Brian Cox said something on TV last night..

He said that if we could travel near the speed of light (.99c) then we could get anywhere in an instant. 

What's the science behind this? He didn't explain it. 

Cheers.

Taken literally, that's way incorrect.

However, as you travel near the speed of light, time slows down (relatively speaking, of course). Travel fast enough and years could pass outside your spaceship while you experience hours or seconds. So, in other words, while it would seem like a short time *to you* (and anyone else in your frame of reference), it wouldn't be.
