: : : : : Okay, here's my question. Can anything with mass travel up to the speed of light. : I believe I saw this on the discovery channel, that is why I am asking. There they said : that anything with mass could not travel at the speed of light. I just want someone : to verify if this is true or not. Thanks, : Light Star : : : : : : : : : Hi there. : : : : : Can anybody explain me why we go beyond the light speed.

: : : : : Thanks.Bye.

: : : : What do you mean???? Beyond the light speed???

: : : : If you mean why do we not stop with light as the fastest speed that's because light doesn't travel at the same speed. It all depends on the median in which it is traveling ie. water, air,space.

: : : :Since light has no intrinsec mass,it would take an infinite amount of energy to reach its speed (according to Einstein's E=mc²),and your mass would then become infinite.Moreover,if you could go faster than light speed in the vacuum(300 000 km/s) ,you would run time backwards.

: : And technically, your mass would be infinite. Therefore, you would be at every point in the universe at the same time.
