Something very interesting whenever this question is asked - what is the speed of light? It is "the speed at which data propagates through space time". I think that is a fascinating truth to our universe.
There is a very good discussion from r/askscience on this topic: http://www.reddit.com/r/askscience/comments/1kjp6z/does_gravity_travel_at_the_speed_of_light_if_the/ http://www.reddit.com/r/askscience/comments/1kjp6z/does_grav...

- mahranch 13y agoI always liked the analogy from here: http://zidbits.com/2011/04/why-cant-anything-go-faster-than-the-speed-of-light/ http://zidbits.com/2011/04/why-cant-anything-go-faster-than-... The speed of light can be thought of as infinite speed in that context. Since time slows as you get closer and closer to the speed of light, it stops completely at 299,792,458 m/s (hypothetically, if you gave photons a reference frame). Trying to go faster than light could be compared to a car slowing down for a red light. Once at the red light, the car stops. Going faster than light would be like asking the car to go slower than completely stopped. It just doesn't make sense in a philosophical or mathematical sense.
