What is out of the universe?

Answer 1

universe is supposed to be infinite and contains all.To talk of out of universe, would be to limit the universe,which will not be a universe then.
however talk of parallel universe will be possible if one is outside this universe ( from within the universe, universe is infinte)
it should obviously involve more dimensions than 4.It is difficult rather impossible for 4 dimensional beings , to imagine from within .
one can try but will come up with illogical explanations like :
if you look closer, you will find a twisted wire displaying other dimensions, which is otherwise normally single dimensional from a distance:
or something like that which will actually destory limits as dx tends to zero concepts in mathematics, which are fairly understood, proved to some extent, and the results of which are closer to truth.
in these questions, anything is possible.
you should come out with your own theory and explanations.No body has monopoly in these matters.

Answer 2

By definition, there is no such place as "outside the universe". Also, more and more the data indicates that the universe is infinite.

The analysis of a 3 year gathering of data about the Cosmological Microwave Background radiation (by WMAP) appears to exclude most possibilities of our universe being finite. As Sherlock Holmes would say, once you have excluded all other other possibilities, what remains, however improbable, must be true.

It also appears that our universe, in addition to being infinite, may also be curved upon itself. In the same way as if you consider Earth's surface to be a 2-D space, it is curved so that if you start off in one direction, you will eventually return to your starting point without having to turn around.

Except that with an infinite 3-D space, the "round trip" will take an infinite time.

The "nice thing" (mathematically, that is) about an infinite universe is that it does not need anything to expand into. It expands into itself. There is no end (being infinite in size) where the "edge" of the universe gets pushed outward.

However, there are other theories, some in which the "Universe" is much larger than the portion that we call the universe. In many of these theories (or versions of the multiverse theory) a tiny portion of the much bigger "Universe" started growing about 13 billion years ago to form the portion of the universe we can see.

I personally find these other theories less useful than the one-infinite-universe, but that does not mean that I am right. It simply means that the other theories (where there would be places outside our universe) are a lot more difficult to understand and to use.

Answer 3

Lots of space in the universe.

What's outside that? You have no concept of the incredibly immense depth of the universe. Even studying it nearly every day of my life, the concept is constantly in flux, like a moving target. Until we master space-time continuum travel, the likes of which we can't even imagine today, and can actually travel to the "ends of the universe", we will be stuck asking that question.

Accept the situation that there will be some things you will not know in your lifetime. Learn all you can.

Answer 4

We have no way of knowing. We can't point in a direction and say, "That way is out." We have no way of exiting our universe.

Yet.

Answer 5

By defintion the 'universe' is everything there ever was, is now, or ever will be.

Answer 6

there isnt anything outside the universe. and yet the universe is finite. fascinating isnt it...

Answer 7

space

Everything that is not in.

Answer 10

more than i think we will ever know about.
