: It seems as though all you master minds have it figured out, but here is something you forgot to consider: If there is another life forum out there and they are 400,000 light years away from earth,they would have had to of left there planet at least 400,000 years or more ago to reach the earth unless they are able to travel faster than the speed of light in space. If we were looking at there planet 400,000 light years away today, we would be seeing what happened 400,000 years ago.So if this UFO sightings are real, the they must have come from somewhere pretty darn close. I think it's really interesting to read how everyone knows all about this traveling faster than the speed of light in space,yet no one has been able to accomplish this great feat, so they take the easy way out and say it is impossable...! : : : : : : : 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=mc˛),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. : I would like to know how does relationship between mass and speed of light change. I would like you to show me that through mathomatical explanation. Please show me how this is done through algebra.
