Now remember atom can potentially access all the occupancy from all other atoms in the universe. END PGP SIGNATURE- adjusted HOLE. Mac OS X on travis this. Robbert Dijkgraaf is a theoretical physicist and Leon Levy Professor at the Institute for Advanced Study in Princeton. He is also the co-author of 'The Usefu.
My question is 'what is at the end of the universe if it really does end?' because if the big bang theory is correct then then when the whole universe was one atom or very small what did it expand into because if there was nothing there it couldnt have expanded. for example if you have a room and you say that the walls are the end of the universe then you build on to the room to make it bigger (the universe expanding) there has to be room on the other side of the wall for you to build into.
There is nothing called the end of the Universe. There are three possibilities of the shape of the Universe.
First, the Universe might have what we call positive curvature like a sphere. In this case, the Universe is called 'closed' and it has a finite size but without a boundary, just like a baloon. In a closed Universe, you could, in principle, fly a spaceship far enough in one direction and get back to where you started from.
The second possibility is that the Universe is flat. This kind of Universe can be imagined by cutting out a piece of a baloon material and stretching it with your hands. The surface of the material is flat and not curved. You can expand and contract it by tugging on either end. Flat Universes are infinite in extent and have no boundaries.
Finally, the Universe might be 'open' or have negative curvature. Such Universes are also infinite in spatial extent and have no boundaries.
- The Hole in the Universe: How Scientists Peered over the Edge of Emptiness and Found Everything (2001) Nothing exposed for what it is: Something! This is a book about 'nothing' inspired by recent discoveries in physics, similar to the one written by Brit physicist John D. Barrow, The Book of Nothing: Vacuums, Voids, and the Latest Ideas about the Origins of the Universe (2000).
- Frustration with this hole in the product line reached a boiling point in 2017 when the 'days since the Mac Pro was updated' became a running joke on technology blogs. The Mac Pro became so old that off-the-shelf, middle-of-the-road consumer hardware was faster, and pros simply had nowhere to go.
Thus whatever be the shape of the Universe, there is nothing called a boundary and hence nothing called the edge or end of the Universe.

Regarding the second question of expansion, remember that space exists only IN the Universe and there is no meaning to the term 'outside the Universe'. What happens in expansion is that the space itself is expanding. With respect to your room analogy, it is not that the walls of your room are pushing against something but that the space in the room is expanding; there is nothing to push against. Thus, when we talk of galaxies receding from us due to the expanion, it is not that the galaxies are moving, but the space in between us and the galaxies is expanding.
Edit by Michael Lam on February 10, 2016: Recent observations suggest that the Universe is very close to flat. The WMAP mission determined that it is flat to within a 0.4% margin of error.
Humans usually have a hard time dealing with the fact of how their life is very much finite. You never know the exact expiration date, but you are sure it will happen one day. The same goes when we try to understand concepts that go well beyond the notion of time, from a human and a mortal perspective.
Infinity is something that is equally hard to deconstruct. When we talk about the size (and time!) of the universe we live in, we are faced with the same problems. Where does the universe end, and does it actually have an end?
Understanding Our Time-Space (Dis)Continuum
First of all, from the current dominant cosmological theories - yes, our cosmos indeed does have an expiration date. There are many theories that tackle the ideas that explain the end of the universe. If you want to put things into perspective, that is not something humankind will ever witness, at least not on this planet or this universe.
If, and this is a big ‘’if’’, we find another place to live, one that is far away from our Sun (who is going to die in 5 to 7.5 billion years from now), then we might have a chance to witness the collapse of one universe and the potential creation of others. The Big Rip theory, for example, suggests how in 22 billion years, this universe will rip itself apart because the overall gravity potential will not be able to hold off the expansion power of the universe.
Is The Universe Expanding Forever?
The Big Rip theory, despite the fact that it is explaining the end of time and space as we know it, tells us something super critical about the nature of the universe. This one feature makes it almost impossible to know where space ends. You guessed it - it is expansion. From the day that all the dense matter blew up (do not worry if you do not remember this event, the Big Bang was 13.8 billion years ago), the universe started expanding.
As stars, planets, and galaxies were formed, they immediately started moving. From where you might ask? Well, obviously - from the center of the explosion. The problem lies in the fact that we do not know where the center is, and if there was a center in the first place. However, the fact we mentioned remains unquestionable - the galaxies are moving away from each other.
Observable Vs. Unobservable Universe

We know all of this because we can observe space phenomena and interactions between such massive space formations from Earth. This is the second crucial thing to understand if you want to address the idea of space and its borders. The telescopes we use are limited as to how far they allow us to see.
Currently, modern-day telescopes allow us to see the universe that surrounds us within a 93 billion light-year diameter. Whenever you hear someone saying that is how big the universe is, he or she is just referring to the area we can see. This is known as the observable universe: Earth is a center point, and we can see galaxies 46.5 billion light-years away, in any direction we look at.
Edge Of The Universe
However, what lies beyond the galaxies we can not see? Is there another universe that makes all of the multiverse theories plausible? Or, is there nothing beyond the final expansion point we currently can not even see? It is hard to tell because all of this raises an indefinite number of questions that try to organize the cosmic chaos we are stuck in. The idea of how there is nothing beyond comes down to an almost religious, and a moral one, as humans have an equally hard time dealing with the notion of ‘’nothing-ness’’ the same way the can not wrap their heads around ‘’infinity.’’
