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.

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 backward in time synchronizing entangled particles over distance.
- pontus 5y agoReally interesting article! I just read the first few pages but it seems like a really interesting approach. Thanks for sharing. I'll be reading it more carefully over the next few days.

- officialjunk 5y agoIn case you didn't know, Physicist Richard Feynman proposed the idea that positrons could be electrons moving backwards in time in his paper "The Theory of Positrons." He even takes it further to say that it could be that there is only 1 electron in the entire universe and it is traveling forwards and backwards in time to appear in the positions of all the electrons and positrons.
