TOPIC: Spacetime weave - Bit as the connection between Its or the informational content of spacetime by Torsten Asselmeyer-Maluga [refresh]

In this essay I will discuss the relation between information and spacetime. First I demonstrate that because of diffeomorphism invariance a smooth spacetime contains only a discrete amount of information. Then I directly identify the spacetime as carrier of the Bit, and derive the matter (as It) from the spacetime to get a direct identification of Bit and It. But the picture is stationary up to now. Adding the dynamics is identical to introducing a time coordinate. Next I show that there are two ways to introduce time, the global time leading to quantum objects or the local time leading to a branched structure for the future (tree of the Casson handle). This model would have a tremendous impact on the measurement process. I discuss a model for the measurement of a quantum object with an explicit state reduction (collapse of the wave function) caused by gravitational interaction. Finally I discuss some applications of the model to explain inflation and the Higgs potential.

I'm a post-doc worker at the German Aerospace Center. I received my PhD at Humboldt university. My research interests are wide-spreaded from evolutionary algorithms and quantum computing to quantum gravity. Since more than 15 years I try to uncover the role of exotic smoothness in general relativity and quantum gravity.

Dear Torsten,

I enjoyed your essay, although topology is not my strong suit. You speak of changes of state caused by an interaction in which it implies bit. I agree with this view.

You then analyze experiments in terms of closed curves in a manifold and ask whether the fundamental groups are isomorphic. You say there is no algorithm for a decision: "for two data sets of the...

Dear Eugene,

I'm glad to see your essay which I have to read. I agree that the numbers (as results from experiments) should come together to give a view of our reality. This point of view is strongly related to interpretations and logic, i.e. more in the direction of topos theory. Jerzy (my coauthor) is an expert, I have to discuss it with him.

Dear Torsten,

very glad to see you enter this essay, I've been following your 'exotic smoothness'-approach for some time now (though I can't claim to ever have really sat down and worked through all the mathematical details). I'm also happy to see you dedicate your essay to Weizsäcker---I've already had a bit of a discussion with Phil Gibbs regarding his contributions, especially regarding its and bits (i.e. urs), and how they're somewhat sadly neglected these days. Looking forward to reading your essay, I'm sure I'll be back with further comments.

Dear Jochen,

thanks for your interest. I'm glad to see that you are interested in my work. The essay is more like a program which was partly realized.

Weizsäcker's view had a large impact on my work. I disagree that our space is a simple manifold like the 3-sphere. But Weizsäcker concentrated more on the time-like logic and the derivation of quantum mechanics. Anyone speaks about Wheeler but Weizsäcker was the first and he went further.

I'm looking forward to read your further comments.

Jochen,

I'm deeply sorry for overlooking your answer in my essay thread.

In particular I have to read the refernces you gave. The whole subject is not easy reading, I know it. We (Carl and me) needed 7 years to write the book "Exotic smoothness and physics", in particular to present the topic as easy as possible.

The idea of the usage of wild embeddings as quantum states was born last year before the FQXi essay contest. I understand your problems with "geometrization of the quantum". It took me also a long time to accept it.

But let me clarify, my main interest is in the interplay between 3D and 4D. The introduction of smoothness structures is necessary if you consider the path integral in quantum gravity. You have to integrate over all exotic smoothness structures. It was folklore in the 90s that the man contribution came from the exotic part. But no one was able to proof it. For the exotic R^4 I'm not far away to proof it.

In my whole work I was driven by "naturalness". The next structure afetr the topology (before geometry) is the smoothness structure which is not unique in 4D. Therefore one must consider them.

I also enjoy reading your essay and I agree in most points. I'm also glad that you also like Weizsäcker (which is mostly forgotten in the physics community).

All the best for the contest

Dear Torsten,

Excellent essay! In my opinion, your program, as described in the essay, is very much in the spirit of Wheeler's dream "it from bit", and of Weizsacker's ideas. I have a lot of questions, but I think I will get answers to many of them from your papers. I hope to make more time to go carefully through all of them in a couple of months or so.

Good luck!

Hi Torsten,

This is very nice to see you here. Excellent essay! In my 2011 FQXi essay I have used your publication (Torsten Asselmeyer-Maluga, Helge Rosé. On the geometrization of matter by exotic smoothness. arXiv:1006.2230v1) in references. That is very rare that academic entrant, as you, accepts physics as a manifestation of geometry. Even though barely all of physicists accept General Relativity they also accept a sudden jump from the big distance scale (GR) to the small one (QM) and the geometrization disappears. What about the distance scale invariance of the laws of physics? No one matters. It is explicitly showed in the ratings of essays.

In my essay in Table 1 I have defined that the conformally flat spacetime is the Bit and the matter is the It emerging from the spacetime but the reverse way is also possible. The matter and space have the same root (ancestor, predecessor). As you see we generally agree. Differences are in technical details.

In my opinion we need to find the one, universal, distance scale invariant metric, reducing to Einstein GR metric within Solar System distance scale and having ability to generate predictions. The first prediction of my (and also yours) concept is my spin experiment outcome. Then depending on the outcome we shall create the proper metric. The progress I have made since 2011 is that experiment.

Best regards

Hi Jacek,

yes I read your paper about the experiment. But I don't understand why the two photons have the same spin. I understood the thought experiment (it is not far away from ym own ideas) but how is the experiment and the thought experiment related? I do not see the motivation.

I know the standard theory (going back to Fresnel) but why is your experiment so important?

Lawrence,

interesting ideas. I thought to wait with an answer until you read my essay.

Freedman used the Cantor set to parametrize all Casson handles. I think you had thsi result in mind. The reference to Gödel's theorem is via the word problem, i.e. there is no algorithm to decide whether two finitely generated groups are isomorphic or not. The application of thsi result to 4-mnifolds is the following fact: every finitely generated group is the fundamental group of some 4-manifold.

Yes your are right the E8 manifold is related to the exotic R^4. The appearance of the E8 (equal to the Cartan matrix of the E8 Lie group) is rather mystical. I know it came from the classifaction of quadratic forms but is there a deeper reason? I have to think about your ideas.

I read the first few pages of your essay with some care. It is interesting that you discuss the issue of quantum measurement. This touches on the issue of contextuality in QM.

Mr. Asselmeyer-Maluga,

In your article you write "smooth spacetime contains only a discrete amount of information", are you refering for instance to quantum theory? In that case the gravitational wave is to be observed yet. If you mean every information, then please explain further.

I think I explained this phrase in the text below. But here is an extract: if spacetime is a continuous 4-manifold that one may think that it contains also a continuous amount of information. But as I discuss in the essay, it is not true. The reason is the demand of diffeomorphism invariance which reduces the amount of information to a countable set (which is in most cases finite).

Of course this result has also an impact on quantum theory but I discuss this theory later.

Hi Torsten,

Your essay was excellent reading. I'm unfortunately not fluent in topology but have tried to explore similar ideas with a discrete background independent foundation. It's more like å gut feeling than anything else but I suspect that space-time is structure built with the bits, aka at least one level of complexity above raw bits. Is it room for that in your opinion?

I try to explore these Ideas in my completely non mathematical essay. And think that it should be possible to deduce why we have a velocity limit, and from there why there's no space-time beyond the event horizon in black holes (which is not covered in the essay) Thinking about bits as the foundation can give rise to ideas on how entanglement works, alternative interpretation of what happens in the double-slit experiment. Even how physical laws arises.

If you would take time to read it - and shoot it down if you like - I would be very happy because we have some similar ideas. (I would really like to get some feedback on some of the ideas there - trails of before the interesting ideas there. Probably because it's badly written)

Anyways - excellent essay and best regards

Hi Kjetil,

I agree that the direction of your essay is very similar to my essay. The universe contains a discrete amount of information but (as I discussed) it does not mean that the space or the spacetime is discrete (like space quanta).

The idea that "We must also introduce an element of chance, or our system would be terrible static." is interesting. Dynamics and probability are connected that is in the spirit of Weizsäcker (but unfortunately he wrote nearly everything in german). I also agree that "The relation

between space and matter is also interesting and one of the defining features of space.". I think this relation is much closer than we think.

So, again many of your main ideas are close to my.

Torsten, I feel that I have learnt about an interesting new perspective from your essay. I did not really know what the fuss with smooth structures was about before. Now I understand it a little better.

The idea that physics is derived from topology is an appealing one nut it depends on whether there is any non-trivial topological structure at small scales in space-time. I think physicists have gone to and fro with this idea. In the last few years I think that the boring flat topology has been winning out but with the new Susskind/Maldacena insight that entanglement is related to wormholes, we could see things swing back to non-trivial topologies. In that case the maths of smooth-structures should be a big topic of interest.

My own approach is to start from an algebraic structure and try to derive geometry as emergent. In a sense it is the opposite of your approach, but the real meat is in the relationships between algebra and geometry and relationships go both ways.

Philip,

thanks for your comment. The interesting point with exotic smoothness is that you don't need a complex topology. Also the boring flat R^4 carries exotic smoothness structures (uncountable infinite many). An exotic R^4 looks globally like a usual R^4 but at small scales it can be very complicated.

I also used algebraic structures to understand topology/geometry. But I think it is very complicate to consider algebraic structures like groups by their own. Usually these objacts act on some other object, in most cases a space. You are right the relation goes both ways, see for instance Klein's Erlanger program. But maybe I have to read more about your work.

thanks for your comment. The interesting point with exotic smoothness is that you don't need a complex topology. Also the boring flat R^4 carries exotic smoothness structures (uncountable infinite many). An exotic R^4 looks globally like a usual R^4 but at small scales it can be very complicated.

I am a self-taut (thinking makes me tense) realist. May I please make a comment about your essay? In my essay BITTERS, I contend that reality is unique, once.

Writing about “bits” you stated “The sequence is an expression of the dynamics (of the timed motion of bits) and for a given position in the sequence we know the unique precursor and successor.” (of)

Respectfully, the only way we could suspect that the position of any precursor and successor bit placement was unique would be if the bit was unique. Each real bit is unique once and because each real bit is unique once, it cannot travel sequentially. It can only travel uniquely once. Only abstract bits can travel sequentially because they are not unique.

Thanks for your helpful comment. Yes, you are right, for a sequence the bit must be real. In see the sequences more like sequences of measured results, i.e. I implicitly assume their existence. The ord 'bit' implies it, but I try to follow your approach and will read your essay soon.

Lawrence,

these are great ideas. I also thought about knot cobordisms but not in connection with path integrals and knot polynomials. In the knot surgery above, one generates the infinite number (countable) of smoothness structures by the infinite number of knots.

I agree that the knot controls the amplitude for the transition.

Thanks for bringing to my attention. I have to further think about.

Unfortunately time is a bit narrow right now. I will try to expand on this in greater depth maybe this evening or tomorrow. Ed Witten sees a great foundation to the knot polynomial approach to path integrals. The occurrence of knot topology suggests a Chern-Simons type of theory, where there are underlying cocycle conditions for a L_{cs} = A/\dA + (1/3)A/\A/\A with a quantum interpretation.

The role of the knot polynomial I think is involved with holography. The Lagrangian for spacetime

S = ∫sqrt(g)(R + L_m)dtd^3x + (1/8π)∮ρdS

Here the curvature ρ is evaluated on the null boundary of the spacetime. This is composed of the extrinsic curvature K_{μν} which is K = dP, for P a displacement on the surface, and in addition the CS term L_{cs}. This is a division of a cochain into a coboundary plus cocycle.

Physically the cocyle can be seen according to Lorentz transformations. Near the horizon as measured afar there is a Lorentz contraction of the radial direction. In the (M^3/KxS^1)xS^1 the contraction eliminates the spatial S^1 and this leaves the knot on the stretched horizon. This is a part of the quantum information on the horizon.

I have yet to assign scores. The problem is that some “trolls” have been assigning ones, and this has the effect of making a 5 in a sense the “new 10.” I would probably give your paper an 8 to 10, the 8 reflecting a bit of a problem I might have with something, but with the renormalized score I have been unsure what to do. I decided to give your paper a 7, which reflects a top or near top score with this unfortunate tendency for these “troll scores” that drop everyone’s score down.

Dear Sir,

How do you say that: “Information refers to an inherent property concerning the amount of uncertainty for a physical system.” Information can lead to decrease in uncertainty. But it cannot tell us about the degree or amount of uncertainty. Whether we can have “ALL” information about a system, is doubtful. You cannot apply Heisenberg’s principle to information....

Dear Sir,

thanks for the special instructions.

Information in this context refers to entropy. But what you wrote is not a contradiction to my intention.

I completely disagree with you to obtain spacetime from information. Information is conncetd with matter. We use the abstract concept of a state to express it. But it is our view of the world. We obtain information by measurements, I agree with you in this point. But this information is not connected to an observer. In particular the observer needs a coordinate system to expres the result.

In my essay, I discussed the relation between spacetime and matter. So if spacetime is matter then information as connected to matter should be also contained in spacetime. Nothing more, nothing less.

Dear Sir,

We never said that existence of space-time is due to information, but it is the interpretation of what you have written. In other words, it is the implication of your statement, which we have questioned by asking: “how can space-time ‘contain information’, which makes the existence of information dependent on space-time?” To this we had replied: “The only logical interpretation is, both exist independently, but inseparably linked as observable and result of observation – matter and its property.” Do you disagree to this?

Hello Torsten,

Yes my essay focuses on dimensionality around Black Holes following the Fibonacci sequence. This actually is a consequence of geometry utilised in my theory.

I'd very much appreciate any comments you have on my essay. I agree that the whole world is contained in the number Pi, after all it is infinite, but has a real meaning to the Universe, so is by no means arbitrary.

I've now read and rated your essay - I think you deserve to do very well - great work!

Dear Torsten,

This is a tantalizing essay particularly after my reading of your last year writing. I like much the idea of using the diffeomorphism invariance as a way of classifying the 4-manifolds and their physical relevance.

I have a few questions after my preliminary reading

1)Are you aware of the attempt to see the visible universe as the Poincaré dodécahedral space (a 3-manifold) as reported for instance in http://arxiv.org/abs/math/0502566 ?

2)I am puzzled by your sentence that 'given two fundamental groups we cannot decide whether these groups are isomorphic or not', where does it come from, you cite a paper by Markov in 1958! Is this related to the type of logic undecidability described by Lawrence B. Cromwell in this contest

Dear Michel,

thanks for your interest. I will read you essay soon.

Now to your questions:

1) Yes I knew this model and had an email exchange with Luminet about it. In the last year, we (Jerzy and me) published a paper where we we showe that a Poincare sphere alone cannot describe the evolution but a sum of two can.

2) Markov showed this result by reducing the problem to the word problem in group theory. Beginning with 4-manifolds, one can realize every finitely presented group as the fundamental group of a 4-manifold or higher. The word problem is the statement that there is no algorithm to decide wether two finitely presented groups are isomorphic. Lawrence argues with Gödel but the word problem is more connected with Turing/Church.

Good luck for the contest!

Torsten,

Fascinating essay. I've always questioned the role of topology as a valid description of nature, (actually I challenge ALL assumptions!) but you've now given me a far more rounded view of the subject. As primarily an astrophysicist I've always been struck by the ubiquitous toroidal forms of energy and collections of matter in the QV. (I explore it's quantum implication in terms of orbital angular momentum in my essay).

I particularly find resonance with; "the measurement of a point without a detailed specfication of the whole measurement process is meaningless in GR." Indeed I describe and axiomise a detection and measurement process. also;

"For two data sets of the spacetime, there is no algorithm to compare the two sets. The result of an experiment is undecidable." In astronomy the lack of a relativistic algorithm for inertial system (spatial frame) transitions, i.e. barycentric to ECI frame is analogous.

and; "matter and interaction (as gauge theories) can be described as special submanifolds of the space where these submanifolds are determined by the smoothness structure of the spacetime."

But what scale are you prescribing smoothness as opposed to 'granualarity', or quantization of energy? is 'granule' smoothness a valid topological concept?

I hope you'll read and comment on mine. I'd hoped more suitable for the average Sci-Am reader, but I fear I may have crammed too much of the the ontological construction in again - so it takes careful reading!

Very well done for yours. I found no reason not to give it a top score. Congratulations on now leading by the way! But you have some good competition.

Dear Peter,

thanks for your comment, I'm also sorry for the delay inanswering.

I also like your point of view. It is not totally different to my approach. It contains a lot of geometric ideas, in particular the representation of the quantum state as helical wave. I also have helical states (but in the foliation).

I rated your essay also very high but a longer time ago.

Now to your question about granularity: There is an isomorphism between piecewise-linear and smooth 4-manifolds. Therefore the granularity is not important for the results. Of course there is a limit (lower bound) for the number of used cells to describe the 4-manifold but nothing more.

Really a wonderful entry, which I think very naturally connects the work you've been doing to the concept of discrete information. If I understand things correctly, you diverge from Wheeler's original idea of a "Bit" by using the handle decomposition of spacetime as a *set* of discrete data, rather than the binary YES/NO which Wheeler envisioned. I wonder if you consider this to be fundamental - can we not reduce this set down further to a set of binary questions? Can this be done in a unique way?

Two additional sections I was particularly interested in. Emphasizing that there is not a unique algorithm to differentiate between two fundamental groups is an interesting choice - it suggests there is quite a bit more to talk about. In Wheeler's view I suppose this would mean that the fundamental group is not part of the fundamental apparatus?

You also bring up a result which I was not familiar with, and that is the connection between sphere bundles and the gravitational interaction. It seems that maybe the geometric models you have been working with might provide a path to a proof of this?

In any case, really great entry for the contest; clear, thought-provoking, and novel. I wish you the best of luck!

Chris,

thanks for the excellent question. In my opinion, every discrete information cane transformed into a sequence of yes/no question. But I think you are interested in the concrete example of a 4-manifold.

Has the handle (attached to the 4-ball) an index larger than 2?

Yes: it is a 3-handle

NO: Has it index 2? No: It is a 1-handle

Yes: Now I have to ask question about the attaching of the 2-handle, i.e. you have to ask about the knot. (For instance, use the braid representation of the knot and ask about the generators: Do you produce an overcrossing of the first two strands of the braid? etc.)

For the next handle start again with these questions.

The problem with the fundamental group is a little bit more puzzeling. You can do an experiment to determine the fundamental group. You can also describe this group by yes/no question but you cannot reproduce your experiment. So, the fundamental group is part of the apparatus but you cannot decide whether this group is isomorphic to the fundamental group of the second experiment.

Yes, I have a proof for the sphere bundle/graviton equivalence but it is not in good shape to present it. The main idea is the usage of a Cartan connection. Then one may ask what characterizes a (simple-connected) spin 4-manifold. Using Freedman: the Euler characteristics and the signature. Both invariants can be expressed as integrals over the Euler and Pontrjagin form, respectively.

Then using the sphere bundles and the Cartan connection one can change these invariants into the Einstein-Hilbert action (plus the cosmological constant) and into the other part of the Holst action (with Immirizi parameter).

As soon I will complete this construction you will get the paper.

Thanks for the wishes

I have more of this sketched out. I wanted to write further today, but I got busy reviewing a paper. As for a classical invariant, check out Agung Budiyono's paper. It is the sort of idea of quantum mechanics that sends most quantum physicists screaming in horror. This is a stochastic approach to QM which along with the Bohm QM is weak, but these ideas I think can have their place.

Dear Sreenath,

interesting essay. In particular I like your multi-disciplinary view. I have only some comments:

- I think, that quantum mechanics do not imply that space and time is discrete. We don't know the curve of the electron but the space points can exist.

- Pure mathematics based on axioms but that is not as rigid as it sounds. In particular as shwon by Gödel, every axiom system (expressing or encoding information in a specific manner) is incomplete. It left open a lot of flessibility to change math.

Hopefully more later

I will be absent for the next three weeks

Good luck and all the best

- Pure mathematics based on axioms but that is not as rigid as it sounds. In particular as shwon by Gödel, every axiom system (expressing or encoding information in a specific manner) is incomplete. It left open a lot of flessibility to change math.

Hopefully more later

I will be absent for the next three weeks

Good luck and all the best

Torsten,

If given the time and the wits to evaluate over 120 more entries, I have a month to try. My seemingly whimsical title, “It’s good to be the king,” is serious about our subject.

Dear Torsten,

You have tried a novel geometric approach to solve the problem existing between space, time and matter by identifying space-time first with Bit, then with It (that is matter); hence you could write space-time = Bit = It = matter. But how far this could be true when you say that space-time is a ‘smooth’ four dimensional manifold and out of which you can construct a ‘discrete’ manifold in order to identify it with the Bit? In other words, how do you ‘quantize’ smooth space-time in to a Bit?

Secondly, how do you link the collapse of the wave function to the gravitational interaction? Is it sheer imagination?

Wish you best of luck in the essay contest.

Dear Sreenath,

sorry for the long gap in answering your question (I was on vacation with my family).

Spacetime can be a bit, because the information contained in the spacetime is discrete.It has nothing to do with the quantization of the spacetime itself. So, there is no fundamental length etc. But diffeomorpism invariance enforces us to consider only discrete information. I agree with that it is maybe a kind of quantization of the spacetime.

The link between gravitation and measurement is a conjecture (originally from Penrose). I considered a model for the measurement process. Finally I got a reduction of the wave function from a geometric process (adding a sphere bundle). Now I had to think about these geometric objects. In a previous paper I showed that torus bundles are related to gauge interactions. So, what is a sphere bundle? From the symmetry point of view, I found only one conclusion: it must be a graviton. Currently I work on a real derivation of this result.

Thanks

Torsten

Dear Héctor

sorry for the long gap in answering your question (I was on vacation with my family).

I agree with you that time is connected with dynamics (something changed) and the time of the clock is man-made. But we have to understand how dynamics works and then we also understand:"what is time". As I argue, time is an order element to obtain a place in the sequence of measurement results.

I will read your essay soon.

Hi Torsten,

Thanks for a very informative essay.

I agree with you on the important role that S3 can play in cosmology, and have developed a model using compactified Minkowski space S3xU1 for dynamics. In my Software Cosmos essay the overall picture is the simulation paradigm, and I show how using S3 can address several observational puzzles in cosmology.

Perhaps my model has some usefulness to your research; in any case I would love to hear what you think of it.

The main reason for joining this contest was not to win, but to see if I can get any professional physicist with interest in foundational issues, to evaluate my idea. I appreciate any criticism no matter how harsh, although I do prefer constructive ones. I have rated you fairly high ( I follow up on your work regularly), but as I said I don’t care for rating mine, but that is your prerogative. I will also ask you some basic questions about your theory a bit later.

Nice Paper. Worth reading again.

I liked the introduction to Von Weizsacker. I wish I could read this reference in English.

Similar conclusion to Lawrence Crowell’s paper --> undecidable.

Interesting ideas. I’m not sure if I agree with them, but worth thinking about:

- because of diffeomorphism invariance, spacetime itself is the Bit.

- gravitation enforces the state reduction after a measurement.

I agree, time is the big issue. Wheeler identified this long ago, and the standard quantum formalism in Hilbert space contains hidden assumptions regarding a background for time.

Is this a task for the future? I think other papers in this contest (and previous ones going back to 2008) are likely to have already made major headway on this task.

Overall, the paper covers too much ground. Everything from information theory to Higgs. I suspect the author would have done better to focus and be clear on one or two concepts, instead of so many.

I still enjoyed it very much, and will read other works from this author.

Dear Than,

interesting idea. But did you really think, that Plancks constant (as the main constant of quantum mechanics) is the reason for all dualities? I agree that Bohr considered its complementary principle (which is roughly your first two dualities).

I like the cite of Feynman, but I think he has in mind: simple but complicated enough.

Dear Torsten,

I was informed about your interesting idea of `the geometrization of matter’ by one of the participants. I have, in fact, also used this concept in my essay which may interest you. It has been shown there that the matter fields (as well as the gravitational fields) are represented by the metric field of the so-called `vacuum’ Einstein field equations and the energy-stress tensor is a redundant part of Einstein’s theory.

You claim that spacetime is the Bit. What about matter in the new perspective?

Torsten,

That post was mine. also let me ask you this as a mathematician. In my system theoretically I must throw infinite numbers of lines, and if you take a very small region it will contain dense almost infinite numbers of points. Does that constitute a a true continuum or it is still discrete no mutter how many points there are?

at first to your question: a line is continuous i.e. it has a continuous number of points. It doesnt't matter how long the line is.

You need an uncountable number of points to form a line nothing less.

Torsten,

Thanks for your reply. Of course the line segment has uncountable points, that's elementary. But My question was (more clearly) that if I pick infinite random points on a that line uniformly, would I cover all the points on the line? My guess is that it will not since you have irrationals and maybe some other problems. Is that correct? I hate to make this a forum, I won't feel bad if you don't answer.

Dear Torsten,

Seems I am reading some of the best essays last! Very nice entry.

Your arguments are quite sound from basic physical principles and GR viewpoint.

My own arguments are more from a philosophical perspective and not as quantitatively argued but I think there are still similarities in our picture. Like you I agree time will bring out the discreteness in continuous space picture, if that is what you mean by foliation. I also discuss a linkage between Time and Existence at a discrete level, although from a philosophical view not from that of a physicist.

I very much agree with your plan to derive matter from the space, i.e. the geometrization of matter. This should be one of the next goals of physics. I myself have started thinking along this line.

Following additional insights gained from interacting with FQXi community members on my essay, I posted on my blog the judgement in the case of Atomistic Enterprises Inc. vs. Plato & Ors delivered on Jul. 28, 2013 @ 11:39 GMT.

Dear Akinbo,

thanks for your words. Yes my intention is to uncover the geometric origin of matter. In particular, I try to obtain it from simple assumptions like the use of exotic smoothness structures.

Unfortunately, I had only time to skim over your essay. There are parallels to my view and I'm glad that you notice it. I have to read it more carefully because it is more philosphically.

Dear Michel,

yes, I read your essay but was on the vacation before I had the chance to write you. I like your geometric model very much (I rated your essay long ago with maximum score).

Now after a second reading I have some questions:

- You used the dessin d'enfants to visualize the contextuality. I understood the Mermin square but how did I see it in dessin d'enfant (Fig. 3b). Is it the number of half-edges (odd number) which produces the contradiction?

- Why is the transitive action so important? In case of a non-trivial orbit, you can check every point seperately.

One remark about the triple 0,1,infty: In the projective geometry, you always have the invariance w.r.t. the inversion operation. In the context of your model it means you have the operator and its inverse operator. Then 0 is related to infty and 1 is related to itself via inversion.

Thanks in advance for the answers.

Dear Torsten,

Thanks for your careful reading.

1) It is not straight to see the contradiction in the dessin of Fig. 3b, I failed to see it in general (for other contexts). Also there is not a single dessin leading to Mermin's square but many, why is it so? More work is necessary. This non-bijection is general for most geometries I have tried to reconstruct from the n-simplices to projective configurations such as Desargues, Cremona-Richmund (i.e. the doily W(2) of two-qubit commutatitivity) and others.

2) You are right that transitive action may not be a necessary condition. The geometry is constructed by having recourse to the stabilizer of each point in the permutation group relevant to the dessin.

3) Last remark, the geometry is of the projective type not the dessin. Here you have to refer to the theory that is well explained, for example in Lando and Zvonkin (my ref. [6]).

Torsten, please check that you vote was recorded.

Dear Torsten,

I am trying to better understand your deep essay but it turns out to be quite difficult accounting for my poor knowledge of differential geometry.

I have a naive question. The (first) Hopf fibration S^3 can be seen as the sphere bundle over the Riemann sphere S^2 with fiber S^1. Could you explain what is the sphere bundle S^2 x [0,1] that you associate to the gravitational interaction? May it be considered as some sort of lift from dessins d'enfants on S^2 to S^2 x S^0, and the latter object lives in circles on S^3, right?

I have in mind Matlock's essay as well.

Dear torsten,

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.

I see that we have some common interests, and will therefore read your essay with interest. In the meantime, I thought I'd direct you to the discussion thread I opened up on Ken Wharton's page (near yours at the top), because that pretty much outlines how I think a geometric description of the observed expansion rate should be handled.

Dear Torsten,

I found your essay intriguing in many ways, yet highly technical (unfortunately, I think beyond the scope of this contest in that respect). I was also puzzled why, when you've already assumed a model that is spatially homogeneous and isotropic, you would be interested in recovering inflation? It doesn't seem to fit.

But those two things aside, you have some very interesting results, and I see a lot of overlap with what I'm thinking about, although we're approaching the problem in some ways differently. I wonder if, when the dust settles here, you'd be interested in reading through the discussion thread I began on Ken Wharton's essay page and emailing me your thoughts on what I've put there. I think I see a possibility from your essay that would really be of mutual benefit, and I imagine you'd pick that out as well from my posts.

As I said, interesting and intriguing essay. I rated it accordingly. I look forward to hearing more from you.

Greetings Torsten,

I found your essay deeply meaningful and engaging. It was not light or easy reading, but I found myself learning something meaningful with each paragraph I read. I think I was able to understand most of your technical points, although the depth of your coverage was astounding, which attests to the clarity of your exposition. I especially like the observation that the smooth and triangulated or PL constructions of the manifold are equivalent, and find greatly satisfying the idea of a tree-like branching spacetime.

There is much to like about your essay, and I gave you a high rating. I had started to read it at least twice before, but it was so dense with content as to take as much time as 3 or 4 lighter ones. However; I felt I needed to come back to it, before the deadline, and give you your due. You might enjoy my essay as well. I'll say more later, if there is time. Good Luck!
