Warping through time

  1. Aug 11, 2005 #1
    I went to a physics conference today and there was this speaker who mentioned that if we want to get to the future(eg: year 3000), we could simply travel anywhere using the speed of light and travel back to wherever u belong and u will get to this "somewhen"<not somewhere> in the future.

    Just wanna know, how true is this statement? Anyone who can give an explanation out there?

    You can't ever reach the speed of light, but by getting in a spaceship and travelling at a high rate of speed, you can achieve the same effect. This is known as time dilation. See any of the gazillion threads on "The Twin Paradox".

    This time dilation.. is it due to gravity or are there other reasons that cause this effect?

    Time dilation does happen due to gravity but also simply by moving, but you would only see noticeable effects if you where moving at a significate portion of the speed of light.
