What is outside the universe?
There are several theories about the universe. Some believe is it an ever expanding singular place where everything exists; another theory is that several universes (Bubble Theory http://en.wikipedia.org/wiki/Multiverse) exist and they are bumping into each other possibly allowing for cross universe travel. Of course you can always catch a few episodes of The Universe (http://www.history.com/shows/the-universe) or The Known Universe (http://channel.nationalgeographic.com/series/known-universe/all/Overview) and maybe read a book or two on the several theories.
What lies outside our universe?
The concept behind the word "universe" keeps evolving with new theories, conjectures, and knowledge. Before about 1922, scientists thought that our Milky Way Galaxy was the whole universe. Now we know that our galaxy is just one of billions of galaxies. More recently scientists have been discussing various kinds of hypothetical multiverses. The idea of a multiverse is that what we call the universe of billions of galaxies could be one of many universes in a multiverse. With this kind of hypothesis, what is 'outside' of our universe is the multiverse. As you can see by the collection of answers to your question, there is a conflict about the definition of the term "universe". Some people use the definition: universe = everything in existence. Other people, who consider the possibility that our universe is one of many universes in a (hypothetical) multiverse, are using a different definition of the term "universe". If there actually is no such thing as a multiverse (a possibility for sure), then there is probably no such valid concept as "outside our universe". To be clear about the general multiverse idea, there really has to be more than the usual 3 spatial dimensions in a multiverse. With all ideas of the multiverse, you can't just 'look over that way' to see a neighboring universe. You'd have to 'look' in a spatial direction that we cannot presently detect. It would require looking along a fourth spatial dimension, which we can't do and may never be able to do.
What is outside the Universe?
By definition, the universe includes everything, so the short answer to your question is: nothing is outside the universe. Here's the longer version: think of space as the rubber of a balloon. At the Big Bang, all this rubber was scrunched into a tremendously-small ball, with no air. Then, at the Big Bang, air is blown into the balloon. It expands by stretching, as the balloon inflates with the air. The first key idea is that the rubber has been there the whole time - it is just stretching. The second key idea is that there are two opposing forces: the air being blown into the balloon (the energy of the Big Bang), and the tension of the rubber (gravity). These two fight each other. If the air wins, the balloon goes on expanding forever; if the rubber is too tight, i.e. there is too much gravity, it will collapse instead. Deciding the fate of the universe comes down to determining the balance of these forces. A final point: notice that the amount of rubber in a balloon is finite. You can calculate it easily, and it's not infinity. However, the balloon (ignoring the little neck where you blow!) has no edges, either. That is, space is finite, but it has no edge. This last point is key to your question: space can be finite, but still not have any edge. Without an edge, how could there be anything else besides the universe? There is no edge you could ever walk up to and say, "Here's where the universe ends, and where the stuff outside it begins." If you went far enough in one direction in the universe, then (just like if you walked around the surface of a balloon), you would come back to your original location! This analogy is helpful, but imperfect. It is easy to picture the universe as a balloon, but then you think, "Balloons expand into something, like a room!" But the universe isn't the balloon itself, it's the *rubber surface* of the balloon. If you keep that in mind, you can take the analogy pretty far. Hope this helps!
What is outside the universe?
@ Why you feel the need to try and belittle me because I have asked a valid question is beyond me! I do have an education thank you very much, to a very high level in a scientific subject may I add, I know and understand many of the theories that exist about the universe but they are just that, THEORIES, give me indisputable evidence and I will accept it whole heartedly, until then they still do not ring true to me, I feel this is a difference in opinion or "belief" rather than me being less intelligent than you!! Thank you everybody else for your explanations, they have provided me with food for thought :)
Is it pure white outside our universe?
The truth is...we don't know what's outside the universe...we have many theories...but nothing concrete as far as evidence. The "end" of the universe is not within our grasp .....what lies beyond...is even more so.
What is present outside universe?
There is “ NO “ outside of the Universe.DEFINITIONS --THE UNIVERSEThere is only “ ONE “ Universe, and has always been here, and is infinite. You can not expand infinite, change, or reduce it.OUR FORMATION“ OUR “ formation is all of the Galaxies around us - to make it simple. There could be any number formations like ours, or only one - “ OURS “ which could be part of another or several other formations like ours. During the expansion of OUR FORMATION - ( The electromagnetic spectrum has accelerated at the speed of light sense it’s developed, and continues to the present. Matter has been expanding at a much slower rates. ) - The "GRAVITATIONAL PULL" from the FREE FORM GRAVITY, ENERGY, and MATTER that extends far beyond the present location of our galaxies is pulling the galaxies outward, and to be clear, the electromagnetic spectrum and matter are moving in all directions.There was never a Big Bang, the beginning our formation began with a little “ UMPH “.http://www.creationoftheuniverse...

Is heaven outside the universe.?
After the 1000 year reign of Christ Jesus on this earth... we learn that this world as we know it shall pass away.. along with the heavens. The new heavens and earth shall come down. The new Jerusalem will appear and we shall be in heaven with God the Father.
Is there empty space outside the universe?
I’ll add this amazing answer from crnaruka from What is outside the observable universe?EXCERPT:The best answer is that not only do we not know what is going on outside of our observable universe, but we simply can't know what happens there.To better get a sense for what I mean, let me point out that the term "observable universe" is somewhat misleading. The truth is that we can't actually observe what we call the observable universe in the usual sense, i.e. we can't watch it in real time The reason is that it takes light from a distant object at least about as long to reach us as the distance from that object divided by the speed of light. I say at least because as the light is traveling, the space it is passing through is also expanding. This expansion means that it takes longer for the light to reach us than you might expect from our initial separation to the source as shown in this diagram:It's for this reason that the edge of the observable universe is 46 billion light years way, while the age of the universe is less than 14 billion years.Following the reasoning above, what defines the "unobservable universe" is that we could never have received light from those regions. The importance of this fact is deeper than it may seem at first sight. The speed of light is not just the speed at which a wave of light ravels in a vacuum, but it is in effect a cosmic speed limit for causality.What this idea means is that not only can we not detect what goes on beyond the observable universe, but as far as we are concerned that part of the universe might as well not exist.Now to be fair, the fact the observable universe seems so uniform may make us want to extrapolate that the rest of the universe is probably similar. But in reality we just can't know. Even if much of the distant universe consisted of galactic-sized armadillos fighting for supremacy, we could never see or feel the effect of those clashes.[/EXCERPT]
What was outside the universe before the Big Bang? If it was not space, then what was it, and if it was space, then how can we say that the space of the universe was expanding?
The universe may have existed forever, according to a new model that applies quantum correction terms to complement Einstein's theory of general relativity. The model may also account for dark matter and dark energy, resolving multiple problems at once.The widely accepted age of the universe, as estimated by general relativity, is 13.8 billion years. In the beginning, everything in existence is thought to have occupied a single infinitely dense point, or singularity. Only after this point began to expand in a "Big Bang" did the universe officially begin.No one knows that the space of the Universe is “closed” , which means it will eventually stop expanding and begin to contract, or if it is “open”, which means it will stop continue expanding forever.
