in our universe that we see as true but it may be untrue. That is why I created so called "Total Simultaneity", where every probable, unprobable, possible , impossible (for us) universe "IS", however I agree that I cannot describe this "environment" with words or formula's (because they are causal and TS is non-causal).

In my essay : "THE QUEST FOR THE PRIMAL SEQUENCE" I try to go deeper in the ocean of "reality", but I feel like a grain of salt so I melt before I can reach any depth.(http://belurmath.org/gospel/chapter03.htm thank you Don Limuti).

Hello, Christinel,

I was interested, as many others, in your approach to Wheeler. I am on the other side, as you will see if you read my essay, but would like to question you on a couple of things, if I may: what is the basis for saying that the universe asks us only questions with yes-no answers? Many of the questions I get asked in life have much more complex answers. Also, regarding the Tao as a model of It-Bit: the discussion of the Tao often refers not only to yang and yin, but to their conjunction (or join). How do you take this into account?

I am on the other side, as you will see if you read my essay, but would like to question you on a couple of things, if I may: what is the basis for saying that the universe asks us only questions with yes-no answers? Many of the questions I get asked in life have much more complex answers. Also, regarding the Tao as a model of It-Bit: the discussion of the Tao often refers not only to yang and yin, but to their conjunction (or join). How do you take this into account?

Best regards,

Joseph Brenner

P.S. My logic derives from that of Stéphane Lupasco. If this name means something to you, we have a further basis for discussion. JEB

Dear Joseph Brenner,

Thank you for the comments. You consider that you are on the other side, but I can't see what this side is, given that I don't think I am on one side or another. Probably I will figure out your side from your essay. Anyway, I often take a neutral position and find myself interpreted as being "on the other side". When asked questions like "it from bit, or bit from it", I try to find a viewpoint that keeps the best from both. My habit of taking the position of going beyond dichotomies attracted me some years ago to read Stefan Lupascu's "Logique et contradiction" and "L'expérience microphysique et la pensée humaine".

You ask "what is the basis for saying that the universe asks us only questions with yes-no answers?"

What I actually said is that we ask questions to the universe, and the answers are yes/no:

"what we know about the universe comes in yes/no answers to our interrogations"

By interrogating the universe I meant perform observations and experiments. While the questions we have are more complex than those requiring yes/no answer, to get an answer from the universe, one has to frame them as yes/no questions. Of course, one can measure a position, and we will get a value of say x plus/minus an error, but this answer is just a more complex combination of yes/no answers: we never get the precise value of a continuous parameter, just an interval obtained by dividing the set of possible values.

"regarding the Tao as a model of It-Bit: the discussion of the Tao often refers not only to yang and yin, but to their conjunction (or join). How do you take this into account?"

This is precisely what I did in my essay, in which I argue that there is in fact an interplay between 'it' and 'bit'.

Cristi

Hello Cristi,

Reading your essay was greatly enjoyed. When my essay posts; you will see there is broad agreement on the major points. However; my offering is philosophical and non-technical, while yours says some of the same things with precision. An excellent offering overall. I'll probably have more to say later.

Hello again,

I wanted to thank you for emphasizing in your essay that It from Bit comes out of the Participatory Universe idea, as a kind of outgrowth of the measurement process. This is something I emphasize the importance of in my own essay, but I did not fully grasp that some of the perspective I recommend was part of Wheeler's original conception of It from Bit Physics.

I think too many assume incorrectly that Wheeler was merely re-stating the digital or computing universe concept, when what he had in mind was probably a little different. I thank you for pointing out the historical relevance of Wheeler's work, and the caliber of his more successful students. Invariably; breaking new ground requires bold thinking, and JAW was certainly a champion of that.

Have Fun,

Jonathan

Dear Jonathan,

I want to thank you for reading and commenting my essay. Indeed, too often some ideas propagate in a distorted or misunderstood form, and few have time to go to the source and check with careful consideration. I guess the problem is that there are so many interesting things to do and read in life. This competition is a good opportunity to go back and (re)read some of Wheeler's works. I am glad if I could shed a little more light on the subject. I am looking forward for your essay.

Hi Cristi,

If particles, particle properties (its) are both cause and effect of their interactions, of the exchange of information, of bits, then you cannot have one without the other. If particles, particle properties (its) only exist, are expressed and preserved in their interactions, in the exchange of bits, then the bits are no more fundamental than the 'its' so you cannot have one...

So the delayed experiment doesn't change the past, nor can it be seen as ''switching in the last moment the web with another kind, while the insect is still heading toward the web'': if with ''insect'' we mean a photon, then it arrives at the web the moment the web is 'switched' on.

If atom A emits a photon which is absorbed by B, a transmission which changes the state of both atoms (and hence affects all particles within their interaction horizons), then A 'sees' B change at the time it emits the photon, as soon as A changes itself so sees a slightly changed world, whereas B 'sees' A change at the time it absorbs the photon, as it changes itself and hence the world it observes. That is, unless we believe that B, after absorbing the photon sends back a message to confirm the receipt of the photon, a thank-you-note informing A that it can, as of this moment, the receipt of the note, start to see B in its new state. While BBC assumes that the emission of the photon by A precedes its absorption by B in cosmic time, in a SCU both A and B are equally right about the time of the transmission, in which case its transmission must be instantaneous. The fact that we cannot experimentally determine whether c must be conceived of as a (finite) velocity of light or as a property of spacetime (a number which says how many kilometer pace distance correspond to one second time distance), combined with the fact that an instantaneous action-at-a-distance would solve most if not all riddles of quantum mechanics like entanglement, the EPR paradox and the double-slit experiment should at least give pause for thought.

Dear Anton,

I appreciate you posted here such interesting comments, which present a critical view on causality. I think causality has its roots more in our daily experience, and in classical mechanics. This is so rooted in our minds. Theory of relativity and quantum mechanics, were so difficult to understand, hence were initially resisted, mostly because of our preconceptions about causality. Wheeler's delayed choice experiment was intended to show that causality is not what it used to be, so to speak. This doesn't mean that delayed choice experiment shows or claims to show that we can change the past, this occurs only because we assume that the past was in a state, which was then modified, as in the grandfather paradox. "No phenomenon is a phenomenon until it is an observed phenomenon."

Evolution equations are local, and the solutions exhibit local causality, which seems to be violated by quantum mechanics. I proposed that the "global consistency principle" explains this, by constraining local causality so that, globally, there is no conflict. So, global consistency comes first, and local causality later. Local causality is just an illusion of an observer who perceives time as flowing. In the block universe, in which time is just the fourth dimension, as in relativity, global consistency is natural, and local causality emerges only when you go to a dynamical description, in terms of a flowing time. When you tell a 4d story, things look natural, but when you tell it as a 3d story evolving in time, causality becomes manifest, and then appears to be broken by quantum nonlocality and delayed chocie experiments, and we conclude that there are paradoxes. But this is an illusion.

Best regards,

Cristi

I'll summarize here.

There are several points of strong agreement between your essay and my own (yet to be posted), which figure into my current line of research. To enumerate...

There is an interplay between 'it from bit' and 'bit from it' roles at work.

There is a realistic middle ground which global consistency assures.

The deep structure of Math is unavoidably influential on natural law in Physics.

Of course; the second point may be true largely because regularities in Math existing outside our spacetime conceptions rule when there is nobody looking, nor any form to influence. What seems not to be grasped is that rather than imposing a strait jacket which dictates a single outcome deterministically, the deep structure of Mathematics assures that there will be sufficient degrees of freedom for realistic outcomes to emerge.

Recent forays have examined projective geometry as the determiner of object/observer relations, and of course this ultimately leads to an explicit connection with the octonions. Does Math like that predate our discovery thereof? I think it's reasonable to assert that; in some way, all realistic possibilities arise from the deep inner structure of Math.

Jonathan

Already something more..

Not feeling like I said enough, I'll mention that part of what disagrees with me - about the common conception of 'It from Bit' - is the sense that either/or choices are enough to determine anything. Wheeler was pretty crafty, with his variation on the 20 questions theme, and it's interesting to see how this introduces a kind of telescoping element that later gets reduced down, but allows a flexibility of interim definitions. This allows the process of determination to be playful. I really like that aspect of the story.

But this description allowing ranges rather than values is fundamentally different from what's normally employed, and is instead more constructivist, heuristic, or lateral thinking oriented. The idea of considering all possible trajectories from A to B requires a non-verbal approach and encourages one to suspend beliefs, in favor of ideas. Something to ponder.

Have Fun,

Jonathan

Dear Cristinel Stoica

You did a great job, I found your essay very enlightening and well structured. I agree in many points with you. What I could notice is that you open several topics and I'm afraid they cannot be addressed in a small essay. In particular, what drew my attention was your discussion of the mathematical universe due to Tegmark since I have also discussed a bit about it in my essay. I do agree that maths are logical relations and that finding the right mathematical structures that describe the observed data is relevant to quantify and model nature, however, what "worries" me is that from mathematical structures one cannot extract intuitive and tangible explanations of the phenomenology. This is the problem that we have, for instance, with quantum mechanics. The theory has been written in a mathematical language such that most people are uncertain about whether the theory is telling something about reality or it's just a prediction machine.

From my view, the formulation of physical theories in terms of pure math (without baggage as Tegmark put it) can only give mathematical (or logical) "explanations" of the world but not descriptions of physical phenomena in the intuitive language that we all humans understand. This is in part what I discuss in my essay. I hope you have the opportunity to read it and leave some comments, I'd appreciate it.

Best regards

Israel

Dear Israel,

I appreciate you reading and commenting my essay. I am happy about our points of agreements.

"what "worries" me is that from mathematical structures one cannot extract intuitive and tangible explanations of the phenomenology. This is the problem that we have, for instance, with quantum mechanics."

I agree with you that quantum mechanics should be supplemented with something. Its formalism ignores anything except outcomes of quantum measurements. But the world in which we live is also general relativistic, there is also gravity. Having a deeper understand of QM (and GR for that matter) would be helpful in trying to unify them. But ignoring anything but outcomes, by applying "shut up and calculate", would not allow us to go beyond these problems. Those saying that we should "shut up and calculate", claim indeed that QM is complete, because mathematics works and makes the predictions. But if we want to supplement this description, it doesn't mean that what we add cannot be mathematical. In fact, all attempts to extend quantum mechanics or to add content to it are based on mathematics (think at GRW, de Broglie-Bohm, TSV, trace dynamics, etc). The fact that the mathematical description of a phenomenon at a moment of time is not enough, it is not necessarily due to the limitations of mathematics, but of our understanding.

"the formulation of physical theories in terms of pure math (without baggage as Tegmark put it) can only give mathematical (or logical) "explanations" of the world but not descriptions of physical phenomena in the intuitive language that we all humans understand."

I am not sure I understand why would be like this. For instance, 1/2 spin, which is elementary and simple, as compared to other things in physics, is well described mathematically, but how to explain it to the "lay man"? One way is to explain the math, this will take time and patience from both sides, but it has chances to succeed. The way without math, no matter how many years will take, will not lead to any progress at all in explaining such a simple thing as spin.

To put it as a joke, I am not sure why God would have choosen physical laws with the purpose that they can be explained in plain language to the lay men.

On the other hand, I think that human brained is a tool for understanding mathematics. Maybe the need for survival made our ancestors search for patterns, make abstractions, make deductions. Anyway, no matter what the reason is, people can learn math. I dare to say that most of us can do this, although for some takes longer, mostly because of our resistance to abstract logical thinking which seems to be disconnected from reality. There is also another reason: after WW2, either math became too much and had to be made more concentrated, or the mathematicians became snobs, anyway, they banished the good old geometric interpretations from mathematics, by calling such approaches "too elementary". Vladimir Arnold, in The antiscientifical revolution and mathematics, attributes this to the Bourbaki school, and he may be right. I think that in learning math, one should keep anything that can help, but after that, get over it in our thinking. For example, humans use fingers when they first learn to count and make simple arithmetic operations, but later they no longer refer to fingers in doing this. Such references would slow down thinking.

So I agree that one should supplement math with something, when we are trying to explain to the laymen. Many scientists try to make their work more accessible by doing this in popular writings, but since science is very active and new things happen all the time, it is difficult to do this with any new idea.

Thank you for your insightful and stimulating observations. I look forward to read your essay.

Best regards,

Cristi

Dear Israel,

It seems we agree at all points you discussed. Yet, at one of them, I feel the need to reply. I said "I think that human brained is a tool for understanding mathematics", and you replied with "Yeah, but according to some studies, there is one hemisphere dedicated to logical operations and another for intuitive ones.". I don't see any disagreement here, since I did not say that the brain is exclusively for doing math (anyway, the brain lateralization is also between math: right hemisphere is not only dealing with intuition, but also geometry). I just meant that and it is not obligatory to translate math into another language for people, since their brain is capable of understanding it. I think geometry is the intuitive part of mathematics, so left-right brain means, from math viewpoint, algebra-geometry. I don't recall of any study showing that mathematicians have only one hemisphere :). On the other hand, as I already said, I am all for using whatever additional means we can to improve understanding, both in research, and in teaching.

Best regards,

I said "I think that human brained is a tool for understanding mathematics", and you replied with "Yeah, but according to some studies, there is one hemisphere dedicated to logical operations and another for intuitive ones.". I don't see any disagreement here, since I did not say that the brain is exclusively for doing math (anyway, the brain lateralization is also between math: right hemisphere is not only dealing with intuition, but also geometry). I just meant that and it is not obligatory to translate math into another language for people, since their brain is capable of understanding it. I think geometry is the intuitive part of mathematics, so left-right brain means, from math viewpoint, algebra-geometry. I don't recall of any study showing that mathematicians have only one hemisphere :). On the other hand, as I already said, I am all for using whatever additional means we can to improve understanding, both in research, and in teaching.

Dear Cristi,

I very much enjoyed reading your well-written and lucid essay, which provided me with food for thought. If I understand you right, you appeal to Wheeler’s delayed choice experiment and observer participance to start with a case for it from bit, and law without law. Along the line though, you make a case for objective realism and a global consistency principle, and end by concluding for the necessity of an underlying it, so that the bits do not contradict. To quite some degree we are in agreement about the final conclusion.

However, I have always been puzzled by the significance and interpretation attached to the delayed choice experiment. Does it tell us something new about the conventional view of quantum theory, which we already did not know without this experiment? For instance, if we could strictly conclude observer participance from here, would it not rule out `observer independent’ reformulations/modifications such as Bohmian mechanics and GRW? But we know that these latter two theories are still in the reckoning. [You might enjoy looking up the proceedings of the recent Bielefeld conference `Quantum theory without observers’ available at http://www.mathematik.uni-muenchen.de/~bohmmech/bielefeld/vi

In any case the above is a point for discussion. I admire the courage and passion with which you have written your essay and wish you all the best.

Dear Prof. Singh,

Thank you very much for reading and commenting.

You said "I have always been puzzled by the significance and interpretation attached to the delayed choice experiment. Does it tell us something new about the conventional view of quantum theory, which we already did not know without this experiment?"

I think that Wheeler's delayed choice experiment doesn't say something that is not implicit in the known experiments. Its great merit is, I think, pedagogical: it emphasizes a feature which, otherwise, is ignored and rolled from one corner of the mind to another, to avoid confronting it. The essence is that what happened in the past depends on how we prepare the measurement device now. Wheeler liked the spectacular conclusion of the observer participance, probably because he liked his conclusion of 'it from bit'. I think we can limit this to the experimental setup, rather than extending it to the observer (although the observer chooses what to observe). He wanted to conclude that this proves there's no 'it', and 'it' is inferred from the 'bit', while I prefer to restore reality, the 'it'. My claim is that 'it' is something that prevents 'bits' from contradicting one another, a 'reality check'. But, the price to restore realism is to make it dependent on the context, and by this I mean future measurements. I like to look at this as a 4D universe, in which events at various positions and moments in time constrain one another (global consistency). In quantum phenomena, when we develop the events in time, the 4D constrains manifests as if the present depends on what we measure in the future (delayed initial conditions).

Does this dependence of the past on the future measurements persist in realistic approaches like GRW and deBroglie-Bohm? I think it does, and I would refer here to Bell's and Kochen-Specker's theorems. Some claim realistic approaches like dBB are ruled out by such theorems. I don't think so, but the price is the same: to admit that the experimental setup constrains the past. Otherwise, the dynamics of GRW and dBB is not contradicted. In fact, I think that even the unitary evolution, as in the Schrodinger's equation, can be maintained without discontinuous collapse, if we accept that the initial conditions are delayed, or that they have to include the future experimental setup (superdeterminism). No reference here to observers, but only to measurement device. Restoring unitary evolution in the theory (without tricks like "unitary evolution is preserved, if we include all the branches corresponding to the different outcomes") is much more difficult than in modified dynamics or hidden variables, because unitary evolution is much more rigid. But even if there is no proof that unitary evolution is preserved, at least we know that it is not obligatory to be violated - the collapse is not necessarily discontinuous.

Dear Christnel

Thanks for the essay. I think what you have written, "I argue that there is in fact an interplay between it and bit. The requirement of global consistency leads to apparently acausal and nonlocal behavior, explaining the weirdness of quantum phenomena" might have a solution in my posted essay but in some how differently.

The "world" or I say as "digital nature" i.e. "It" can be defined as is a product of two inverse sets of ultimately "bits". Therefore some new fundamental constants may emerge to explain that "world" or "digital nature" simply as an interplaying of "It" and "Bits" in cycles.

Thanking once again.

Dipak

Hi Cristi,

Yesterday evening I returned from holidays. I have just finished to read your beautiful Essay which enjoyed me very much. Congrats. I appreciated that you emphasized the important contribution by Zel’dovich and Starobinski to black hole radiation. Although Hawking cited them in his original famous paper, they are often neglected by researchers who study black hole thermodynamics. Another fundamental contribution on quantum fluctuation is due to Parker, who preceded both Hawking and Zel’dovich's group on this important issue.

In any case, I am going to give you an high score.

Cheers,

Ch.

Dear Cristi,

You have written a very intriguing essay. Yours is the second (beside Philip Gibbs') essay that I have read which emphasized the role of consistency in arriving at more . It seems to me that if you consider the action for the Universe as a whole from the big bang to the present in a path integral context it already implies the global consistency principle (could there be any inconsistent, as opposed to incompatible, paths contributing to the action?).

I have to wrap my mind around the proposition that the universe might at the most fundamental level be based on a contradiction. Years ago, I had considered it as mechanism for creating time: Say, you find the statement to have a truth value of T. Then immediately, it is F, thus, the next instant is created because the determination of the new truth value occurred in sequence, and of course it doesn't stop there but goes on.

I did not develop this idea further because I was not sure that it was the right track, but perhaps there is something to it. One concern that comes to my mind is that the zero axiom undermines the global consistency condition. Why should the universe be globally self-consistent if it is at its very roots based on a contradiction?

Anyway, I thought this was a thought-provoking essay. I wish you all the best especially because I recall that last year it does not appear you were treated fairly.

Dear Armin,

You read carefully my essay, and saw the importance I gave to global consistency. And the question how can this be consistent with the axiom zero is justified. The two are mutually compatible, because axiom zero indeed introduces contradiction, but never within the same universe. The logical consistency principle forbids a proposition and its negation to be true within the same universe, they can only be true in distinct universes. As I wrote in the essay, "Axiom Zero gives birth to each possible universe (because of the principle of explosion [...]), but it is not part of any of these universes, because this would contradict logical consistency."

Best regards,

Cristi

As Alexander said Zenkin in his article "The scientific counter-revolution in mathematics»: «the truth should be drawn with the help of the cognitive computer visualization technology and should be presented to" an unlimited circle "of spectators in the form of color-musical cognitive images of its immanent essence ». But for some reason many mathematicians do not agree with this conclusion A.Zenkin. I think you and I are close in spirit to the study.

Dear Vladimir,

I am happy you read and like my essay. Thanks for the reference to Alexander Zenkin. I find myself in complete agreement with the fragment you quote from his interview. I presume that at this time people are in a big rush, since the information increases exponentially. In math for instance, replacing geometric with algebraic formalism, and further with the category theory one, makes compact many calculations, but there is a trade off in grasping the problems. For those who want to take their time and visualize, there are plenty of videos which can help. I'll just give some examples, this, this, and especially this. I expect in time more advanced interactive methods to be developed, and more and more of our knowledge to be visualized like this. This will also help with the problem of the time needed to learn. Of course, the researchers will not have much time to make videos like these with their most recent work, but hopefully the gap will become smaller in time.

Dear Ken,

Thinking at Wheeler's "law without law", and at Tegmark's "mathematical universe", and various landscape scenarios, how could all these possible universes be generated? One way is to think that, since in sum over histories we sum over all permitted histories, maybe we should consider that all possible universe exist. Another proposal is that of Tegmark, that there is an algorithm which can list all of them, so they are implicit in that simple program. An alternative is to consider a pool containing all possible features of a universe, and to select from this pool logically consistent combinations, and obtain any possible universe. At first sight, it seems too much to consider a pool containing all possible possible statements. Of course, in the pool, they can contradict each other, but when a consistent set of features is selected, obviously they are not allowed to conflict. A problem is, why starting with such a huge information, like all possible statements, including their negations? Isn't this against Occam's razor? Indeed. But all possible statements can be obtained from a self-contradictory statement, by the principle of explosion. And this is axiom zero: just a cheap way to generate all possible propositions. Then, the universes are generated by selecting logically consistent subsets of propositions.

Cristi

Dear Cristi,

Source and Observation, is the Cause and Effect; that is in analogue with Tao. Source of information is the action in space-time continuum, in that information is the transfer of energy in particle scenario where as it is the transfer of matter with Hamiltonian in string-matter continuum scenario. Thus in particle scenario the nature information at the source is continuum whereas it is discrete at the observer as the observation is probabilistic rather than realistic. To resolve this paradox on information continuum, we ascribe a generic wave mechanics with string-matter segments in that the Delayed choice experiment is also elucidatory and thereby the string-segment nature of matter may be validated.

Cristi,

Thank you for a very lucid and enjoyable essay. I am very much in agreement with your global consistency principle.

It is also possible to express this principle using bounded Lagrangians. The yin/yang is the reciprocity between the observable consequences and unobservable consequences (erased entanglement information). (See my essay "A Complex Conjugate Bit and It".)

In this way, quantum information theory complements your arguments.

Hi Cristi

Richard Feynman in his Nobel Acceptance Speech (http://www.nobelprize.org/nobel_prizes/physics/laureates/19

65/feynman-lecture.html)

said: “It always seems odd to me that the fundamental laws of physics, when discovered, can appear in so many different forms that are not apparently identical at first, but with a little mathematical fiddling you can show the relationship. And example of this is the Schrodinger equation and the Heisenberg formulation of quantum mechanics. I don’t know why that is – it remains a mystery, but it was something I learned from experience. There is always another way to say the same thing that doesn’t look at all like the way you said it before. I don’t know what the reason for this is. I think it is somehow a representation of the simplicity of nature.”

I too believe in the simplicity of nature, and I am glad that Richard Feynman, a Nobel-winning famous physicist, also believe in the same thing I do, but I had come to my belief long before I knew about that particular statement.

The belief that “Nature is simple” is however being expressed differently in my essay “Analogical Engine” linked to http://fqxi.org/community/forum/topic/1865 .

Specifically though, I said “Planck constant is the Mother of All Dualities” and I put it schematically as: wave-particle ~ quantum-classical ~ gene-protein ~ analogy- reasoning ~ linear-nonlinear ~ connected-notconnected ~ computable-notcomputable ~ mind-body ~ Bit-It ~ variation-selection ~ freedom-determinism … and so on.

Taken two at a time, it can be read as “what quantum is to classical” is similar to (~) “what wave is to particle.” You can choose any two from among the multitudes that can be found in our discourses.

I could have put Schrodinger wave ontology-Heisenberg particle ontology duality in the list had it comes to my mind!

Since “Nature is Analogical”, we are free to probe nature in so many different ways. And you have touched some corners of it.

Hi Cristi,

I enjoyed your essay again. We have been in a few contests together.

Wheeler has what I call a genetic disease. He insists that quantum mechanical objects must move continuously with no gaps in space or time. And yes if this is true then he can have present events changing the past. This is reflected in your diagram of the delayed choice experiment.

Wheeler delays the removal of the second beamsplitter to insure that the photon is past the first beamsplitter. My objection to this is that Wheeler does not measure that the photon is beyond the first beamsplitter, he assumes it, given the way that photons move "continuously".

I believe there is good reason to believe that photons move discontinuously. A photon moves by appearing and disappearing. When the photon arrives at the first beamsplitter it disappears from space-time. It will reappear after a delay and at a distance that is its wavelength.

The conclusion that the present can change the past is then incorrect because the photon is not beyond the first beam splitter after the delay, it is actually non existent and waiting to enter existence again. When it does come into existence again, it is beyond the first beamsplitter.

Yes, this a different kind of QM. There is a logic behind it and experiments can be made. Please take a look at my essay. I would be interested in what you think of my attempt to destroy the uncertainty principle.

Thanks,

Don L.

Dear Don,

Thank you for the comments, and for questioning the delayed choice and describe an alternative explanation. I understand you propose that photons jump in spacetime according to their wavelength ("lambda-hopping"). This seems to me to make, in some situations, very different predictions than QM, so the two can be distinguished by experiments. I will read your essay for more details.

Best regards,

Cristi

Hi Cristi,

Thank you for a delightful description of quantum contextuality.

> Information may not be just what we learn about the world. It may be what makes the world.

In my essay Software Cosmos I construct a picture based on the simulation paradigm. This discrete computational model can answer many cosmological puzzles and has much in common with your "mathematical universe".

> This is why I think that the complete picture is not it from bit, but rather it from bit & bit from it.

My conclusion, "It from Bit, and Bit from Us" also takes in the important role of participating observer.

I hope you get a chance to read my essay, as I suspect you might find it to be a specific realization of your ideas about the cosmos; however, one that is not only mathematical, but computable.

Dear Cristi:

Very nice essay! The idea that our world is fundamentally mathematical is very interesting but I always had one question: What is the role of time? Mathematical objects are timeless and it is not obvious to me how time would arise.

Also: Your axiom zero seems a bit too smart for me. Basically what it says is that the world is something. The fact that you use the language of logic then suggests that you are interested in logically consistent worlds. It would be nice to constrain the world a bit more, wouldn't it.

All the best.

Dear Cristi,

What a lovely essay! It's as good a rendition of the delayed-choice experiment as I've ever seen.

My biggest worry is about the experimental verification of the violations of Bell-type inequalities. I worry that they are actually comparing correlated vs non-correlated probabilities rather than quantum vs classical mechanics. (See my rather lengthy answer to Mauro D'Ariano's comments under my essay.) For nonlinear classical systems can and do exhibit correlations that change their predictions for these inequalities so as to overlap with quantum correlations. (They, so to speak, are obeying Bayesian probabilities.) It this is really true, then I worry about the interpretations of the delayed-choice experiments.

Also, I'd be interested in your speculations about what Wheeler might have done had he been interested in nonlinear dynamics and/or chaos theory.

Again, congratulations on a wonderful essay.

Dear Cristinel,

We are at the end of this essay contest.

In conclusion, at the question to know if Information is more fundamental than Matter, there is a good reason to answer that Matter is made of an amazing mixture of eInfo and eEnergy, at the same time.

Matter is thus eInfo made with eEnergy rather than answer it is made with eEnergy and eInfo ; because eInfo is eEnergy, and the one does not go without the other one.

eEnergy and eInfo are the two basic Principles of the eUniverse. Nothing can exist if it is not eEnergy, and any object is eInfo, and therefore eEnergy.

And consequently our eReality is eInfo made with eEnergy. And the final verdict is : eReality is virtual, and virtuality is our fundamental eReality.

Good luck to the winners,

And see you soon, with good news on this topic, and the Theory of Everything.

Christi - One of the best descriptions I’ve seen yet for Wheeler’s delayed choice. Although I imagine our views may diverge substantially (for example on the global consistency principle), I still gave you top marks for an Outstanding essay. Well done.

I would imagine that the concept of subtime would provide an intriguing explanation of the delayed choice paradox.

I will look forward to following up on your other publications, and reading your PhD Thesis.

Dear Paul,

Thank you for reading my essay, and finding in it things you liked. I read yours too, and see that you put at use a sort of retrocausality. Probably you noticed that I used the idea of "delayed initial conditions", which can be viewed as retrocausality. When understood in terms of 4-dimensional block universe, this takes the form of the "global consistency principle". Solutions have to be global, I don't think there's a way to avoid this. And if this rather tautological truth can explain quantum correlations, even better. Good luck with the contest!

Cristi - thank you for the review of my essay and insightful remarks.

Actually, I would like to make a distinction between retrocausality, and true reversibility, where the state that is returned to is fundamentally indiscernable from having never left that state.

As you have seen from my essay (and my warning of diverse opinions ;-) I have dispensed entirely with the block universe: Minkowski space leads us to the false illusion that time can proceed independently of change along the spatial dimensions. Instead, I consider time/space as extending only down the 1-dimensional path of the traversal of a photon from one atom to another, and reversed, in all ontological respects, when the photon reflects back to the original source. Thus, there is no net change in time/space at the microscopic level.

By the way, your PhD thesis is awesome.

Dear Marina,

Thank you very much for the nice and detailed comments to my essay. If you liked mine half as much as I liked yours, that's fine! About the analogy with fly/dragonfly, I wanted to make it by using some shape-shifting entity, like larva/butterfly, but larvae couldn't fly! And most important, I didn't want it to be interpreted as if the shape-shift took place in contact with the spiderweb. Regarding the quote you mention, about Wheeler and his students being responsible for many preposterous features of our universe, I am not sure in what proportion it was a joke, or a serious statement, or something between: a metaphor describing the paradigm shifts initiated by them.

You said "I do not quite share your idea that our universe is mathematical." That's fine, since, for example, I don't know if it matters whether a line is a line, or just a collection of points which happen to form a line! Important to me is that I expect an element of the collection to be on that line.

Thanks again for re-reading my essay, and for delighting us with your beautiful one (which I hope it will go into the finals).

Thank you Cristi for your sweet reply!

And congrats on making the list. For my part, I'm there not on the merit of my entry but because the 'thumbs' were bombing their competition and so pushed many of the best essays bellow the cutoff point, while mine innocuous entry remained under their radar. I already asked for permission to swap my place with one of those unfairly slighted essays.

I returned here to further discuss your fly/dragonfly analogy. It is very clear to me now that we do not understand light. Neither do we interpret it right => hence paradoxes. Regarding my slight change of your analogy, won't you agree that with a*single* even if weird insect -- rather than 2 types of insects -- there is no paradoxes in either a plain double-slit nor a delayed choice experiment. I.e. we are observing the same phenomenon through different means and so we see its different aspects. But this means that nothing changes retroactively. Do you agree?

Again, congratulations for making the list. Your essay is a good read for SA. Let's hope it gets there,

PS Oh! and regarding your take on Wheeler's PAP -- every joke has some truth to it. I've seen people taking his PAP very seriously. I also see PhD's taking Copenhagen interpretations very seriously (as in 'this is IT' rather than just 'Bit' based on lack of better info).

My congratulations Cristi.

I'm glad you made the finals, and I think your essay will get high grades from the expert reviewers (after all, they are experts). I wish you luck but I don't think you'll need it, as you did an excellent job on your essay this year.

All the Best,

Jonathan

Dear Jonathan,

Thank you, and I am happy for you too! There are probably almost fifty finalists, (and many others interesting essays which are not in the finals), but I hope the expert reviewers will find the time to give them all the deserved attention. I wish you success with your essay!

Best regards,

Cristi

I develop in more detail the ideas of *global consistency principle* and *delayed initial conditions* in a recently published paper,

C. Stoica, Global and local aspects of causality in quantum mechanics.

This is a proceedings paper, for the Conference The Time Machine Factory [unspeakable, speakable] on Time Travel in Turin.

Here are the slides of the talk.

Hi Cristi,

Congrats for the Prize.

You Jennifer Nielsen and Douglas Singleton, Elias Vagenas, & Tao Zhu are the only positive news on the ridiculous and shameful "results" of this Essay Contest.

Cheers,

Ch.
