And I would like to know,

If the universe is always expanding, what is it expanding into?

It'll be a while before you get an answer to that one... try typing "string theory" into google and that'll keep you busy for a few months!

So the dark matter evident in our universe has leaked in?

The Universe is infinitely large, so it doesn't expand into anything. The expansion is merely the fabric of time stretching in between everything in the Universe. So everything effectively gets further apart and hence the appearence that the Universe is expanding.

How do we measure infinity in order to know that. Just because our primitive technology can't detect the edge doesn't mean there isn't one.

There is no proof that the universe is infinite... at least not in my Haynes manual!

How about this for a curve ball.... multiverses!

not only do we not know what our universe is or isn't expanding into or not into, Mr Deutsch slips in the old Multiverse theory... what the hell are these babies not expanding into?

No, no, it's the matter in the universe that is expanding into the space around it, not the universe itself expanding.

But keep that to yourself. :alien:

actually it is not expanding at all - it just looks that way. the universe is in fact shrinking.

By his very nature, man tries to explain things in terms that he already knows...nothing is infinite, apart from the moaning ability of my ex wife!!!
