Also, when traveling at the speed of light the entire universe would appear to have collapsed down to a single point, because of length contraction. So really, the notion of movement or change completely breaks down when you are moving at the speed of light... except in your reference frame were everything is normal. Also, it would take an infinite amount of energy to accelerate something to the speed of light, so the speed of light is a limit that you can never actually reach (i.e. an asymptotic limit). |
