But it is a mathematically inevitable consequence of the Einstein field equations. A singularity develops.

But in a funny way, you can never observe the singularity and then bring that information back out ("no naked singularities"). So how are you going to do an experiment to demonstrate there's a singularity? You really can't, you get spaghettified and hawking-radiated out a bajillion years later.

This is part of what Penrose and Hawking are famous for! Singularities are guaranteed en.wikipedia.org/wiki/Penrose...

I can't remember where I read good non-technical accounts of this... Probably Susskind's Black Hole Wars. Hawking's autobiography is good but I can't remember if it discusses this.

(oops, also you need vanishing diffusion term to get the sharp cusps)

The KPZ equation is very cool. In the simple case with no noise term, its solution is patched downwards pointing parabolas. I'd like to get a pic where those sharp cusps develop over time but where you can still see some effect of noise like in this pic, but I can't find the right params atm.

If you like that, you might like this challenge codegolf.stackexchange.com/q/214638/53884 based on OEIS sequence oeis.org/A337517 (the number of distinct resistances that can be produced from a circuit with exactly n unit resistors.)

Oh awesome! Might try my hand. I used some of the code from oeis.org/A048211 which is slightly different. Actually a(5) is the first different number, so I wonder what the unique circuit with 5 resistors that obtains a new value (not obtainable by series and parallel circuits) looks like.

I used slow mathematica code, you have to go to 14 resistors before you can do better than 22/7. I basically just check N cases where N is taken from oeis.org/A000084
