If only we can stop the stupid wars and spend all that money on space exploration, just imagine where we could've been already...
Ur anus :P
(ok, that one was way too easy ^_^)
Well, actually, that'd be it. Maybe Pluto, but that's not a fully compatible planet anymore these days. I don't think that all the war-money we've spent so far in history would be technically enough to visit, say, another solar system where there *may* be some sorta lifeform. (which is somewhat of a goal, there's hardly any fun in just getting onto another round rocky ball with dust 'n rocks).
