I have to add that people that travel into space at high speeds actually time slows down for them... So I think it was einstien that thought of this but Im not sure.... Apparently, the theory is that if you travel faster than the speed of light its not impssible to go back in time but nobody has actually done that yet.... Its not impossible and there is evidence backing that theory up.....
some1 said that, sorry, i fogot who. Yes, it was einstein, and its called the "theory of relativity". Learn somethin new everyday.
Now, who was it that said they didnt read what i said because of poor grammar? Ha, as far as ive noticed i have better grammar skills and diction than some people who replied.
A clock isnt a time machine, its a machine to measure time. However, because like us the clock is always travelling into the future, i guess it could be considered a time machine. So by that logic, any machine is therefore a time machine. Just think, im typin out this reply on a time machine.
Crack is whack =D
Cher, ha! hahahahahaha

errr, i guess sorry if you like cher, but i find it hilarious that what she "sings" could possibly be considered music
Maybe one more thing. Someone said i should have posted this in the philosophy section, well, read all the replies, this topic went from time to time machines to vaginal creams to canada to cher. Not exactly philosophy now, huh?
