- how can u travel into past(6 votes)
- We cant. There is a way to go to the future, being faster than the speed of light, but unfortunately we havent figured out how to do that. There is a way to see the past though, going far far far out into space and bringing a telescope you would be able to see whats happening on earth at that time. Say we want to go one million years back in time well we'd have to travel hundreds of light years to be able to see whats happening on earth at that time.(2 votes)
- So, ASSUMING you'd be able to travel into the past -- ASSUMING key word -- wouldn't you eventually just break spacetime itself? I mean, if you go back in time, wouldn't you end up making more of yourself come back as well? "Paradoxical effects," as the guy put it?(2 votes)
- that is true but like kursaget said 'your birth,death and life COULD be happening at all at the same time(1 vote)
