I was having a bit of a philosophical moment while scoffing my eggy breakfast this morning. And I suddenly thought "What if our Universe isn't the only universe?" Some people might say that this was a heretical thought - but it got worse.

I couldn't help then thinking that Mankind's smug insistence that "There is only one Universe and that's ours" seems to me to be remarkably akin to the insistence of Christians that there is only one God.

By the time I cracked open my second boiled egg I was thinking that it's a well known fact that scientists admit our knowledge of our own Universe is woefully incomplete. So what is there to say that there may not, or can not, be another (or several other) [or even many other] universes all existing simultaneously? Why is this perceived to be so impossible?

My question is...Why are otherwise reasonably intelligent scientists so rock-solid convinced that there is only one Universe?

If, as scientists continually tell us, our Universe is expanding, then what is there to say that what our Universe is expanding into may not be other as yet undetected regions of Deepest Space already occupied by other universes? Can scientists disprove this line of thought?

Another question...
What if our Universe isn’t actually infinite after all? What if it is finite and other Universes do exist beyond the boundaries of our so called ‘infinite’ universe?

How would that then affect our thinking about ourselves and about Space?

Well, perhaps you need to read up on the multiverse, the theory of which has been around for a while.

As to being not being infinite to make room for other universes, that does not necessarily follow. Multiple universes can be infinite and still have infinite gaps between them.

All highly theoretical, though. I don't think scientists have discounted multiple universes as they have not reached a point where they can say they have built an instrument that could see another universe, pointed it everywhere and found nothing. Our viewfinder is bound by our universe at the moment, so we can currently only measure stuff to do with this universe and idly speculate about the potential for other universes.

Thanks Siasl. I hadn't heard of multiverses before! But I have now...and I am still trying to get my head round the idea of  infinite multiverses - and maybe an infinite number of them, all expanding infinitely into infinite gaps between them...I used to be so happy being a flat-earther until you mentioned multiverses!
