Neutron Star Becomes Black Hole: How Can 2 Realities Coexist?

Click For Summary
SUMMARY

The discussion centers on the coexistence of two realities regarding neutron stars and black holes, specifically how relativistic effects like length contraction influence their gravitational properties. Participants clarify that the stress-energy tensor in general relativity governs gravity, not just mass or density. The Schwarzschild radius is emphasized as applicable only to stationary masses, while moving masses require more complex solutions, such as the Aichelberg-Sexl ultraboost. The conversation concludes that relativistic effects do not alter the fundamental nature of black hole formation, which remains invariant across different inertial frames.

PREREQUISITES
  • Understanding of general relativity and the stress-energy tensor
  • Familiarity with the Schwarzschild radius and its implications
  • Knowledge of relativistic effects, including length contraction
  • Basic grasp of Einstein's field equations and their solutions
NEXT STEPS
  • Study the implications of the Schwarzschild solution in general relativity
  • Explore the Aichelberg-Sexl ultraboost and its applications
  • Investigate the role of the stress-energy tensor in gravitational physics
  • Learn about numerical solutions for dynamic masses in curved spacetime
USEFUL FOR

Physicists, astrophysicists, and students of general relativity seeking to deepen their understanding of black hole formation and the effects of relativistic physics on gravitational phenomena.
