if i dropped my sandwich and went back in time to stop myself from dropping my sandwich then wouldnt myself from the future disapear because he had no reason to come back? or would he just stay there and make me split my sandwich with him?
Actually, I believe if you traveled just a few minutes into the past, it would only be you. Not you and your "past self." I would guess this would have to do with the fact that only traveling that little amount would not cause any divergence in worldlines. I think the farther you travel (in the past and in the future), the more probability there is that things are going to be different. Maybe Timedrifter can correct me if I'm wrong--I don't know that much about the subject, I've just heard this before.
