"Time Travel"

Mmmm, if time travel was possible, wouldn't we already know how to do it? If it ever became possible, surely someone would have already came back and given us the solution? After all of the tradgedies and wars of this world, surely someone would have felt compelled to do something to prevent these things? Just a thought....

It's only time travel in terms of our own measuring of time. We initally used the sun and moon positions to figure out time. Any differences in distance from either sun or moon, or earth for that matter, and you won't be able to properly use our own time scale in reference. So what may seem like 5 space years, is actually 10 earth years. They're exactly the same amount of time, but due to the distance between all the different parties (the twins, sun, moon, earth) when calculated in each place, the time seems different. If you took a sort of 'life' stop watch, and sent one twin into space, and the other left on earth, started them the exact time, took off for 5 years and came back, they're going to be exactly the same no matter where the space twin had gone.

What a bizarre universe you live in.

It's true though.

Smedders is talking about time dilation. You appear to be suggesting its a matter of perception rather than a real phenomenon?

I think the twin-theory shows that things compared on our own time scale have differences. Therefore some sort of time event has happened.

I'm sure it is possible, just as what's been said, it won't be accessible in our lifetimes. But that's the joy of my interest - stuff that doesn't seem possible has been witnessed, so therefore must be possible... Just with this particular topic, physics seems to be able to back me up!

That's exactly what I'm suggesting :)

Hey, nothing's been entirely proven or concluded. I could be near to the truth :P

Sonic Chris or Einstein...who to believe....tricky :P

Sonic Einstein, the greatest species in the world.
