I'd love to know what happens as you near the speed of light - I don't think we could exceed it. I mean:

Say you are driving your car down the street at 30 m/s... your headlights are on - the light emitted will only travel at the speed of light, not the speed of light + 30 m/s. I read up on the theory of relativity, it was crazy, the faster we are traveling in an object, the slower time is actually moving in said object. So say you were in a space ship flying past the earth (at half the speed of light), if you had a set of binoculars powerful enough to look into the spaceship, everyone inside would look like they are moving in slow motion (at half speed), because the light has slowed down inside the craft so it cannot exceed the speed of light... weird eh?
