Hello everyone and apologize if my questions seem a bit off, please have patience with me.
I want to have the following, rather simple, thought experiment.
Let's say that we have a moving object O with the proper length L, when at rest. Let's say that object O starts moving at 0.9c (90% the speed of light).
I would like to know what's your take on the Length Contraction at the relativistic speed of object O? Is it a real length contraction which can be perceived and measured from two distinct frame of references, one from an observer A which is at rest relative to object O and second from an observer B, in a frame of reference which is in motion, traveling with the same speed with the moving object O.
Would both observer, A & B, measure the same length (a contracted length l smaller than the proper length L, l < L) for the moving object O? Or, would observer A measure the object's length as being l (contracted, l < L) while observer B, moving with object O, will measure the object as heaving its fully proper length, L.
My take is that while, observer A will measure the object O as having the length contracted, l, observer B will say that O will have its proper length, L.
Also, please tell me what's your take on Einstein's statement:
"The question as to whether length contraction really exists or not is misleading. It doesn't "really" exist, in so far as it doesn't exist for a comoving observer; though it "really" exists, i.e. in such a way that it could be demonstrated in principle by physical means by a non-comoving observer.
—Albert Einstein, 1911"
Please don't close my topic even if you find my questions a bit ... easy for you or on a different spectrum from the main stream opinions. I would just like to try a different perspective and conduct it as constructive topic to promote growth. I have no intent on trolling.
