Hey thanks for your answer. I'm not looking to argue what the sun is made of, and trust me I'm not trying to prove that you guys or physicists in general are wrong. Please be patient with me because I take this thread very seriously(I've been ignoring my customers for the past couple days just...

Yes particles would carry an imprint of the past history of their motion, and yes the particles from the exploding nova would be shorter than the ones on Earth but how would we know? The only way to observe it would be to go get some of those particles around that exploding nova and come back to...

Hey phinds thanks for your answer, I completely agree with you, but what if everything in space does fluctuate in size but it would be difficult to observe because every observer and their surroundings within a inertial reference frame would fluctuate in size proportionally with respect to...

Hey Dale, After doing some research on born-rigid motion, this is what I understand it asks, correct me if I'm wrong : What acceleration profile is required by the far end of rod X (the end closer to point B) so that the distance between both ends of rod X remain constant in their proper frame?

Again sorry about not being very clear, I didn't mean objectively at rest, I meant at rest from the observer's perspective. Thanks

Thanks for your answer, would you be able to explain why? Or provide some proof of that statement? Thx

Sorry about that let me rephrase: Once the odometer and clock are in the same rest frame as the "observer at rest"

Thanks for your answer, I understand that the recorded traveled distance would permanently show less distance traveled, but would the length of the clock and odometer themselves be contracted permanently from the perpective of an observer at rest, after the event once the odometer and clock stop...

I guess it doesn't really matter who's perpective we take, the particle or myself, is our length proportionally equal before and after that particle moved in CERN? Thanks

When that particle stops moving, will it's length (relative to mine) be the same as before it started moving?

Thanks for your answer Dale, I'm not familiar with the term Born-rigidly, I will do some research on it and get back to you.

Lorentz contraction problem: By Bertrand Boucquillon Components of the problem: - Bob (observer) - 2 identical rods that both measure 1 meter. Let's call them rod X and rod Y - Point A - Point B Scenario (step by step): 1) Bob is at point A, and is at rest with both rods in his hands 2) Bob...
