What happens after matter reaches point of cingularity?

No one knows because the concept of Singularity is metaphysical and not supported by the laws of physics or math.

No way to know.  What is the shape of "everything"?  I think it is round and that if you go to one end, you'll end up back at the same point if you keep going the same direction.\n\nGood question.

Nothing, in a logical sense of the word.\n\n\nThis is similar to the question, "OK, the universe is expanding, what is it expanding into?" Both questions are based on analogies which are designed to help us think about complex situations. They tend to be ones where we think of the universe as being something like the surface of an inflating beach ball which is being blown up. Our image of the "beach ball universe" includes space to expand into.\n\nThis is a limitation of the analogy, not the actual universe. The details of General Relativity describe the "shape" of the universe and how gravity effects different parts. GR works on the scale of galaxies and galaxy clusters. For smaller scales, dropping a pencil off your desk for instance, Newton's Gravity is fine. (GR turns into Newton's Law of Gravity at small scales.)\n\nOur brains are simply not designed to imagine curved space with all three spatial dimensions. To get around this the analogies use two-dimensional universes. But the analogies can't be taken too far. In this case, the only way to really understand deeply the structure of the universe is by understanding the mathematics. There is no exact mental picture.\n\nSo, the question has no answer, and in fact, logically speaking, makes no sense. (That isn't to say it is not a sensible question, it is a sensible question.)\n\nThe usual example of such a question is: "What is north of the north pole." Once one gets to the pole there is no more North. Everything is south. So asking what is north of the north pole is (logically) a nonsensical question.

the univesre is finite and unbounded.\nthat is at this particular moment matter and radiation exist till some position and not beyond that, that is there would be places where nothing has reached yet, this can be thought of as some kind of boundary. but this boundary keeps expanding with time.

all matter, which moves in time, decreases over time

In all actuality, your question makes no sense.  If you were to take out all the "space" in matter, there would be no matter.  Matter is basically made out of energy and forces interacting with each other.  If you compressed the universe into the size of a refrigerator, you wouldn't have matter anymore.

Well, as far as we know, all the matter that gets sucked in gets crushed into a single point with zero dimensions. As in, a point with no length, width, anything. This is called a singularity.\n\nOr, another theory is that there are wormholes. If you get sucked in a black hole and survive (heh...not likely), you get thrown into a different part of the universe, or another universe, or another dimension, or whatever. However, the wormhole theory is losing support as of now.

Probably find a ship graveyard.\n\nNo...for real...I don't think it is possible to reach the edge of the universe.\n\nPrint this out, then if it happens, you can say, "I told you so."  :)

An interesting theory!  What do you think it will start coliding with?  Actually as space expands, the matter within it becomes farther and farther apart, so there is less and less chance of colisions.  \n\nThere are two aspects of the curvature of space.  Local curvature is caused by (or causes) gravity - masses curve the space around them.  But the entire universe may be curved on a great 4-D sphere.  \n\nThe third link below gives an excellent discussion on curvature and the expansion, including an explanation of the density parameter.  If the density parameter is less than 1, then the universe will expand forever.  \n\nAstrophysics and cosmology are pretty fascinating topics.  Keep asking questions and, when the time is right, take some classes in these subjects (take lots of math first!).  The scientific world needs folks who can think outside the box!

You misunderstand the Big Bang theory. The universe did not start from a big ball of matter. For the first 10-34 seconds we simply don't have the physcis figured out as to what happened. There are many conjectures, though.\n\nThe first difficulty is that General Relativity predicts something called a singularity at the Big Bang. A singularity is something like what you see at the north pole. There is no 'north of the north pole' simply because the coordinate system can't be extended that way. Under General Relativity, there is no 'before the Big Bang' because thw time coordinate cannot be extended past that point. Remember that time itself is part of the structure of the universe, so time began when the universe did (in this view).\n\nAnother view is obtained through quantum mechanics. We know that modern vacuums are never completely empty. They are a blur of particles apperaring and disappearing all the time. The state of having absolutely nothing is actually a very high energy state. When that state decayed into a lower energy state, that provided the energy that subsequently became the matter we see around us. In this scenario, the singularity predicted by relativity is blurred out by the quantum effects, but the net result is that all the matter literally came out of a vacuum. This is possible without violating conservation of energy because the vacuum state 'befroe the Big Bang' had a higher energy than all the matter we see around us.\n\nAnother possibility is a 'bouncing universe' where the universe goes through cycles of collapse and expansion. The collapse before the current cycle provided the energy for the current one. There are modifications to this where 'universes' bud off of the vacuums of other ones.\n\nAll of this is highly speculative. However, we do know that a Big Bang is how things got started about 13.7 billion years ago. We see the afterglow of the hot, dense time at the beginning all around us in the cosmic microwave background radiation (CBE).

i think the problem is when you try to apply general relativity - or gravity - to interaction betwen subatomic particles - especially when trying to understand how these forces worked during the first instant after the big bang. you wind up with nonsencial results - like zero equals one.

I have given an answer to this elsewhere, but I will repeat it here.\n\nAssuming that by the question you ask, you are essentially asking what is beyond the edge of our Universe, the answer to which will change depending on whether we live in a flat, open or closed Universe.\n\nOne way to try to understand it is to throw away a dimension, and imagine being a 2 dimensional being living on a sheet of paper. Sort of like a cartoon that you drew. To them, the Universe they occupy consists of only the paper itself. There is only up/down, left/right, there is no in and out of the paper for them, it may exist for us observing them, but they can't see us, and they are not aware of this extra dimension. Living on this sheet of paper, whilst flat on the desk there is quite obviously an edge beyond which to them, is nothingness...... hmmmm\n\nOk, so now imagine that they aren't living on a flat piece of paper but on the surface of a sphere (say of a baloon for example). The inside and outside of the sphere is a dimension inaccessible to them. Therefore, there are now NO edges to their universe. If they travelled upwards from their position (NOT leaving the sphere), then they would eventually come back to where they started. If you then started to inflate the baloon, it would expand, but to the "cartoon" people, all they will experience is seeing their surroundings expand. To them, their universe is expanding into another dimension, that they cannot see, and that it inaccessible to them.\n\nThis in a way, but with one dimension less, could be what is happening to our Universe. There may be no physical edge that we can ever come across, but it could be expanding into another dimension. \n\n\nOn the other hand, if you are asking if the Universe will, one day, simply cease to exist .... then that is a completely different answer!!!!\n\nThe Universe is expanding - into what, could be another dimension - and the amount of matter in the Universe will determine whether or not this expansion will stop and reverse, or whether it will carry on for eternity!  As it happens there is evidence to suggest that the expansion of the Universe is actually accelerating, and so the end of the Universe will be a very dismal cold place.  There will be no stars left giving out light, the heat of the Universe will be stretched out over infinity!  It will be the death of the Universe.\n\nIf there was enough matter in the Universe then the gravitational pull of all the matter could force the Universe to start to collapse back in on itself. Eventually it would all come together in one place in what would be called "The Big Crunch" - and this would be the end of the Universe as we know it.

It's either God created it or it created itself. After the big bang, matter might have packed and packed together due to gravity. It packs itself, and pulls itself. As it becomes more dense, the center or core becomes hotter and hotter. The denser materials descend to the core, such as iron. Then at the surface, it's cool since it is exposed to space and is far from the core.

well if it were in a medium where it is obstructed by external forces,it would continue till the 0 point and stop... but when unobstructed it would keep travelling.

The expansion happens everywhere, but things that are bound together even moderately, do not experience it reletive to what they are bound to.  You don't notice it in the solar system, our own galaxy, or even the local galaxies near by.  This is because the gravitational force is enough to overcome the exansion.\n\nSimilarly you don't exapand (due to chemical bonds), and electron orbits, governed by QED (advanced form of electromagnetism) don't change their size.  In a sense you will only notice it with objects that you are basically unconnected with.\n\nWe don't notice the cosmic expansion until we either look at galaxies and objects very far away, or look at light that has traveled vast distanced before it reaches us.
