The finite universe theory? Is it plausible?

Question

If the universe is a bubble that keeps expanding, then there must be a void of nothingness outside. But if there are many bubbles, then what is between them? It must be more space. Is the gigaverse finite? If it is then what is outside it?

Also there must be a centre and a beginning if our universe is finite.

Answer 1

I believe that space is infinite. You answer the question when you ask what is outside it. The actual stars, planets, etc in what we call our universe must be a finite amount.

Answer 2

There's really three points here--as to the first: the "universe" is finate--in that it is an expanding but bounded region containing the large (but finite) totality of mass and energy that is the "stuff" of the universe. As to what is "outside the universe--there are various theories, but that's a question science isn't able to ansewer (yet).

Is there a beginning? Yes--that's what the "Big Bang" theory says.

The notion of a "center" as you state it, however, is not (exactly correct. Based on current knowledge, we think of the universe as being on the "surface" of a 4-dimensional bbubble. By analogy, if you thing of a balloon, it exists in 3 dimensions, but the surface is two-dimensional. The universe is a 3-D "surface" on a 4-D "bubble" that is expanding. So in 3-dimensional terms, there is no "center"--though the concept might be valid if framed in a multi-dimensional context.

Answer 3

The universe is definitely finite.
At one time it did not exist and one day it will go out of existence.
it"s an incident that happened once and will never happen again.
At some point after time zero a space-time pulse came into existence.
It accelerated outward for about one-thirty billionth of a second,it expanded into nothing.
When it reached a radial velocity of the speed of light,the acceleration stopped,leaving a primary universe about as big as a marble.
This quantum entity of incredible density,had no matter,no gravity,no strong or weak forces and no electromagnetism.
It contained quantizing errors that would turn it into what we Experience to-day.
The eventual demise of a universe is hard to imagine.
The expansion will diminish it"s density to a point beyond which it cannot exist.
By the nature of a quantum universe,it must be finite!

Answer 4

You are right. Outside the universe is a 'shapless, formless, void' that cannot be understood because words do not exist in it, math does not work in it, and thought has no grasp of it. It's the exact same thing there was before the Big Bang. As the universe expands, there is more space between objects. Only because space is DEFINED by matter. Without matter, there is no space. The center of the universe is in the forth dimension - of time and space. For us 3-dimensioners, the entire universe IS the center of the universe. It's beginning was at time>zero. It's end will be at time

Answer 5

If you use the analogy of a sphere as representing our universe then you will see that our universe can be finite and still not have a centre.

Imagine a 2d being living on the surface of a sphere. If they walk around the surface they will come back to the point at which they started. They can therefore conclude that 'their' universe is finite. However they still cannot indentify a point on that surface which is unique and can be indenitified as the centre.

Answer 6

The finiteness of the universe is not only plausible, it seems easier to visualise than an infinite one.

As for anything outside the universe, it can't be space by definition since this comprises most of our universe.

An outside would have to outside our experience. I prefer to believe that there is no outside but perhaps that just indicates a limitation of my imagination.

Answer 7

The boundaries of the universe are defined by the matter/energy which comprises it. Keep in mind, however, that it's not just planets and stars and galaxies expanding into vacant space. It is the fabric of space-time itself that is expanding. "Outside" of this there is nothing, not even void, just a philosophical abstract concept.

Answer 8

the present theory is that it certainly does 'bend' like Einstein pronounced (think of of somebody from a 2 dimensional international, status on the exterior of a sphere, you're able to flow in any path, and finally come again to the place you all started!). "or could our universe be like an air pocket in an stronger area?" we don't be attentive to! it may be no longer uncomplicated to make a distinctive end, as we can basically somewhat take measurements from 'interior' the universe (on the 2nd), and the only 'physics' all of us be attentive to is that of the universe, so it may no longer additionally be obtainable to come again to a determination/describe! "what variety of length proportions could you be observing?" length (during which I advise quantity) is a theory-approximately area, so if there is an 'exterior' of the universe, there desire no longer additionally be this variety of element as 'length' or quantity. super stuff to philosophise approximately!!

Answer 9

If you go with BB big bang, singularity, boom, expansion etc exploding into what.....
S Hawking is keen on baby universes/bubbles and
Penrose has his own ideas.
As for me I like void as well.
It is truly infinite, universal and eternal.
Everything else like universes, matter, life etc comes and goes..
However I do not see the void as an empty place

Answer 10

It is as plausible as an infinite universe. Both ideas are beyond human comprehension.
