Re: Universe can't be infinite.

Physicists don't care about correspondence. They care about prediction. Utility! But they should care if something is possible or not. Infinity and eternity are not possible and they cause many problems. Many paradoxes occur because infinity is so illogical. For example Cantor's paradox, Galileo's ...

Re: Universe can't be infinite.

You are just a stickler for rules. ∞ + 1 = ∞ is axiomatic. The axiom doesn't (have to) correspond to reality. The fact that it does not correspond to reality suggests that infinity is not part of reality. It's impossible to construct actual infinity geometrically or otherwise mathematically. We hav...

Re: Universe can't be infinite.

And precisely because infinities are placeholders they could represent any real-world object that BEHAVES like an infinity behaves in the context of the equation. There seems to be nothing in the real world that behaves like infinity: ∞ + 1 = ∞ What real world object can you add to and not change? ...

Re: Before sliding down the bannister supported by Occam's Razor, wear iron pants.

There is the argument that the universe was created by something (God?). If it was created by something, it is designed and a well made design is just as complex as needed for the task and no more. So when considering the universe, if you believe in a designer, then Occam's Razor is still applicable.

Re: Universe can't be infinite.

You are trying to rely on intuition instead of mathematics. Unfortunately, that doesn't work with physics. If actual infinity existed as a mathematical quantity, it would be larger than any other quantity. But quantity + 1 > quantity, so no such quantity can exist and actual infinity therefore does...

Re: Universe can't be infinite.

That's not what the "expansion" means. There is more Universe (spacetime) today than there was yesterday. If the universe is infinite that's impossible; only a finite universe can expand. Also, the universe seems to have started with the Big Bang 14 Billion years ago and has been expanding since th...

Re: Universe can't be infinite.

On the subject of the OP, the universe is expanding so it cannot be infinite in space else there would be nowhere to expand too. Infinity is the problem: it's larger than any possible thing. Yet we require it to expand; implying it was not larger than any possible thing. So surely the universe is fi...

Re: Universe can't be infinite.

I agree with the OP. Time and space are both finite. I'm writing a paper on it which I've copied in below. Its really straight forward once you realise actual infinity can't exist... the rest follows... Abstract Eternalism is the belief that past, present and future are equally real. It contrasts to...
