What shape is the universe?

Answer 1

like a ring doughnut

Answer 2

Not to many years ago, the general or basically everybody thought the earth to be flat. Then due to pioneering discovery it turns out the earth was a sphere.

So theoretically if land mass permitted (which it does not), you could set of walking in a straight line and end up in the same spot as you set off!

Theories predict the that 4 D space-time is curved so essentially the same would happen if you set off in a spaceship in one direction, eventually probably billions of years latter you would end up in the same spot.

This idea also allows for the expansion of the universe theory (red shift observation) as space is not rigid and thus not fixed.

So it is in essences it is possibly some expanding 4 D spherical object. (3D spherical objects, sphere, do-nut)

Answer 3

Space is a dynamic, ever-changing, active thing—its shape changes as matter moves around in it.

I like to envision the shape of space as being that of foamy bubbles, amassed liked shaving cream spewing forth from its container. Within this analogy, each universe is a bubble, and space itself is an amorphous blob.

Starting in 1919, the geometrical theory of gravity (General Relativity) was tested—repeatedly and with increasing precision. It really does predicts what will happen more accurately than non-geometric theories—theories in which space is a rigid rectilinear framework and gravity is explained by force vectors.

So, once again, after 80 years of testing General Relativity, we pretty much accept that space is a dynamic, changing, active thing—its shape changes as matter moves around in it.

Fortunately it doesn't change very much except for very dense massive things, so we don't notice—it is still approximately the fore-square rigid spacetime that Newton imagined, so for practical purposes we still think of it like that.

Quantum theory comes in when you try to give this dynamic geometry, interacting with matter, a QUANTUM description—that means using stuff like wave-functions, and having uncertainty built in.

It doesn't mean that space has to be divided up into little bits (sometimes people think space must be made of quanta).

It means that things that you observe and measure about the geometry of space—like SURFACE AREA, and ANGLE, and VOLUME, and even the dimensionality itself—are no longer fixed definite things but are instead quantum observables (which can incorporate uncertainty).

For example, in a quantum model of a region of spacetime, the curvature is allowed to have some uncertainty—and depend on the quantum state of the system.

Answer 4

The largest structures we can detect with all our telescopes and instruments are shaped like the foam on the head of a good glass of beer. We can only see the foam to a distance of about 10 billion light-years, which is about a hundred bubble-widths in every direction from Earth. How far the foam extends is unknown.

According to BigBang boosters, gravity curves the space back on itself so that you have a 4D sphere, measuring 13.7 billion light-years across and 13.7 billions years old.

Some scientists (impoverished for lack of government funding due to the religious establishment of the Church of the BigBang) believe the foam extends to infinity in every direction.

Answer 5

unknown. we can't see all of it, because light travels at a finite speed and the universe was not always transparent to light - until about 300,000 years after the big bang, the universe was too hot and dense to let light pass through unimpeded. so we can "only" see about 14 billion light years in any direction. however the universe may be much larger than that, or possibly infinite in spatial extent (either model seems to work about equally well).

Answer 6

i would say its round based on my own theory, its round like planets only the inside has lots of space. the reason i think its round, if you look at stars, they too are formed from explosions (chain reaction) if the theory of big bang is correct, then an explosion will through everything on different direction at the same speed. this will create round shape like stars. but because stars are dense we can see this round shape but the universe has a lot of space between one object and another, it doesn't have any shape from where we are standing, 1- its too big so if we look at it from one side e.g. from earth, we could be looking on the horizon like it is on earth. standing on earth makes it look flat, so the universe would seem to be flat. 2-because of all the space, we cant make a shape out of it since galaxies seem to be placed in random location and don't form patterns.

Answer 7

It doesn't have a shape! Shape implies dimensions, boundaries and limitations etc which the universe can't have because it's infinite. However, our galaxy has a shape because we've decided where it begins and ends but the universe includes everything and so cannot have a beginning or end.

Answer 8

I portray the universe as a gas like substance with no particular shape or volume.

In my opinion the universe itself is infinite.
There are no walls covering its sides.
No boundaries. No start or ending.
No circle, no prism. Just a big pile of dark matter stretching on and on in all directions with nothing holding it back.

Answer 9

The universe is shaped like a blaminopheroid with a nondirectional phalanx of suppended teleoradiata.

Answer 10

I'm fairly sure that it's pretty much formless !?! Now if anything .,. If certain measurements are to be taken., to determain how far from whatever is considered the boundries of our own solar~system & then measurments that might be taken of a major source of light to another fixed sight!?! ..My answer is TOo long !! & may be end up tOo complex by the time I'm done !! I do have an idea !! just not a good way of explaining my meaning !?! ;-{} "R"r,r`r.r'r,r',.-

Answer 11

It's hard to pick any one theory on the shape of the universe, because each is possibly correct in it's own rights. Check out this site and see what I mean...
