What is outside of the universe?

Answer 1

Nothing.

Nothing is outside the univers by defintion:

"The Universe is defined as the summation of all particles and energy that exist and the space-time in which all events occur. Based on observations of the portion of the Universe that is observable, physicists attempt to describe the whole of space-time, including all matter and energy and events which occur, as a single system corresponding to a mathematical model."

Answer 2

this is the most supported theory. to confuse you, its basically that our own universe is outside of our universe. ill explain:

The big bang theory says that the primevil atom (tiny particle of pure energy that existsed before anything else) 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

Your question is a logical fallacy.

Space-time is a property of the Universe. Since you cannot have "outside" without any definition of space, the words "outside the universe" are logically devoid of meaning. Likewise you cannot meaningfully ask what was "before" the Big Bang because time, a property of the Universe, did not exist before the Universe.

Answer 4

from the perspective of a materialist, it is an illogical and meaningless question, unless you have a funny definition of universe or fancy some of the "many-worlds" interpretations of quantum physics. some might say nothingness or nothing, but keep in mind that nothing is not a thing (it is NOthing) - and that's not a little something!

from a religious perspective (especially one such as christianity which claim that the material universe was created by God), God must necessarily be outside (or more technically, transcend) the universe. If God created the universe, then logically he cannot be the universe or part of it.

Answer 5

We may never know until we can create a craft that could travel outside the universe. Conceptually though, only the existence of the supernatural and Supreme Being or God could exist outside the universe.

Answer 6

BY definition, the Universe contains everything, so there must be nothing outside of the universe.

Answer 7

At this point we (mankind) are doing a pretty good job of trying to understand what is INSIDE the Universe. As yet we have not detected, observed, or seen signs of any boundaries to the Universe. So, it is not possible to state that the Universe has limits yet, or postulate what may be on the other side of those limits. Have you ever heard of or seen any reports of Stars, Comets, Planets, or Moons colliding with or bouncing of of the outer limits of Space? Probably not...

Answer 9

More universe.

HOWEVER!

It could go on forever like some people think, but it might stretch too far and snap back like a rubber band. Another BIG BANG. I don't know. It sure would be neat if all of these questions could be answered with real answers and not just theories.

Answer 10

Nothingness, Our universe has been expanding from the time of the big bang and the outermost edges are expanding in a vacuum where nothing exists, not a speck of dust or single atom.
