If the universe is expanding.......?

Question

Does this mean it has a membrane (and therefore of a finite size) and is inflating like a balloon, and will it therefore burst when the membrane can stretch no more?

(iii) The expansion of the universe

According to the Holy Quran:

“And it is We who have constructed the heaven with might, and verily, it is We who are steadily expanding it.” (51:47)

The word “heaven”, as stated in this verse, is used in various places with the meaning of space and universe. Here again, the word is used with this meaning.

At the beginning of the 20th century, the Russian physicist Alexander Friedmann and the Belgian cosmologist Georges Lemaitre theoretically calculated that the universe is in constant motion and that it is expanding.

From the moment of the Big Bang, the universe has been constantly expanding at a great speed. Scientists compare the expanding universe to the surface of a balloon that is inflated. Observing the sky in 1929 with a telescope also proved this fact. Edwin Hubble, the American astronomer, discovered that the stars and galaxies were constantly moving away from each other. These observations tell us that when everything in the universe moves away from each other, it is considered to be a constantly expanding universe. This fact was revealed in the Quran when no one knew about the expansion of the universe 1,400 years ago. This is because the Quran is the word of Allah, the Creator and the Ruler of the entire universe.

This is physics my friend. We live in a layer of space that we know as the universe where we along the first three dimensions of mass and one in a straight line known as time. The universe is created by something called a "brane" which is a membrane of existence. When two collide they create a layer of space or a universe. It is not a membrane it is a wall at where major quantum physics meet large levels the universe will not burst it just can't happen there are points where ew mass appears and disappears. But in over alll you can't look at the universe's wall as a membrane it is a non-existent thing the universe wil expand and so wil mass so this will prevent the universe from bursting and expansion shall continue...

Answer 3

The universe isn't expanding in the way that you are suggesting. The entire universe is just a large vacuum in which all matter is scattering in many directions.

So, going with your balloon analogy, the skin of the balloon represents the matter which has moved furthest from wherever the starting point was, and the interior of the balloon contains all matter and energy in existence.

There is no outer edge to the universe, because it is infinite. So, to sum up, the only things that's expanding is the distance between matter in our universe, not the universe itself.

Answer 4

The expansion of the universe does become hard to grasp when you expand your frame of referrence until it is larger than the entire known universe.
But, all the same, I feel pretty safe in thinking that the universe does not have some kind of membrane, or anything material, confining it.
That wouldn't seem to make sense.

Answer 5

The expansion of space is conceptually different from other kinds of expansions and explosions that are seen in nature. Our understanding of the "fabric of the universe" (spacetime) requires that what we see normally as "space", "time", and "distance" are not absolutes, but are determined by a metric that can change. In the metric expansion of space, rather than objects in a fixed "space" moving apart into "emptiness", it is the space that contains the objects which is itself changing. It is as if without objects themselves moving, space is somehow "growing" in between them.

Because it is the metric defining distance that is changing rather than objects moving in space, this expansion (and the resultant movement apart of objects) is not restricted by the speed of light upper bound that results from special relativity.

Theory and observations suggest that very early in the history of the universe, there was an "inflationary" phase where this metric changed very rapidly, and that the remaining time-dependence of this metric is what we observe as the so-called Hubble expansion, the moving apart of all gravitationally unbound objects in the universe. The expanding universe is therefore a fundamental feature of the universe we inhabit—a universe fundamentally different from the static universe Albert Einstein first considered when he developed his gravitational theory.

Answer 6

Yes,the univers is expanding.
The gravity limits the air around Earth and yet there i no membrane,like that i don't think there is a one around the universe.The matter in the universe stick togather b coz of the energies in it.

Answer 7

seems like membranes cannot burst when surrounded by the 11th dimension.

They can collide into each other causing (they claim) big bangs and possibly creating new membranes.

the brane isn't actually like a shell, its more like a separation from 11d and the others.

I really enjoyed it.

Answer 8

Not neccesarily...any tears that would occur would be smeared out at the quantum level.
Besides, you're imagining the universe sitting on something. The "fabric" of space doesn't neccesarily exist.
Personally, i think the universe stopped expanding...

Answer 9

there is no membrane in our universe
open universe you said
or big crunch or closed universe
just search for wikipedia if you don't know what i'm saying

Answer 10

Whenever I look at my tummy expanding, I remind myself that it's just the Universe.
