the universe is finite yet has no edge and no center. it is four-dimensional, but if you can imagine a two-dimensional version then it seems to be something like the surface of a sphere, and it is this surface that is expanding. nothing, not even space-time, exists "outside" the universe. to quote a dead writer, "there is no there, there". the big bang was not an explosion of matter in empty space. the big bang was the entire universe, and everywhere in the universe was once the big bang.

Our universe is actually a bubble expanding at the speed of light. This bubble exists in what is thought to be a "multiverse" made up of lots of hyper space with other universe "bubbles".
Our universe ends at the edge of the bubble. It is weird-- as if it were a recording of everything that happened. If you were to somehow go there, you would be going back in time and see the big bang because that is what made up the first part
Hyperspace is something we don't fully understand. In theory, it is infinite. But, since we can't observe it -- who knows.

The concept of space and time is within the universe. Beyond (out side) the universe the concept of space doesn't apply. Hence the question 'where?' is inappropriate. If you are keen, read the book 'A Brief History of Time' by Hawkins which answers all your questions without involving maths

think of the millions upon millions of solar systems that make up a galaxy. Then think of how galaxies form clusters and super clusters to form the galazy. Is it really so inconceivable that perhaps the universe (possibly universes) works on the same principle. That there are an infinate number of universes out there just like there is an infinate number of stars. What if the universe joined with a hundred more universes to form a local cluster of universes that is part of a super-cluster of universes? The question then becomes. What's larger that the Universe?The Omniverse?
Just my Theory... but I was laughed out of my University astronomy class.

everything lies in the universe. space, time and energy, even light lose all their finite meanings when we talk about the universe. Their is no end to the universe becauz nothing lies beyond it. And it can't expand anywhere becauz nothing lies beyond it. Ok.

It depends upon what you mean by the universe. It looks tha tat times the scientists mean the space and all the galactic matter in it . At imes it seems that they refer to the glalctic matter alone.
Excepting the matters that could be calculaed like motion of the galactic bodies , the existence of the free energy particles of free elctrons and protons , the electro- magnetic forces , x-ray ,micro waves , radiation , light , the rate motion of the bodies and their approximate distance from each other and from the earth , the rest of the propositon relating to the origin and creation of the universe etc are based on assumptions.
Some say that initially hter was nothing .This statement does not seem to e scientic. just imagine a situation , there being "nothing" no matter and and no space. A situation where ther is no "Emptiness " - No space .Such a position could never exist under any circumstances.There should have been at leat some emti space . Secondly no matter could ever come into being from nothing . The matter should have come from some mater that was invisible and wide-spread . The electro magnetic forces and the free elctron and proton oparticles which can be seen only through electron microscope and which are the building blocks of all matters, in the universe should have been there . The invisible matters being acted upon by the forces of energy like llightening , electromagnetic forces , microwaves etc should have been responsible for the creation fo all matters in theniverse. We know cold condenses and shrinkls everything . The space is known to be highly clod . Even while we travel by a plane withing the atmospher of the eath , the out side temperature is several degrees below zero . In the depth of the vast space it should be even now extremely cold . Becase the space is enormously vast and ther is not enough matter to fill the entire space. But for the vast emptiness of the space there would be no possiblity of the moving at all. The intitially the primordial matter shoulkd have formed by the condensation od the invisible matter , the basic components of which all matters in teh universe are made of .( the electrons , nutrons etc ) . The very theory is predicted on the basis of the fact that the maters in the glaxies around us ar moving away from one another at
the same rate of speed in such a way that they should have been scattered away by a big bang from one particular point .So mathematically they arrived at a point to conclude that the primodial mater was an atom..since the moving matters that came into being from the primordial matter is so huge , they presume that the whole matter should hav bveen condensed with infinite intensity in teh atom. It is here that mathematics deviates form common sense and known laws of physics. First and fore most noi amount of cold could hav condensed the entire mass of the univrse ( that is all the matter contained in all the galactic bodies ) in a single atom.. mathematics can even take it back to say that ther was minus matter beyond the point of the atom to which they have come by calculation.. it is just like saying tha a car that is travelling at 100 miles per hour and seen at some 3oo miles should have travelled some 3 hours from the point of starting and could have starte and tha tit had zero speed at the time of start and therfore it did not existed and that befor 3 hours bvefore the time of the start ,it could hav been some 300 miles away form the point of start .It may bve mathematiclly right ; but preacticall not .
It is also stted by scientists that they do not know what caused the sudden expansion (Big Bang ). We know that according to physical laws compression reduces the volume of anysubstance to a certain level and that the reduction in volume would increse the desity of the matter and tha the increase in compressive pressure would increase the friction among the molecules and atoms of the substance and at a certain levekl it would cause the substance to burn and explode . The intital and basic atoms being those of gases it can eeasily presumed that the intial reaction should have been an explosion only . that is the only reason for the galactic bodies moving at tremendous speed away form the from the point of explosion.. It is just like thescattering of the coins place at the center of a carrom board being struck with tremendous force by astriker .thjeydo not expand . they scatter . To say th the space also came into bing out of the primoridal matter is in correct . space is prerequisit for any thing to exis t or come into being . matter itself however samll or invisible it is can not exis withour space . No motion is possible without space. Space being emptiness , it has no shape , no boundery and no matter . un fathomable . it is the only thing of unique and absol;ute chatacter . Nothing can act on it . It can exist without anything in it . it does not require a the assistance of anything for uits existence ; but nothing can ever exist without space . It neither shrinks nor expands as it is "nothing " void ' emptiness ". All the galactic mater lie in it and move in it and exist in it . No space - No matter ..space is neither created notr destroyd - so is matter . it is neither created nor destroyed . but matter is mutable - but space alone has the unique character of immutability.- inconceivability.
the scientist can find outr the origin and nature and evn the quantum of the solidified galactic matter . butr man will never be able to predict o even conveive the origin of the empty space . We know that we hav a face . we would never be able to see our real face except its image .When a microbe SITTING on the body of an elephant is able to see the whole elephant ,we would albe to see the whole space! If It is has a boundry , then there should be somethng beyond a boundary and some thing beyond it and so on.; but emptiness alone can be with out a boundary . That is the unique and absolute and inconceivable nature of the space that sustains the entire universe .It has not boundary - limits and so nothing lies beyond it .we can oly think og things with boundaruies and limits
.
Man with his limited knowledg and short span of life is try ing to unravel the mystery that the Great natural forces hav taken zillion of years to just reach this little stage . May be natue itself has to go a long way to prefect its business of creation,anihilation and re-creation .the universe , if you mean the glactic matters , lies in the vast emptiness of the wonderful un -ssuming being of non-being , the space .and if you include the space alos tomean w universe , it lies in itself and not in anything else . Ther is no question of beyond anything beyond the space , because emptiness needs no boundry and exists withur boundary . Everything else in the universe has a boundary and need a specific volume of space to exist . But space does not requireanything to exist in. The human brain having been conditoned by the closed environment
and controlled and acted upon by the forces of gravity and electromagnetic forces can not conceive of somethig that is beyond the powers of the naturl forces - some thing that sustains the naural forces- something on which no natural force can ever have any effect. We may come to know of the unique nature of this "Nothing ness' one day!

gravity and matter do not exist in a vacuum
the vacuum was infinite, the universe filled it, the universe is infinite, the vacuum does not exist now
in reality, the universe is infinite so, there is no place and it does not end
it is harder to percieve and makes you feel less safe but, think of the endless opportunities
why is it easier for humans to imagine an ending than no ending

Now consider that the Universe, as an absolute frame of reference is
in a condition of T = 2,7K (rests relic radiation of the Big Bang ).
But, the relic radiation is extended and in the future will change
and decrease down to Т=0Ð.
The Universe lie in T=0K.

There doesn't need to be ANYthing beyond the universe and, by definition, there isn't. Though our senses trick us (lie).
