MaximT Posted January 16, 2020 Posted January 16, 2020 What will be the step to verify relativity in constant acceleration between earth and proxima centory ?

What is the advantage of attempting to do that? One of the postulates of relativity (and physics in general, since at least Galileo) is that physics is independent of place and time.
MaximT Posted January 16, 2020 Author Posted January 16, 2020 What will be the time on the ship clock, if Einstein was wrong, and if He was right, depending on a trip at constant acceleration to or from those two planets? The advantage is to discuss about the theory...

You need to quantify this. What speeds, time, distance are you considering? Better still, learn the simple mathematics of SR so you can work this out for yourself. (And this has nothing to do with Einstein been right or wrong. The theory has been thoroughly tested and is correct.)
Mordred Posted January 16, 2020 Posted January 16, 2020 First off the Lorentz transforms are under constant velocity not acceleration though one can use instantaneous velocity at each coordinate to adjust for constant acceleration. Secondly redshift from distant stars comply with relativistic effects.

In fact, we need proper time, so proper acceleration, because, otherwise, it will be too complexe for me, in time, to discuss that with you, based on Einstein Theory.
Mordred Posted January 16, 2020 Posted January 16, 2020 (edited) Proper time follows the worldline of the light signal. It is the reference clock along the worldline path. Both the emitter and observer is at coordinate time. Edited January 16, 2020 by Mordred

Mordred Posted January 16, 2020 Posted January 16, 2020 (edited) No there is two time descriptives involved in relativity proper time and coordinate time. One must apply each correctly. https://en.m.wikipedia.org/wiki/Proper_time In essence redshift applies in this case as we're dealing with signals along the light path.

MaximT Posted January 16, 2020 Author Posted January 16, 2020 I agree Einstein theory must be apply correctly, if we want to compare it, and verify it...

Mordred Posted January 16, 2020 Posted January 16, 2020 Keep in mind everytime we measure stellar objects and have to account for redshift we are testing relativity. Every time we accelerate a proton at an LHC we test relativity. In essence it's being tested 1000's of times everyday.

Mordred Posted January 16, 2020 Posted January 16, 2020 The Lorentz transforms of SR are easy enough to do at home
MaximT Posted January 16, 2020 Author Posted January 16, 2020 (edited) In resume, that is what we need to verify? https://en.wikipedia.org/wiki/Proper_acceleration Edited January 16, 2020 by MaximT
Mordred Posted January 16, 2020 Posted January 16, 2020 (edited) It's been verified hundreds of times with GPS satellites as one example. Relativity is extremely well tested. Lol they even measured the time dilation between a persons foot to his head. Edited January 16, 2020 by Mordred

I don't want to make you upset, but my personal opinion is that gravitational lines are not conservative in energy, that's why! This clock will do the trick... Edited January 16, 2020 by MaximT

An opinion doesn't have much value. If you are not even willing/able to do the schoolboy math of special relativity, I don't think your "opinions" on gravity and energy conservation have much basis. And what is a "gravitational line"?

Mordred Posted January 16, 2020 Posted January 16, 2020 As a professional physicist I can certainly tell you conservation laws are obeyed in relativity. Though you must apply both the invariant and variant mass. The entire field of particle physics revolves around this principle. Let's put that to perspective CERN fires protons to cause collisions yet the particles they decay into has more mass than the invariant rest mass of both particles. Those particles gain relativistic or variant mass due to their acceleration. All particle decays comply with the conservation of energy momentum under GR. 3 minutes ago, MaximT said: Waste of time, unless you could dilated it to fraction of second.

Now you could close this subject if you want, but It's a big win to me, in a relativistic point of view I don't see how all you posted was your gut feelings with zero evidence. Nothing that changes anyone elses view point. However you can believe whatever you choose. Belief won't change scientific evidence.

If once done they gives rise to evidence… from a hobbys Physicist Edited January 16, 2020 by MaximT -2
Mordred Posted January 16, 2020 Posted January 16, 2020 (edited) Have you even tried any of your claimed experiments ? I have mentioned actual tested and applied experiments that have already been used to test relativity not imagined and never applied experiments. Edited January 16, 2020 by Mordred
MaximT Posted January 16, 2020 Author Posted January 16, 2020 No, but I swear that I saw the results personally, If you know what I mean! -1
Mordred Posted January 16, 2020 Posted January 16, 2020 I'm suppose to take your word you saw a test of proper acceleration between Earth and Alpha Centauri ?
MaximT Posted January 16, 2020 Author Posted January 16, 2020 I have to leave, see you next time, in a year, maybe 🥰. Yes... -2
