Why do all-stars eventually die?

What causes blackholes?
Black holes happen when stars above a certain mass collapse in on themselves. After they burn through most of their hydrogen, they start burning it faster and faster until they run out of fuel. Now with out the fuel to steady the star, the large amount of mass is drawn into a tighter and tighter space because of gravity. Eventually, it collapsed into a singularity. After the singularity is formed, you have yourself a black hole.
What is the fate of all-stars regardless of size?
All stars will eventually run out of hydrogen and die.
Will All stars regardless of size eventually run out of fuel?
Yes, nothing has an indefinite amount of energy.
What is the consequence in dead stars?
A dead star would basically be one that ran out of fuel. Such a star no longer has the radiation pressure to keep it "blown up"; it will collapse. Depending on its mass, it will collapse into a white dwarf, a neutron star, or a black hole.
Explain why the sun does not collapse under the force of its own gravity?
Stars do not collapse because the inward force of gravity is balanced by the pressure generated by fusion. When stars die they do collapse. The cores of low to medium mass stars collapse to form white dwarfs. Further collapse is prevented y electron degeneracy pressure. More massive stars leave behind neutron stars, in which gravity is balanced by neutron degeneracy pressure. In the most massive stars, once fusion stops producing energy there is nothing to stop the collapse and the core becomes a black hole.

What are two types of stars that can form when a star runs out of fuel?
When a Star runs out of fuel, it will expand into what is known as a "Red Giant". Massive stars will become "Red Supergiants". This phase will last until the star exhausts its remaining fuel. At this point, the pressure of the nuclear reaction is not strong enough to equalize the force of gravity and the star will collapse. Go to related link to read more about Stars... ;)

Why do all stars eventually run out of fuel?
Stars eventually run out because when it burns the outside pushes in on the core causing it to eventually give way and implode.
What happens to stars bigger than then the sun?
When they run out of fuel they collapse and become black holes.
When a main sequence star runs out of fuel it becomes a?
Either a giant or a super giant. Giants will eventually collapse on its core and have a little white dwarf left behind, but they will have the same mass and gravity as the old star. Supergiants will collapse but in an explosion, supernova, and they will either become a nuetron star or a black hole.
What is densest?
The densest stars are neutron stars; these are "dead stars", in the sense that they ran out of fuel and no longer convert energy. However, they still have a large amount of energy left over from the collapse, which they gradually emit.
In terms of solar mass which of the stars evolves most rapidly?
Massive stars evolve the fastest.Massive stars must supply more energy to prevent collapse under their own gravity. This energy is supplied by the nuclear reactions in the core of the star. more massive stars need to burn their nuclear fuel at a much greater rate than smaller stars in order to produce enough energy to balance their much greater gravity. Therefore, massive stars will burn their fuel faster and quicker evolve from their position on the main sequence

How do stars end up in space?
Stars form in space when giant gas clouds start to clump together and collapse in upon themselves. This clumping is often caused by energy waves from nearby exploding supernova (dying stars). As they collapse, the molecules that form the clouds compress in upon each other to form helium and hydrogen. Once gravity pushes them together strongly enough, nuclear fission will begin to occur in the core of the star. This process will continue throughout the life of the star, until all of the fuel is used up.
