Cody Stewart @CODYMAC (1356) • San Diego, California 26 Feb 12

Ok, up until now I have had responses like, "what does this have to do with?" and, "your math is BS". So, now, with the help of the multiplication chart, we will see where this is going. Pi does not equal what science says it...

If we are traveling at the speed of light, what will we see? Will we see anything at all? Or will everything look blurry?

Is the speed of light in space equal to time?

damned_dle @damned_dle (3942) • Philippines 10 Aug 10

Imagine this. If we put a gigantic mirror on outer space, about atleast a light year away, will we see our past? I tried googling this and didn't find anything about it. LOL.

Theory: Do thoughts travel at the speed of light?

commanderxo @commanderxo (1494) • Canada 10 Nov 09

Well...in a "sense", I believe they do. Here's why. We are all familiar with Einstein's Theory of Relativity...E=Mc2... Energy (E) equals (=) mass (M) times the speed of light (c) squared (2). Since thought is an energy...

If it was possible, we travel at the speed of light towards the side of the universe. After many many years, we reach the side. Do you think that it is possible to travel outside of our universe? After all, a theory states that...

socorban @socorban (650) • United States 22 May 07

It baffles me that "light speed" and "light years" are still terms used in measuemets of distance in and outside our solar system. Using these terms assumes the speed of light is constant and un changing when it in fact is not at...
