If I travelled back in time to when I was younger wouldn't that mean my younger self would have already seen my current self as I'd have already visited from the future? (lemmy.ml)

So I’d have already seen my self travel back in time and am just repeating what’s already happened. Which would mean I’d have already seen my current self in advance and am now just experiencing the same event from the other way around?

This is a physics question. But the current laws of physics do not allow for going backwards in time, certainly no way for anything to interact with a past version of itself, so even if, IF it was possible under some future model that will replace the current one, there's no way to predict what would happen with the current model because the current model says it doesn't happen.

It's like asking pre-Copernicus physics to calculate the movement of different star systems around a galaxy.
