Single Idea 19952

[catalogued under 27. Natural Reality / E. Cosmology / 7. Black Holes]

Full Idea

Black holes have a temperature, and hence entropy. ...But if a black hole are just an extreme scrunching of smooth space-time, it should have no substructure, and thus no entropy. This is probably the most obvious incompleteness of general relativity.

Gist of Idea

Black holes have entropy, but general relativity says they are unstructured, and lack entropy
