Infinite Universe?

And this was actually my entire point. No way to know. Except, most "scientists" and mathematicians believe there is a limit to everything (energy) -- except philosophical debates. :) And if what you say is right then why so much confidence in what Stephen Hawking or Brian Greene or Michio Kaku say? I know as much as they do. :laugh:

Yes, but they know some extremely long technical words they can use to explain it! :-D

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:

That is not known, unless you use the zero-energy universe hypothesis, but then it doesn't limit the amount of mass either since the net amount of energy is independent of the amount of stuff.

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.
The universe could be infinite... Or it could just loop on itself like a circle.. or the surface of a doughnut....

The inability to form an infinite sidewalk from a finite amount of matter doesn't prove the universe to be finite.

The sum of all positive integer numbers from 1 to infinity is -1/12. Proven by science :)

When I was a kid, I wanted to see what the largest integer the PDP-11 could count to. Then I wondered what happened when you added 1 to that. It was amusing to discover that I then found the smallest negative number. Marc

I know. I was providing something for you to walk on. The point is if you could travel faster than the speed of light toward the end of the Universe then at some point all energy would be exhausted (not from travel but from the limit naturally created by an end of energy and you'd be at the end of the Universe. A physical thing must have an end -- a physical thing without an end is only theoretical. That is why we call it physical and not metaphysical. And I'm not saying that only in theory does the Universe end, I'm saying in fact it does because it is a physical object (we physical objects know this and study this and have our existence in a physical Universe). The instant you say the Universe is otherwise is the same instant it becomes non-physical and my final point then is that "all bets are off". So, the Universe (as studied by Scientists,Philosophers and Mathematicians) is a physical beast and as such has a limit and so has an end. Now you've heard the end of this discussion. :) Since, I've decided I am right. Yes, I'm kidding, but I do think what I've said makes sense. The Universe, if physical -- and it is, must have a limit. And if it isn't physical, then we aren't either. :laugh:

I'm saying something much more important here. I'm saying that the Universe is physical. If it isn't then we are talking about something that could even be an intelligence and then forget about understanding anything. I'm saying that since the Universe is physical and we are physical then it has a limit. An infinite anything instantly goes beyond physical and instantly becomes metaphysical and we cannot even hope to begin to study it. So, if we are going to believe in a mechanical Universe then it has a limit. If it has a limit then what is on the other sides? That is the real question. If it doesn't have a limit (if it were infinite) then it is not mechanical and physical.

Imagine you are an ant on the surface of the doughnut.... What do you find at the end of the doughnut? where is the end? what is the sound of one handed man clapping?

I see empty space above the doughnut. But perception does not change reality in this case.

Let me see if I've understood your argument:
- We are physical;
- The universe is physical;
- We have a finite size;
- Therefore, the universe must have a finite size.
Is that an accurate summary? Because if it is, I could replace "finite size" with "bumhole", and the argument starts to look rather silly. :laugh:

Thats, just like Drakes equation, full of assumptions. And like Drake, you are being rather optimistic. We already know that there is no sign of intelligent life in the observable universe. So, we have to consider the possibility that we are living on the first planet with some form of life. ..in which case we could refer to Windows 10 as "the prime evil" :rolleyes:

No. I'm saying, The Universe is physical and mechanical, therefore finite. I believe that most of your major scientists believe this too. They speak of "almost" infinite but never infinite. I don't believe anyone other than school children actually believe in any physical object that is infinite. Infinite is just a concept, but not reality in the mechanical universe. All physical (non-philosophical conceptual) things have limits. That's all my point is.

The rule is that measurable quantities cannot be infinite, but an infinite universe doesn't have a proper size let alone a measurable size. There is no contradiction here, an infinite universe can be physical. Whether talking about "the other side" even makes sense depends on the nature of the finiteness

That still leaves the question: if the universe has a finite boundary, what is beyond that boundary? Or are you saying that spacetime is a localized concept that has no meaning "outside" of our universe? (Not that there would be an "outside" in that case. Or a "before".)
