Theoretical boundary around a black hole

Webb11 juni 2024 · By exploring more than sixty thousand quasars from the Sloan Digital Sky Survey Data Release 5, Steinhardt & Elvis discovered a sub-Eddington boundary and a redshift-dependent drop-off at higher black hole mass, possible clues to the growth history of massive black holes. WebbIn this context, we will also derive boundary conditions that couple boundary and bulk degrees of freedom and show equivalence to the results found in the D’Auria-Fré approach in context of the non-chiral theory. These results provide a step towards of quantum description of supersymmetric black holes in the framework of loop quantum gravity.

This radiation comes directly from the black holes mass and the black hole slowly gets smaller overtime. This takes an extremely long time though. The average stellar black hole will take an incredible 10^66 years to decay (10 with 66 zeroes).

WebbThe telescope is named after the “event horizon”, the boundary of the black hole beyond which no light can escape.
