General relativity says that matter warps space and time; black holes are simply very dense agglomerations of matter. But simple it isn’t. General relativity’s equations fail catastrophically ...

Stephen Hawking and Jacob Bekenstein calculated the entropy of a black hole in the 1970s, but it took physicists until now to figure out the quantum effects that make the formula work ...

Kerr/CFT Correspondence: A theoretical framework that relates the properties of rotating black holes to those of two-dimensional conformal field theories. Bekenstein-Hawking Entropy: The entropy ...
