I was thinking cause i was bored..
Time travel is not possible
Say you wanted to make fast cash so you went into the furutre say 100 years.. find the most usefull tool there that wasn't in your time.. you go back market this thing and make alot of money.. but would the item dissappear... because if you took it from some one that invented it and brought it back then it would have already been invented so that means you could not have seen it there?!?!? Thus you dont have it cause it wasent invented cause it was already there?????? i just confused myself.
