I read One of the theroy's in time travle and i've decide that it is possible yet if you went we would never know about you agin in theory we would go back to fix our world where we screwed up and when we came back we would not be in the place where left we would only exist in our own selves beacause we would of not been born our parents never met and if we did exist it would be in history for the people that saved ou world . And when we came back we woud have no history of our selves as in birth cericate in close never born beacause on that reality we never lived your family was never born and rleitves never existed the only dimsion we lived in would wonder what happend to us and why nothing changed why it was still the same and we must be lost in time when in truth they would be.

One more think they broke mach one in a car a while ago just imagine that you would no be able to listen to the radio you would be move to fast for the music think about it ,it will tripp you out.
