  • There May Be a False Assumption in the Minkowskian Geometry That Led to Block Time, Which Disagrees With Quantum Theory on Whether the Future Already Exists - A Short Look Through the Clues About Tim

Hello Vladimir,

sorry, I didn't find your reply until just now. Thanks. Block time has time as a dimension, and the universe is a frozen 4-dimensional block. This comes out of Minkowski spacetime, and causes so many contradictions that something else may well be needed.

I wouldn't try to remove the Gordian knot of this puzzle without replacing it with something else, as you say. But I've mentioned a few clues about what the starting point might be, and it seems to me that motion through time must be real somehow, so that could be a starting point. This general avenue is comparatively unexplored, as block time has drawn attention away from it. So that's my area of interest... good luck with your work, both artistic and scientific.

best wishes, Jonathan

It seems to me, an admitted lay observer, that the basic problem you demonstrate between block time and time in motion gets down to causality versus conscious. If the universe follows a set of cause and effect and consciousness is not real, then the future can be predicted - aka block time. If consciousness is real (separated from what we understand to be the physical universe), then it seems to me that consciousness, unpredictable as it is, interjects an unknown factor of causation into a otherwise predicatable cause and effect physics equation, and the future is unknown, thus supporting a time in motion theory.

Hello Chris,

thanks for your comment. It seems to me you're talking about the question of whether consciousness affects what happens in quantum theory. As I mention in the essay, I think when you have an unsolved mystery, the first thing to do is to admit it's an unsolved mystery. How we should interpret quantum theory is an unsolved mystery, and like with the mystery of time that I've looked at here, the good thing about facing up to the fact that we don't know the answer, is that you can then start working things out about what kind of answer it might be. That's like looking at the holes in the jigsaw, and allowing for them, and trying to guess what they look like.

With quantum theory, some (such as Eugene Wigner) say that consciousness is involved in the answer at some deep level. Personally, I think not, but it's an open question.

You seem to think that idea and cause and effect can't both be true, and you put cause and effect with block time. But block time removes cause and effect, or threatens to, because without motion through time, and a sequence of events with one event preceding another, it's hard to see how cause and effect can happen.

That's what I've argued, and I think cause and effect is unavoidable - it happens without the intervention of human consciousness. The landscape of this planet was being shaped by natural forces a long time before humans evolved here. And when they did, all of their science was based on cause and effect.

But consciousness is still real, it just doesn't act instead of cause and effect. That's how I see it anyway, hope this makes sense...

Best wishes, Jonathan

    PS. You seem to think the question of whether or not the future exists depends on whether it is predictable. But it isn't about that (and even a predictable future doesn't necessarily have to exist yet).

    It's about whether the future actually exists already for other reasons. In block time, it exists already because all of time is already laid out, like a dimension. I've tried to show by reasoning that this can't be the case.

      Hi Jonathan, thanks for replying. I don't articulate very well, I apologize. I was actually trying to concern myself with the problem you define, which is block time vs. time in motion (meaning infinite possibilities). As I understand the theory of relativity, speed affects the passage of time, thus I could travel to and fro from past to future assuming that was physically possible. This suggest block time, that there is a set past that can't be changed, but theoretically could be changed if I went back and killed myself. That seems to be a paradox of block time, that all things are set and knowable. It seems block time paradox assumes only cause and effect without allowing for the possibility of conscious as a separate intervening element (because conscious allows for infinite possibilities, parallel universes etc).

      It seems to me that motion through time allows for the possibility of conscious as a separate element, unlimited possibilities that can't be "pre-ordained" with block time.

      I am very interested in your issue and would like to make sure I fully understand.

      Hello Chris,

      you have it right where you say that in relativity speed affects the passage of time. Where you mention time travel, I'd say don't think about that for now, it's confusing everywhere you find it, from physics to hollywood. And we don't know if going back in time is possible. Also leave many possibilites to one side, and many universes, which are also confusing ways of looking at things, and they're not backed up by experiment.

      What we do know, from experiments, is that motion through time has its rate affected by objects moving through space, as you say. The trouble is, the same theory that tells us that, in the way we interpret it at present, also produces a picture of the universe frozen up, called block time, with all of time and history already laid out like a dimension. And that picture seems to tell us that this motion through time (that varies its speed) can't be real.

      But we observe this apprent motion every day, or seem to. There's a sequence to events somehow. No-one has found a good explanation for this apparent motion through time, but the standard view, in as far as there is one, is that it doesn't exist, and that it must be some kind of illusion. But physicsts don't normally look closely at the possibility that it's an illusion (it seems to go outside our field), so instead that idea often gets swept under the carpet. In my essay, I've looked at this idea of an illusion, and found that it doesn't work easily at all.

      I've argued that only one of the two pictures of time we know of can be real, the frozen universe, and the moving through time universe. Thinking about possible future events, one of these pictures means we're contributing to shaping what happens, as we seem to be. That's the one with motion through time. In the frozen universe of block time, we're not, because all events in history are already set in place, and they already exist.

      But there's a lot of evidence for cause and effect, and motion through time. The block time picture goes against an enormous amount of evidence and obsevation, and if only one of the two pictures of time can be true, as I've tried to show, then block time would remove the laws of physics, and really the foundations of science. That's a high price to pay, just to have our present interpretation of relativity exactly right. I've argued that it might be slightly wrong, and that this would remove the problem. It would also mean that we can be affecting events, as we seem to be.

      Best wishes, Jonathan

      Jonathan,

      You wrote: "We may have been held back by too often assuming that Minkowski's assumptions about the time dimension are inseparable from SR. But a theory can be absolutely right without its interpretation being right, and only the core of SR has been confirmed by experiment."

      Has it? The core of special relativity is shielded by what Lakatos calls "protective belt":

      http://bertie.ccsu.edu/naturesci/PhilSci/Lakatos.html

      "Lakatos distinguished between two parts of a scientific theory: its "hard core" which contains its basic assumptions (or axioms, when set out formally and explicitly), and its "protective belt", a surrounding defensive set of "ad hoc" (produced for the occasion) hypotheses. (...) In Lakatos' model, we have to explicitly take into account the "ad hoc hypotheses" which serve as the protective belt. The protective belt serves to deflect "refuting" propositions from the core assumptions..."

      Without the protective belt ("contracting lengths, local time, or Lorentz transformations") the Michelson-Morley experiment would have unequivocally confirmed the emission theory's tenet that the speed of light varies with the speed of the light source (c'=c+v) and refuted the assumption that the speed of light is independent of the speed of the light source (c'=c):

      http://www.amazon.com/Relativity-Its-Roots-Banesh-Hoffmann/dp/0486406768

      "Relativity and Its Roots" By Banesh Hoffmann: "Moreover, if light consists of particles, as Einstein had suggested in his paper submitted just thirteen weeks before this one, the second principle seems absurd: A stone thrown from a speeding train can do far more damage than one thrown from a train at rest; the speed of the particle is not independent of the motion of the object emitting it. And if we take light to consist of particles and assume that these particles obey Newton's laws, they will conform to Newtonian relativity and thus automatically account for the null result of the Michelson-Morley experiment without recourse to contracting lengths, local time, or Lorentz transformations. Yet, as we have seen, Einstein resisted the temptation to account for the null result in terms of particles of light and simple, familiar Newtonian ideas, and introduced as his second postulate something that was more or less obvious when thought of in terms of waves in an ether."

      Hello again Pentcho,

      it can be a matter of taste what constitutes the core of a theory, but it is comparatively clear what has been confirmed by experiment. In SR a key part of the core is the time dilation equation, from the Lorentz-Einstein transformations. This has been confirmed many times, a good example being the experiment with muons at CERN in 1976, in which travelling near to c led to the fixed lifetimes of the muons being multiplied by around 29.3.

      This looks like time itself being affected, because the lifetime of the muon in its restframe had been measured accurately before then. And as Einstein arrived at time dilation from a fixed speed of light (which was also implied in Maxwell's equations), this looks very much like confirmation for that whole part of SR. There are many other experiments, see

      http://math.ucr.edu/home/baez/physics/Relativity/SR/experiments.html

      and for tests of light speed from moving sources

      http://math.ucr.edu/home/baez/physics/Relativity/SR/experiments.html#moving-source_tests

      I always hope people will admit the clues we have and get on with solving the puzzle, instead of trying to deny them, get around them, or just to ignore them. Even clues that look very weird can turn out not be quite so weird once the puzzle is solved, as past experience has shown.

      The constant speed of light in relation to motion time dilation seems definite to me, but in relation to gravity it's not so certain. Einstein suggested a variable speed of light in a gravity field well after SR, in 1911, during a transitional phase when he was trying to splice SR with gravity. And others have done the same - experimental results in relation to a constant speed of light within a gravity field are more ambiguous.

      But returning to what you mentioned in your post, it's very clear that spacetime hasn't been confirmed, but that the core, or some of the core, of SR has. The spacetime interpretation of SR is untestable, incomplete at best, and a cul-de-sac that has caused a century of confusion at worst.

      Best wishes, Jonathan

        Jonathan,

        You wrote: "This looks like time itself being affected, because the lifetime of the muon in its restframe had been measured accurately before then."

        If you knew how the lifetime of muons "at rest" is measured, you wouldn't be so sure:

        http://cosmic.lbl.gov/more/SeanFottrell.pdf

        "Experiment 1: The lifetime of muons at rest (...) Some of these muons are stopped within the plastic of the detector and the electronics are designed to measure the time between their arrival and their subsequent decay. The amount of time that a muon existed before it reached the detector had no effect on how long it continued to live once it entered the detector. Therefore, the decay times measured by the detector gave an accurate value of the muon's lifetime. After two kinds of noise were subtracted from the data, the results from three data sets yielded an average lifetime of 2.07x 10^(-6)s, in good agreement with the accepted value of 2.20x 10^(-6)s."

        That is, muons bump into the plastic of the detector and their speed suddenly changes from almost 300000km/s to zero. Could such a violent collision cause rapid subsequent disintegration? Or non-colliding muons gloriously live longer because they suffer time dilation, as Divine Albert's Divine Theory has predicted?

        http://www.physics.rutgers.edu/ugrad/389/muon/muon-rutgers.pdf

        "In order to measure the decay constant for a muon at rest (or the corresponding mean-life) one must stop and detect a muon, wait for and detect its decay products, and measure the time interval between capture and decay. Since muons decaying at rest are selected, it is the proper lifetime that is measured. Lifetimes of muons in flight are time-dilated (velocity dependent), and can be much longer..."

        A similar wisdom:

        In order to measure the lifetime of a driver at rest, one must observe a car coming to a sudden stop into a wall. Lifetimes of moving drivers can be much longer...

        Pentcho Valev pvalev@yahoo.com

        This page has links to several hundred experiments that have confirmed the core of special relativity:

        http://math.ucr.edu/home/baez/physics/Relativity/SR/experiments.html

        I'm not going to discuss them all with you for many reasons, including some that have exclamation marks. One reason is that I don't know if even that would convince you of what we know clearly from experiment. Some people don't want the clues, they don't want to know what's out there. Instead they want to fit some other idea to the world at any cost.

        Being right doesn't make Einstein divine, a lot of people are right about a lot of things. And a lot of people are wrong about a lot of things, and they frequently include people who deny SR. As you can see from my essay, I'm not one to follow blindly - I've questioned many things relating to SR, including Minkowski's work, which Einstein took onboard, and believed. He's not a sacred cow to me, and I think he was wrong about some things. But look at that page with the experiments, you look through them. It just is like that - we don't know why, but it is.

        Best wishes, Jonathan

          Jonathan, as a history major, I note this about your ideas, which may or may not be true. I only offer this because it is something that jumped out to me. I know that "bias" is an important part of ascertaining the truth, and that bias plays an important role in scientific experimentation. Thus, I offer the suggestion that you disagreement with the "illusions" of block time may be rooted in a cultural bias we in the West have, which is a "linear view" of history.

          The "block time" you described, that there is no future, may or may not be new to modern science, but has roots in many old philosophies, sciences, beliefs, such as Taoism. This isn't suprising, as cultures of old had a "cyclical view of history." That view of history no longer exist in the West, and now a "linear" view of history exists, and permeates our religions and I would argue our sciences.

          At its core, under a linear view of history, history doesn't repeat, its not knowable, for it is unknown. Man determines his own destiny. This move to a linear view of history was driven in large part by technology, through which man believes he can create a new future, his own destiny. Is it any surprise the, that Quantum dillemmas, very dependent on technology to measure the smallest of scales, sees an open unknowable future? There is probably no better statement showing a "linear view" bias than this: So quantum theory shows us an unfixed world, which potentially "allows us to be affecting events around us, and altering the future, as we seem to be."

          In your introduction, you begin by phrasing the problem of time as first being a conceptual problem. I agree. There is a "conceptual" problem of time easily explained in cultural biases of their time. Does this mean your is wrong? No. But I raise this issue only for you to consider, in case you haven't.

          "The nature of time may well include elements outside our present ideas, that we haven't yet found." This statement shows a present bias. By definition, it limits from consideration ideas from other philosophies, written, recorded, and still practiced by some.

          You go on to write "A century later we know a lot more about the physical world, but we still don't understand time." You recognize the limitation of modern experimentation, and even quantum theory as a theory, but refuse to accept "concepts" of time, that time in fact doesn't exist, and thus there is no past, present or future.

          I don't share some of your conceptual problems with block time. For example, you write "It's hard to argue that the future already exists at larger scales, but not at smaller scales. Any causal connection across scales would make that impossible, and (rather like the butterfly effect), a little would go a long way." First, this again is a "linear" view of history/time. It assumes that the future is not certain because we cannot see it. The fact that modern technology allows us to see things at a small scale does not change, however, the concepts of time. You believe it does. You believe that because we can see and measure things so small, and because those things appear to have motion in the third dimension, that both time exist and motion is time exist. As you begin your essay, time is conceptual, and technology has not changed that. It has not dispelled any illusions, but possibly created others.

          However, conceptually, the breaking down on objects on an "everyday scale" doesn't create a conceptual problem with "block time." An explanation is again a cartoon. Quantum theorist look at an individual frame, with the inability to see the next frame, and try to predict what that next frame will be, but they can't with certainty, bc they can't see it, they only guess at what it might be with probabilities. Fourth dimensionally, however that entire cartoon exists. Thus "time" is the illusion created by looking at a part and not the whole.

          Hello. Not sure if it's Chris or someone else, welcome anyway.

          There are so many things you haven't understood in your post that it's hard to know where to start. You seem not to understand the physics at all, which would fit with... your having studied history, not physics. So let's talk about history first, at least you'll understand me. I agree that a linear view of history is sometimes a very bad idea. It implies a progression, and that can involve a bias towards various economic views of the world that may not be good for people psychologically. (Some economic systems, for instance, require growth constantly, and that can be unsustainable, which can eventually be bad for the planet and people in a number of ways.) And in a more general way, change for its own sake is not always good.

          Then there's what I was saying about physics, which is nothing to do with that, or anything you mention in your post. Every single bit you mention, more or less without exception, you have misunderstood, so it might be better if we just leave it, but I'll try a little.

          When I say 'the nature of time', I'm not talking about cultural ideas. I'm talking about the actual physics of time. I'm going to talk about what happens in one room, because otherwise you might start relating it to human history and culture again. If I move my hand past my face at 6 km per hour (about walking speed), I'm seeing it in slightly slow motion. it has been slowed down by a factor very close to 1, 0.9999999999999999845, so very slightly. This isn't noticeable, but we measure it accurately in laboratories.

          Nobody knows why - we're trying to find out. We have a lot of clues, and the essay you read is about looking at them, and trying to work out what's going on. One of them is that the present interpretation of special relativity suggests motion through time doesn't exist. But no-one has been able to explain why we still seem to observe a sequence of events every day. In the one room I'm talking about (so you won't start relating this to history again), events appear to happen in an order - one event follows another. This allows cause and effct to happen, and the person in the room seems to be able to affect events. If she puts the kettle on, she can make a cup of coffee, and so on. No-one knows why we appear to experience a flow of time, or if you like, a sequence of events. But the standard view, in as far as there is one, is that it is an illusion. But no-one can explain how such an illusion might work.

          Where I say time is a conceptual problem, I mean within the physics. I mean that it's not a mathematical problem initially, it's on the conceptual side - that is, it's a problem with the interpretation, ie. the conceptual picture we use, that is, Minkowski spacetime.

          When I say "It's hard to argue that the future already exists at larger scales, but not at smaller scales", I'm talking about a specific problem in physics that you haven't understood, about the difficulty we have relating what happens at a small scale and what happens at a large scale. Each is described by a different theory, and we have trouble making ends meet.

          And it goes on, there were several other points you hadn't understood.

          Looking at this sentence "The "block time" you described, that there is no future, may or may not be new to modern science, but has roots in many old philosophies, sciences, beliefs, such as Taoism.", this has more than one error in it. Block time says the future already exists, not that there is no future. You can't start relating it to other ideas until you understand it, and even then it's not backed up by experiment, so it's not a good idea to do that. And it doesn't 'have roots' in those ideas. If you must grab things and loosely relate them to other ideas (which you do quite a few times in your post), then at least do that with solid physics that has been confirmed by experiment - there's plenty to choose from.

          I hope this helps to make a little sense of it. Physics isn't a loose discipline where you can loosely throw one idea at another and say they go together. If you're interested, I suggest you start looking at physics from the beginning - this isn't the right place to start. Or read more about the cultural side of time, which has plenty of literature about it, and which seems to be your area of interest.

          Best wishes, Jonathan

          You don't want to discuss fraudulent experimental evidence, Jonathan? Why not? Let me refer you to perhaps the greatest fraud:

          http://adsabs.harvard.edu/abs/2010AAS...21530404H

          Open Questions Regarding the 1925 Measurement of the Gravitational Redshift of Sirius B, Jay B. Holberg Univ. of Arizona: "In January 1924 Arthur Eddington wrote to Walter S. Adams at the Mt. Wilson Observatory suggesting a measurement of the "Einstein shift" in Sirius B and providing an estimate of its magnitude. Adams' 1925 published results agreed remarkably well with Eddington's estimate. Initially this achievement was hailed as the third empirical test of General Relativity (after Mercury's anomalous perihelion advance and the 1919 measurement of the deflection of starlight). IT HAS BEEN KNOWN FOR SOME TIME THAT BOTH EDDINGTON'S ESTIMATE AND ADAMS' MEASUREMENT UNDERESTIMATED THE TRUE SIRIUS B GRAVITATIONAL REDSHIFT BY A FACTOR OF FOUR."

          http://irfu.cea.fr/Phocea/file.php?file=Ast/2774/RELATIVITE-052-456.pdf

          Jean-Marc Bonnet Bidaud: "C'est ce qu'aurait dû trouver Adams sur ses plaques s'il n'avait pas été "influencé" par le calcul erroné d'Eddington. L'écart est tellement flagrant que la suspicion de fraude a bien été envisagée."

          http://www.gravityresearchfoundation.org/pdf/awarded/1979/hetherington.pdf

          "...Eddington asked Adams to attempt the measurement. (...) ...Adams reported an average differential redshift of nineteen kilometers per second, very nearly the predicted gravitational redshift. Eddington was delighted with the result... (...) In 1928 Joseph Moore at the Lick Observatory measured differences between the redshifts of Sirius and Sirius B... (...) ...the average was nineteen kilometers per second, precisely what Adams had reported. (...) More seriously damaging to the reputation of Adams and Moore is the measurement in the 1960s at Mount Wilson by Jesse Greenstein, J.Oke, and H.Shipman. They found a differential redshift for Sirius B of roughly eighty kilometers per second."

          Hello Pentcho,

          In most areas of science people are simply trying to find out the truth. But there are a few areas where sadly people have a bias about what they hope to find.

          In those areas, to put it mildly, you can't believe all you read on the internet. Relativity is one of them. In areas such as that there are people trying to show the standard view to be wrong, for reasons other than scientific ones. Yes, in the case of relativity there's bias in both directions, so you have to check everything carefully, but the people trying to deny SR are sometimes cleverly distorting the facts.

          I think you have been taken in by these websites you read, and they can't be trusted. Whether or not Eddington got a measurement wrong, we know the restframe lifetime of the muon. Modern measurements are where you should look, and there was one made at NIST in 2010, in which they measured the time dilation of a moving object, at a speed of only around 10 m/sec. There have been other experiments recently which confirm SR very accurately, and our conversation is going to be unscientific if you don't look at them. Try this one:

          Chou, C. W. et al, Optical clocks and Relativity, Science 24 Sept 2010: Vol. 329 no. 5999 pp. 1630-1633

          In fact, I suspect it might not really be a discussion of physics even if you do look at the evidence. But I'd like to warn you about these websites you read, and help you to be more aware of the pitfalls in the landscape. Physics is very hard even if you get all the clues in front of you. If you don't, it's impossible. So you must work hard to get at the real clues, check everything you can, then you can try to solve these puzzles with some chance of success.

          The only other thing to say is that as you know, I believe SR to be right but the spacetime interpretation to be wrong. This can explain some of the confusion about SR, but not all of it. Some people are against the physics establishment because of what it represents to them, rather than for better reasons.

          Good luck, Jonathan

            Jonathan,

            You wrote: "I believe SR to be right but the spacetime interpretation to be wrong."

            That's all I need to know, Jonathan. Thank you for the discussion.

            Pentcho Valev pvalev@yahoo.com

            Yes, there are many who take both to be right, and quite a few who take both to be wrong. But if in fact neither of these approaches is accurate, and instead the theory is right but the accompanying picture is wrong, then an interesting new landscape appears, which is comparatively unexplored. It may hold answers that haven't yet been found. Thanks for the discussion,

            best wishes, Jonathan

              Just a suggestion: Sooner or later you will have to answer the question:

              Can Minkowski spacetime be presented as a deductive consequence of Einstein's 1905 two postulates?

              If the answer is yes, you will have to question the postulates - the combination "true premises, false conclusion" is forbidden by definition. If the answer is no...

              Best regards, Pentcho

              Of course Minkowski spacetime is not a deductive consequence of any part of SR. A good relativist would never claim that it is, but people often imply it. It's just that spacetime looks like it might well be true, and if you make time a dimension as similar to the other dimensions as possible (and it still isn't very similar), then you get what looks like a few things clicking into place. And what comes out works very well mathematically, and allowed us to simplify many theories.

              But there are probably humdreds of other possible interpretations of SR out there, well - ones that look possible initially. But when you pursue them, you might find contradictions come out around sixty years later, as we did with spacetime.

              As I said, physics is full of equivalence. Often more than one conceptual picture can be described by the same mathematics. The mathematics of SR is like Pythagoras' theorem - three speeds are in the same relationship as the three sides of a right angle triangle. No-one knows why.

                John Norton: "That the speed of light is a constant is one of the most important facts about space and time in special relativity. That fact gets expressed geometrically in spacetime geometry through the existence of light cones, or, as it is sometimes said, the "light cone structure" of spacetime. (...) So if we mean a spacetime that also behaves the way special relativity demands, then we have a Minkowski spacetime."
