Is the universe finite or infinite?

[lh-crypto.biz]

I think it's finite, but this is where it starts and ends.....

Infinite in many ways (dimensions) finite in others (time), but maybe it is impossible to measure, from within this confine, or "plane of existence".

If you bring God you have to bring life after death, and if you bring that you have to bring life before being born. Where do we come from, and where do we go. I'd rather pick the agnosticism route, as its less arrogant than atheism, which by definition demands faith into not believing something you might never be able to grasp in the first place...

And, if time started at big bang, what was there before it?

Physics... where the fun starts.

It's circle within circle, infinite just like your "empty" soul and the incarnations that you will go through life after life or death after death.

damn that deep bro.

How can we truly understand infinity, when we are only finite beings, that have a beginning (birth) & an end (death)?

But if it's finite, then what is surrounding it? And what is it expanding into?

I have always thought of the universe as being finite but unbounded (i.e. no edge). I would say that the thing it is expanding into is time.
The analogy is blowing up a balloon. you start with an un-inflated balloon. It has a finite small surface, and you can go anywhere on the surface and eventually get back to your starting point. Mark some dots on your path. They will have a certain spacing between them.
Then you start to blow up the balloon. It expands, and the surface of the balloon expands. The spacing between the dots increases. But still you can travel all the way around the finite surface of the balloon to reach your starting point - it's just that the balloon got bigger over time.
The surface of a balloon obviously being 2 dimensional (forwards and sideways) - just raise the analogy by an extra dimension to see the universe as a 3d surface of a 4d object (with time as the fourth dimension).

Just a theory, but it's one I like.
