What else can I help you with?
What force causes nebula to collapse?
Gravity is the force that causes nebulae to collapse. As particles within the nebula are pulled together by gravity, they begin to clump and form denser regions. This leads to the eventual formation of stars and planetary systems within the collapsing nebula.
How do gravity and pressure keep a nebula from collapsing?
Gravity pulls the particles in a nebula towards the center, trying to collapse it. However, pressure from gas and radiation within the nebula counteracts gravity, creating a balance that prevents collapse. This balance is crucial for the formation of stars from a nebula.
What force is responsible for crushing or collapsing stars?
A supernova is caused the the fusion of (in most cases helium) molecules in iron. Once you reach iron, you can't use fusion. Thus, the star can't produce the energy to keep it stable and gravity causes it to collapse.
How do stars keep their spherical shape?
Stars maintain their spherical shape due to the balance between internal pressure pushing outward from nuclear fusion reactions in the core and gravity pulling inward. This equilibrium creates a stable equilibrium that keeps the star from collapsing under its own gravity and helps to maintain its rounded form.
Did gravity form stars?
Yes. Stars form when clouds of gas and dust, called nebulae, collapse under the force 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.
What does the equilibruim between the outward pressures of radiaion and the force of gravity do?
While the star can produce energy, that keeps the star in balance - it keeps the star from collapsing. By the way, another outward force is the gas pressure, but that, by itself, is not enough to counteract the force of gravity in the case of a star.

"While the star can produce energy, that keeps the star in balance - it keeps the star from collapsing. By the way, another outward force is the gas pressure, but that, by itself, is not enough to counteract the force of gravity in the case of a star."
Which pulling force do planets and stars have?
Planets and stars have gravity.
What type of force prevents objects from getting lost in space?
Gravity is the force that prevents objects from getting lost in space. It keeps objects like planets, stars, and spacecraft in their orbits around larger celestial bodies like the sun. Without gravity, objects in space would continue in a straight line forever.
What force creates a star?
Gravity is the force that causes stars to be created
What force is responsible for crushing or collapsing stars?
A supernova is caused the the fusion of (in most cases helium) molecules in iron. Once you reach iron, you can't use fusion. Thus, the star can't produce the energy to keep it stable and gravity causes it to collapse.
Which force drives the formation of new stars?
Gravity
What force is responsible for holding the stars gases and dust together in a galaxy?
The answer is simple: gravity.
How do stars keep their spherical shape?
Stars maintain their spherical shape due to the balance between internal pressure pushing outward from nuclear fusion reactions in the core and gravity pulling inward. This equilibrium creates a stable equilibrium that keeps the star from collapsing under its own gravity and helps to maintain its rounded form.
