B Is perpetual motion a forbidden topic in the scientific community?

[robotkid786]

TL;DR Summary

If perpetual motion is impossible doesn't that mean that the universe has a definite beginning and end?

I've only just clocked this to be the case. I asked chat gpt and the say big bang has a lot of merit apparently

No. Supposed perpetual motion machines always lose energy to somewhere, which is why true perpetual motion machines are impossible. The universe is all there is - there is nowhere for it to lose energy to. So your analogy is flawed.

Do not trust large language models on physics. They are trained on the internet and there is way too much misinformation and not enough maths.

Huh? I think perhaps you misunderstand what a PMM is. Your statement is a non-sequitur.

(1) Yes, but it only says that because it is true (although it is an understatement). You possibly don't really understand the Big Bang Theory either.
(2) Do NOT use ChatGPT as a reference here. The moderators have decided (rightly I think) that it's not appropriate. It makes too many mistakes.

ChatGPT is not a valid reference here.

PMMs are a forbidden topic at PF (for obvious reasons). Please follow the Insights Article link in the rules quote below for more information. This thread will remain closed.
