@Surasanji Obviously information was created/discovered at first by Einstein et al. Then it passed over to you and you used time travel to push the time of creation/discovery backwards. With time machine, timeline of events cannot be set in stone in the way we think history is.
I have a scarier version : Suppose you time travel back and convince the inventor of time machine not to invent the machine and the time machine that you travelled back in time with was never invented. What happens to you after that? What about the machine? How is it even there without being invented?
