What do you guys think of UFO's?

The basic substance of every organism known to man.


Anyway, I've said this a million times - the laws of physics are constantly being revised, it may turn out there is a flaw in Einstein's law, or there are loopholes. Remember, a thousand years ago we thought that you couldn't travel out of this earth without an angel guiding you, imagine how different our laws of physics and technology will be in a thousand more years. And I don't think we will find a way around the speed of light, at least for a millennia or two.

Yes, indeed, but we can't say that we MAY discover something just because we would like to. At some extent we can explain how the universe was formed which means that we are on the correct truck and we unsterstand physics quite well. To our current understanding there is almost no chance an alien could reach earth.

Tip1: Relativity predicts some hypothetical particles which can travel FASTER than the speed of light with 2 conditions:
1.)They can't slow down below the speed of light.
2.)They are travelling towards the past. Their past is our future and our past is their future.
