Hi All

I'm a newbie, so please be patient.

A few friends and I were discussing the concept of the ever expanding universe. We were somewhat perplexed about the nature of an ever expanding universe. What is causing the expansion? Is it the force of the Big Bang, or is something else (some other force) driving it.

I made the point that, if the universe was indeed expanding, then, by definition, it wasn't actually expanding into anything, as that would imply that there was something other than the universe into which it was expanding (hope you're getting this). My point was that as the universe expanded, then it was creating void, but that it couldn't be expanding into a void. A void is something....well the lack of something....which amounts to the same thing. So the universe is expanding, but not expanding into anything.

Am I on the right track, or not? Sorry to land this curly one on you all as my first post, but it's an intriguing question.

Thanks.....John.
