Lee Smolin Public Lecture Special: Einstein’s Unfinished Revolution

Ғылым және технология

On April 17, in a special webcast talk based on his latest book, Einstein’s Unfinished Revolution, Perimeter’s Lee Smolin argued that the problems that have bedeviled quantum physics since its inception are unsolved and unsolvable for the simple reason that the theory is incomplete. There is more to quantum physics waiting to be discovered.

    Hats Off to Lee Smolin for how he answered the young boys questions @1:04:27 rather than brushing the questions he answers it in a way that both answers the questions (to the extent that he can) and then encourage the boy to progress further. That is the job of a teacher and an elder. . A thousand bows to you Sir !

    @@nmarbletoe8210 Not sure. Smolin points out that whenever anything weird goes unexplained for too long then we usually require a new hypothesis. Scientists knew there was something wrong with Newtonian mechanics when the strange orbit of Mercury could not be properly explained (was solved by Einstein and General Relativity). Quantum mechanics was developed by Planck to explain observational problems associated with EM-theory. Some scientists are now saying that dark-matter and dark-energy might not exist (these fictions were hypothesized 20-years ago to explain observational oddities in astronomy but 20-years of looking for either one has come up blank) so just as Einstein's theory modifies Newtonian mechanics for the special cases involving extreme gravity, some scientists think the observational astronomy problems might be better fixed by new special-case modifications to relativity. Now let's get back to your point: Anyone can dream up anything but thoughts are worthless if they cannot be proven experimentally (they have to pass the scientific method). Lots of time was wasted on Super-symmetry but that now appears to be dead because no super-symmetric particles have been detected anywhere at anytime including the last round at the LHC. And what of string theory? I have been told that S-T properly describes approximately 20% of the real world so what's up with the other 80% and how do you choose? While S-T has been successful in providing jobs to people who teach it, lack of experimental verification proves it is only slightly more useful than palm-reading. Now if the "many worlds interpretation" of quantum mechanics is supposed to be an improvement over the "Copenhagen interpretation" then I suppose that is in the eye of the beholder. IMHO when scientists tell the public at large that we might be living in a multiverse, I worry that people without scientific training will turn to the occult.

He only came back to Portugal after Salazar's death and he brought with him De Broglie's ideas about Physics. These have been under development by a small group of «unorthodox-rebel» researchers (who, in turn, were students of Andrade e Silva), the main culprit being Prof. José Croca, who has published extensively on these matters.

    Time is a human construct. Where I think we should put all our efforts now is just HOW this Universe is constructed, not WHAT the outward appearances of it are. Imagine that the Gods could go through time at any speed and any direction. This solves the non-locality right off. Like, how does two hydrogen react with an oxygen to form water? Is there some kind of emanation coming off of the oxygen which, in effect, says "I'm looking to bond now." And the hydrogen says, "I'm looking to bond also, according to my valence shell." And then they somehow get together in some arrangement. If these valence emanations happened in no-time, and only in the realm of human time do we witness a molecule of water, then this could be one possible explanation of why chemistry works. Again, we must see WHAT happens, as CERN has done, it is now our prime directive in physics to model HOW this Universe does it. Pull out all the stops! We are living in a simulation!

    The Zen Koan about a tree falling in the forest was generated centuries ago as a means to exhaust the excursions of linear mind. Once a physicist realized that sound was actually energy waves being propagated thru air or any other medium, the question if the falling tree made a sound became absurd. Of course it made a sound, whether there was a detector present (human ear or mechanical or electronic) or not. Quantum mechanics, as currently propagated, represents an incredibly useful and in many ways a phenomenally accurate understanding of the universe of the very small. Like the question of sound in the absence of a human detector, the current QM model is also obviously INCOMPLETE. Once a physicist of adequate insight is able to add to the QM model, in the same way that Einstein added one additional term to expand Newton's equations, the need to include an observer in the QM model will disappear. Thank you Lee Smolin and Roger Penrose for standing for the probability that once a more complete model of QM is propagated, the widespread inability to understand QM, will in part disappear.

For the most part he speaks absolutely smoothly and fluently and you can see where he does pause before he speaks, it is not because he does not understand a question or the answer to it, he is stopping to consider what is the best way to convey this information in the shortest amount of time so that anyone listening will get a full grasp not just of the words coming out of his mouth, but the content of what he is trying to say.

    Smolin makes a *very good* point here: quantum theory was *constructed* to be only about observables and not about beables. The fact that we can't find beables in it does not mean there aren't any. It was deliberately crafted to "operate" at the level of observation. Quantum systems do have quantum states, but these states are just not "like," say, the electric and magnetic fields, which have tangible existence at every point in space. Quantum states live in rather abstract Hilbert spaces, and in order to get a connection to the world you have to do math on them and that math, by design, yields *probabilities*. An unobserved quantum state will evolve in a deterministic way, but the change of state that results from an observation is *not* specified by the starting state at all - essentially it's put in by hand. None of this is meant as a criticism of quantum theory. It does exactly what it was designed to do, and as far as we can tell it does it *perfectly*. But as Smolin points out here, it just wasn't intended to "describe the world." It was intended to describe our "witnessing" of the world. Totally different thing.

    The question of why the speed of light is a constant the young person asked is one I've contemplated myself. I believe it to be from a force of resistance that is dark energy, but the strong nuclear force could be the same thing. This lecture was such a breath of fresh air and absolute unflinching honesty. He very clearly defined the early Bohr models with an accurate opinion, and I was happy to see De Broglie put in the proper light he deserves. Now we need someone to reassess the EM model in relation to Gravity and we may find the real quantum laws and that gravity doesn't fit the model because it doesn't exist if there is entanglement and non-locality.

    I think the key point with entanglement is that it is the effect of a measurement which causes an instantaneous effect to occur at the entangled particle. The entangled system is prepared and we can think of a single system comprising two particles (looped waves) which is extended in space and this single system is completely affected by a measurement. So we still cannot transmit a wave at faster than the speed of light but when we measure an entangled system it collapses at faster than the speed of light. This is a property of spacetime that we have to accept and it does not contradict SR or GR. Richard

    Mr. Murugesan, the 'realism' intrinsically inherent in QM is that it is a probabilistic crap shoot, and no material scientist alive can say otherwise. We cannot impose a theory of 'realism'' on the quantum level of existence when it is, by definition, probabilistic to say the best, even when entanglement is a predictable phenomena, along with wave collapse. 'Realism' is a mode of thought intrinsic to humans at the macro level, when it has been incontrovertibly proven that this 'realism' does NOT exist at the quantum level. If anything cannot be more blatantly denied, it is this dual nature of the quantum, which was originally expressed by Bohr in the Copenhagen. So. . . .for 100 years now, as the GPS satellites roam about the stratosphere, and all the other numerous commodifications of QM are benefitting millions upon millions, the reactionary 'realists' (and that included even Albert Einstein) are still complaining that, they cannot put their fingers on something that will stop wiggling and stand still. WHAT. . . .will they think of next?????

You are claiming the wave and photon in either case arrive there, but we don't see it because we are bound by space time. Who ever said that? It's not there immediately it's measured in discrete packets that act like waves or waves that act like packets or both. It's not instantly seen, if it was then we'd never know when something happened, because all things would be happening and we'd see them at once. The speed of light doesn't just exist in our mind. It exists in the universe. Hence when a thing happens here, 60 million light years away it's effect is not seen nor felt, until the wave or photon hits that location. You can claim that time changes, or time scales of our viewpoint can alter it. That's not the same as saying it's instant.

    Its called de Broglie-Bohm theory, or more popularly Bohmian Mechanics. All of the experimental predictions are equivalent to standard QM, i.e. the two theories are scientifically indistinguishable. However, from the point of view foundational principles, Bohmian Mechanics is completely opposite to the Copenhagen interpretation of standard QM. As mathematical constructions, the theory of standard QM seems to be a somewhat superficial sectioning off of the theory of Bohmian Mechanics, where the rest of the mathematical structures present in Bohmian Mechanics are simply ignored as non-existent. It is in the above 'theory-as-a-mathematical-construction' sense that Bohmian Mechanics is the completion of standard QM, making standard QM simply wrong as a fundamental theory because it is literally incomplete.

    When he spoke of entanglement of A & B, he said B would be affected by what was "measured" at A and this was "mirrored" at a point of origin. Does this point of origin have any description in the theory? The distance between the two particles could vary so would the point of origin have a determinable value?

    As far as I understand, when prof. Smolin says "QM is wrong" he means "QM is incompatible with realism". So he does not mean that it fails to explain experimental data, but that it seems inconsistent when you look at it from a certain point of view! So why not claim that this point of view (I mean "realism") is wrong? For example: if you consider the Schroedinger cat paradox from the realist's point of view it doesn't make sense. If you consider it from the "anti-realist" point view it makes sense. The same with the entanglement. I see NO justification for "realism" in the context of QM. We should consider conjecture: "QM is correct, realism is incorrect."

    Scientific realism is a foundation stone of physics that Dr. Albert Einstein and Erwin Schroedinger and many other physicists fought very hard to keep. It's the philosophical heart of the entire physics enterprise. See, for example, the writing of David Hestenes on scientific realism in his book "New Foundations for Classical Mechanics, Ch: 9 Foundations of Mechanics. I consider this Dr. Smolin's "coming out" by announcing in no uncertain terms that he is not sitting on the fence anymore about the claim that Quantum Mechanics is complete. He might be playing devil's advocate for his book on Einstein's unfinished revolution, but even if he and Einstein are wrong, "ruins may still be good for something". Stating that QM is incomplete just after the release of the M87 black hole photo is actually excellent timing! The point isn't that entanglement doesn't exist, but that if it does, and this seems to be the case, QM and the Copenhagen interpretation refuses to say anything about, and forbids further inquiry into, a nonlocal physical effect that seemingly takes place at a speed much greater than light. It's like proving the existence of atoms at low energies from the Brownian motion of pollen. If you can find a physical mechanism such as a Kerr-Newman electron or Einstein-Rosen bridge that explains entanglement, the Copenhagen interpretation is shown to be wrong and Quantum Mechanics is proven incomplete. E..T. Jaynes has 3 unpublished papers in which he made similar remarks about Quantum Mechanics and the Copenhagen Interpretation ("Clearing Up Mysteries: The original goal", "Scattering of Light by Free Electrons", and "Quantum Theory and Probability").

    ​@@BlueGiant69202 Thank you for your reply. I think that what people call "realism" (but it may have different meanings) is a point of view that is not a defensible standpoint not only in QM, but in other areas of physics, science etc. It usually requires additional assumptions, just for the sake of having "nicer" picture. Dirac (anti-realist) wrote in his QM textbook, that Physics is not to provide pictures, but to predict outcomes of experiments. If you start thinking like a realist, you immediately find yourself in trouble, trying to understand e.g. that "particle can go through two slits at the same time and interfere with itself". If you are an anti-relist you would say: "term such as position or trajectory does not have any meaning until we come up with an experimental procedure to define them (=measure them)". Here Heisenberg would say that Physics should deal only with observable (measurable) quantities, because only for observable quantities we can find a correspondence between the terms we are using (e.g. position) and things that we observe. It is simple as that. I do not mean that radical metaphysical "anti-realists" are correct. They say "reality does not exist" and I do not think this is a true statement (whatever that means). But I think (so called) scientific instrumentalists (which as far as I understand prof. Smolin calls "anti-realists") are perfectly correct by saying that our concepts (like velocity, trajectory, position, particle, field etc.) are just terms that we use to describe observable phenomena, and assuming that there must (!) be something out there in reality corresponding to these terms (because our theory work) is an unjustified extrapolation in my opinion. I completely disagree with your statements: "Scientific realism is a foundation stone of physics (..)" and " It's the philosophical heart of the entire physics enterprise." It is not! I would say that this is the most harmful point of view in the context of QM, because it pushes many people onto a path of finding some classical pictures for QM. And the only result is more and more confusion and statements like "cat is dead and alive at the same time" which are completely wrong. They are made even by people who would call themselves supporters of Copenhagen Interpretation, but who are not really able to abandon this classical, "realistic" way of looking at physics. Realism should be cut off as a dead wood from Physics once and for all. And it will not stop the progress of science, but boost it. Founders of QM (especially Heisenberg) where really much wiser than you'd expect. Just a little remark at the end. I am probably wrong...

    @@RupecPupec This is not really a response to sebastian dawid. This is just a quick comment and thought which I should have probably posted elsewhere. I watched this once and thought I knew what Smolin was saying. Not I'm not quite as sure. It seems he hates the idea of entanglement as being real. He doesn't like the fact that "wave like" properties cannot be deterministically measured. So he feels all FATE of the universe should be predicted from a fixed timeset of our reality. He defines realism it seems to me as being a kind of Newtonian understanding of what is going on even in QM and if we can't measure it that way, we must be wrong and not realistic. He seems to me to be saying entanglement must be wrong but it's out there, we need to look at this again and do away with it. Because it validates our finite state understanding. At least this is what I thought he said. From an earlier watching of what he seemed to say. Now I'm not even sure of that. I'm wondering if he's claiming entanglement facts of entangled particles didn't even work and were not even proved. Or if he's stating we have to observe to entangled pairs from two locations to understand all their properties, because of the nature of what we can measure. And he's hurt because that is the current state, but it works, ironically. It just doesn't work enough to please his wish for "keeping it real" - my term of what it seems he feels the argument would be. So if I could define all things without waves which seem to randomly move about and make them particles with newtonian precision, that would finally make him happy? If I could measure all states from any point for a particle and get rid of duality that would make him happy? Is this what he's referring to. I actually thought I knew what he was saying the first time I watched it, and perhaps I made false assumptions. Now I'm even more confused after watching it again. He wants cats to be alive or dead before the box is open? He doesn't like quantum entanglement which has been measured? Or he fails to agree the measurement even works? He thinks it's all lost in statistics. This just does not make sense. It seems he argues that locality from two spots to determine both aspects of a particle property is a bad thing and it means we cannot know all about the particle so it shows we can never be considered using a real technique. He's wishing for a different technique, but none exist? How would we find that? Wow. I've got to see more videos to see if this fits into a pattern of if this is just some kind of Calvinistic kind of deterministic wish or something where he says, I'm not going to be able to see an know everything about the universe with this theory, so it's gotta be bad. It's very confusing but I don't have the time to figure it out tonight. I have other things to do. I actually thought this was kind of brilliant the first time I watched it. It really got me thinking. Unfortunately when I revisited it the second time, I'm thinking this is nothing more than a definition of wanting Rule 1 to only exist and do away with Rule 2 altogether. I thought he was complaining about RULE 1 and wanting to kill it or constrain it with RULE 2, but now it looks the other way around. To me "realism" at this point of time must accept both. If you break one of the two you're breaking physics. I may be thinking of a different video so I'll have to watch more when I think about the "problem of physics" I kind of feel physics is broke, but not in the way this is being told now. I used to think it's a good reason and starting point, but now I'm going to have to revisit my own little "short pet theory" and happy thought, because I see physics as being broken a different way. And I don't think this is the way it is. And since I'm a real novice actually my little "pet thoughts" mean nothing until much smarter people than I can show a way to prove or disprove them. With a large body of evidence proving the two rules the burden of proof is on the doubters, not the current approach. I could put my understanding differently than this guy, but I'm not willing to post it out here yet. I just know that to me this is a very weak argument now to me and I don't think I can use this as any kind of "proof" or "doubt" reason to say I may have a better way to do things. He at times even says things that seem like he's jumping the fence back and forth. What does he want and expect and how could we get there. I'm left with a feeling that he's just feeling troubled. I hope I can find the error in my thoughts on this. I hoped this would give me some flaw that would perhaps help my own pet theory, this apparently does not.

I am only a lay person with very basic understanding of this subject, but have always felt uncomfortable with the mainstream theory that involves probability functions, and particles that drop into a particular state when observed. As he answered at the end just because a theory has workable results doesn't mean it completely/actually reflects reality. Just look at Einstein's theory of gravity. I'm sure a theory will come along like Relativity that builds elements of our current understanding and expands on QM. Lee's description sums up how I have felt about this subject, and I will certainly give the book a read. Always enjoyed Lee's talks along with Frank Wilzcek, and Lawrence Krauss.

    Many questions to Dr Smolin. Caroline Thompson was able to reinterpret the 'Bell inequality' experiments , and showed that one cannot conclude much from these experiments. Do you agree with her? So if we have to create new QM rules that generalises this field of physics, is De Broglie's dual solution the best option? De Broglie returned to his initial idea about wave-mechanics at the end of his career, but nobody seems to notice except for a few physicists like Antonie Valentini (Perimeter institute). For instance, this approach allows for abolishing Born's rule of QM, according to Valentini's theory/papers. But if we accept the reality of De Broglie's pilot waves, what is the electrodynamic nature of these waves? Haven't we forgotten to fix and generalise Classical Electrodynamics first, before we can move on to 'quantum realism'? Is for instance the CED gauge "principle" valid? A new experimental fact about CED is that the Coulomb field propagation speed is much higher than 'c', and this falsifies the gauge principle (which is a principle also required for being able to "renormalise" QED values, but the "super precise" QED predictions have been proven to be a big fraud anyway). Are you aware of the fact that QED theory has more or less be 'debunked' by Oliver Consa? Could this be a sign of pathological theoretical developments based on incorrect physics principles? Are you aware of the fact that Dayton Miller proved experimentally that the speed of light is variable? And that Einstein (together with Shankland) mismanaged Dayton's dataset (it disappeared) and that the so called 'temperature variation artefact' with respect to Dayton's experiments was a big lie by Einstein, because Dayton Miller had done tests if temperature variations had an effect on his measurements, and it didn't. Isn't it time, Dr. Smolin, to choose new role models, in stead of having these role model physicists in mind, that had physics theory locked up in a mental prison? I know it is Dr Smolin's greatest desire to step outside the prison, however, questions, questions, questions. The way Lee Smolin answered the question of the kid was very sympathetic and serieus, and it was a very good answer, kudos Dr Smolin.

    The point where Smolin ends his historical review of quantum theory is precisely where robust alternatives to the anti-realist Copenhagen interpretation emerged. Among the realists listed (but only briefly discussed) in Smolin's last slide were Louis de Brolie and David Bohm. These were the pioneers of the pilot wave interpretation, which explicitly resolves the quantum measurement problem (formulated as Rule 1 and Rule 2 @28:28). In pilot wave theory, Rule 1 is expressed as the quantum wave function, which it shares in common with the Copenhagan interpretaion. Rule 2 is summarised as Born's Law, which pilot wave theory shares with Copenhagen, but with the following difference: In pilot wave theory, there is no discontinuous collapse of the wave function, which evolves according to Schroedinger's equation without interruption.This is what makes the pilot wave interpretation a non-local, realist alternative to the Copenhagen interpretation. It was this theory that inspired Bell's inequalities test of non-local behavior of entangled particles, which was confirmed by the recent Nobel Prize-winning experiments of Aspect, Clauser, and Zeilinger. Here is the relevant quote from Bell himself: "When I was a student I had much difficulty with quantum mechanics. It was comforting to find that even Einstein had had such difficulties for a long time. Indeed they had led him to the heretical conclusion that something was missing in the theory: “I am, in fact, rather firmly convinced that the essentially statistical character of contemporary quantum theory is solely to be ascribed to the fact that this (theory) operates with an incomplete description of physical systems." Bell continued: "But in 1952 I saw the impossible done. It was in papers by David Bohm. Bohm showed explicitly how parameters could indeed be introduced, into nonrelativistic wave mechanics, with the help of which the indeterministic description could be transformed into a deterministic one. More importantly, in my opinion, the subjectivity of the orthodox version, the necessary reference to the “observer,” could be eliminated." In short, the key principle that resolved Bell and Einstein's objections to the Copenhagen interpretation's measurement problem was the elimination of the observer (and with it, wave function collapse) as an essential component of quantum mechanics.

    1:07:45 - I think the statement here is that the effect on the quantum *state* appears to be instantaneous. That state is shared by both particles, so to what extent you say something has happened *at* the remote particle is debatable - it's not clear where the quantum state *is*. In any case, though, we can't directly observe the quantum state. We can only observe observables. And in order to *recognize* the entanglement influence in observables drawn from particle B, we have to also have observable data from particle A. That data has to be communicated between the two, and that communication is subject to the speed of light limit. This precludes using the influence of entanglement to send information faster than light. So the shortest way I can see of answering that is that yes, the influence is instantaneous, but we can't "know anything" from it until later. It's as though quantum uncertainty "hides" enough from us to guard against violations of the speed limit.

    Dr. Sachs did write quite a lot on the incompatibilities of QM and GTR. His reinterpretation of field theory and effort to derive QM from GTR would seem as noteworthy as pilot waves. I like the mountaintop view of Dr. Sachs in seeking to derive linear QM from nonlinear GTR using quaternions as a common language. I was disappointed to see no mention in either the speech or book of Dr. Sachs, Hermann Weyl (gauge theory), Dr. David Hestenes (Real Quantum Mechanics and Modeling - see pg. 227 Einstein's Unfinished Revolution), Edwin T. Jaynes (information theory, statistics, etc.), or even Timothy Boyer and classical analogues of QM. I don't see a thorough bidirectional search being done in terms of research programs. I consider the top down view of Dr. Sachs to the bottom up view of Timothy Boyer. One could start with Edwin T. Jaynes' statement that Quantum Mechanics is not a physical theory because no physical principles went into it's development. Dr. Smolin almost gets into this in ch. 14 First, Principles, 225-252 e.g. pg. 227 of his book.

What you're really trying to say here is that in spite of that, it's not the theory that we "really want." I'd agree with that 100%. But the damn thing works, and it works extremely well, so far as it goes.

    It is important I think to acknowledge that the basic assumptions you are making are assumptions you can not explain at the moment, not say that they are laws of nature that are given out of nothing and that no further explanation is necessary. In fact Newton acknowledged that he could not explain gravity, but that an explanation of gravity would not be hopeless perhaps in the future. Newton formulated calculus, proposed gravity and could explain the planets movements by it. In fact I think that an acceptance that you cannot explain everything helps the investigative mind explain very much.

    While in all actuality Newton noticed himself that he could NOT explain the motions of the planets with this theory. The n-body problem was way beyond his analytical and numerical capabilities. It would take well until the second half of the 19th century to solve that part of the problem, at which point people began noticing that Mercury didn't move the way Newtonian mechanics suggested.

    Possibly the best explanation of the situation I've ever heard. In part because he was frank about the human element involved in the development of the theories. This is ironic, however, because as he admits (with refreshing clarity) at the beginning of the talk, he wants to describe the universe AS IF no human beings (including himself) were in it to interfere with its workings. But the universe---even if for only a blip in the totality of existence---does include us. We are part of it, and our interference is a part of it. Granted that there is something very wrong with reducing objective truths down to our petty human foibles and political causes, I also feel there is something just as wrong with pretending that those humans, as petty as we sometimes are, yet don't matter in the scheme of objective reality.

    Here's the problem. Objectivity IS science. As soon as we include ourselves, it becomes something closer to theology. This is an empirical discipline. IF we play a role in reality, that it is say "interefere", there needs to be SOME mechanism to measure that such that the idea is falsifiable (or, conversely, verified - even though science can only falsify never "prove"). As Einstein once said: "Do you believe the moon isn't there when you're not looking at it?"

    Mr. Berg, the indication that is blatantly clear hear is that the 'dimension' you are speaking of just happens to be traveling at, or near the speed of light. This would be analogous to the Heisenberg principle, since you cannot measure a STILL particle (that would be 0 Degrees Kelvin) since there is NO vibratory movement.

    The rule for predicting an outcome of measurement is based on the propagation of wave that determines probable outcomes. That is simple enough! QM affords us an equation that describes the propagation of a wave. The wave is a means of determining various outcomes. Do you want to know how likely a certain outcome is? Just solve the equation for the wave. Select the outcome of interest. Use the wave-solution of the equation that is appropriate to the situation. Do the calculation using that solution (Born's rule). Don't let people who write books for lay persons confuse you! What realism is does not come from philosophy. It comes from physics, from observation of the world - which is what physics is. When physics tells us that to know this and that at the same time is not possible, the impossibility lies in the nature of things. That is how things are. When we do physics, we learn how things are. We don't get that from philosophy. Remember, too, that how things seem to be when we examine them in the macroscopic world, which averages out much complexity, is not how they may be when examined more minutely. Prof. Smolin's assertion that QM is wrong is wrong. It is correct in the domain of our examination. When we look in other domains, we ought not expect to find an extension of it; only that at the boundary of the domains of observation one theory should be compatible with the other.

  • @halhelmboldt7739

    Mr. Smolin, I have a question, and I'm hoping you can answer it with the simplicity it deserves. It seems complicated when, at the fundamental laws of physics level, it should be simple, but it's not. I'm not sure about what is happening in the following described scenario. I'm sure you do. -- Thank you in advance! The [elongated] question (sorry): White light has all of the visible light frequencies in it, and when we look at white light we see white light. We can change the frequency using several methods, but changing the frequency of light (the color of light) using speed isn't one of those methods. Moving toward or away from an object shouldn't change the frequency of that light based on motion to arrive to any particular frequency. No matter the speed of motion, the speed of light is always constant. Therefore, a galaxy moving away should still be the inherent color of whatever majority it's overall light spectrum is; a blue galaxy, a red galaxy, a yellow galaxy, etc... Whether it is moving toward us or away from us (the direction of its motion) should be irrelevant as to what color it is since the speed of light, no matter the frequency, is constant. Therefore, how does motion have an impact on [the speed of light's frequency, then], when the speed of light is the speed of light no matter what? Motion should not have an impact on the frequency of light based on motion [speed]. If I am still wrong, why am I wrong? If I am correct, then what is going on with the speed of light C when it comes to the motion of a galaxy? Do galaxies moving toward us (Andromeda) also have a change in color to blue shift rather than red shift? If so, how? How is the frequency of light different from the speed of light? A red star is a red star because that is the frequency of a red star. A blue star is a blue star because that is the frequency of a blue star. But when it comes to the inherent color of a galaxy, it should remain its inherent color regardless of its motion. A blue star doesn't shift to red because it's moving away from us. Or, do they? If they do, how is this possible when the speed of light is unaffected regardless of the direction and speed of motion?

Your word "relative" is telling me, then, that no matter the medium light is traveling through, the speed of light is relative through any medium, and the frequency of the wavelengths in light remain the same no matter what.

    When one puts up an equation (hypothetical), there too much assumptions upon which there are equally numerous variables which the equation has to take one or two or more as constant, otherwise it can't stand, which is not the case in the reality of the universe.
