Discussion Overview

The discussion revolves around the question of why the Sun does not collapse like a balloon despite having internal thermal pressure and gravitational forces acting upon it. Participants explore concepts related to stellar equilibrium, gravitational forces, and comparisons to volcanic eruptions on Earth.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • Some participants note that the Sun is in a state of equilibrium, balancing internal thermal pressure with gravitational pressure.
  • There is a suggestion that if internal matter were to escape, it would no longer be internal and would be subject to gravitational forces.
  • A participant questions whether internal matter can escape in a manner similar to volcanic eruptions on Earth.
  • Another participant points out that solar eruptions are significantly larger than terrestrial volcanic eruptions, indicating the scale of activity on the Sun.
  • One participant emphasizes the massive gravitational force of the Sun as a fundamental aspect of how stars operate.
  • A clarification is made regarding the terminology of "doubt" versus "question," suggesting a distinction in the nature of inquiry.

Areas of Agreement / Disagreement

Participants express various viewpoints regarding the mechanisms of the Sun's stability and the nature of its eruptions. There is no consensus reached on the underlying reasons for the Sun's behavior or the comparisons made to volcanic activity.

Contextual Notes

Participants do not fully explore the assumptions underlying their claims, such as the specific conditions required for matter to escape the Sun or the definitions of equilibrium in stellar contexts.

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 much bigger than any volcano 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...
