I've always thought that the universe is essentially infinite. I think that when many people demand it must end somewhere; it's more a matter of having difficulty conceptualizing infinity when our whole lives are based around physical limits.


That being said, this is how I think of the universe: we have planets revolving around a sun to make a solar system. We have solar systems making up galaxies, galaxies making up clusters, and all those galactic clusters make up our universe. But the "universe" would have to be a cluster in itself. And if space is infinite, then there should be infinitely-creating universes elsewhere at a distance from ours roughly proportionate to our distances between galaxies.
For instance if our universe is made of 500 billion galaxies, and thereby 500 billion times the size of a galaxy in matter (bleh, I'm too stoned to calculate for dark matter right now), then the distance between "universes" would be 500 billion times farther than the average distance between galaxies. Or maybe it's just billions of times further than that even, who knows.

But anywhoo, the point I'm getting at here is there could be different universes with entirely different laws and aspects, and it wouldn't have to be in another dimension at all; just very far away! There's no saying that distant universes will be born by the exact same catalyst, and thereby taking the same form.
Of course now that I think of it, these far-away universes would probably be accessible via dimensional folds in the overal fabric of reality; seeing as quantum theory seems to be pointing toward the abolishment of distance/space between matter at the sub-atomic level.


Sorry to ramble, I'm having a great high for the second day after being 4 months without any weed. :stoned:
