Not really. In the context of the twin paradox the return is essential. But indeed "time dilation" itself does not require such a return. Note the twin paradox does NOT demonstrate "time dilation". Rather it demonstrates the difference in elapsed proper times over different paths through spacetime. Consider triangle ABC. One side goes A->B, and the other two sides go A->C->B; the lengths of these two paths between A and B are different. That is PRECISELY what the twin paradox demonstrates, but in a space-time plane. > The experiment in Darmstadt https://arxiv.org/abs/1409.7951 has shown that > the time dilation is instantaneous. Yes. Note the authors claim agreement with SR. > Hence there is no agreement between reality and relativity. You got this WRONG. There is no agreement between reality and YOUR PERSONAL MISUNDERSTANDINGS OF SR. But as this and zillions of other experiment show, there _IS_ agreement between experiments and the actual predictions of SR. > For the theory of relativity it is actually very important that the time > dilation at first is seemingly. I don't know what you mean by this, but it is probably wrong as you got it wrong in other recent posts. "Time dilation" is not a mirage or mere appearance, and it can have physical consequences (e.g. kilometer-long pion beams exist); but it is NOT an actual slowing down of time or of clock tick rates -- it is GEOMETRY. > If the slowing of the time in the reference system of one of the observers is > real, then in the reference system of second observer must automatically > increase the time speed. In this way the relativity principle collapses. You are confused. There is no "slowing of time" in ANY system. What "collapses" are your personal misunderstandings of SR. Differently moving observers MEASURE each others' clocks to tick differently from their own -- this is purely geometry and has NOTHING to do with "time slowing down". That's why I put "time dilation" in scare quotes -- it is a very bad name as it has great potential to confuse people; apparently it has confused you. But it is historical and we're stuck with it. Note that the Principle of Relativity says that the laws of physics are the same in all inertial frames. That means that TIME DOES NOT SLOW DOWN IN ANY INERTIAL FRAME (because that would change the laws of physics). So it is quite clear YOU got it wrong (perhaps aided and abetted by careless authors).

You are looking for an alternate, more classical explanation of a documented observational fact. Unfortunately, your proposal does not match observations. If time stretching were due to motion through a medium, then the time dilation would be single-valued, determined strictly by the relative motion between the body and the medium, and all observers would agree on the value of the time stretching regardless of their individual observer motions. Unfortunately, that is not what is seen. What is seen is that the SAME object looked at by several different observers at the same time will see DIFFERENT amounts of time stretching, and this can't be accounted for by the object's motion through a medium. -- Odd Bodkin --- maker of fine toys, tools, tables

Only one observer at rest has the reference time. By any other moving observer the time will slower depending on the speed. Therefore for different observers the time stretching of one fixed reference system will also be different.

Suppose you have one observer at rest, and there is an object that is moving through the medium at 0.5 c to the east, and so it's time stretching is some factor (I think it's 15.5%). Now you have some second observer that is moving 0.2c to the west and so the time stretching factor for this second observer is 2.1%. For this second observer, would you say the time stretching factor for the original object is less than 15.5%, more than 15.5% or the same as 15.5%? -- Odd Bodkin --- maker of fine toys, tools, tables

So, we stay by real things: http://www.nature.com/nature/journal/v268/n5618/abs/268301a0.html . Let us imagine that the experiment has run like this. An experimentator stood next to the accelerator with a stopwatch, to measure the lifetime of muons. He kept the clock so that the muons could "see" it. The experimentator stopped the clock after 64μs and said "Wow! The time went by muons 64µs/2.2µs = 29 times slower!". Meanwhile the muons looked at his watch. They saw that the clock hand turned 29 times faster. In addition, they could still see that the experimentator stopped the clock at 64μs. For the muons, however, it was only 2.2μs. What could they conclude if they were still alive?

They conclude that every time they pass by the experimenter, his clock has advanced 29 times more than their own clock has advanced between meetings. This does not refute SR, because SR predicts this. Remember that SR's "time dilation" requires a VERY SPECIFIC way of measuring the rate of the moving clock: an inertial observer must use two synchronized clocks to measure its rate. The physical situation above is quite different from that. Stated differently: in SR "time dilation" is a geometrical projection, but in the above physical situation the muons are NOT projecting the experimenter's clock onto their own time coordinate, they are merely observing it multiple times.

In our specific case the experimenter is to observe the slowing of time by muons and the muons as well as the slowing of time by the experimenter.

You claim "to understand relativity", but this clearly shows that you DON'T. In particular, you must READ the Principle of Relativity and LEARN what it says -- it CLEARLY states that it applies only to "systems of co-ordinates in uniform translatory motion", which we now know means inertial frames. Those muons are NOT at rest in an inertial frame, the PoR does not apply. You must also READ my previous post. It explains why "time dilation" does not apply to this physical situation. Tom Roberts

Too bad muon's clocks exist only in imagination of brainwashed idiots. Like yourself.

After all, you're the one claiming that all the relativistic results can be explained without invoking relativity. So you need to examine cases where relativity claims marked differences from what classical physics would normally say happens, and then look at whether IN THOSE CASES, an aether treatment will get the same result as relativity. > > But do you have such a practical example?

Practical tests (GPS) has shown your concept of counting time locally is exactly as useless, as it looked, and even those like Tom or Jan are not stupid enough to treat it seriously.

This sentence does not make sense. I strongly suggest that you learn proper English or post (also) in a language that you are familiar with (this is an *international* newsgroup after all). > How quickly was the time in the reference system of the experimenter from > the perspective of the muons? Mu¹. To understand this you must ask: “What is the time dilation in the frame of reference of the muons *compared to* and *as observed by* the experimenter *in their rest frame*?” Because the key point in the theories of relativity is the *relation* of the same quantities in different frames of reference (and therefore how to properly transform quantities from one frame of reference to another). (So – as Tom Roberts already explained – the correct statement is NOT: “Moving clocks tick slower than those at rest.”, BUT: “Clocks moving *relative to* the observer *are observed by them* to tick *slower than* those not moving *relative to* the observer”.) To answer the right question, you could simply have googled “atmospheric muons” and found, for example: ,-<http://hyperphysics.phy-astr.gsu.edu/hbase/Particles/muonatm.html> | | Atmospheric Muons | | […] | Measurement of muon flux at different altitudes is a useful example of | <relativistic time dilation>. With an energy of 4 GeV, the time dilation | factor is γ = 38.8 . Next time, do your own homework. __________ ¹ <https://en.wikipedia.org/wiki/Mu_(negative)> -- PointedEars Twitter: @PointedEars2 Please do not cc me. / Bitte keine Kopien per E-Mail.

And an observer walking a street observes trees and buildings running around him. Relativistic moron imagined! Relativistic moron simply can't be wrong.

This originally started with “So NOT: …” You have shortened the quotation of my text to make it look like nonsense. Typical. > And an observer walking a street observes > trees and buildings running around him. If you replace “walking” with “sitting in a car”, and “trees and buildings” with observable things that actually could move relative to the ground, you will realize that if the observer cannot realize that the car they are sitting in is moving relative to the ground, they could just as well assume that the things they observe outside the car are moving relative to the ground instead. A better example of this, which is not just a gedankenexperiment¹, but is from real life, are two trains halting next to each other at a train station.² If the trains were constructed so that they accelerate very slowly and "softly", several times I had a hard time figuring out, without looking at the platform, whether the other train had started leaving the station, the train I was sitting in, or both. All I could tell with certainty was that the trains were moving *relative to each other*. Which one was moving *relative to the station* was particularly hard to determine at dawn or night, where from inside the illuminated train you could not see well the platform on the other side of either train, the lights being reflected in the windows. > Relativistic moron imagined! > Relativistic moron simply can't be wrong. I hope for you that will get the chance to observe in your lifetime a situation as I described above, so that you will finally realize that the principle of relativity is one of the foundations of, but not limited to, the theories of relativity, nor merely a theoretical construct, and as a result how stupid *you* have acted in public all these years. ________ ¹ Thought experiment. It is agreeable for me to find so many terms from my native language in scientific English, which of course originated from several German(-speaking) scholars. ² Maybe it is not mere coincidence that Einstein used trains in his thought experiments. -- PointedEars Twitter: @PointedEars2 Please do not cc me. / Bitte keine Kopien per E-Mail.

Relativistic moron imagined! Must be true, relativistic moron can never be wrong. Surely they can assume as well. Steering wheel? Gearbox? Fuel? Ordinary common sense prejudices, refuted by Michelson and Morley. But, tell me, please, which precisely experiment made you an expert in the subject "which assumptions are well and which are wrong"?
