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.

Ask Buzz Lightyear

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!!!
