Is our universe one in an infinite number of what describe as a universe?

Answer 1

The universe people think is infinite but in albert enstien general therom of relativity there might be enough mass to close the universe but not in a circular shape but in a oval shape as there isnt enough mass to make it circle but enough to make it oval and it is not infinite as it is 164,000,000,000 light years wide or 50 gigaparces

Answer 2

I don't believe many people hold that the universe is infinite in space, for two reasons: first, since the entire universe was compressed into a finite space at the moment of the big bang, and since it has just been expanding for a finite number of years since then, it can't be infinite now. Second, if the universe were infinite, there would be an infinite number of particles in every direction from a given object, such as your body. Every particle in the universe exerts a weak attraction (gravity) to every other particle. Therefore, since infinity times anything--no matter how small--is infinity, your body would be infinitely pulled in every direction at once, and gravity as we know it would be meaningless.

Almost all faiths maintain that the universe has had a definite beginning and will have a definite end. If it did have a definite beginning, this would seem to imply it had an external creator. Most atheists maintain that the universe has had no beginning and will have no end, and that any contrary claim violates the law of conservation of matter and energy.

This question cannot be answered by any known science.

Answer 3

This is where physics just implodes:

If the universe was infinite in size, that would mean that every single possible direction would go on for an infinite distance. But this can't be the case because if the universe were infinite, then it would be impossible to make any progress through space. Here's an example:

Say the universe was a line, with infinite length: (NOT TO SCALE)

__________________________________________________

0 Metres---------------------------------------------------Infinite Metres

And I wanted to walk 100 Metres along the line: (I am the "|" symbol)

_|_________________________________________________ (Before Walk)

0 Metres----------------100 Metres---------------------Infinite metres

_________________|_________________________________ (After Walk)

0 Metres----------------100 Metres---------------------Infinite metres

Now, I'm 100 Metres away from where I started, and 100 Metres closer to Infinity metres. But that is impossible, because you can't get closer to infinite, because it's infinitely large. So therefore I'm still an Infinite number of metres away from the other side of the line (the universe). And if I'm infinitely far away from one side, that must mean that I'm infinitely close the other side, therefore even though from my perspective I've moved 100 Metres, actually, I've not moved at all. So technically, I'm still standing at 0 Metres, despite having moved 100 Metres.

But, the universe cannot be finite either, because if it was finite, that would beg the questions: "What is outside of the universe?" or "What is the universe suspended in?" Because there has to be something else outside of the universe for it to exist inside of. And then we're just back to where we started: "Does the outside of the universe go on forever". As we've seen above, it can't be infinite, so is it finite? Well, no, because that must mean that there is something else outside of the outside of the universe. And then we're back to where we started again: "Does the outside of the outside of then universe go on forever?". As we've above, it can't be infinite, so is it finite? Well again, no, because then that must mean that there is something outside of the outside of the outside of the universe. And the cycle carries on, until you get an infinite number of outsides to the universe, like an infinite number of bubbles, one within the other, where the inner-most bubble is our universe. But this, again, is impossible, because you can't have an infinite number of bubbles because that must mean that the dimensions of the outer-most bubble would be infinite, which brings us back to the problem outlined with the diagrams; no progress in space would be made.

Weirdly, therefore, we can conclude the universe is neither finite, nor infinite, because both are physically impossible. But what if there was no outside to the universe, and the universe itself was finite? well that too would be impossible because our universe is expanding into something.

Our current models of physics can't explain how it works.

Answer 4

All we know for certain is our one universe. If our universe is one of many others in the same spatial dimension, we would call the overall structure the polyverse. If ours is one of many among other dimensions, we would call the whole thing the multiverse.

Answer 5

Probably. This, like many of the "big questions" in cosmology, really doesn't have a good answer, because we can (so far!) only observe the universe from one little speck of a planet deep in the gravity well of a medium-sized star.

Give us another hundred or a thousand or ten thousand years. Let us get away from the Sun, out to where space is "flat", and we may be able to give you better answers.

Right now, we're like a clam on the beach examining one grain of sand, and trying to imagine a limit to the Pacific Ocean.

Answer 6

Yes it is.

It would be impossible to detect infinity.
