Will a Sun Collapse Form a Black Hole?

Click For Summary

Discussion Overview

The discussion centers on whether the collapse of the sun will result in the formation of a black hole, exploring the conditions under which stars collapse and the outcomes based on their mass. The scope includes theoretical considerations about stellar evolution and the characteristics of different end states of stars.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant questions if the sun will form a black hole upon collapse.
  • Another participant asserts that the sun is not massive enough to become a black hole and will instead end as a white dwarf.
  • A participant discusses the process of the sun's collapse, suggesting it will become smaller and denser until a certain backpressure stops further collapse.
  • It is proposed that in larger stars, the backpressure cannot counteract gravity, leading to black hole formation, while stars below a certain mass, like the sun, will not collapse into a black hole due to atomic pressures, specifically electron degeneracy pressure in white dwarfs.

Areas of Agreement / Disagreement

Participants express differing views on the sun's potential to form a black hole, with some asserting it will not due to insufficient mass, while others elaborate on the mechanisms of stellar collapse without reaching a consensus.

Contextual Notes

There are assumptions regarding the mass thresholds for black hole formation and the nature of backpressure in stellar collapse that remain unresolved. The discussion does not clarify the specific mass limit for black hole formation.

When the sun is collapsed will it form a black hole?

No, it is not massive enough. It will end up as a white dwarf.
 
When the sun is beginning to collapse will it get smaller and denser?
 
Yes it will until some backpressure will kick into stop further collapse , in large stars this backpressure can't fight back the huge mass so the gravity wins and the whole mass and all the leftovers collapse into a black hole but in mass that are smaller than the minimum limit to form a black hole they don't collapse to a black hole because the mass is not big enough for gravity to take over the pressures exerted by atoms in the case of white dwarfs - electrons.
