When does the event horizon form?

Click For Summary
SUMMARY

The event horizon forms when a massive star collapses and reaches the Schwarzschild limit. This critical boundary signifies the point beyond which no information or matter can escape the gravitational pull of the singularity. The discussion also explores the theoretical possibility of halting the implosion by spinning the star rapidly enough, although this remains a speculative concept within astrophysics.

PREREQUISITES
  • Understanding of general relativity
  • Familiarity with black hole physics
  • Knowledge of the Schwarzschild radius
  • Basic concepts of stellar evolution
NEXT STEPS
  • Research the implications of the Schwarzschild limit in black hole formation
  • Explore the concept of angular momentum in astrophysics
  • Investigate the theories surrounding rotating black holes (Kerr black holes)
  • Study the effects of extreme gravitational fields on matter
USEFUL FOR

Astronomy students, astrophysicists, and anyone interested in the mechanics of black hole formation and the nature of singularities.

As a massive star begins it's collapse into a singularity, at what stage does the event horizon form?
 
Space news on Phys.org
When it reaches the Schwarzschild limit.
 
Is it possible to halt the implosion beyond the schwarzchild limit by spinning it fast enough?
