What does the edge of the universe look like?

Question

I was reading the idea that the universe is finite without boudnaries and expanding onto itself


but if I could HYPOTHETICALLY fly to the edge of the universe

( I'm not sure the exact shape -- I'll assume it's a sphere)

so X light years radius I drive from the center ...to the point where it's expanding at that INSTANT ...what would I see? Could I touch it ...would it not allow me to get and further out
..is it like a brick wall

If It were like a sphere....then there has to be something outside that sphere....outside of space and time ...any ideas?

Answer 1

Most likely you would see nothing at all. Other than your own spacecraft. You could continue infinitely farther away into nothingness because the big bang hasn't arrived there yet
***********************
Another theory is that you would hit a wall and travel through it. When you penetrated in you would pop out the singularity at the center of our universe from which the big bank emanated and start all over again.

This is the mobius theory. Would the universe you pooped out be the same universe. Yes but time would have been reset. If this is true, we are all on our way to becoming our own big bang.

Be careful about the statement " Most Scientists Think"

While I believe all scientists think, they certainly do not think the same thing. The only consensus for certain is that they agree that we do not know.

well most scientists think the universe is infinite... in a way, it has bounds but no end. this will explain it, i typed it a while ago and dont wanna retype it.

Well the big bang theory says that the primevil atom exploded and when it did that released so much raw energy that it actually created space and time. so the expansion of space would have to have a speed, because nothing is instantaneous thats quite impossible. so there has to be a point where space stops, and when space stops you cant go any further, there is nothing. thats different from there being no matter. having no space is like having 1 atom, but no where to put it.

so if there is a definate boundry to space then there has to be something beyond it, and there would have to be a spot you cant go any further, this is also impossible. because nothing can be beyond the limit of space because theres, obviously, no space. and there cant just be a wall that you hit and cant go any further, no credible scientist believes that. so what is the universe expanding into?

the only answer that allows all of that to be true is that the universe is 4 dimensional. so if you went in a shuttle forever in one direction you would never reach the end, you would just end up right back where you started (this is not a sphere, its a hypersphere which is a 4 dimensional sphere. if it were a sphere there would have to be something outside of it).

a good example of a 4 dimensional object like this (its not really 4 dimensional, but its has a property of 4 dimensional objects, it doesnt have an end) is a mobius strip.
take a piece of paper and cut and inch long strip, then twist it 180 degrees (so it looks like DNA does) and then tape the 2 ends together. you can now take a pencil or pen and start at the taped end end draw a line one direction. you will draw the line on both sides and end up back where you started.

if that was to confusing im sure you can go on google and type in mobius strip and it will tell you how to make it.

Answer 3

Finite or otherwise, the universe is unbounded. That means even a boundary beyond which there is empty space doesn't exist. You read this yourself and it is true. You cannot even hypothetically visit something that doesn't exist, even if you put "hypothetically" in full caps.

The Instigator got two thumbs downs from the vast hoards stuck in Euclidean head-space who think that the big bang was an isolated explosion in a pre-existing infinite vacuum. I'm feeling a bit left out :-(

Answer 4

At each point of the universe the viewer would appear to be at the center of a sphere with a radius of approximately 13.7 billion light years. So the universe basically wraps around. Of course, as you look further into space, you're looking back in time, so what you see at the "edge" from your vantage point, is the very infancy of the universe (no matter which direction you look). Weird and complicated, isn't it?

Answer 5

There is no edge. And as I keep telling people, the Universe is the totality of existence. There is no 'outside' or something else. And the Universe is more than mass/energy in space.

Answer 6

You said it yourself - finite without boundaries. That means there is NO edge. This isn't a certainty, but sounds likely to me. I wouldn't be surprised if it turned out to be infinite. Either way, nobody expects boundaries. (i.e. an 'edge')

The analogy they like to use is to the 2D surface of a 3D sphere... imagine you are a 'flatlander' and you only exist in 2 dimensions, like a drawing on paper, but instead you are a drawing on the surface of a sphere, like a planet or moon. Now pick any direction and move... you never encounter a boundary.

Mathematicians have no problem extending this analogy to 3D creatures in a 4D 'hypersphere' that is finite, but has no boundaries.

ooh, neat, a thumbs down... looks like someone has no clue.


keep in mind that the big bang happened RIGHT HERE... everything and everywhere was in one place. That means this stuff and this place were also there.

Answer 7

The outer edges are kind of tight, youd have to force yourself to the negative apex. The shape is not spherical. It's more like an atommy/crystally shape that is not infinate, but grows as it melds into other existing phenominomms. As far as the center, believe it or not the center of the universe lies in our minds. Whoevers thoughts are the strongest at a time, controlls the universe. When many get togeather, the thought just expands. So doews the universe. One verse. A doppler* affect of effects. We revolve arround ourselves.

Answer 8

Its a wall with an illustration on it announcing no peeking. extremely even with the undeniable fact that, it relies upon which of the wager theories of the universe you think approximately. recommendations are: there is plenty understand that area bends back on itself, this one has no ingredient, in case you went a techniques sufficient in a million course you finally end up back the place you start up up from. there is not sufficient remember for area to bend back on itself, in this manner the greater you pass the fewer there is there, remember thins out and there is not something to work out, in the back of you're each and every of the celebs, infront blackness, not even any mild comming back your way. The universe is an area time bubble in a limiteless sea of ether, this one has a wall, yet th nature of the wall is disappointing, its greater like a thickening jelly that grow to be harder to get by way of. You wont see or journey this thickening on account that its an area/ time consequence, to you all looks generic, yet to somebody watching you, you decelerate.

Answer 9

I think you would enter into another realm and a possible new and different Universe outside of this Universe. Maybe Heaven exist there? Or maybe that is where De Ja Vu exist?
Sounds like a great Movie!
Instead of Universe, meaning One, it is probably BiVerse or DuoVerse????
The mind is a wonderful place to explore.

Answer 10

You'd would eventually pop out of the dark bubble, like a fish in pond and be very scared because its not anything like what you're used too.
