An elementery question that probably shows how little I know: If we can't see past 14 billion light years because the light hasn't reached here yet, does't that mean the univerese expanded at a speed greater than the speed of light?
Actually, if we see something 14 billion light years away, that means that 14 billion years ago, it was already that far away. Even at the speed of light, it would have taken that long to get that far away, so the age of the universe ought to be twice that.
But cosmologists say, based on dating stars and such, that it isn't . . . so they theorize a period of "inflation" right after the Big Bang during which the universe expanded at superluminal velocity . . . but since space itself was expanding, it really wasn't faster than light at all . . .
