The expansion of space has been known since the 1930s, since Edwin Hubble discovered almost all the galaxies we can see are moving away from us. It's also been known since the '90s that this expansion is accelerating, much to the bafflement (is that world?) of physicists, as it really should be slowing down. The resultant concept around this acceleration: dark energy.

That has already happened, but, crazy as it is, these theories have had the evidence out of favor with them. Save for the most extreme cases (i.e. the insides of black holes and the beginning of the universe) relativity predicts everything correctly. When a quantum theory of gravity is formulated, there is no reason to believe that it will show us any way that one could reach superluminal, or luminal, speeds without an infinite amount of energy. Wow, science really IS rapidly growing. | |
Speaking of space, I've heard from my teacher that scientists beleive that space is actually GROWING! Do you people think that's true? (Stay on topic about the lightspeed thing as much as possible while you answer this).
