The inward force of gravity is counteracted by two outward forces: gas pressure, and radiation pressure. Once the star runs out of fuel, the radiation pressure stops, the gas pressure is no longer enough to counteract gravity, and the star collapses - into a white dwarf, a neutron star, or a black hole, depending on its mass.

How does gravity affect the stars moon an planets?
Gravity keeps the planets in orbit around the sun and the stars and the stars in orbit around the center of the galaxy. Gravity also holds the stars together against their own internal pressure.
Did gravity form stars?
Yes. Stars form when clouds of gas and dust, called nebulae, collapse under the force of gravity.
What would happen to stars if there was no gravity?
If there were no gravity, period, there would be no stars. If gravity ceased to work, there would be a whole lot of violent explosions as the nuclear, mechanical and other forces within the stars popped the stellar balloons, so to speak.
Describe how gravity causes stars to form galaxies?
It depends on how much gravity that causes stars to form. It depends on how big the star in the galaxies is.
What are stars in the sky held together by?
gravity
Is there gravity inside you?
No, gravity is not inside us. Gravity is a force that acts around us. Everything in the universe has gravity. I am not sure about stars that weigh negative (e.g -500g) I guess that they would have a reppling force.
Are stars rounded by gravity?
yes because they levitate in space gravity does hold stars up
Do stars twinkle due to refraction or gravity?
Stars in the universe twinkle because of refraction not gravity.
What gives you balance?
gravity
Is there a balance between pressure and gravity in main sequence stars?
Gravity is constantly pulling the matter of a star together, while the nuclear fission reaction that makes the star shine and put off heat is trying to make it explode. The two are very precariously balanced.
What can upset the balance between gravity and pressure in a nebular?
You used the term nebular. I take it you mean a galaxy. There would not be a balance between gravity and pressure. There would be a balance between gravity and centrifugal force.
What happens to a person's balance if his center of gravity is lowered?
The lowering of the center of gravity will make it easier for the person to balance. The person will use less muscular energy to maintain his balance with that lower center of gravity.
How are stars made with no gravity?
They aren't. Stars form as a result of a cloud of gas collapsing due to gravity.
How does gravity affect the stars moon an planets?
Gravity keeps the planets in orbit around the sun and the stars and the stars in orbit around the center of the galaxy. Gravity also holds the stars together against their own internal pressure.
Inside a star the force of gravity is balanced by?
If the force of gravity crushing a star in weren't balanced, it would collapse. The outward-pushing force counteracting gravity is the energy produced in nuclear fusion, when the heat and pressure inside of stars smashes atoms together.
What force is responsible for the birth and death of stars?
Gravity, in both cases.Gravity, in both cases.Gravity, in both cases.Gravity, in both cases.
Which pulling force do planets and stars have?
Planets and stars have gravity.
