What Is the Composition of Black Holes?

Click For Summary
SUMMARY

The composition of black holes remains a topic of significant debate among physicists. According to the "no hair theorem," black holes are characterized solely by mass, charge, and angular momentum, rendering them indistinguishable regardless of whether they formed from matter or antimatter. Current theories, including quantum loop theories, attempt to address the singularity issue, but they have yet to provide conclusive insights into the nature of black holes. Additionally, Hawking radiation is proposed as a mechanism for energy release, although it remains untested.

PREREQUISITES
  • Understanding of the "no hair theorem"
  • Familiarity with black hole physics
  • Basic knowledge of quantum loop theories
  • Awareness of Hawking radiation concepts
NEXT STEPS
  • Research the implications of the "no hair theorem" on black hole formation
  • Explore quantum loop theories and their relevance to black hole singularities
  • Investigate Hawking radiation and its potential observational evidence
  • Study the differences between matter and antimatter in astrophysical contexts
USEFUL FOR

Astronomers, physicists, and students interested in theoretical astrophysics and the fundamental properties of black holes.

what is the composition of black hole?
is it a matter or antimatter or energy?
 
Astronomy news on Phys.org
According to the well-known "no hair theorem", from the point of view of an external observer, a black hole has mass, charge and angular momentum and no other physical properties, so for example a black hole formed from antimatter would be indistinguishable from one formed from matter.

AFAIK, no one knows what a black hole (is) quantum loop theories try to circumvent (the) singularity, and as yet, all so AFAIK they have nothing to say about the galactic black hole.

Were can the stuff in a black hole go if it is not eternally locked up in space time?
Hawkings radiation, a so not tested conjecture.
