The power for reaching the speed of light need not be that great.

A solar sail could accelerate a craft to near light speed as the pressure of light pushed against the sail. Its just that the acceleration is so small that it would take a very long time to reach near light speed.

So although I don't think our race will get to develop light speed travel for many 100's of years if we can survive that long, I do think that it is possible.

I don't understand why TIME slows or reverses when you reach or exceed light speed.

The amount of time that passes remains constant right?

If the light from the sun takes 8 minutes to reach you, it does not change the fact that 8 minutes have passed.

Am I missing something?
