I meant to reply to this, lost track of it. Search to the rescue!
Thanks for posting it. Yes, I can see the infinite flow (very cool program actually -- reminds me of some of the screen savers when they were still popular/necessary).
I think the universe is infinite -- meaning there is no end. No borders, no boundaries. It just keeps on going and going. (Mind blown!) And therefore no center either. If there is no center, there was no big bang and the inconsistencies between big bang theory and what we've observed are no longer problems! In physics, the simplest answer is usually the right one.
Well, for all intents and purposes, it's infinite as far as humans are concerned because we can't even see the the ends of what's visible or detectable let alone travel out there to see otherwise. I hope we might be able to one day, but for myself, it actually gives me a sense of well-being (perhaps calm is a better word) knowing that more things are possible than our minds are able to comprehend.
