Will analogue black hole systems reveal quantum gravity?

WebbNational Center for Biotechnology Information WebbYes, black holes emit a little amount of radiation called Hawking Radiation (named after the discoverer). 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). the puppy place liberty

A black hole’s “surface,” called its event horizon, defines the boundary where the velocity needed to escape exceeds the speed of light, which is the speed limit of the cosmos. Matter and radiation fall in, but they can ... significant events in the noughties

"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. " - Theoretical boundary around a black hole
