Why does'nt SUN burst like a baloon and collapse?

In summary, the conversation discussed the equilibrium stage of the sun and the opposing forces of internal thermal pressure and gravity. The question was raised about why the internal matter of the sun doesn't find a way to escape and cause the sun to collapse, with the comparison to volcanoes on Earth. It was explained that the gravitational force of the sun is too strong for the internal matter to escape, leading to eruptions on the sun that are much bigger than any volcano on Earth. The difference between having a doubt and a question was also clarified.

Dear friends ,I have the following doubt:
We know our SUN is in a stage of equilibrium having an internal thermal pressure and opposing gravitational pressure.
Why doesn't internal matter find ways through matter of sun and get released out to collapse the sun.

When the internal matter goes outwards it is not internal anymore and gravity acts on it too.

Can it not escape like volcanos on earth?

There are eruptions on the sun that are bigger than EARTH, not just bigger than eruptions on Earth.

gianeshwar, the gravitational force of the sun is massive. That's how stars work.

By the way, you did not have a "doubt", you had a "question". They are not the same:

To have a doubt about something means you think it might be wrong. You are not ASKING anything at all, you are stating a fact; the fact that you think something might be wrong.

To have a question means you do not understand something and would like information.

Thank you all friends,I am continuing to think and learn...
 

Related to Why does'nt SUN burst like a baloon and collapse?

1. Why doesn't the Sun burst like a balloon?

The Sun does not burst like a balloon because it is held together by its own gravity. This gravitational force is strong enough to counteract the outward pressure from the Sun's nuclear fusion reactions, keeping the Sun stable and preventing it from bursting.

2. What would happen if the Sun were to suddenly collapse?

If the Sun were to suddenly collapse, it would become a black hole. This means that its gravity would become so strong that even light could not escape from it. However, this scenario is highly unlikely as the Sun does not have enough mass to become a black hole.

3. Can the Sun ever burst or explode?

The Sun will eventually die and expand into a red giant, but it will not burst or explode. This red giant phase will occur in about 5 billion years and will be caused by the depletion of hydrogen fuel in the Sun's core.

4. What keeps the Sun's core from collapsing?

The Sun's core is kept from collapsing by the constant fusion reactions that occur within it. These reactions produce a tremendous amount of energy, creating an outward pressure that balances the inward pull of gravity. This balance of forces keeps the Sun's core stable and prevents it from collapsing.

5. Could a powerful enough explosion cause the Sun to burst?

No, even a powerful explosion would not cause the Sun to burst. The Sun's internal structure and the balance of forces within it are too strong to be disrupted by an external explosion. The Sun's size and mass also make it highly resistant to any external forces that could cause it to burst.
