At least when you think of objects moving slower than light there can't be reversing of casuality. But relativity allows for that, we just drop the faster than light solutions usually as non-physical. Recently there's been an interesting paper about what happens when we don't drop these solutions: https://arxiv.org/abs/1910.02780 Imagine the Andromeda fleet can move faster than light. When you look at it from Earth POV suddenly it manifests near Earth out of nothing. Looks very similar to quantum mechanics indeterminism - if alien general decided to send the fleet it's there, if he didn't…

Recently an interesting paper came out that starts by accepting all solutions to special relativity (usually the faster-than-light solutions are ignored) and goes on to derive the axioms of quantum mechanics from just that. It turns out what you need to prevent timetravel paradoxes is exactly quantum mechanics. https://www.eurekalert.org/news-releases/540753 https://arxiv.org/abs/1910.02780 I don't understand the whole derivation (especially the way they move from 1+1 to 3+1 spacetime), but it feels quite elegant. It could be interpreted as universe having a separate family of particles going…
