SUMMARY

The discussion centers on the differences between white dwarfs, neutron stars, and black holes, specifically why white dwarfs do not become black holes despite their mass. It is established that the transition from a white dwarf to a neutron star occurs when mass exceeds the Chandrasekhar limit, while the formation of black holes requires surpassing the Oppenheimer-Volkoff limit of approximately 3 solar masses. The conversation also explores the concept of primordial black holes and their potential existence in stable bound states, referred to as "holeums," which may not have evaporated due to gravitational interactions. Theoretical frameworks such as General Relativity are referenced to clarify misconceptions about gravity and energy.

PREREQUISITES
  • Understanding of stellar evolution and the life cycles of stars
  • Familiarity with the Chandrasekhar limit and Oppenheimer-Volkoff limit
  • Basic knowledge of General Relativity and its implications on gravity
  • Awareness of concepts related to black holes and neutron stars
NEXT STEPS
  • Research the Chandrasekhar limit and its role in stellar evolution
  • Explore the Oppenheimer-Volkoff limit and its significance in neutron star formation
  • Study the properties and theories surrounding primordial black holes
  • Investigate the implications of General Relativity on the nature of gravity and energy
USEFUL FOR

Astronomy students, astrophysicists, and anyone interested in the complexities of stellar evolution and the nature of black holes and neutron stars.

I think this thread's become a bit to complecated for me :frown:
Maybe I should read a good book on this subject, any suggestions?
