What does the outside of the Universe look like?

Question

I know that the Universe is expanding, not infinite. So what does the outside of the Universe look like? Is it just blackness, with 0 matter 0 dark matter and 0 dark energy? Is there gravity? Is it a vacuum?

I bet nobody can answer this xD

Answer 1

There IS no "outside" the universe. It doesn't exist.

Space-time is a property of the universe, and the word "outside" implies a spatial relationship. Since there is no space, there is no outside and nothing to see.

Answer 2

Well, the last time I was there, they were just in the middle of redecorating it. The old, brown paint was flaking and chipping away, and the vines covering it were in a sorry state, too. Next time I go, I'll take a hyperdimensional photograph for you, okay?

Hey, they're your points - waste them any way you like. Ask all the unanswerable questions you want.

Answer 3

on the outside of the universe, you wouldn't see anything because light can't leave the restraints of our 3 dimensional universe.  If you were to leave our universe, you would have to travel along the fourth spacial dimension.  Since light can't travel along that axis, you would see nothing.

Campbell is exactly right.  And as for the person below me, most physicists have come to agree on the concept of a multi-verse.  An large region outside of our universe where there are constantly universe's being sprung up, destroyed and even split off of other universes(sort of like soap bubbles in a bathtub.

Answer 4

Nobody knows where the universe ends so you are gonna have to wait because we don't have the technology to go that far yet.

Answer 5

There is no outside. Or the "outside" would be non-space. Or another dimension, or the 4th dimension.

It is analogous (not like, but analogous) to what the world looks like to us. I mean the 2 dimensional world, like plotted on maps. Where the world is all the countries and oceans and mountains there are, as far as you can travel by walking or car or boat or even airplane. There are only so many square miles of land and sea, not an infinite number. So where is the edge? If it isn't infinite there must be an edge, right? Like a cliff you would fall off. And what holds it up? Well you know. The surface is curved back on itself in a ball and gravity pulls toward the center of the ball, which is 4,000 miles underground and we can't get there. And the edge is the ground we stand on. Every time you jump or fly in a plane you go off the edge, but gravity eventually pulls you back.

Now think of the 3D universe in an analogous way. You could go right or left, forward or backward, up or down, but no matter how far you went in any of those directions you would not come to an edge. But you could (in theory) measure the total number of cubic miles in the whole universe and it is not infinite. So where is the edge? Right here. Everywhere. Just like the edge of Earth is everywhere.

The difference is, we are not 4D people in a 3D universe in the same way we are 3D people on the 2D surface of the world. We cannot see or feel the 4th dimension or even imagine what it might be like. And we cannot jump into the 4th dimension. Except in science fiction stories. But all those things can be mathematically described and calculated.

I suggest reading the book "Flatland" to get a better idea of what I am talking about. If you are really interested in trying to wrap your mind around what it would be like. Read it online at the source or check it out at the library or buy a copy.

This is the 3rd Heaven where God dwells.

2 Corinthians 12:2-5

1st Heaven- the atmosphere

2nd Heaven- the cosmos

Answer 7

ok, I"m standing outside the Universe, looking  into it... what do I see?... gadzillions of stars and galaxies and groups of galaxies all heading at me at speed!!!!... DUCK!!!....
