A black hole is a region of spacetime where matter has collapsed so densely that the escape velocity exceeds the speed of light.
Known nodes connect to ghost nodes where questions remain open.
First exact solution to Einstein's field equations describing a non-rotating black hole.

The transition from semiclassical intuition to holography feels a lot like changing languages rather than solving one more equation.
I want the clearest account of why keeps showing up across thermodynamics and geometry.
