For example, if you travel at .865c for 1 hour, you age one hour, while everyone else on earth ages 2 hours. But if you travel at 10c for 1 hour, you age one hour but everyone on earth ages .. I don't know the math :) But I'm sure it's somewhere around 10 hours?

Obviously this is science fiction, but it is fun to talk about nonetheless.

Continuing, in Star Trek we learned that people in the future wear spandex uniforms and that they can travel at warp speeds, which are, I presume, great multiples of C.

So if you were to travel a great distance at a warp speed, but in a very short amount of time, what would the effects be? On initial thought, it seems that if you travel for any significant amount of time at a huge multiple of c then anywhere you go will be so greatly aged by the time you get there that your trip there would be pointless.

When I think of this in my head, I see it as the guy who took Einstein's equations and used them to think up black holes, although that was an original thought and I'm sure what I'm writing about has been covered before somewhere else.

So does calculating the gamma factor, with the 1/sqrt(..whatever) equation hold up when using multiples of c, instead of fractions? If I wanted to put in some figures to test my ideas with different values in the above paragraph, what simple equations could I use?
