If it’s finite, what lays beyond it?

Which one are you? Just as you’re thinking of them as you read this comment, they’re thinking of you.

[@Miss_Darko]

@@fred5107 Well the distribution of galaxies in the observable universe doesn't have the sort of uniformity we might expect if it had that recursive nature on a scale we can observe. This is complicated somewhat by the fact that, due to the speed of light, we do not see distant galaxies as they are in the present, but in their past states and positions, further into the past the further out they are from us. So far, though, we don't have reason to think that we can see our own local group repeated or mirrored somewhere out there. It's considered likely that the universe is finite in size though, and thus may have this sort of seemingly recursive topography on a large scale. However I think the usual consensus is that the total size of the universe is much larger than our "bubble" of the observable universe. This video does demonstrate how a universe that is actually much smaller could appear to be infinite, but the sort of scales it uses to demonstrate this are purely for the sake of demonstration and not representative of reality as far as we can tell.

Just a quick note: The 'repeating stars' concept is highly simplified. It assumes the universe is equivalent to a few wandering stars, but in reality, its vastness is unfathomable. It would be impossible to observe the same object twice due to the speed of light, yet the 'repetition' does eventually occur.

[@isavenewspapers8890]

The dimension of a space is the number of degrees of freedom needed to freely traverse it. Assuming you can walk both forward and backward, you need to face two different directions to be able to get anywhere within a sphere-space. Thus, the sphere is topologically two-dimensional.

[@isavenewspapers8890]

Wait, I have an easier explanation: The geographical coordinate system (GCS) allows us to label locations on the surface of Earth. This system uses two coordinates: latitude and longitude. For example, the latitude of the Great Pyramid of Giza is about 30 degrees north, and its longitude is about 31 degrees east. Using this system, we can label any point on the surface of Earth with just two coordinates. So, the surface of Earth-a sphere-is two-dimensional. It's embedded in a three-dimensional space, that being our universe, but from a topological point of view, its dimension is 2.

[@DigitalBard1]

Thank you cosmos, for suggesting such videos, at a time when I'm questioning everything. The idea of the universe being a 3D self repeating torus is fascinating.

[@lunarkomet]

[@excelsiorcomicsink]

So many questions. What if cone shapes to add to the list of torus and sphere and cylinder? Like how the Möbius strip flips, will there be many ways of contorting space to invert and mirror the moving object so that in POV 3D space, it will "appear" to crash into itself? This feels all so hypothetical as it occurs at perfect right angles of chaos. The maps of the shapes curve and wobble like how you were to cut a map off a globe amd attempt to lay it flat.

[@Alex-Defatte]

My favorite theory is the Möbius shaped universe. For some reason I can really imagine the universe on a weird wobble. Although, I can't find any examples of the shape in nature which leads me to believe it's less likely, it's still a very cool theory of space in the universe.
