Infinite Universe?

So good to see a Scientist who is committed to making sense. The Universe cannot be infinite since no physical thing could ever be infinite. Infinite is simply a philosophical concept until you get to metaphysical. So, science cannot deal with infinite. I'm glad we've had this discussion.

Possibly not. In which case, what is beyond the edges of this non-infinite universe? More universes? If so, what demarcates the edges of this one and the edges of the others? Can they not all be part of a larger universe? PS. My finite brain has just thrown a "Value out of range Exception"!

Perhaps more realistically or at least more philosophically pleasing, a finite universe could still be unbounded, for example if it is a 3-ball or 3-torus or something like that. That would mean that you could travel an infinite amount in any direction and never find "the edge" (since there is no edge) but you may find yourself returning to a place you've been before. The volume would be finite that way, but you don't have to worry about how space itself can even have an edge at all and what that might look like. But it isn't really known whether it's finite or not in the first place. It seems to be flat and isotropic, if it actually is flat and isotropic then it is infinite. But it might not be exactly flat, it might be curved less than could be measured so far. Or it might not be isotropic, or both.

Assuming the Universe is infinite then the number of stars in said Universe must also be infinite and therefore the number of planets orbiting said stars, that can support human-like life, is infinite and therefore the chance of there being at least one other human-like civilisation is infinitely close to 1. Therefore, do you think they would all have developed a Windows 10 O/S?

Yes. No. Maybe.

Apparently the number (-1/12) crops up in quantum physics so maybe not so philosophical after all.

I'd like to see that! Oh, wait, "crops up". That only exists in someones calculations they are doing. Yes, I'm trolling you. Just kidding. I understand what you mean, but do consider the Scientific Method[^], won't you? :-D

Maybe "space" is infinite, but the big-ball-of-wobbly-stuff we call "the Universe" isn't? :)

There are two kinds of people in the world: those who can extrapolate from incomplete data. There are only 10 types of people in the world, those who understand binary and those who don't.

Seems like that's an integer underflow problem -- you need a bigger processor.

My theory: The universe is like an expanding balloon with everything that currently exists sitting on the surface. Heavy objects like black holes, stars, and planets sink into the surface warping space-time to create gravity. If you could travel at a rate faster than expansion, you would eventually come back around to the starting point. The interior of the balloon is the past.

Thanks! Very Interesting!

I think it is infinite. Give me a minute... I think I have a map around here some place that proves it.

That was exactly the point I was driving at. And, I'm sure you are asking that question rhetorically. However, let us continue this line of thought. The fact that you cannot fathom what is on the other side does not preclude it and infinity is, of course, in a physical world, impossible. Here's your thought experiment to understand why infinity is impossible in a physical world. Thought Experiment Imagine you have a sidewalk that extends through your infinite Universe. You are walking on the sidewalk. Uh, it just continues forever? What would that mean? It's not possible. It's impossible since we know that even the energy (thus mass) is of a limited quantity in the Universe. Now, that gets you to a point where you absolutely must decide that the Universe (physical reality) has limitations. The hard part is that you will now have to confront that reality (few people do and fewer want to) and decide that you now know that physicality cannot be the only thing. Since the Universe cannot be infinite, there has to be an end somewhere. That means you must now contemplate what that means. :) Good discussion. And, I'm sure it's not done. :rolleyes:

Actually no. I disagree with you that infinity is impossible in a physical world. And I'm serious, if it ended somewhere, what does that mean?
