I really want to share this with someone, I know how to create time travel, but before that, there is some messed up stuff, k have a theory of how the bing bang might repeat, like a cycle, anyways, to create time travel, you can simply get a rocket ship, that goes fast, really fast, like speed of light fast, then you go a distance away and come back, what might seem like a day for you is like 100 years on earth, thus you traveld to the future, but there might be a possibility of backwards, there are separate dimensions, if someone went back in time, everything can. Change at any second, it's really confusing, but yea, tell me if your interested, another thing is, look this video, it might explain a lot, https://m.youtube.com/watch?v=eGguwYPC32I and for fun https://m.youtube.com/watch?v=M4M6wlBjU38
