going into the future should be ALOT easier than going in the past
the speed of light is a limit wich is somewhat "impossible" to reach. (from what I remember)
but with technology, we approach is every day
the faster we go, the more time passes slowly.
so if we go @ a speed close to the speed of light we will go in the future, although it will still take alot of "travel time"
finally, the experiment with the atomic clocks
when they put atomic clocks in a jet that went @ Mach3 (I think)
when they brought it back to earth, the clocks were a few milliseconds distorted.
going FASTER than the speed of light, now thats something to think about
Im not 100% sure of what I wrote here, but most of it is still fresh in my head
edit: lol nazgul, I hadent read your post, hehe
