now let's talk logic.
according to einstein, it is possible to time travel.
well i am here to refute that assumption.
ok so time traveling is possible ( initial assumption) // follow me on this one please.
so you go back in time.. right? okey so you still have recollection of ur initial present, or the future of where you are now. so basically you know everything that is going to happen "next". so u didnt really go into the past since u are tied to this future.
now lets go the other way
so lets assume that you went back in time, and subsequently u dont know anything anymore about what happened next, in other words, no recollection...
so you dont know you did, so basically, u didn't, did ya?

also,
ok lets assume i went back in time let's say 2 years.
so i go see a friend. paralel to this, this friend is evolving in 2008.. how can he have 2 presences paralel to each other ?

you see, time is a very simple fact. time is not a value that you can change, zero or even reverse, time is the chronological sequence of events.
any certain event happens because of the one before it who through logic also happened due to the one before it... etc.
so basically, u cannot change something that already happened. supposing by some sci-fi technology you are able to recreate the same "world" of a moment in the past, it is merely a copy, and it is your future, who's a clone of your past. for example, if you recreate the year 2006 now, it would be the year 2008 as a clone of 2006, u didnt go back in time, since 2007 happened before this image of 2006... u only recreated it.

sorry if it was too complicated, but i do believe that einstein was a smart guy until he came up with the chronosphere thingy. **chronosphere: time travel machine**
