SUMMARY

The discussion centers on the theoretical implications of a star collapsing without forming an event horizon, challenging established concepts in astrophysics. Key points include the potential resolution of the information loss problem, conservation of angular momentum, and the generation of magnetic fields. Participants argue about the inevitability of singularities and event horizons during gravitational collapse, referencing the no-hair theorem and the Oppenheimer-Snyder solution. The conversation highlights the complexities of general relativity and the ongoing debate regarding the nature of black holes and their observational evidence.

PREREQUISITES
  • Understanding of general relativity and its implications on black hole formation
  • Familiarity with the no-hair theorem and its significance in black hole physics
  • Knowledge of gravitational time dilation and its effects on collapsing objects
  • Awareness of the Oppenheimer-Snyder solution and its relevance to gravitational collapse
NEXT STEPS
  • Research the implications of the no-hair theorem on black hole characteristics
  • Explore the Oppenheimer-Snyder solution in detail to understand gravitational collapse
  • Investigate the information loss paradox and its resolutions in modern physics
  • Study the properties of neutron stars and their relation to black hole formation
USEFUL FOR

Astronomers, astrophysicists, and students of theoretical physics interested in the complexities of black hole formation and the implications of general relativity on cosmic phenomena.

Ah, thanks - the paradox is referred to as '"the information loss problem" in the original post and, as you mention, discussed in posts 33, 35, and 37.

Regarding the resolution of the paradox, though, from what I'm reading, it has not been resolved. For example:

"To resolve the paradox, one of the three postulates must be sacrificed, and nobody can agree on which one should get the axe. The simplest solution is to have the equivalence principle break down at the event horizon, thereby giving rise to a firewall. But several other possible solutions have been proposed in the ensuing years. ...
Physicists have yet to reach a consensus on anyone of these proposed solutions. It’s a tribute to Hawking’s unique genius that they continue to argue about the black hole information paradox so many decades after his work first suggested it."

The "famously resolved" resolution you describe seems to be the one where Hawking conceded the bet. But it looks like there is still no consensus overall.
