What shape is the Universe?

Question

Is it 2D or 3D and what kind of shape is it? I think it's the shape of a ball with the centre being the 'start' of the Big Bang and everthing expanding from that point outwards in all directions. Some say it's the shape of a slice of bread, ie flat. What do you think?

Answer 1

I humbly acknowledge that I might not be able to answer you question as accurately as you may have hoped, I do however like to mention some important points that I think are related to your question. They might as well interest you while you are thinking along these dimensions.

First of all, I like you to realise that by asking this question you have create a virtual standpoint for yourself that is outside the world you and me live in - this is somehow natural to human mind and it signifies its powerfulness. Now, if you find yourself standing at a distance from the world you are a part of now then you are an observer or a witness of your now previous world instead of being a habitant of it. I now ask that, is it possible? Can there be a place for human mind, or in human mind, where one can reach and observe it all?

If all that is there is the universe, or universes both physical and none-physical, and there is no place blank that one my call a blank, a void, a nothing, or a non-existence. In order to be there you need to create something in place of that nothingness.

Your question has just created a little more of this universe. It has added something into it. You can observe the universe as it was before you asked your question but now you will have to ask another question in order to observe the universe and the place created by your question - you will have to create yet another place attached to an existing universe. You see, if we keep asking questions ourselves, our mind will keep expanding but we will not reach the end of our quest - we will always have yet another question in front to answer.

I think we need to bring ourselves in a certain state of acceptance instead with faith and certainty of our existence. And then we can nurture an objective sense of curiosity in our consciousness, and explore the limits of our knowledge. We can be ready to anticipate and observe from the countless possibilities of an endless world – limiting our mind in an effort to understand it all will not eliminate possibilities. If we are welcoming and ready then we can choose objectively from a human standpoint what is best for us to see and observe as the best fitting model of the universe, and our journey through its awe inspiring beauty and grandeur.

Answer 2

An important open question of cosmology is the shape of the universe. Mathematically, which 3-manifold represents best the spatial part of the universe?

Firstly, whether the universe is spatially flat, i.e. whether the rules of Euclidean geometry are valid on the largest scales, is unknown. Currently, most cosmologists believe that the observable universe is very nearly spatially flat, with local wrinkles where massive objects distort spacetime, just as a lake is (nearly) flat. This opinion was strengthened by the latest data from WMAP, looking at "acoustic oscillations" in the cosmic microwave background radiation temperature variations.

Secondly, whether the universe is multiply connected, is unknown. The universe has no spatial boundary according to the standard Big Bang model, but nevertheless may be spatially finite (compact). This can be understood using a two-dimensional analogy: the surface of a sphere has no edge, but nonetheless has a finite area. It is a two-dimensional surface with constant curvature in a third dimension. The 3-sphere is a three-dimensional equivalent in which all three dimensions are constantly curved in a fourth.

If the universe is indeed spatially finite, as described, then traveling in a "straight" line, in any given direction, would theoretically cause one to eventually arrive back at the starting point.

Strictly speaking, we should call the stars and galaxies "views" of stars and galaxies, since it is possible that the universe is multiply-connected and sufficiently small (and of an appropriate, perhaps complex, shape) that we can see once or several times around it in various, and perhaps all, directions. (Think of a house of mirrors.) If so, the actual number of physically distinct stars and galaxies would be smaller than currently accounted. Although this possibility has not been ruled out, the results of the latest cosmic microwave background research make this appear very unlikely.

Answer 3

Our universe has threee SPATIAL dimensions so you would say it is "3D". Its shape is not easy to describe, because our notion of shapes is of confined things (things with a boundary, edge or skin) that are themselves 2D or 3D. To make any meaningful answer about the shape of the 3D universe, it would have to involve at least four spatial dimensions (that is, NOT counting time). However, the nature of the "shape" of our 3D universe depends on the Fifth Postulate of Geometry: do any lines through a given point go parallel with a given line? The answer seems to be one of NO, YES-- one line; and YES - infinite lines. THis comes out in the long run to saying the total number of degrees when you add the three angles of a triangle: 180 degrees? Less? More? THis can be tested through Einstein and the stars. The answer seems to suggest that the answer is "slightles LESS than 180 degrees", which would suggest that our universe, if it were a 2D object in 3D space, would be sort of saddle shape (or like a Pringle!). THis doesn't sound like it could apply to 3D, but it does as well! So the answer is: the universe is sort of saddle-shaped.. MAYBE.

Answer 4

Some people say the big bang began in a few places, but this implies that place/spatial dimensions existed before the big bang, and they did not. So my guess is that the universe began spherical from a single point but because of inconsistensies would not have stayed spherical for long, and we have the extreme result of that now - clusters of galaxies with very little in between. As the universe still expanded in every or lots of directions with these huge gravitational accumulations existing, then the shape must surely be a product of what effects the clusters have. It can't be spherical if the matter that makes it is so non-uniform. In short, a blob!

Answer 5

>>a million. curiously the Universe is increasing. no matter if it really is increasing and in no way infinite, would not that advise that theoretically you should attain the "part" and previous of the Universe? What then? Limbo? Or is it purely void? yet void is area although. remember and means can exist in area. If previous the Universe replaced into purely void the Universe should be defined as how a procedures out remember is going.<< you're questioning is logical, yet regrettably uncomplicated good judgment would not artwork after we communicate about some valuable homes of the universe. The universe is declared to be 'isotropic' and 'homogenous.' truly what which ability is that no remember the position you're in the universe, that position will seem on the midsection of the universe. Earth looks on the midsection because after we glance outward in all guidelines we see the universe increasing remote from us. notwithstanding, once you're on yet another planet a million-million mild years from Earth you would see the very similar element. the final analysis is that there is no part to the universe. >>what's increasing in the Universe. Is it purely remember flinging outward?<< First you should comprehend that each thing -- mass, mild, all kinds of means, you and that i, etc.,. -- are embedded in the "fabrics" of area. the answer on your question is that that's area that's genuinely doing the develop and remember is purely going alongside for the experience. >>Does the Universe boost in all guidelines?<< From any poiint in the universe, like Earth, the universe is increasing in all guidelines. yet undergo in ideas -- once you're on another planet mild years from Earth an same element should be real (the universe is isotropic) >> is there and how can there be a "structure" to the universe? << yet another hard question! There are 3 diverse shapes the universe would have -- a million. Open (hyperbolic with unfavorable curvature). in this sort the universe retains to boost indefinitely; 2. Closed (round). At your time in the destiny the universe ought to stop increasing and give way back on itself; 3. Balanced universe. At your time in the destiny the stress of gravity precisely equals the stress of develop and the universe purely stops increasing without next give way. Of the three, all modern-day observations strongly advise that #a million is the issue of our universe.

Answer 6

Blimey!! The invisible universe in my opinion has no shape because it has no physical properties, but the visible part of the universe like the planets, galaxies etc probably form a sphere or near as damn it because if you believe in the big bang theory it must have started from one point in space and time! The earth and other bodies are round because mass creates gravity therefore it pulls into itself creating a ball, and the solar system is flat as are the galaxies because they spin on an axsis, and anything that spins wants to spread from the centre like a pancake. OH! I DON'T KNOW......................How big is the universe anyway and where does it end! You can send yourself crazy thinking of that one!!!!

Just Look @ Me!!!!

Answer 7

One misconception in this question is that there is a point in the universe from where the Big Bang expands. At the instant of the Big Bang it was the whole universe. The Big Bang has always been the whole Universe. The Universe/Big Bang has just got bigger - 14 billion years bigger.

Answer 8

if you mean what is the distribution of matter, how is it arranged then it has a very similar shape to the arrangement of neurons in your brain, but rather than neurons there are long chains of galaxies. Its like a 3d spiders web which rather than being flat.... actually goes out in all directions. Imagine a large balloon full of spiders who all try to make webs but end up joining their webs to each other! so you get a real 'super web'. Now take away the balloon and imagine the webs all stay where they are and don't collapse, that's the shape of the universe, which is also the shape of the arrangement of neurons in your brain.

Answer 9

I think this answer will never be answered but in my theory, everything is made of atoms and an atom is round so I assume that goes for the biggest known object which is the ever expanding universe.

But the maddest thing to ask yourself is if the universe is expanding either way then what is outside of the universe?

Answer 10

It is definitely not 2D and It is more than 3D. It is so big that you cannot imagine with the current findings, May be in the future. But it is assumed to be Round or Oval and to add, it is also thought of that there could be other universe like this too... Imagination would not stop there.

Answer 11

Hi,

I think more or less like you. It also expands and there are other balls of universes. When these hit with each other a new big bang occurs and a new universe forms.

There is truth in what I said according to some scientists theories.
