How can space expand faster than the speed of light?
Question asked by: mrquestion

Great question, and one that confuses a lot of people.
Although nothing can travel faster than the speed of light, when space is expanding itself then things can move further than light does in a period of time - this is because it is not a particle that is travelling it is the fabric of space itself.
Space can expand at a rate that has not been determined but should not be expanded to be bounded by the movement of light or particles, so if the fabric of space itself expands then things can effectively be moved apart from each other at faster than light speed without themselves exceeding the limit.
