Convincing you is the least of my worries. And what you believe and say is not in question: What is in question is your belief that anyone is taking you seriously.

SR/GR have stood and continually passed all tests [including length contraction] thrown at it. It is not going to be invalidated or derailed by any amateurish attempts on a science forum.
Time dilation and length contraction can be said to be somewhat interchangeable:
It can be said that they are two ways to describe the same effect. The Lorentz transformations are the reason of both effects.
You have had that already pointed out with the Muon experiment and observations.
You have the scenario of the muon's clock running more slowly than a muon's clock on earth at rest, due to its high near "c" speed. But likewise you can also view in the muon's FoR, that the earth's atmosphere is length-contracted.
The choice is your's......I prefer science, the scientific method and peer review to unsupported pseudoscientific nonsense.
Your presumption's are astounding, where in this thread does it mention that I am here to derail anything? I have questions and people gave answers, I asked for hard evidence and got replied to with more word salad. You are claiming the object itself contracts, I asked for the evidence, is that to hard to understand for you?
For James -
Analogy - Imagine observer (A) is standing on a train station platform, either side of the platform is a train, train (B) on the left track and train (C) on the right track, each train consists of five, fifty feet carriages.
Observer (A) measures both (B) and (C) to measure each train is 250ft in length while at relative rest length, relative to the stationary inertial reference frame of the observers.
Both trains start to accelerate at the same time at the same rate, both moving in the same direction away from (A) who remains relatively ''stationary'' to the reference frame of the platform. Observer (A) experiences the visual length contraction of both trains, each carriage decreasing greater in length the greater the acceleration.
However, observer D and observer E are on each train, they both are sitting in seat X, which is exactly the half way point of the initial measured rest length. Both observers D and E observe 125ft either side at rest length, in parallel motion both D and E still measure 125ft either side , relative to each other.
james replied - ''I guess the point to make here is that there is no preferred reference frame in relativity.
The trains in your example are both stationary relative to observers D and E, so those observers see (measure) the rest lengths of the trains.''
I agree totally
My second scenario -
''It took me a few hours of thought to give you an answer you asked for. You asked for a test to distinguish between a real contraction and an illusionary contraction . Now I have had a think , it seems quite simple really .
An observer stands in the center of a circle. Around the circle is a circular train track, on the track is a train that's length of carriages and engine is equal to the circumference of the circle, the train starts to accelerate around the track , relative to the observer , the circle is constant
Even simpler, a train is stationary a mile up the track, down the track, an equal length train is about to come speeding past, when the front of the speeding train is level with the front of the stationary train, the rears should align .''
I can only conceive from this that at an exact moment, both trains will align and relative to each other , measure the length of each other as if at rest length and being the same and equal length.
