[QUOTE="Deset Gled, post: 5304418, member: 7808"] It's a good description for a sci-fi book. As is often the case with sci-fi physics, the real math gets in the way. The bottom line is that you can't actually travel at the speed of light. If you could somehow travel faster than the speed of of light, lots of funny things would happen, but it is not an actualizable consequence. The equation for time dilation is: To = Tt / (sqrt(1-v^2/c^2)) Where To is time seen by the observer, Tt is time seen by the traveller, v is velocity of the traveller relative to the observer, and c is the speed of light. The key point to notice in this equation is that when v = c, you literally divide by zero. Once you figure out how to do that, feel free to re-write math and/or physics as we know it. A similar problem happens when you look at inertial dilation, as your mass becomes infinite at the speed of light. [/QUOTE]
