Is There Experimental Evidence That Contradicts Time Contraction Predictions?

Click For Summary
SUMMARY

The forum discussion centers on the validity of time contraction predictions in the context of Albert Einstein's Special Relativity (SR) and the Lorentz equations. The user proposes a modification to the Lorentz equation, suggesting that time contraction may be underestimated at high speeds or distances. However, the consensus among respondents is that no experimental evidence contradicts current predictions of SR and General Relativity (GR), particularly in high-speed scenarios such as those at CERN. All existing experiments support the established theories of relativity.

PREREQUISITES
  • Understanding of Lorentz transformations and equations.
  • Familiarity with the principles of Special Relativity (SR) and General Relativity (GR).
  • Knowledge of high-speed particle physics, particularly in relation to experiments conducted at CERN.
  • Basic grasp of the concept of time dilation and its implications in physics.
NEXT STEPS
  • Research the latest experimental results from CERN related to time dilation and particle acceleration.
  • Study the Lorentz transformation equations in detail to understand their derivation and implications.
  • Explore the relationship between speed, distance, and time in the context of relativistic physics.
  • Investigate the historical experiments that have validated the predictions of Special Relativity and General Relativity.
USEFUL FOR

This discussion is beneficial for physicists, students of theoretical physics, and anyone interested in the nuances of relativistic physics and the experimental validation of Einstein's theories.

Question on the Lorentz equation on the time
I have another question linked to the equations of Lorentz:

The Theory of the Special Relativity (SR) of Albert Einstein comes from the equation of Lorentz and we have the following equation on the time t’ in the moving frame:

The “space time” (x’, y’, z’, t’) is moving at a speed v measured from the “space time” (x, y, z, t)

t’ = g . (t – (v.x)/c^2)

In the Lorentz equation on the time t we have the speed v of the moving object defined by v = x/t

If we write x = v.t we have the following equation: t = g . t’
and this is OK with the equation of the Theory of the Special Relativity and proves that the SR comes from the equations of Lorentz: the time t’ inside the moving object is the contracted time.

And this result is due to the fact that we have for Lorentz x = v.t (see above), or v.x = v^2.t

The speed v defined by Lorentz is the distance measured from our Earth for example (the rest frame) divided by the time measured from our Earth (also the rest frame) which is t. I have used the term “measured” 2 times because the definition of the speed is using “measured values”.
On the rest frame (our Earth for example) we measure x for the distance but we see x’.

But when x becomes very high, maybe what we measure is perhaps what we see and we will see a contracted distance from the rest frame (x’), but we measure always t because we see t in the rest frame and so the speed will become v = x’ /t = vnew

And so x will be replaced by x’ when x will become high, which is the same to say “when the speed v will be high” (indeed, as x = v.t, if we have a high speed v, it is the same than to have a high value of x).

And so, in the Lorentz equation on the time t, I will replace x by x’ when the distance x will be high, and I will replace v by vnew and so:

v.x will becomes vnew . x’ = (x’/t).x’

And x’ = x / g indeed, x’ is the contracted distance

And so vnew . x’ = ( x / g )/t . (x / g ) = (1/g^ 2). x^2. (1/t)

If I replace t by (t/g^ 2) in this equation I will find:

vnew . x’ = (1/g^2). x^2. (g^2/t) = x^2 / t = v . x (for Lorentz, v = x/t )

And so, as I don’t want to change the Lorentz equations, in order to have vnew . x’ = v . x , I have to replace t by (t/g^2) = t . (1 – v^2/c^2)

As t = g . t’ , if t is replaced by (t/g^2) , t’ will also be replaced by (t’/g^2) = t’ . (1 – v^2/c^2)

t’
for Lorentz is the time at the level of a moving object and t’ will be replaced by the following relation when x will be high or when the speed v will be high:

t’ -> t’ . ( 1 – v^2/c^2 )

And this could be the new relation of the time contraction t’ at the level of a moving object, function of its speed v, when parameters go towards the limits (high distance x, high speed v, …)

But near our Earth, the SR and GR are the only correct Theories. This can be explained by the above points: indeed, near our Earth the distance x is too low and if the speed v is also too low my “Theory” will not be applicable and in the equation of Lorentz we cannot replace the distance x by x’: and my coefficient defined before ( 1 – v^2/c^2 ) will only complement the GR and SR when parameters will go towards the limits (high distance x, high speed v, …).


And now comes my question
: Is there somebody who knows an experimentation where the results show that the contracted time inside a moving object should be more than predicted by the SR and GR ?
For example near our Earth but with a very high speed like particle acceleration at CERN, or … ?
Or an experimentation done at a very high distance from our Earth, like deviation of light or shift of frequency or ? …

I don't know where to begin with this. You look to be in desperate need of a decent textbook.

Who needs a textbook when you're overturning mainstream theories?

Ignoring the correctness (it isn’t) of doing this, you have not properly motivated replacing x by x’ so this is not even an interesting argument.

Anybody who doesn't want to be laughed out of the room when they say that's what they're doing, I would think.

No. All current experiments agree with relativity even at very high speeds. For a detailed review see: http://www.edu-observatory.org/physics-faq/Relativity/SR/experiments.html
