No, there are two main options for the future of the universe. It can either stop expanding and begin to contract - resulting in "the big crunch". Or it can continue to expand for ever more - resulting in the big black-out (when other galaxies are so far away and their light so faint that the sky becomes dark. Which option is more likely seems to depend on the amount of dark matter and dark energy and nobody is quite sure how much of those exist.
In any case, all this is academic for humankind. If they have not managed to destroy earth through their callous disregard before then, the sun is expected to become a red giant in around 4 billion years. At that stage its outer layers will contain or reach the earth's orbit. So, by then, the earth will really experience global warming!

In the big bang theory what describes a universe that will stop expanding and begin to contract?
A closed Universe.
Will the universe ever begin to contract?
It doesn't seem so. There is evidence that the expansion is accelerating (the Universe is expanding faster than in the past). The reason for this is still somewhat of a mystery; do an Internet search on "dark energy" for more details.
Where does every piece of matter begin in the universe?
The best theory is that all matter was created at the Big Bang
What fundamental forces pulled together hot dense areas of matter in the early Universe to begin the process of star formation?

How did the big bang theory propose spreading out from the center?
Your question shows a basic misunderstanding of the Big Bang, common even amongst scientists and fostered by popular mis-representations. Our Universe did not begin with an expansion from a center point. In particular, it was not an explosion of matter into empty space. Instead, it was an expansion of space itself, in which matter came along, becoming less dense as space expanded. There was no center point from which space expanded; all points in our Universe expanded away from all other points in exactly the same way. If this were not the case, then the strenfth of the cosmic background radiation would have a preference in direction. Instead, the CBR is isotropic to one part in 10,000. The best way to envision our expanding Universe -- and even this way has its flaws -- is to think of space as the surface of an expanding balloon, with matter and galaxies like ink dots on this surface. You'll notice that no point on this balloon's surface has any right to claim itself as the center of the expansion; all points are simply moving away from each other. The problems with THIS viewpoint is that space (ie, the balloon surface) is viewed as (1) expanding INTO something, (2) two-dimensional, and (3) curved -- whereas space in our Universe is instead not expanding into anything, three-dimensional, and (as best we can tell) mathematically "flat." If your actual question is "Why did space start to expand about 13.7 billion years ago?", the answer is that we don't know yet. We're pretty much like Johannes Kepler when he observed that planetary orbits were eliptical -- we know this to be true, we just haven't found out what's causing it.

Why is the mass of the universe important in predicting the future universe?
If there is not sufficient matter in the Universe, eventually, entropy will take over and the Universe will continually expand and cool until there is no possibility of life. If there is enough mass, the Universe will eventually begin to contract on itself, leading to a Big Crunch, from which the cycle my begin again.

Why does the height of space increase?
The universe is at an expansion stage as visible now. Space is increasing faster than the speed of light. This can be explained by the Big Bang Theory because when the big bang occured space was sent flying in all directions at relativistic speeds. It has also been theorized that the universe at one point will stop expanding and begin to diminish.
What questoin is most commonly asked?
How do the universe begin is the most asked question, because their is no answer. Their are many theory's to this volcano, meteor or god and many many more! ANSWER: "How did the universe begin"
When and how did the universe begin?
The Universe is generally believed to have started very small, very hot, and very dense; from there, it expanded to its current size (and it continues expanding). This hot and dense beginning, generally known as the Big Bang, was about 13.8 billion years ago.
