Discussion Overview

The discussion centers on the formation of white holes, exploring whether they can occur naturally or if they are purely theoretical constructs. Participants examine the relationship between black holes and white holes, as well as the implications of thermodynamic laws on their existence.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant questions how white holes form if black holes typically arise from stellar collapse.
  • Another participant notes the lack of observational evidence for white holes, emphasizing that none have been seen.
  • A participant argues that white holes are theoretically the time reverse of black holes and suggests their existence is prohibited by the second law of thermodynamics.
  • Another participant asserts that without credible observational evidence, the existence of white holes in our universe remains unsubstantiated, highlighting that theoretical possibilities do not guarantee physical existence.

Areas of Agreement / Disagreement

Participants generally disagree on the existence and formation of white holes, with multiple competing views presented regarding their theoretical status and observational evidence.

If black holes usually form when stars collapse, how do white holes form?
 
Space news on Phys.org
Nobody has ever observed a white hole.

A white hole is the time reverse of a black hole, and is thus forbidden due to the second law of thermodynamics.

To put it another way, we aren't going to be seeing any white holes out there for the exact same reason that we won't see scrambled eggs unfry and hop back in a shell.
 
Other universes? Seriously, there is no credible observational evidence of a white hole in this universe. That is the gold standard. Not everything that appears theoretically possible is known to physically exists in this universe.
