Holy Shit. It's a BEAST. Claude Fable 5.2 has solved two open problems in theoretical physics involving black holes and quantum gravity.
The first was a calculation proposed in 2003 but left unfinished for 23 years because it was too laborious. Working largely autonomously, Fable completed it and found that a phase transition associated with black-hole formation remains abrupt even in a quantum regime where classical gravity cannot describe it.
The second result established the exact limit of a technique physicists have used for over 15 years to rule out candidate theories of quantum gravity.
