Twin paradox (Pete and MacM)

Status
Not open for further replies.
MacM and James R are no longer talking to each other, but at each other. Each admits / claims they have destroyed the other’s position at least 10 times, by repetition. This has been good for me as I only read carefully ~10% of the posts, so when allowance is made for fact that I sometimes read the same argument, (in words sufficiently different that I don’t immediately notice or remember it is the same) twice, I am getting about 80% of their posts content. I agree with James that Pete’s post 685616 is excellent and cuts directly to the heart of the matter.

MacM The burden of disproving SR is on you. As Pete points out in 685616, all he, James, and to a lesser extent, I must do to defend SR from your attack is show some flaw in the attack. We need not undertake the impossible task of proving SR is correct (No theory can be proven correct – only the accumulation of a lot of evidence in its favor, with no empirical evidence against, leads most people to assume it is correct.) I think you agree to this.

As I understand it, the essence of your attack is “I have given a scheme to display in B’s moving rocket ship (I am avoiding the word “synchronize” by using “display”) a clock that ticks at the same rate as Earth bound clock A.” (I also avoid immediately specifying the frame in which A’s ticking is to be “matched” by B’s display.) If this is not the essence of your attack, please state it as succinctly possible (or correct my attempt).

The difficulty with this attack, I believe, is that fundamentally your attack / argument is based on your unproven, but firmly believed and highly plausible idea: “That there can be only one reality – hence in ANY inertial frame, clock A ticks at one universal rate.” (In short, UT is the true reality.) Even if this were true (and I think not) this is wasted effort on your part until you can DEMONSTRATE it is true to us who think it is false. By assumption / firm belief, you are affirming UT and DISALLOWING the possibility that in B’s frame the real tick rate of clock A, I call it Ab, could be different from the proper rate Aa, but this is exactly what James et. al. (me included, with my muons) believe. We believe Aa – Ab is not zero and want you to PROVE that it is zero before that we congratulate you on a successful attack against SR.

The following may help you to appreciate the why your attack is meeting resistance: No matter how fervently /strongly a evangelist believes God exist, he can not use the assumption/ firm belief “He does” to convert the atheist. You can not use the “fact” Aa – Ab = 0 (even if true!) to convert us to UT any more than the evangelist can use the “fact” “God Exists” (even if true) to convert the atheist. The evangelist must demonstrate that God exists and you must demonstrate the Aa – Ab = 0.

I admit your argument has great natural appeal. It is hard to believe physical processes, like muon decay, or flexing of the 100MHz crystal controlling a moving transmitter could in truth have their process rate in frames other than their rest frame be actually changed instead of just appear to be changed, but what we find easy to believe is not always the way the world works. For example, I have never actually seen an interference pattern produced in photographic film by an exposure so weak that one can be confident that two photons rarely exist (dare I say it) “at the same time.”

I know something about the exposing of film (called the “reciprocity failure”) that makes me even willing to look skeptically upon this often-cited example of counter-intuitive nature where each photon goes through two side-by-side slits. But I have made a demonstration of the fact that each photo can go by two different paths, so I tend to believe Young’s double-slit interference is demonstrably true in very weak light at least when the photons are photo-electrically detected. (steadily scan detector, plot detection rate vs. position) What I did follows:

You can make two optical paths along different sides of a rectangle that later merge with two half silvered mirrors and two full silvered mirrors in two different ways. In one way the half-silvered mirrors are both on a side, providing a straight-line path through both from source to display screen and the other way has them at the diagonal corners of the rectangle. In this latter case both paths are always the same length and this is the way you will see the experiment described in lab manuals. In the “non-standard” geometry, the “side path” is longer by the length of the two legs perpendicular to the “straight through the half silvered mirrors” path of the standard geometry. If you keep this extra length short (I’ll quantify short in a moment) you can demonstrate interference with this non-standard geometry also, but as you make it progressively longer, the interference fades out.

In the case I actually did, the fading was noticeable with about 20 cm of extra path and the interference was gone (to my eye) by 40 cm. The exact numbers depend on the nature of the light source. It takes time for the electron to make the transition from the excited state to the lower state. During this period, you can think of the transition as pumping out cycles of the optical frequency. That is each photon wave has a finite length, called the “coherence length” (forget about LASERs, which stimulate each new photon to get into phase with those that are passing by – I am talking about relative low density gas discharge light sources) Even in these “incoherent light sources” the “head” of the photon is coherent with its own “tail,” but not with the photon emitted by some other atom.

To see interference with two paths and incoherent light sources you must keep the difference in the two path lengths significantly less that the coherence length. For me, with my physicist hat on, this proves that each photon is interfering with its self, after having gone over two different paths. I have seen this with my own eyes. Thus MacM I know there are physical facts that are both self-evidently false to any human that can think clearly and yet are true. I believe SR is one, based on all the things it predicts correctly. When I take my physicist hat off, I would much prefer to believe in UT as that seems to be self evidently true.

It seems to be ridiculous that each photon can pass through two different paths, or that a moving muon’s decay rate is really different or that a 100Mhz crystal can really flex at a much lower frequency just because they are moving relative to me! We must tell them to stop this nonsense! It is disturbing to humans (even to some physicist :rolleyes: ). At times, even as a physicist, I too want some other explanation, consistent with what is “obvious.” I too want to grasp at any straw, such as your atmospheric energy is affecting the decay rate or some “either drag resonance” is setup in the optical geometry and this is what causes the interference pattern and the photon” really goes by only one path but it is being refracted to the locations of the peaks of the pattern by the standing density variation waves of the either associated by the resonance of the geometry, etc.

A physicist, much smarter and better educated than me, (David Bohm) has written several books (the one I own is called “the undivided universe”). He, like you and me, wants nature to behave as it obviously should and he is clever enough to have redone quantum mechanics to get all the same predictions yet put the photon through only one path. (That is why I bought his book. As far as I know he accepts SR.) But even relatively dim witted me, found a fundamental problem with his theory, which I will explain privately if you like as my posts are always too long. (At least the are infrequent.)

MacM, you were pleased (Called me the most honest here etc.) when I, based on a skim of James’s first referenced thread (679604), I ventured a PRELIMINARY, opinion that James had failed to destroy your attack (by showing how your scheme fails to guarantee B’s monitor is ticking the same as A is ticking IN B’s FRAME. My opinion has now reversed. I think James has proved your attack flawed. Why the switch in next paragraph – skip it if you don’t care why.

When skimming 679604 that James said destroyed you scheme /attack, I started to read a post that compared “Newtonian Doppler” and “Relativistic Doppler,” but stopped reading it quickly because (Unless memory fails me, the first formulae of the “Newtonian Doppler section” only reduced the Doppler shift of a receding transmitter by a factor of two, even in the limit as v approached c.) I think Newton believed (or would have believed if he ever thought about it) that if you were separating from a radiation source at nearly the speed with which it waves were coming to you then the Doppler shift would be much greater than two. I am sure he would think that if you separating from the source at that speed of the waves’ advance, you would be sitting on a fixed part of one cycle (I.e. in a DC field). Thus I thought, “no point in going further in this post” and prematurely concluded that James would fail to defend SR with this type of counter attack. I now am getting the impression that some or all of you are separating out the Doppler effect from the relativistic ones. – It has been slightly more than 40 years since I understood SR – One summer I did almost all the problems in Leighton’s book, (Modern Physics – think it is called) and there is a chapter on relativity in it. Thus I do not still possess the ability to calculate with confidence nor do I care to recover it. My only interest in physics today has to do with the economic health of my still preschool grandchildren. I have tried to improve their future by using some of the physics I still remember (more at DarkVisitor.com).

Pete’s excellent post has brought the issue in to sharp focus. The ball is in your court. Show us, without assuming Aa - Ab = 0 that UT exist. I for one would love to believe this, not the nonsense about crystal flexing, muon decay rates being motion depend. But I can’t keep postulating some new mechanism ad hoc to explain each experimental fact SR successfully predicts. Occam will take his razor to me!

Now James if you are still here, thanks for the information. I thought that there was little energy transfer between the muons and the atmosphere based mainly on two things. One is the fact that Cerinkov radiation exists proves they have not significantly been slowed by this interaction. The other is the fact that radioactive decay is perhaps the most random process known. I.e. impossible to modify by electric, magnetic fields, chemicals near by on an atomic scale, etc. Ironically, only what seems totally unreasonable (movement) changes it. (Muons do get to ground, all agree when their short life does not permit this even at v=c.)

Except for the rare event of a collision with the nucleus (like the ones which multiply a single particle into cosmic ray shower) the atmospheric interaction would be via the electric field (This is the cause of the Cerinkov)when one comes close to an electron on N2 or O2 usually. Electric fields much stronger than any macroscopic one man can make exist within certain ionic crystals at (lattice sites) More than half of all Ph.D. granted at JHU when I working on my mine (in another area) were studies of how the energy levels of rare earth elements are shifted by these internal fields (called the Stark effect) I am sure if electric fields could modify the decay rate of a radioactive particle, then someone would have incorporated a known quantity of them insides such a crystal where the lattice site field is enormous and waited a few years (if need be) before making a chemical evaluation of how many have decayed – I.e. measured the effect of strong electric fields on decay rate. Unfortunately for the people who have tried this, the rate must not have changed and instead of at least being nominated for the Physic Nobel, they were lucky to get their negative result published in some obscure journal.

Thus MacM’ ad hoc explanation, even bolstered by a Russian journal article, which I gather only noticed a trend / change in published values of decay rates, is for me as ridiculous as the fact the muons reach the surface, but the later is fact and the former is inconsistent with the many experiments that must have tried directly to change the decay rate via electric fields. MacM this “atmospheric energy transfer” is very small (they are still faster than c in air as Cerinkov proves) and would be by the electric field, not some mystical force, which would be very weak compared to that man can make between condenser plate etc and many orders of magnitude less than nature makes inside crystals.

Thus given the disagreeable choice between something (SR) that just seems ridiculous to humans, but is confirmed in many experiments and something ad hoc cause by electric fields which are known to be many orders of magnitude less than the electric fields nature makes, that still don’t show any effect on decay rates, I think the choice is clear.

Even if protesting all the way how ridiculous it is, you should, I think, stop inventing a new ad hoc explanation to explain each of all the things SR explains at once, with one model, which has had many predictions very precisely confirmed (assuming that these ad hoc explanations are false.) Especially you should abandon this ad hoc one about weak electric field’s “mediated energy transfer” changing the decay rate when fields many order of magnitude larger ones can not. I think a good skeptic like you (I hear tell that you are even testing gravity theory!) would be find it unbelievable that each of these different ad hoc explanations just happens to make the precise effect that SR predicts.

If your previously (and I hope humorously) noted offenses against “god Einstein” don’t make you fear for your soul, then fear for your life --- Occam just called to ask me where you live.

Actually I disagree with your assumption that I am disproving (or attempting to) SRT. I am proving that SRT is perception and not physical reality. That is it is purely observational.

As I understand it, the essence of your attack is “I have given a scheme to display in B’s moving rocket ship (I am avoiding the word “synchronize” by using “display”) a clock that ticks at the same rate as Earth bound clock A.” (I also avoid immediately specifying the frame in which A’s ticking is to be “matched” by B’s display.)

(me included, with my muons) believe. We believe Aa – Ab is not zero and want you to PROVE that it is zero before that we congratulate you on a successful attack against SR.

No congratualtions are required. The only thing required is for you to go through the attached case which has numbered steps of mathematically derived relationships and to point out in actuality where that numbered step is inconsistant with any physical and/or mathematical notion currently used in physics and/or is inconsistant with assumptions of Relativity.

It seems to be ridiculous that each photon can pass through two different paths, or that a moving muon’s decay rate is really different or that a 100Mhz crystal can really flex at a much lower frequency just because they are moving relative to me! We must tell them to stop this nonsense! It is disturbing to humans (even to some physicist :rolleyes: ).

I do not find the double slit phenomena difficult to accept, so I am skipping much of your jpost above. The only thing that is unclear to me would be if in bifurcating through the slits is that the photon should distribute its energy in into each slit such that the total energy remains constant. If not then we have another issue to address.

MacM, you were pleased (Called me the most honest here etc.) when I, based on a skim of James’s first referenced thread (679604), I ventured a PRELIMINARY, opinion that James had failed to destroy your attack (by showing how your scheme fails to guarantee B’s monitor is ticking the same as A is ticking IN B’s FRAME. My opinion has now reversed. I think James has proved your attack flawed. Why the switch in next paragraph – skip it if you don’t care why.

I have read your paragraph and rely upon you to show in very specific and supported terms, not ad lib, that a particular numbered step is inconsistant with our knowledge , not simply because it is so stated in a theory.

Pete’s excellent post has brought the issue in to sharp focus. The ball is in your court. Show us, without assuming Aa - Ab = 0 that UT exist.

You assume to much to say I assume UT. I have not. I assume only that the rules of Relativity apply and that the mathematics of the case as numbered and outlined attached hereto are valid physics and mathematics.

That leaves the onus on you to show the flaw. Failure to being able to do that short of "Because SRT says" would mean merely that SRT is observational and doesn't affect physical reality, hence the twin doesn't actually get younger.

Thus MacM’ ad hoc explanation, even bolstered by a Russian journal article, which I gather only noticed a trend / change in published values of decay rates, is for me as ridiculous as the fact the muons reach the surface, but the later is fact and the former is inconsistent with the many experiments that must have tried directly to change the decay rate via electric fields.

You should note that my assumptions are that it is the energy of detection due to the impact with the scintillation crystal and not merely penetrating the atmosphere is the root cause of change in decay rates. The photon on impact is a major event internally to the structure of the muon.

I think a good skeptic like you (I hear tell that you are even testing gravity theory!) would be find it unbelievable that each of these different ad hoc explanations just happens to make the precise effect that SR predicts.

For what it is worth, I have indeed been testing gravity and have seen data that suggest (if repeatablity is confirmed by others) that GR, as well as Newton, are invalid concepts.

See "UniKEF Gravity Testing" in the main menu of this site:

Give me your explanation for the data.

If your previously (and I hope humorously) noted offenses against “god Einstein” don’t make you fear for your soul, then fear for your life --- Occam just called to ask me where you live.

Actually I have found many things ascribed to Einstein which he infact didn't say and often times actually said the opposite. He may infact champion my efforts to clarify Relativity. :D

That is acceptable. What is not acceptable is the AD HOC FIAT declarations which violate other Relavistic conditions such as prop #1 in the attachments.

Simultaneity is achieved and physical reality is in opposition to the theory of Relativity. Relativity is relagated to observational distortions.

1) This isn't what you previously claimed to be doing... selective memory is grand. The only problem is that you have to meet people who you don't want to remember over and over. (Feel free to replace 'meet people who' with 'admit things that'.)
2) Your perception vs reality argument is just as baseless as you've shown no empircal evidence that what we observe is not 'reality'... or that we can determine reality through our observations. This is a science/philosophy question which NOBODY has solved. Don't pretend like you suddenly know a good way to define objective reality unless you can back it up.

I'll note that you haven't choosen to address the issue at all and are making AD HOC FIAT statements. Please address any numbered point which you claim is incorrect. We can then have a real discussion.

To paraphrase JamesR:

I just did... please learn to read.

Nothing in your scenario actually proves what time is 'reality'.
 
Persol said:

I have to take it from this that you can supply no valid complaint about any step shown. The conclusion therefore stands pending a valid supportable claim of something in error or false by Relativity and/or mathematics.

The scenario is within the descriptions given by Relativity. I do not appologize that the results conflict with the arguement that Relativity is physically real.
 
the results conflict with the arguement that Relativity is physically real.
Please explain why this is so? (Completely ignoring the fact that this has been demonstrated in particle accelerators)
 
Persol said:

It is so because it is a correct mathematical result. Particle accelerators do infact add energy to the particle. the affect may be therefore energy related and not time related.

Energy is also a relative notion; however to achieve a change in energy it undergoes acceleration and internal forces.

MacM, I am so rusty I squeak when it comes to the math of relativity. Once I could at least read with some comprehension the very-compact, highly-subscripted, tensor equations of GR, but you forget a lot when it is never used for 40+ years. Thus, I may not be able to find fault with your attachments. I hope to click on them soon and get back to you, but a few comments first:

You said:

“I am proving that SRT is perception and not physical reality. That is it is purely observational.”

I don’t agree that is what you are doing. We SR men (and ladies) think that it is really true that Aa – Ab is not zero (That UT does not exist) and this is why muons moving in the Earth’s frame reach the ground. We don’t seek an additional “ad hoc” explanation. That is: we think their clocks are actually running slowly or time dilation exists, not just as a perception (The muons don’t know I am looking and they surely don’t perceive anything!) We SR people believe this because we think SR is making real predictions about physical processes such as how far the fast moving muon can travel before it decays, not that SR is only predicting how some physical process on a fast moving train will APPEAR to the man in the station. Thus, you may not intend to, but from our POV you are trying to disprove SRT.

You do still believe UT really exists and time dilation does not, don’t you? The existence of UT (or not) is like the existence of God (or not). Neither “X (or not)” is a perceptual question - both are questions of fact, truth if you like. I suspect you agree when X = God. If so, you must agree (and admit you are trying to disprove SR) when X =UT. Surely you do not argue that the question of /god’s existence or not is only a perceptual, not a factual, question.

(In your text I quoted above, I think you meant as the last sentence: “That the results predicted by SRT are purely observational.” A theory is neither observational nor real. It is a theory, and my comments were assuming this more careful statement is what you meant.)

Much to my surprise, you now focus on (at least in part) on the “observation / detection / scintillation’s photon’s interactions” as the cause of the “extension” of the muon’s life instead of your prior “atmospheric energy interactions” when you said:

“that it is the energy of detection due to the impact with the scintillation crystal and not merely penetrating the atmosphere is the root cause of change in decay rates. The photon on impact is a major event internally to the structure of the muon.”

I have no idea what “the structure of the muon” is, so I will not comment on this part. However I think the remainederr is a terrible blunder on your part, (blunder for you side) unless you think the muon is clairvoyant and knows it can live to reach the ground because when it does get to the ground, it will get the extra help you now speak of as being partially the cause of the half-life extension that permits it to get to the ground. I will let you retract this new claim without further comment on it if you like.

Perhaps you now feel you need some new reason, even if it implies clairvoyance, because of the argument I advanced about internal electric fields in crystals, (which are orders of magnitude greater than any almost all muons experienced on the way down through the atmosphere by interacting with the electrons of N2 and O2), produce no detectable change in any radioactive decay rates, (so long as the crystal containing them remains at rest, and even if rapidly moving, you should find it strange that the electric field only then becomes effective, not SR, but if you want this new ad hoc explanation also, I can’t stop you.).

Remember there are only four forces in nature (as far as we know). Clearly the extension of the muon life which lets it get to the ground is not due to either of the nuclear forces. Their range is far too short to do any thing except in the rare event that the muon actually hits the tiny nucleus. I think your work with gravity will permit you to agree with me when I say it is much weaker than the one remaining force (electrical). Because I have shown that even in crystals, where the electric field is much stronger, no change in decay rates has been observed, you either have to postulate a new fifth force or do what you have just now done, postulate the scintillation photons add to the muon’s half life despite its implied clairvoyance. We agree that their half life is greatly extended IN FACT, not as a perception, because they do make it down to the ground from the high up in the atmosphere. What we disagree upon is why. I say it follows, like many other observations, directly for the time dilation moving objects experience. You dispute this and so you need to find some (ad hoc) explanation, which for strange unexplained reasons, just happens to produce the same results as SR predicts!

I have come to know you well enough (you are very clever) that I expect you will find some reason why you should not be embarrassed by this, but I can’t find any. I think you should be embarrassed to suggest the latest ad hoc explanation of something that we agree is fact, (muon do get down), like the two you previously offered, also “just happens,” to make the same extension to muon life as SR’s predicted time dilation.

SR’s time dilation with its precise quantification is “one explanation fits all” shopping – you must invent a new explanatory mechanism for each different thing SR explains with one constant, mathematically precise, reason, and worse for you is when that ad hoc explanation is shown to be nonsense, you must invent a replacement which also just happens, for still unexplained reasons, to match SR’s “one explanation fits all” with the same precision! But as I said you are clever and seem to be able to do this, usually, even if it to later also falls to reason or facts as your two prior ones have.

Finally, I want to comment on your statement:

“You assume to much to say I assume UT. I have not.”

I will just be repeating what Pete and James have said better than me, but at least I invented “Aa” and “Ab” to refer to respectively clock A’s tick rate in its own frame (subscript a) and the true (not perceptual) tick rate of clock A moving in frame B (subscript b). I understand your position to be that there is only one reality. Hence clock A has only one tick rate. Thus Aa = Ab. Even if frame B is in uniform motion relative to frame A so that a clock fixed at the origin of frame A is moving in frame B. That is UT exists if and only if of necessity Aa – Ab = 0 for all inertial frames. I have even admitted this is a very reasonable argument (one reality, one tick rate, one UT).

This plausibility is why I went into some detail about another very reasonable idea (Each photon goes by only one path in a set of mirrors where it must decide to either be reflected by a half silvered mirror or pass through it.) explaining my personal observations of what actually happens and why. Unfortunately nature is not always a slave to what we think is reasonable. Thus we SR people insist that you at least allow the possibility that Aa – Ab is not zero and then ask you to prove that the reasonable assumption that it is always zero to be correct. As far as I know, you have never proven that Aa = Ab. Consequently I am forced to assume that this is your assumption. I think I am fully with in my logical rights to assert you are assuming this reasonable Aa =Ab or UT until you show that it is a proven fact, not a “fact” you only find so reasonable that it must be true. – A fact so self evident that you can use it when needed without proof and yet continue making the claim that you did not assume it.

This is the central point of this whole thread. SR states clearly that Aa – Ab is not zero if the frame B is in relative motion compared to stationary frame A. It is the reason why SR predicts the heart of the astronaut twin has “ticked” less than his stay at home brother when they reunite later in life. You of course deny he is younger, because you assert Aa =Ab or UT is the unique reality. You assert that only one tick rate for a clock can actually exist. But I repeat, you have never proven this, so it reasonable for me to think you are assuming it. – I think you assume it because it is so plausible, as already stated (one reality , one tick rate, hence Aa = Ab)

Tell me why I am not justified in thinking it is assumed when you offer no proof that it is fact and yet use it as if it were fact, for example in the twin paradox to conclude the astronaut twin is not younger as SR predicts because all his clocks including his heart, all tick on UT, and do not slow down with his motion relative to say at home twin brother.

Defend your assertion in the above quote, that you have not assumed UT

Well, I really don't care waht James R believes other than your statement suggests that I have lied. Which I haven't and don't. Further we shall see. I returned on of the responses with a bit of goad and got a response back "We'll be in touch". So I'll post their final reply.

In the mean time you might try to advance something more than AD HOC FIAT statements advocating SRT conclusions and concentrate on showing (supportably) a flaw inthe numbered steps.

Pick one, state why it is wrong and then perhaps this thread can get legs and become useful.

You and I both. It has been 40 years since I was involved with mathematics to any substantial degree. But while mathematics are good they are not the ultimate truth. Relatvistics mathematics also predict singularities and infinities in physical realities. They do not exist and cannot exist even by definition of infinity.

“I am proving that SRT is perception and not physical reality. That is it is purely observational.”

I don’t agree that is what you are doing. We SR men (and ladies) think that it is really true that Aa – Ab is not zero (That UT does not exist) and this is why muons moving in the Earth’s frame reach the ground. We don’t seek an additional “ad hoc” explanation. That is: we think their clocks are actually running slowly or time dilation exists, not just as a perception (The muons don’t know I am looking and they surely don’t perceive anything!) We SR people believe this because we think SR is making real predictions about physical processes such as how far the fast moving muon can travel before it decays, not that SR is only predicting how some physical process on a fast moving train will APPEAR to the man in the station. Thus, you may not intend to, but from our POV you are trying to disprove SRT.

Not at all. Perhaps from your perspective SRT becomes worthless if it is only perception but lthe issue isn't the observations or test data but if it is perception of reality. I do believe any honest person has to conclude that it must be perception. To do otherwise is nothing more than an act of afith in SRT casting reason to the side.

You do still believe UT really exists and time dilation does not, don’t you?

I believe TD is an illusion and does not result in the twin returning younger than his brother. I am not claiming that the observation doesn't occur.

The existence of UT (or not) is like the existence of God (or not). Neither “X (or not)” is a perceptual question - both are questions of fact, truth if you like. I suspect you agree when X = God. If so, you must agree (and admit you are trying to disprove SR) when X =UT. Surely you do not argue that the question of /god’s existence or not is only a perceptual, not a factual, question.

Actually I would see the issue of God in a very simular fashion. Many believe in God but it is noting but a mind set and he is not a reality. Also. I am not bent on proving UT. I think we have some differances as to what UT means.

If you mean local proper times. Yes that is what I believe and that they are immutable . However there are no two local proper times (down to planck time distinctions) that are the same.

(In your text I quoted above, I think you meant as the last sentence: “That the results predicted by SRT are purely observational.” A theory is neither observational nor real. It is a theory, and my comments were assuming this more careful statement is what you meant.)

That is a correct interpretation.

Much to my surprise, you now focus on (at least in part) on the “observation / detection / scintillation’s photon’s interactions” as the cause of the “extension” of the muon’s life instead of your prior “atmospheric energy interactions” when you said:

“that it is the energy of detection due to the impact with the scintillation crystal and not merely penetrating the atmosphere is the root cause of change in decay rates. The photon on impact is a major event internally to the structure of the muon.”

I have no idea what “the structure of the muon” is, so I will not comment on this part. However I think the remainederr is a terrible blunder on your part, (blunder for you side) unless you think the muon is clairvoyant and knows it can live to reach the ground because when it does get to the ground, it will get the extra help you now speak of as being partially the cause of the half-life extension that permits it to get to the ground. I will let you retract this new claim without further comment on it if you like.

I too have no idea about the internal structure. My point dealt with the issue of the photon release which is a major transition of ineternal energy.

Your other point is well taken and valid. So I wwould have to still rely upon energy changes during transition through the atmosphere to account for their actual arrival. Let me also point out that energy content is also a relavistic notion. But the change in internal energy due to pressure, heating. static charge, acceleration and/or deceleration forces etc are energy changing external enfluences; whereas "Relative Velocity" perse' is meaningless to the muon since it sees itself as at rest.

Perhaps you now feel you need some new reason, even if it implies clairvoyance, because of the argument I advanced about internal electric fields in crystals, (which are orders of magnitude greater than any almost all muons experienced on the way down through the atmosphere by interacting with the electrons of N2 and O2), produce no detectable change in any radioactive decay rates, (so long as the crystal containing them remains at rest, and even if rapidly moving, you should find it strange that the electric field only then becomes effective, not SR, but if you want this new ad hoc explanation also, I can’t stop you.).

I have not proposed what specifically is the cause but only that it isn't relative velocity to the observer.

Remember there are only four forces in nature (as far as we know). Clearly the extension of the muon life which lets it get to the ground is not due to either of the nuclear forces. Their range is far too short to do any thing except in the rare event that the muon actually hits the tiny nucleus. I think your work with gravity will permit you to agree with me when I say it is much weaker than the one remaining force (electrical). Because I have shown that even in crystals, where the electric field is much stronger, no change in decay rates has been observed, you either have to postulate a new fifth force or do what you have just now done, postulate the scintillation photons add to the muon’s half life despite its implied clairvoyance. We agree that their half life is greatly extended IN FACT, not as a perception, because they do make it down to the ground from the high up in the atmosphere. What we disagree upon is why. I say it follows, like many other observations, directly for the time dilation moving objects experience. You dispute this and so you need to find some (ad hoc) explanation, which for strange unexplained reasons, just happens to produce the same results as SR predicts!

The clairvoyance issue I think has been addressed above. However, I do not thik you can limit this issue to one of four primary forces in nature but to actual energy changes induced by external forces by whatever means.

Here is where the Rusian data becomes interesting. Just what jpossible cause can you envision which would cause a cosmologically cyclic behavior on decay rates when the is no relative motion involved.

To accept your view I hope you have considered that to say the muon life is a function of relative velocity, that you must include the entire universe in which it lives and the relative motion it has to every other mass in the universe. For relative motion of cosmology to be affective you would have to believe that somehow a bulk cyclic relative motion of masses in the universe are harmonically linked to earth. I tend to doubt that cause. Somethingelse is clearly involved. That being the case to say the least the issue of relative velocity becomes masked and unclear and in light of my presentation it appears totally out of the question.

I have come to know you well enough (you are very clever) that I expect you will find some reason why you should not be embarrassed by this, but I can’t find any. I think you should be embarrassed to suggest the latest ad hoc explanation of something that we agree is fact, (muon do get down), like the two you previously offered, also “just happens,” to make the same extension to muon life as SR’s predicted time dilation.

Not nearly as embarrassed as I would be to think for even a coherent second that time has been altered for one party by relative motion seperating two parties. Relativity mandates that Relative means "Relative". As in if you say there is 1,000 Mps relative velocity between A & B, that A (per Relativity) claims B is receeding at 1,000 Mps and A is at rest. "Simultaneously" Relativity holds that it is equally valid that B can say he is at rest and it is A that is receeding at 1,000 Mps.

Under those conditions, imposed by Relativity itself, it is almost unimaginable that logical persons can advocate that only one party suffers an affect different or greater than the other. (Note - this view is for inertial systems only, acceleration is a change in energy state and one being accelerated to jproduce the relative velocity has external/internal energy shifts during such transitions.)

SR’s time dilation with its precise quantification is “one explanation fits all” shopping – you must invent a new explanatory mechanism for each different thing SR explains with one constant, mathematically precise, reason, and worse for you is when that ad hoc explanation is shown to be nonsense, you must invent a replacement which also just happens, for still unexplained reasons, to match SR’s “one explanation fits all” with the same precision! But as I said you are clever and seem to be able to do this, usually, even if it to later also falls to reason or facts as your two prior ones have.

And just what do you do when the "One explanation fits all" belief is shown to be nonsense? You go back to work and look for actual "Causual" inputs.

Finally, I want to comment on your statement:

MacM said:
“You assume to much to say I assume UT. I have not.”

I will just be repeating what Pete and James have said better than me, but at least I invented “Aa” and “Ab” to refer to respectively clock A’s tick rate in its own frame (subscript a) and the true (not perceptual) tick rate of clock A moving in frame B (subscript b). I understand your position to be that there is only one reality. Hence clock A has only one tick rate. Thus Aa = Ab. Even if frame B is in uniform motion relative to frame A so that a clock fixed at the origin of frame A is moving in frame B. That is UT exists if and only if of necessity Aa – Ab = 0 for all inertial frames. I have even admitted this is a very reasonable argument (one reality, one tick rate, one UT).

I think others see to much in all this. I would not expect to see this group or for that matter any group simply cast away 100 years of indoctrination. But nor do I find it acceptable that they choose to argue nonsensical issues and to attempt to evade facing the conflict by casting innuendo and slander at me.

Once again I have no agenda to overturn Einstein. I do have an agenda to advance science and if I do nothing more than clarify issues which for to long have been locked in the closet because they upset the status quo then I have achieved my goal.

This plausibility is why I went into some detail about another very reasonable idea (Each photon goes by only one path in a set of mirrors where it must decide to either be reflected by a half silvered mirror or pass through it.) explaining my personal observations of what actually happens and why. Unfortunately nature is not always a slave to what we think is reasonable. Thus we SR people insist that you at least allow the possibility that Aa – Ab is not zero and then ask you to prove that the reasonable assumption that it is always zero to be correct. As far as I know, you have never proven that Aa = Ab. Consequently I am forced to assume that this is your assumption. I think I am fully with in my logical rights to assert you are assuming this reasonable Aa =Ab or UT until you show that it is a proven fact, not a “fact” you only find so reasonable that it must be true. – A fact so self evident that you can use it when needed without proof and yet continue making the claim that you did not assume it.

I too agree that nothing in nature must be logical to us but I do think our conclusions should at least fit our own propositions and mathematical conclusions. You can't go around changing things to suit different situations.

Time Dilations does just that. It casts aside more basic assumptions made in Relativity and ignores that TD is in conflict with Relativity itself.

This is the central point of this whole thread. SR states clearly that Aa – Ab is not zero if the frame B is in relative motion compared to stationary frame A. It is the reason why SR predicts the heart of the astronaut twin has “ticked” less than his stay at home brother when they reunite later in life. You of course deny he is younger, because you assert Aa =Ab or UT is the unique reality. You assert that only one tick rate for a clock can actually exist. But I repeat, you have never proven this, so it reasonable for me to think you are assuming it. – I think you assume it because it is so plausible, as already stated (one reality , one tick rate, hence Aa = Ab)[/qluote]

I don't assume it. I state it as a fact of our accepted physics and mathematics at the basic level. You claim UT doesn't exist in spite of the solid derivation of its truth in favor of supporting an idea, a theory, simply because you have not found (even though yo have not been looking) an alternate explanation. At least your explanations should not violate basic physics principles that we also accept. It does.

I really wouldn't care if it were real. It is tantalizing and fun to think of all the bizzar tings that it jpredicts but unfortunately life is to short to spend chasing fairy tales.

Tell me why I am not justified in thinking it is assumed when you offer no proof that it is fact and yet use it as if it were fact, for example in the twin paradox to conclude the astronaut twin is not younger as SR predicts because all his clocks including his heart, all tick on UT, and do not slow down with his motion relative to say at home twin brother.[/qluote]

Because it is simply theory and this theory is in direct cnflict to the definition of "Relative" and the premis in Relativity that eitehr can be at rest and it is the other that is in motion. By what justification do you then come back and claim that one gets preferential Relavistic affects due to constant relative velocity "BETWEEN" TWO PARTIES.?

NOTE: It does take two to tangle. Without the other party there simply is no relative motion and this relative motion is recipocal. If both clocks slow down by the same amounts due to the same relavistic velocities then there can be no net affect between the parties.

If A = B = C then C MUST = A. It really is that simple.

Defend your assertion in the above quote, that you have not assumed UT

I have not. I proceeded via numbered sequenctial steps using existing mathematics and conditions stipulated by Relativity itself. I will not appologize for the fact that to do so seems to dictate that UT and not SRT is the reality which leaves SRT relagated to be merely perception.

Not so. This is your rendition. I want to see you refer to my sequence as presented, by my number and not respond to your own version of what has been proposed. Yours is so full of holes you couldn't catch a bee in a bee hive.

If you can find something wrong with this post, please let me know.

Well for starters you base our rejection on the absolute ludricrus assertion that to encode the carrier beams with side band modulation transfers no information. Yet you fail to show how that is true. You are making AD HOC FIAT declarations which simply are not factual.

If t1 in t2 = t1 ( 1 - v^2/c^2)^.5 is valid then information about t1 is transferred.

Nothing more to see here, people... Move along please!

Fine but let the record show that as yet none of you have taken the challenge to actually address the presentation number by number and to give any supported claim of error.

Its OK to admit that you cannot. But it is not OK to think you can walk away having done a lot of hand waving and making AD HOC FIAT declarations believing you have somehow proven your objections.
