time travel

Have you ever wondered about time and how it works. It is crazy and confusing on how it works and people say so much about it. The first man\woman to right about time travel was H.G. Wells. Wells speculated that you could travel to the future and back to the pass. Wells might have been correct when Albert Einstein showed everyone his equation E=mc². "We have a hard time perceiving how time can bend just like other dimensions, so Einstein's predictions seem strange," said J. Richard Gott, author of the book Time Travel in Einstein's Universe and a professor of astrophysics at Princeton University. "But this appears to be the world we live in. Einstein said that time and space are link as one. They are linked in what we call the fourth-dimension. The faster you can go slower time moves. Mass can affect time as well. These thing don’t effect time in a big way just in a small way. Right no time can only go forwarded and not back. If you want to go back in time then you must leave a time machine on. so if one does not exist then you can't go back in time. 

 if you build a time machine that can seen you back that would create a paradox as soon as you enter that time period. Are paradoxes even real, What if you travel back in time and make your grand father disappear will you disappear, will that create a parallel universe or will you become a walking paradox.  All this sound crazy but there is science supporting all this, this is no longer science fiction, all this might become a reality.
