While we’re waiting for the results of the Nature of Time essay contest, I thought I’d tell you about my own efforts to get a better grip on the slippery sands of time, by chatting to
Dan Falk, a science journalist based in Toronto, who has recently published a book called “In Search of Time.”
Falk’s book examines time from our earliest prehistoric bone carvings all the way up to present cosmological examinations of the subject.
Falk discussed our earliest efforts to record and measure time with ever improving precision, from large seasonal monuments like Stonehenge, to the Babylonian calendar (which had 7 13-month years followed by 12 12-month years), and finally a discussion of the early efforts to make clocks.
However, the most interesting part of the book was when Falk talked about what physicists think and know about time. Falk spoke with many leading physicists—and members of FQXi—including Sir Martin Rees, Paul Davies, and Lee Smolin about time, and the consensus view of time was “a bit of a nonstarter.”
“Amongst the general public there’s some sort of an expectation that physicists would have a really satisfying straight-forward answer as to what time is,” said Falk, “and I think they are a little surprised to hear that physicists have basically said that time is what clocks measure and that there’s just not much more to it than it.”
In his book Falk also talks about the position—that FQXi followers will be familiar with—taken by Julian Barbour, a UK-based theoretical physicist. Barbour denies the existence of time saying that it is all in our heads. (Barbour’s entry to the FQXi essay contest is
here, while Kate Becker has written an article on some of Barbour’s more recent ideas,
“Back to Mach”, which has already provoked some lively discussion on the FQXi forums.)
Personally, I have trouble imagining a mass delusion that keeps us moving forward through time, but judging by the excitement this idea is generating on the forums, I guess it’s quite popular.
Also perennially popular in theoretical physics and pop culture is the final topic Falk and I talked about and that he addresses in his book: time travel.
Of course, the standard paradox that people raise when talking about time travel is: what would happen if you went back in time and killed your grandfather?
This is a favorite discussion among physicists and philosophers. You can check out Falk’s blog for a more complicated version of this, which he dubs
“the Downing Street Dilemma” in which he wrestles with the issue of whether time traveler’s can really have free will. (“Must every rifle aimed at grandpa misfire?” asks Falk.)
He also brings in an interesting question for those who say that people could time travel, but not change the past: “Does it matter how well we know the relevant history? That is, is our knowledge of past events somehow relevant? Would someone who failed History 101 be free to run amok at the Battle of Hastings, while an A-student would have to tread carefully so as to not interfere with the death of Harold and the victory of William? The answer, presumably, is: “No, because the rest of us know what happened there.” But what about a visitor to the Jurassic era? Could our time traveler do as she pleases, simply because so few records from that era survive?”
 |
| Dan Falk |
Falk takes the view, held by a few physicists, that one possible solution to the grandfather dilemma is the existence of parallel universes, an element that is common in a few theories of the Universe. (FQXi blogger Vlatko Vedral talks about looking for evidence of parallel universes in the lab,
here, while Govert Schilling’s article examines
“The Philosophy of the Multiverse”.)
The most intriguing part of my conversation with Falk came at the end of our discussion of time travel, when he added mysteriously that “quantum mechanics is almost too kind to us, but if quantum mechanics weren’t there to save our *sses what would happen? You’ll have to read the book to find out.”
Falk’s book
“In Search of Time: Journeys along a Curious Dimension” is published in the United States and Canada already, with UK editions coming shortly.

I find it hard to understand why sensible scientists are still contemplating time travel. The very existence of the time travel paradoxes shows that the space-time model is incorrect or rather in need of modification.
There already is a really simple and, to my mind, satisfying explanation of how time arises.
If subjective time is to be considered a delusion, then the whole of the reality that we inhabit is also a delusion. That subjective reality is the reality in which science is conducted and is the reality that most people would call real. Rather than denigrate the whole reality of experience with such a negative term (delusion), it should merely be recognised for what it is. It is the inevitable consequence of the interface with the objective material reality, across the Prime reality interface.
Emotion language with negative connotation should not in my opinion be used in regard to a phenomenon, merely because it results in part from an interface between biology and physics. Interdisciplinary science will become of far greater importance as the overlap between the individual sciences is recognised.

Time travel, worm holes, warp drives and so forth involve certain solutions to the Einstein field equations which violate the weak energy condition. The energy associated with the curvature of space can be negative with no lower bound. This means quantum mechanically that the fields which are the source of the curvature have no minimal energy quantum state, and can then decay endlessly down a ladder of states emitting lots of radiation. So this probably puts some limits on these ideas.
The importance has less to do with any real time traveling, but more to get a firm grip on the structure of quantum fields in curved spacetime and ultimately quantum gravity.

I couldn't help thinking you are both saying the same thing, that reality isn't hard and fast, but that it is inherently frayed around the edges, that what we think of as reality is emergent and in trying to peel away the layers, we lose the basic conceptual premises as well.

This points to how quantum mechanical basis for spacetime configurations obeys boundedness conditions. The eigen-spectrum is bounded below, which is what is expected of any well behaved quantum system. The work by Ford and Roman have provided good arguments for a correlation between no time travel and well behaved quantum physics with gravity. The matter is not of course finished, but the work so far is strongly suggestive.

Thank you for those links.
Not only may it be impossible to predict what emerges but we are limited by the information we receive across the Prime reality Interface. If no information crosses from some part of objective reality then it will not form a part of our subjective reality, models or prediction.
It is once again perhaps jounalistic sensationalism to say that all matter is just vacuum fluctuation. Since the dimensions in which we live are actually 4 spatio-energetic dimensions, it really depends on how the idea is expressed. A change in energy is also a change in position in space. Macroscopic bodies are made of particles.Particles change position in space. This can be expressed in terms of energy chganges.
The macroscopic body can then either be described in terms of position in space determined by fluctuating positions of particles or energy fluctuations of individual particles.One description just sounds more exiting than the other but they are essentially the same thing expressed in two different ways.

This example also clearly shows how description given depends upon the model used and which aspect of a subject or phenomenon is highlighted by that model.
I should perhaps say, for those that have not read any of my previous posts...
According to the Prime quaternion model, sub atomic particles are able to pop into and out of 3D vector space by moving directly along the 4th dimension. This movement is equivalent to a change in potential energy. Movement afore is a loss of potential energy. Movement aft is a gain in potential energy.
This movement, as well as movement through 3D vector space (kinetic energy) and spin (which is oscillation along the 4th dimension according to the model) will account for "vacuum fluctuations".

I don't have a problem with time travel. Going back in time we become observers of a static history that we bring into action by our motion through time. However, going forward to the future matters: our 'real' presence can contribute to its events. The past-future time asymmetry is obvious.
Also, curvature (as anti-information content) is the key that leads to everything else; that is, the quantum fields that we interpret substantively...

Georgina Parry wrote on Mar. 6, 2009 @ 07:01 GMT
The past can not have a material existence because this means that every fraction of a second matter is replicating so that it can exist in past and present. Where are the subatomic particles coming from for the replication smeared through out time?
The same problem arises with the multiverse idea. Where does all the matter come from in all of the variations of reality, if the matter of the universe must be replicated numerous times every fraction of a second or whenever alternative possibilities arise?
The historical past is merely due to the way in which the mind works, memories are formed and subjective reality is formed. Relativity occurs because a subjective reality is formed from electromagnetic radiation that has travelled across the Prime Reality Interface. This electromagnetic radiation is just an image of objective reality, not objective reality itself. The image can be observed at different times by different observers but that does not mean that the thing that is seen is still in that place, form or even still exists.
I must also say, while I am here, that I did enjoy Julian Barbour's essay. It was very interesting, educational and well written. It is very interesting to discover how different people interpret things. I can see that there has been a lot of careful thought about the subject which shines throughout the essay.

John,
and I agree with you on that. I could describe a rose flower with as much biological accuracy and detail as possible, whilst also trying to express an emotional connection to its beauty and transitory nature. However good that description is made it will never actually be a rose flower.
The same is true of any scientific model. However good it is at explaining physical phenomena and observations made within the subjective reality as well being self consistent, fitting with other scientific models and answering the fundamental questions, it is still only a model not objective reality itself.
No description and no model can be. They are created by the mind. The question is, if we must have a model to comprehend how the universe functions at all scales, which model, whilst retaining logic and being self consistent, can explain the most.
The Prime quaternion model not only works at a scientific level but on other levels too. It encompasses the constant flow and becoming of the universe and recognition that ultimately everything is a part of the One, as explained by Buddhism and Taoism. It also shows that there is ultimately a Creator of the universe (Quaternion Megauniverse) that is eternal, existing without time from which all matter, structure, forces and subjective time arise.
I therefore,personally, find this model far more satisfying than a model that says the whole universe sprang from a singularity because given infinite time anything can happen and probably does.

How many fundamental questions must a model be able to answer before it is worthy of serious consideration? If all of the fundamental questions are answered, on what grounds other than correspondence with other science, self consistency and logic can a model be judged if it is a model of objective reality, which is by definition unknowable and inaccessible to the scientific method?

I'm wondering if I can draw a parallel here. When Stephen Hawkings talks about information content on the surface of a black hole event horizon, he says that information is conserved. When black holes gobble up stars and dust, the black hole gets larger and the information content increases.
Now, let's take our physical universe. There was a Big Bang, long ago. The four dimensional volume of the universe is expanding. History and memory acumulates; the layers of rock in a canyon tell us information about the past. The number of quantum interactions that have occured accumulate with time. As time marches forward, doesn't it seem as if information is created in time?
Could information content (what Hawkins talks about) be a function of time? Or am I making false analogies?

The total information of the universe, or number of quantum bits probably remains constant. This is the whole idea of the quantum error correction code. What does change on a coarse grained scale is tha apparent decoherence of quantum bits. The joint information between two bits in an entanglement can have negative entropy, but if there is a decoherence which hides the entanglement in a reservoir of states, or behind an event horizon, this negative entropy is hidden. This then gives the appearance of there being more information in the universe. Conversely this process can give the appearance of the loss of information.

It seems like, at work, there is just more and more information to remember, more siutations going on that i have to take into account. That was when I thought of this idea that information grows in time. But I'm sure that's subjective on my part.

For a simple two-state systme the state vector is
|Y) = |0)cos(@) + i|1)e^{i phi}sin(@)
for the angle @ the relative phase between the two states on the argand plane and the angle phi an arbitrary phase between the two states. The two information states are given by the projectors P_0 and P_1 which act on the state to tive
P_0|Y) = |0)cos(@)
P_1|Y) = i|1)e^{i phi}sin(@)
The projectors map out the two quantum bits |0) and |1).
The density matrix |Y)(Y| will contain off diagonal term |0)(1| and |1)(0| which contain the elements e^{iphi}cos(@)sin(@) and are associated with a joint entropy that can be negative. In a decoherence, such as what happens in a measurment these off diagonal terms are removed. The entanglement phase of the system is buried away or lost to the environment. Thie means the information associated with the system appears more "classical-like." There is then the appearance of more information on the coarse grained perspective.

Hi dear all,
Time is a constant in the physical universe and its spheric building.
Personnaly,the travel in time is impossible ,past is the past ,nevertheless some instants foto to see our past is possible ,it's different .For the future ,it's always the spherization logic of building .That's why we are catalysts ,builders ,a application of my spherization Theory is the centralization of skills to improve our common global spheric system ,we could accelerate many processus of major problems on Earth .All s in interactions and has a specific polorizations ,the complementarity to evolove more in correlation with the foundamental spherization.I think that chaos is a short time and dedicated to an universal balance .Let's take the Earth this spheroid and its gravity,its system ,I beleive the real reality is to harmonize ,spherisize chaotics systems or bad systems .An addition of some harmoniuos spheres could change some problems .An important question is how to evolve very quickly ,simply by harmonization and spherization of systems ,in all topics the universality and its foudations ,its laws can improve the balance ,the centralization,the interactions,so many harmonious laws.Let's take some systems like Economy,politic,ecology ,.It's important to analyze all parameters.For exemple here is a work about Malaria ,you see better the global vue I made some years ago ,the natural balance is foundamental .It is a plague in Africa, it is the malaria or paludism, both names are used.
The vector of this disease is a mosquito and more exactly a female, its name is the anophèle.
It is an animal ( R ) / arthropod ( E ) / mandibulate / antennate tracheate / insect / hexapode ( C ) ptérygote holométabole dipteran ( O )
This mosquito female is carrier of the germ agent of the disease.
This dipteran inoculates to the man pathogenic germs
It is necessary to encircle the evolutionary cycle of these sporozoaires, they are unicellular parasites They produce as its name indicates it spores, sporozoaires multiplies by cellular division engendering cells girls.These animal cells are very evolved .Le cycle is rather complex, you should not confuse(merge) the cycle at the man and the cycle to the anophèle, it is different!
I am going to try to summarize it to you
First of all sporozoaires reaches(affects) blood vessels, the liver or there is asexual reproduction, these multiplied cells penetrate into globules it is there that there is access of fever by reproduction végétative or schizogonie in the blood.
Of more then these cells differ in male(mate) and female, and if there is sting(injection) (saliva) of a reached(affected) subject, then the fertilization takes place in the stomach of the mosquito and the egg in the anophèle by sporogonie can multiply again and the cycle continues
It s very important to understand(include) indeed the evolutionary cycle of this devastating disease.
Thus we can notice that this animal is at an evolutionary stage(stadium) important using animal bodies as hosts to allow its cycle to close. It is necessary to prevent this cycle.
It is rather complex I am aware(conscious) but essential there to fight effectively against this disease, the cycle must be understood(included), this plasmodium hémosporidie is a redoubtable pathogenic agent.
How to manage to decrease considerably this devastation.
Thus let us summarize the anophèle which carries(wears) the disease in her, it is the vector,
It is important to know that these dipterans reproduce in stagnant waters and that their reproduction is a function of parameters such as the temperature, the photoperiodicity.la genetic in ........
..
Thus we know or it reproduces, and which are factors(mailmen) speakers.It is important to note that these mosquitoes are the preys of certain animals such of the hymenopterans and more specially vespidas (wasps, microwasps) If it is difficult to check(control) swampy spaces because too big, know that some diverse animals are predators of larvas of mosquitoes or dipterans.
These animals are numerous and of several families:
1/Of the birds,
2/of the aquatic animals miscellaneous,
3/of the arachnids ( épeire ),
4/of the predatory larvas.
Let us summarize: insecticides are useless and polluting and especially destroy(annul) the ecosystem which could fight effectively.
I think that abuses in products phytopharmaceutiques destroyed(annulled) certain regulating ecosystems, more mosquitoes reach(affect) one certain resistances, it is necessary to stop the use of these molecules, the whole is to reduce the potential of this disease by preventing him(it) from following its evolutionary cycle.
Or to prevent the sting(injection) and the reproduction of the vector is Anophèle.
Which are the conditions of fight(wrestling):
Repulsive in targeted zone and on human being (possible with vegetable urticacées family). This vegetable family as well as certain long-lived gerania possess properties of very interesting fight(wrestling) against this insect.
Predators adapted in zone to risk and stagnant waters
Re-energization of the weakened ecosystems
Control of the periodic zones
Look for stagnant waters and to prevent itsreproduction, analysis of the vector ecosystems.
Insertion predators' periodical of the dipteran.
It is possible also to find a pathogenic agent in Anophèle, maybe to sporozoaires cnidosporidies, to invert the situation in its disfavour with a plasmodium destroying(annulling) the anophèle.
There also a vector must be found, certainly to certain micro-wasps.
The control of the ecosystem will eradicate the disease easily I think with a spherical global and logical methodology. It is the colonization of the mosquito that it is necessary to eradicate. Geostrategy and simulations: track down the geographical points sources(springs) of the vector, the oxygenation, the improvement of the predatory ecosystem of the dipteran, the oxygenation and the contribution bacterial reasoned about swampy thorough vase(mud) and zone, what will allow a biodynamics which will fight(dispute) the colonization of the larvas of said vector mosquito
This unicellular plasmodium possesses a cell with a nucleus(kernel) of DNA soaking in its cytoplasm. The membran cytoplasmic bounding the cell.
This protist possesses a totipotence what means that she can engender her genetic equal.
If we go a little farther to the young all this is a polarization of proteins and enzymes making a specific being.
Amino acids order by polarization to define what is given by the genetic information. We can ask this question which is the mark(brand
which protein or sequential imprint of amino acids intervenes in the cellular division. How to block(surround) its totipotence. These questions are interesting I think.
We have to work the ecosystems in accordance with a global logic:
The studies of sites in stagnant waters will be worked in a detail more than importing(mattering), the The problem is that they are abandoned, while the work of those this would end not only in a considerable decrease of the palu but also would allow exploitations(operations) for the bordering inhabitants, it is really this global nature which is important to set in first consideration.
It is important also to know that used medicines are the fruit of multi-national eager for profitability,whole is to revitalize the ground and to plant intelligently. We have to add the systems and to allow a result(profit) of more than 95 % of decrease of vector is the mosquito female, The multiplicity of the vegetable variety will be optimized to reach an opposing biotope to the vector,
The added predators shall reduce considerably the devastating effects of this plasmodium protiste agent of the disease, the oxygenation is very important and will allow convincing results(profits), it is to be known(to know) They do not understand(include) the global nature of the problem, they focus on medicines without acting on the vector products phytopharmaceutical they destroy(annul) the ecosystems which can fight naturally against the anophèle and its piqures innoculant the pathogenic agent A single solution does not exist but indeed an addition of solutions for an eradication or a decrease very important, this small work of summary I hope will allow of these diseases ,It s very important to understand the globality .
I show you that because it's important to understand all sciences ,all physical systems .What is the best solution to evolve quickly ???
Let's unify all systems ,it s everywhere the foundamental spherization.To solve chaotic systems on Earth the spheric evolution is important to put into practice because all is linked and in interactions,there is an ultim connectibility.
Galaxies too will be a spheric state in the time ,but when ,it's an other story .Our Universe has its center and galaxies turns around this cenetr ,the mass increase ,I think that some exponentials are possible and can accelerate interactions and the spheric building .
Some works are interestings .Thanks to all .
I don't speak a lot about the humanist message of the spherization here on FQXi ,
In fact I work on XING platform since 2 years ,I created some groups ,at this moment I work on the creation of an International Humanistic Sciences Center named Unified Sphere,many skills and humanistic point of vue are on this group .Many friends very interesting .All are welcome for optimum synergies ,

Steve,
While overall knowledge is a cumulatively expanding sphere of interlocking insight, the individual's ability to process it is still serially proscribed. So in order to effectively interact with other individuals, you need to edit your insights as forthrightly as possible, or they will do it automatically and specific points you may consider of primary importance get overlooked.
That said, you do manage to draw a specific insight from an extremely diverse perspective. Keep it up, but remember; Information is knowledge. Wisdom is editing.

Myke,
I'm also working with the curvature / generalized angular momenta idea. Could you briefly explain why you identify "anti-information" with "curvature?" I've been treating curvature as information simply because it corresponds to energy/anisotropy; such nonuniformity provides the potential to do work; to communicate. Communication increases entropy as information is spread and the system becomes homogeneous.
With entropy or information content considered to be a quantification of states, we expect entropy increase or increase of micro-states when we follow processes along the "time direction." i.e. single big inhomogeneities lead to multiple smaller ones. The energy or information is "communicated."
Back on topic, I think it's convenient to work with particle-like states for information storage, rather than wave/light-like states which indicate communication. However, under John G. Cramer's Transactional Interpretation (TI) or the holographic principle, etc., the two are equivalent. It seems we are free to choose.
I suppose it's a matter of perspective where we assign the information. In conserved systems, and according to the TI, we know every quantum of information is really one of a pair or higher multiplicity of the state. (e.g. for every infalling quantum of radiation, an event horizon gives rise to the quantum's anti-"particle." - Hawking radiation)
So whether it is the curled state of energy (position/rest-mass/angular-momentum) that I consider informative, or the unfurled quantum (linear-momentum/photon) you consider "information," our viewpoints are symmetric. (assuming the phenomena correspond, "information" vs. "anti-information" are 100% mutual/redundant.) There is no unique information without broken symmetry, so we might say there is no meaningful observation without limited perspective. This is why I struggle a bit with what seems like a "trivial theory of everything." This notion of perfect conservation of energy is essentially the underpinning of supersymmetry, and it reminds me of Feynman's trivial quip, "F=0."
I aim to read your essay soon; we share at least one common viewpoint, even if we take dual perspectives. It should be interesting to see the intersection.

Linear time past-present-future is in the mind. Its physical basis is in the neuronal activity of the brain. Time is a glasses through we experience motion in space that itself is timeless. Clocks run in timeless space. Motion has duration because we experience it through the “glasses of time”. With time all is fine, just we have do not understand fully that time does not exists as a physical reality. Einstein was aware of that, Mach too, Gödel and some other peak scientist. I’m deeply impressed that many of physicists here understand the subject. Once this vision will enter books of physics the whole humanity will transformed. The whole humanity will wake up into timeless universe that we humans experience as present moment. This present moment is always the same. This present moment is eternity in which we exist. Hard to understand, harder to accept, but it is so. ETERNITY IS NOW. This insight will burn religious believes, national identification, racial tensions, this insight is he base for planetary civilization, for peace and prosperity on this planet.
