LIGO BH Merger & Black Hole Information Paradox

Click For Summary
SUMMARY

The forum discussion centers on the analysis of the LIGO merger detection, specifically regarding the black hole (BH) information paradox. Participants examine whether gravitational waves emitted during the merger contain information that could account for the increase in surface area of the final black hole compared to the initial black holes. It is concluded that while the final black hole exhibits a larger surface area, the gravitational waves likely do not carry significant information relevant to this increase. The discussion highlights the complexities of information retention in black hole mergers.

PREREQUISITES
  • Understanding of gravitational wave detection, specifically LIGO's methodologies.
  • Familiarity with black hole physics and the information paradox.
  • Knowledge of general relativity and its implications on black hole mergers.
  • Basic grasp of surface area calculations in the context of black holes.
NEXT STEPS
  • Research the implications of gravitational waves on black hole information retention.
  • Study the LIGO merger detection paper referenced: "Observation of Gravitational Waves from a Binary Black Hole Merger".
  • Explore the theoretical frameworks surrounding the black hole information paradox.
  • Investigate the relationship between gravitational wave energy loss and black hole surface area changes.
USEFUL FOR

Physicists, astrophysicists, and researchers interested in gravitational wave astronomy, black hole physics, and the implications of the black hole information paradox.

Has anyone analysed the LIGO merger detection http://journals.aps.org/prl/abstract/10.1103/PhysRevLett.116.061102 in the context of the BH information paradox?

Is there any evidence that the gravitational waves carried any information that could compensate for the change in areas of the initial BHs and the final BH?

The final black hole had a much larger surface area than the two initial black holes combined.

Even the orientation with the largest energy loss in GW has an increase in area. The gravitational waves probably don't carry relevant amounts of information, but they don't have to.
 
Thanks mfb I should have worked that out for myself.
Regards Andrew
