According to this:

The matter was already there, the Big Bang just caused it to expand.

Ok, I've read that. Far easier than I thought.
What this says (answer 6) is that it's possible the the speed of
expansion can exceed the speed of light !!
In a way I can sort of see that working. If nothing with mass can
move faster than the speed of light it seem only reasonable that that
nothing (having zero mass) CAN move faster than the speed of light...

The way I read it, it only appears to be travelling faster than light.

I think I might have to go for a lie down in a darkened room for a while
now...

Or one filled with light! :-)

What gets me going, is if the universe *is* a universe, by definition it
must be infinite, surely? So how can it even have a size?

But, surly it's only infinite because space is curved. If you could
somehow measure a straight line without the curvature getting in the way
you might find the 'edge' ??

No, I just think, as humans, we can't comprehend 'infinite', so have to
try and put limits to the universe.

After all, nobody really knows all the answers, we can only go by what
is known at this time.
