Okaaaaay - so if there wasn't space for the ballon to expand - - - - where is it expanding into?

A common misconception is that the balloon is expanding into empty space that is "beyond the Universe" and that it is expanding from a single point in the center of the balloon.

It's not expanding from a single point. As I said once before - in infinity all points are equidistant from the ends - because it is infinite not finite. The misconception is that there is a limit to the universe. There are no limits - only in their "model" - maybe they need multiple models

Plus an explanation of infinity.

Or maybe multiple ones

Ahhh - I know! Next they'll tell us it's not that the universe is expanding but everything inside it is shrinking making it appear that it's all expanding. Even the measuring instruments and light wave/particles are shrinking all at the same rate so when we measure it of course it all appears to be expanding.

Say that again more slowly!

ah screw it - it would take too long!

The absolute definition of the Universe is

That it is an entity

Which defies logic.

You stand entirely correct.

The universe is not only stranger than we imagine, it is stranger than we can imagine!

Though I cannot remember the origin of that quote.

Definitely heard Dawkins come out with that one, though he may have been quoting someone else. Another favourite of mine is the one about anyone who tells you they understand quantum theory obviously doesn't understand quantum theory.

It's the way I tell 'em.

Huh...thought I posted this link but I guess not.

Here is a series of lectures explaining dark matter and cosmology ins fairly simple terms with minimal maths.

Stop showing off, Monk!

Thanks for that, I find it quite difficult to keep some of this sort of information in my head for any length of time (plus it probably doesn't help that the information itself is often subject to variation) so this was interesting.

Out of curiosity, I've seen all those extra little curly dimensions cited as the home of the missing gravity (ie - gravity seems hopelessly weak compared to electromagnetism because its actually distributed over at least seven more dimensions the four family-sized ones we're aware of. I may have isunderstood the point but this also makes me wonder if dark matter might be something found only in said higher (yet much smaller) dimensions.

I didn't just dream this stuff, did I?
