Easeupyo says that time doen't exist, I disagree. If time didn't exist then every thing would happen at the same moment (I was going to say at the same 'time' but thought better of it ) which would mean you were born, lived and died in an instant (but then without time there would be no instants would there) so you couldn't have posted the message that I just read.
Some famous scientist (I can't remember which one) spent most of his life proving this fact by treating time as another dimension and his work layed the foundatin for much of Einsteins famous theory (you know that one involving E m and c).

P.s. I believe that zero times infinity is 0 cause no matter how much of nothing you have you still have nothing (however it's not something I'd like to prove).
