Maximal surface inside Schwarzschild BH

Should include a mention/review of the "famous" solution for the maximal surface inside the Schwarzschild BH. I forget the names of the authors. It's pretty cool: it grows linearly with time, and its located just a few centimeters past the horizon (for stellar-mass BH) and extends all the way back to the birth of the BH from stellar collapse.

One reason its "cool" is because ordinary physical solids are described as minimal surfaces of their boundaries. The interior of a BH has no such minimal surfaces, but it does have a maximal one and so one can say "the insides of things are extremal surfaces" and have that hold in general.
