Talk:Ladder paradox

What you talkin about Willis
How can switching meaning from constant velocity to acceleration explain what goes on when the ladder or barn are not accelerating? Is this not a special relativity representation at constant velocity with no acceleration? An explanation of what happens when something is accelerating can't describe or explain what happens when there is no acceleration. Where in the explanation is the position of the observers in the barn or on the ladder considered? What they observe will depend on their positions due to finite photon speed. An observer at the back of the barn will observe something different than an observer at the front of the barn. An observer at the front of the ladder will also observe something different from an observer at the back of the ladder.

The problem here is that there is no real experiment with real observables to constrain by necessity. There is no actual experiment and therefore no actual observables. The truth will be whatever it is your imagining! The only thing being proven is that you can imagine or assume how it works because, there are no real observables from an actual experiment that can be contradicted by your assumptions. But there are no real observables that can be used to prove your assumption is correct either.

"(...) the ladder did not need to fit inside the garage."
In the article, it all looks like both referential frames are cancelling each other's length contraction. It should be explained why/how the presented solution does not bring (back) in the next paradox: Michealson's experiment and findings that light doesn't act according to Galilean/Newtonian laws. Aren't special relativity and general relativity theories? We are trying to build new tools to observe cosmologic gravitational waves to try to prove or discard those theories, isn't what a Wikipedia article is supposed to state? That this paradox exists only in the case those theories were proved to be true, and have yet to be? Instead what do I read?... I am disappointed. Even more so because it reflects more the state of mind of (some, not all) scientists than the spirit of the Wikipedia project and community. What tech and knowledge are we missing because of so much denial? :( 80.215.94.164 (talk) 22:22, 15 October 2022 (UTC)

See https://phys.uri.edu/~gerhard/PHY331/lam23.pdf "Skater paradox" In short: If relative speed is high enough the events: - back end of rod meeting back end of hole - front end of rod meeting front end of hole can not be casually related. Johanwiden (talk) 11:39, 30 June 2024 (UTC)
