- TL;DR Summary
- Time travel to the past appears impossible due to the inevitable paradoxes. However while contemplating whether many worlds was in fact metaphysics, it may be a solution to the paradoxes.
And also an answer to 'where are the future time travellers?'. Let's say hypothetically that in the future time travel into the past is invented. To me many worlds looks like metaphysics, but it appears to be taken seriously by physicists, therefore, what if after traveling backwards in time as the traveller arrives could we postulate that his arrival creates a many worlds split so that person is now in that timeline so whatever happens does not affect the timeline whence he came?
