JohnMnemonic Posted August 5, 2018 Posted August 5, 2018 Quote No. Continually repeating the same falsehood over and over again does not make it true. Two light clocks maintaining a constant velocity with respect to each other, will both measure the other as running slow. As long as they maintain this constant velocity with respect to each other, there is no objective way to say which clock is really ticking slow. Exactly! I couldn't agree more... However according to some 50% of educated scientists, it is exactly, as he said - constant velocity causing real effects of time dilation... And this is exactly, what brings me here... https://www.quora.com/Special-Relativity-Is-time-dilation-due-to-velocity-just-an-illusion-Is-it-a-recording-mistake-Is-only-time-dilation-due-to-gravity-acceleration-real# It seems, that the theory of relativity is still causing a lot of disagreement between the scientists. In such case, it is not so bad idea, to trust my own intuition, instead of those with "authority" - and my intuition tells me, that we have to introduce some external force/field, or change the velocity/energy of an object, to physically affect the rate of time flow. If we speak about time dilation due to constant velocity, it can be only relative/apparent... At least I know, that I'm not alone on this "battlefield"... -2

This experiment has been done many times now and always confirms the predictions of SR. Ahh, are you talking about the famous Hafele–Keating Experiment? Of course, it's hard to argue with real life observations (although there are some people, who claim, that those results were altered, but let's leave it for now). However there's nothing what wouldn't allow us, to argue about the possible causes of observed effects. By an accident, I've made a short animation, which shows a simplified version of this experiment: According to the mainstream theory, time flow inside the plane which was moving eastward, was slowed down, because it's velocity was increased, while westward moving plane experienced higher rate of time flow, because he was moving slower... But I can still give you 2 different explanations... - time flow rates inside the planes changed during the time, when they were accelerating. Plane, which started to increase his speed in westward orientation, started to decrease the distance to the clock on the planet's surface, while the one which was accelerating to the East, started to increase the distance. - while all velocities, smalller than c, are relative, pilots of planes are able to notice the difference between the distances, which they passed during the flight - they just need to look at the Sun. Plane, which was moving westward circled around Earth from noon to noon just once, while the one moving eastward, made 3 full circles during the same time (I'm talking about animation, not the actual experiment). To maintain the symmetry of motion between the plane and the clock on the Earth's surface, time inside that plane had to flow at different rate - faster for the plane, which passed shorter distance and slower for the one, which passed a longer distance. It might appear, that this explanation is just a different version of the official one, but keep in mind, that all velocities are in this case relative, while distances are in fact definitive...

It would probably good for the science, if Einstein's theory would be once again proved... But, what do I know? BTW good, that there is still this thread. All I wanted, was to discuss some of my ideas and learn couple new things, but obviously some people think, that in fact I want to present a completely functional model of unified physics and a fully validated scientific theory, based on endless strings of sophisticated calculations, which will turn the entire world of science upside-down... Hmm, maybe I didn't say clearly enough, that I'm not a professional scientists. Or maybe I forgot to mention, that I'm a total amateur, who treats physics as a kind of hobby...? Or maybe some people don't like, when amateurs, like me start to talk about things, which are against the mainstream science...? It would be probably much better for all, if I would try to prove the flat Earth "theory", instead looking for new solutions for some old problems in physics... Anyway I really appreciate your input in the discussion - it is a rare sight, that people with actual knowledge have the will to speak with amateurs, like me Most of so called "scientists" try only to improve their self-confidence and prove, how smart they are...

Well in my case as a fellow amateur, when I find another amateur claiming that some part of mainstream science is wrong, and realizing that the mainstream incumbent versions/theories etc, had needed to also run the gauntlet so to speak, and pass muster and repeatable experiments confirming them, like SR/GR, it beggars belief in my opinion.

In other words avoiding professional scrutiny in most cases and the scientific methodology. Yes, that raises my hackles and makes me stop and think. https://en.wikipedia.org/wiki/Criticism_of_the_theory_of_relativity Criticism of the theory of relativity: "Criticism of the theory of relativity of Albert Einstein was mainly expressed in the early years after its publication in the early twentieth century, on scientific, pseudoscientific, philosophical, or ideologicalbases.[A 1][A 2][A 3] Though some of these criticisms had the support of reputable scientists, Einstein's theory of relativity is now accepted by the scientific community.[1] Reasons for criticism of the theory of relativity have included alternative theories, rejection of the abstract-mathematical method, and alleged errors of the theory. According to some authors, antisemitic objections to Einstein's Jewish heritage also occasionally played a role in these objections.[A 1][A 2][A 3] There are still some critics of relativity today, but their opinions are not shared by the majority in the scientific community" https://en.wikipedia.org/wiki/Criticism_of_the_theory_of_relativity#Acceleration_in_special_relativity Acceleration in special relativity[edit] It was also claimed that special relativity cannot handle acceleration, which would lead to contradictions in some situations. However, this assessment is not correct, since acceleration actually can be described in the framework of special relativity (see Acceleration (special relativity), Proper reference frame (flat spacetime), Hyperbolic motion, Rindler coordinates, Born coordinates). Paradoxes relying on insufficient understanding of these facts were discovered in the early years of relativity. For example, Max Born (1909) tried to combine the concept of rigid bodies with special relativity. That this model was insufficient was shown by Paul Ehrenfest (1909), who demonstrated that a rotating rigid body would, according to Born's definition, undergo a contraction of the circumference without contraction of the radius, which is impossible (Ehrenfest paradox). Max von Laue (1911) showed that rigid bodies cannot exist in special relativity, since the propagation of signals cannot exceed the speed of light, so an accelerating and rotating body will undergo deformations.[A 16][B 7][B 8][C 4] Paul Langevin and von Laue showed that the twin paradox can be completely resolved by consideration of acceleration in special relativity. If two twins move away from each other, and one of them is accelerating and coming back to the other, then the accelerated twin is younger than the other one, since he was located in at least two inertial frames of reference, and therefore his assessment of which events are simultaneous changed during the acceleration. For the other twin nothing changes since he remained in a single frame. Much more at both links.... Edited August 6, 2018 by beecee

And yet you repeat some statements, without giving a single thought about them... "Time doesn't flow for light..." Why? "Because the theory says so...", "Because everybody accept the SR - so it has to be correct...". "It's incorrect to use photons as frame of reference" Why? "Because SR doesn't allow it...", "Because Einstein said so...". You see, this is the difference between us - I won't accept any claim, without spending some time, thinking about it... You accept claims, just because everybody tell you, that you have to accept them... I accept them, only when I understand their meanings and only after they will make sense for me... If something doesn't make sense, or can be easily disproved by well known facts, then I reject it - and until someone won't prove me, that it is in fact correct, I will treat it as useless junk (no matter, if it was Einstein, who said so, or if everyone around tries to force my acceptance). Simple and well known fact, that each photon has it's own timeline/history proves clearly, that it has to experience flow of time - this is for me more than enough, to conclude, that Einstein made in this case a mistake. And because, couple minutes of thinking is enough, to figure out a solution, which will allow me to use photons as reference - it is clear to me, that the issue is not in the idea, to use speed of light as a reference, but in the theory, which gives us invalid results... When I see, that observations don't match my predictions, my first guess is, that there's something wrong with the model - and not that 70% of mass in the Universe is invisible and beyond any kind of perception....

I have just one more question for you: What would you do, if you would notice, that a generally approved theory is inconsistent with observable reality? Would you try to fix the theory, or would you assume, that something has to be wrong with reality? Before you will answer, think about the non-observable (non-existant?) dark matter.... I need also to mention about a very interesting fact - it seems, that since according to SR, it is impossible/invalid to describe the relation between photons and any physical object, there's no way of making a working model of this theory (which is actually based on the speed of light) - as we are simply not able to represent physical objects together with light in space... Funny, because relativity Doppler's effect describes the speed of light in relation to a moving source - so, obviously any visualisation of Doppler's effect is against the SR....

To help you understand, answer me this one simple question. In a universe where SR applies but there is only one frame, how fast does time flow, does it matter how fast that frame is moving? In relation to that closed thread, I had quite a detailed post prepared, but I lost it all as the thread was closed. Here is the info as well as I can remember. Looking at your responses it is clear you are not fully up to speed on classical (pre relativity ) mechanics. You cannot hope to understand the finer points of Relativity without this knowledge. Here is an Oxford University book that treats classical mechanics and then moves into SR and elementary GR in a way that is accessible to someone with high school Maths and Physics. It introduces briefly but does not use the more esoteric notation such as Einsteins's summation notation, contravariance and covariance, tensors, forms and metrics. But it does not launch directly into a series of definitions about these and then densely obscure the rest of the book with them. Also it comes fully and reliably verified, unlike many of your references. I believe it has a simple derivation of the repeated Lorentz transform we were discussing.

There's an important difference between a theory and a working model The meaning of the word 'theory' is ambiguous: it can mean 'hypothesis' or 'model'. Sometimes the word 'theory' sticks, even when it is empirically proven to the bone. It is a statement of ill faith to argue that, because of the word 'theory', relativity is still a hypothesis. It is e.g used by creationists, when they say 'evolution is just a theory'. Be assured, special relativity is proven, and explains such a variety of phenomena as the colour of gold, the relation between electrical and magnetic fields, the fact that atmospheric muons can be measured at the earth's surface, the fact that accelerators like the LHC work, time shifts in GPS, etc etc. 1 hour ago, JohnMnemonic said: Many people thought the same about newtonian gravity... Well, for slow speeds Newtonian physics is still so precise, that we nearly never must use relativity. The 'border case' of special relativity gives you Newtonian mechanics.We also know that the domain of general relativity excludes situations where we also need QM. But whatever theory will follow, general relativity will arise as border case where we can neglect quantum effects. In both cases the new theory explains why the old theories worked so fine. 1 hour ago, JohnMnemonic said: Oh, then if time is flowing at sub relativistic speeds - why won't we extend this to 100% of c? Because it does not work: you have to divide by 0. But in the limit of velocity approaching c, time stretches, until at the asymptotic velocity of c, time comes to a halt. However only massless particles can (and must!) travel at c. 1 hour ago, JohnMnemonic said: Strange - according to you and the SR, the faster a frame is moving, the slower the time flows for it... Then what is the rate of time flow for a frame, which for one observer moves at 99% of c, while for another one, at 1% of c? Obviously you do not understand special relativity at all. Time dilation is something observed by an observer who has a certain speed relative to the clock. If the speed is different for yet another frame of reference that observer will notice another time dilation factor. For an observer travelling with a clock, i.e. with the same speed in the same direction, nothing happens. The clock runs as clocks use to do in our normal, low speed world. The paradox you seem to have discovered simply does not exist, and arises from your misunderstanding.

Einstein has been, and still is tested everyday and as far as I know has passed with flying colours and both SR and GR are still overwhelmingly the theories/models of choice, simply because they match observations far more precisely then anything else you can care to name, and of course continue making successful predictions.

Quote I have just one more question for you: What would you do, if you would notice, that a generally approved theory is inconsistent with observable reality? Would you try to fix the theory, or would you assume, that something has to be wrong with reality? As a lay person and an amateur, like yourself, I would make every effort to know the incumbent model/theory, I would question and wonder why over a hundred years or so that the real professional and experts in that field had not also realized this hypothetical inconsistency, and then if I was still certain that I had found some fault or anomaly, I would sit down and write a proper paper for proper professional peer review. But getting back to reality what you refuse to see is that scientific theories, even those as certain as SR and GR are being continually tested everyday by these aforementioned professionals, and everyone of them would dearly love to be able to find some fault or inconsistency in the task at hand, and guarrentee fame and fortune for themselves for the rest of their lives.

If more evidence happens to come to light invalidating this DM, then I'm sure those at the coal face will be forthcoming with such evidence and have it properly published for proper peer review. Quote I need also to mention about a very interesting fact - it seems, that since according to SR, it is impossible/invalid to describe the relation between photons and any physical object, there's no way of making a working model of this theory (which is actually based on the speed of light) - as we are simply not able to represent physical objects together with light in space... Funny, because relativity Doppler's effect describes the speed of light in relation to a moving source - so, obviously any visualisation of Doppler's effect is against the SR... .Again do what you need to do to bring any of your mythical objections re SR and as an extension, GR to professional attention. In the meantime I believe you are confusing the Doppler shift with cosmological shift and in other circumstances, gravitational shift. In the meantime SR and GR both at this time stand as unchallenged. Edited August 6, 2018 by beecee

Obviously, that domain is limited, just like for any other model of physics. For example, Newtonian gravity is valid in the weak-field, low-velocity domain, but fails miserably outside of this. Likewise, we expect relativity to break down also at some point, presumably in the domain of quantum gravity. That does not make it wrong though, any more than relativity makes Newton wrong; it’s just a question of getting the domain of applicability right. 2

In a universe where SR applies but there is only one frame, how fast does time flow, does it matter how fast that frame is moving? To be honest, I'm against the idea, that a constant velocity is causing physical time dilation. Of course I don't have nothing against relative time dilation - but then we would need also a second frame... Quote In relation to that closed thread, I had quite a detailed post prepared, but I lost it all as the thread was closed. Here is the info as well as I can remember. Looking at your responses it is clear you are not fully up to speed on classical (pre relativity ) mechanics. You cannot hope to understand the finer points of Relativity without this knowledge. Here is an Oxford University book that treats classical mechanics and then moves into SR and elementary GR in a way that is accessible to someone with high school Maths and Physics. It introduces briefly but does not use the more esoteric notation such as Einsteins's summation notation, contravariance and covariance, tensors, forms and metrics. But it does not launch directly into a series of definitions about these and then densely obscure the rest of the book with them. Also it comes fully and reliably verified, unlike many of your references. I believe it has a simple derivation of the repeated Lorentz transform we were discussing. Dynamics and Relativity W D McComb Thanks! I will check it...
Markus Hanke Posted August 6, 2018 Posted August 6, 2018 (edited) I find it difficult to fathom how anyone could claim that SR is inconsistent; after all, the relationship between inertial frames is given by a simple hyperbolic rotation. That’s it, that’s all there is to it - a rotation about some angle. Claiming that SR (between inertial frames) is inconsistent amounts to claiming that there are rotations that are not reversible. Can anyone show us an example of a rotation about some point and angle that is not reversible by counterrotating about the same angle? I guess not. Taking it further, beyond purely inertial frames, the claim of inconsistency would amount to saying that Minkowski spacetime permits violations of causality. While the formal proof of this one is more tricky, it should nonetheless be intuitively obvious that - since this spacetime is everywhere flat, and has a constant metric - no such violations are possible. This kind of discussion is just a waste of time, since the internal consistency of SR is not under any kind of contention. The only point that one could possible argue about is the question of whether SR is a good and valid model of the real world. Given that no violations of Lorentz invariance have ever been observed, it stands to reason that it is indeed a good description, at the very least within the domain of applicability that we can currently probe. And that’s a pretty wide domain. Edited August 6, 2018 by Markus Hanke

That’s it, that’s all there is to it - a rotation about some angle. Claiming that SR (between inertial frames) is inconsistent amounts to claiming that there are rotations that are not reversible. Can anyone show us an example of a rotation about some point and angle that is not reversible by counterrotating about the same angle? I guess not. Taking it further, beyond purely inertial frames, the claim of inconsistency would amount to saying that Minkowski spacetime permits violations of causality. While the formal proof of this one is more tricky, it should nonetheless be intuitively obvious that - since this spacetime is everywhere flat, and has a constant metric - no such violations are possible. This kind of discussion is just a waste of time, since the internal consistency of SR is not under any kind of contention. The only point that one could possible argue about is the question of whether SR is a good and valid model of the real world. Given that no violations of Lorentz invariance have ever been observed, it stands to reason that it is indeed a good description, at the very least within the domain of applicability that we can currently probe. And that’s a pretty wide domain. But still we can't get a valid result, if we want to use a photon as reference...
geordief Posted August 6, 2018 Posted August 6, 2018 (edited) Can the photon travel at less than c if it is making its way out of a gravity well? Would it have a FOR then? Also can its FOR when it does travel at c be expressed as a limit? (if it is the zeros/infinities involved that are the reason it can't have a valid FOR) Edited August 6, 2018 by geordief

I have trouble making the two reconcile. Which is it? Do you know about the experiments, or do you think that more precise experiments have not been done? I was talking about the repetitions of Hafele-Keating experiment Quote I will state again: this is not part of SR (or, as far as I am aware, of any theory in physics). A photon is not in an inertial frame of reference. You cannot use c in a Lorentz transformation and get a sensible answer. Here's nice movie, which shows the problem: My question is: why we can't we use different transformations, to make light stationary? We can still rotate or skew the diagram. No one knows, how the relative motion of photons behave at the speed of light - photons don't have to move at the same speed for other photons... I need to think about it - sadly I don't have such nice tool as this guy... Quote We do it all the time. The speculations forum is well-populated with threads from people who think SR is flawed. Universally these people have been shown to not understand relativity, or how science works, or how to do math. Sometimes all three. But do you also completely ignore links to publications and assume, that they are just some rubbish? Quote "Daring" to disagree is one thing (and really, it overstates the alleged bravery required), but coming up with an argument that has any merit is quite another. As Markus pointed out above, most of the links are not credible sources, nor are they peer-reviewed, and peer review would likely clear out the worst of the clutter from folks who do not understand relativity. links, which I posted in the response to Markus Hanke seem to be ok... Quote My invitation stands. Pick one, if you are prepared to defend it. Ok, I'll try... Give me just some time... 1 minute ago, JohnMnemonic said: My question is: why we can't we use different transformations, to make light stationary? We can still rotate or skew the diagram.

Ok, I can guess already, what happens after the rotation of time-space diagram - for a stationary photon, photons in motion would appear to move instantly (at 0t)... Skewing requires better imagination... Maybe I'll try to draw it...

A flight from London to the US and back; they didn't need to go around the world because the clocks were better. There was also an experiment where the plane just did a "racetrack" path for an extended period of time. And surprise! Wikipedia covers all this https://en.wikipedia.org/wiki/Hafele–Keating_experiment#Repetitions But here's the thing: once you have confirmed the theory, you tend to move on, and do experiments that rely on the experiment being correct, rather than a straightforward test. So if you look for a bunch of experiments that are an improvement of Hafele-Keating they may not exist, because we now do more advanced work. GPS, for example, wouldn't work unless relativity were correct. All of the really precise tests of GR wouldn't work if the basics were wrong.
