What is there outside of the universe?

Question

People often discuss objects that are in the universe such as wormholes, planets, supernovas and much more....... But what consists outside of the universe?

Answer 1

here is 3 different views for you, the last one is the most up to date.
1/ if the universe is infinite there is no other side.
2/ if the universe is finite it's like a ball's surface.
A ball's surface has no edge, and if you're on it, you can't reach the surface's other side. Also, the surface of a ball is two dimensional and the universe is three-dimensional, which means you'd need a four-dimensional space to fully visualise a curved universe.
So the answer to what's on the other side of the universe is that the universe has no other side?
3/ scientist are now debating there are 11dimesions where the last dimension number 11 is what outside our universe and guess what? there's infinite parallel universes. look up string theory stephen hawkins for more info.

Answer 2

I think it depends on how you want to think of the Universe, but here is a break down:
The universee as we conceptualize it i.e all the stars, planets and space/ matter between them (the 28billion yr diameter of the univers) is like a grain of sand on a beach ball to the actual size of the known universe {14+billion yr} that is an 11 dimension configuration. So there could exist countless universes on this sphere.
This sphere exists in a space that is inconceivable to think of and there could very well exist countless of these spheres billion or more light yrs apart.
At a certain level you need to consider strings and membranes as the foundation of all matter, but that is kind of going downwards as to what makes up matter in it's most elemental form.
so outside the whole universe there are most likely other universes with a large empty space between them.

I would suggest looking up m-theory and string theory to flush out the information contained in this answer, this is not the forum for detailed explanations.

Answer 3

The universe is not a room or a shape or a bubble in space. The universe doesn't have an edge or boundaries. Learn about the least understood thing and that would be the 4th dimesion.
You learn all you can about the 4th dimension and you'l know more and see things clearer. You can't look at the universe with a conventional frame of mind.

Answer 4

Our universe? Nothing!..or less than that in fact. Space is defined in terms of the matter that extends it..and as our universe is still expanding...On the other hand, if as we believe at the big bang a period of 'inflation' took place..our universe is just one of many multiverses..and..wait for it..because there must be a large but finite configuration of fundamental particles..eventually there must exist an exact duplicate of our own universe, containing our selves exactly at this moment of time..but obviously inaccessible to us..also probably still born universes with no time..or any number of spacial dimensions..or where the laws of Physics are different..

Answer 5

If we define the Universe as all there is, then there is nothing outside it, or simply "non-existence" is outside the Universe.

Answer 6

Nothing, OR whatever you want to imagine.
We haven't mapped out the whole universe yet, so to start speculating what is elsewhere might be a bit premature???

Answer 7

Perhaps alternate universes

Answer 8

Nothing...Well apart from Absence of Light, and Absence Of Gravity

Answer 9

Why, lots of parallel universes, of course

Answer 10

Probably a McDonald's.
