What exactly is an expanding universe?

If one gives credance to the big bang theory, there definitely was, in the first nano-second of the universe's existence, points of space in the universe, that were moving away from each other at much more than the "c".

And these points in space could have been occupied by particles which would have been moving away from each other at speeds much higher than the speed of light. Such a situation, apparently, would not contradict the special or general theories of relativity.

I don't know why. I am not a physicist.
