On several science threads, people posed the premise that Big Bang inflation violates relativity. I could only respond vaguely that it doesn't. I stumbled on this NASA site this morning and they claim inflation works fine with relativity because causality is not violated.

But special relativity was not violated, because this was an expansion of SPACE and no matter or information was carried between two points at faster than light speed.

Is there some parts of space that have ... no matter?

interesting... always been a huge question for me, so thanks!

If space itself expands, then since matter isn't moving through space, it doesn't count? Is that it? I've never understood how this inflation didn't violate everything like crazy, actually. It's always seemed very ad hoc to me.

Now I wish someone would explain nonlocality to me, and tell me why, if it's true, we can't send signals infinitely fast.
