Paper (2022) from this post of a post: [Thermalization by a synthetic horizon](https://journals.aps.org/prresearch/abstract/10.1103/PhysRev...) (submitted last year, but no comments)

The title would be April 1 worthy, but it's just a simulation

Infuriatingly misleading title. They simulated a black hole on a computer.

It wasn't even a liquid black hole? :c https://en.wikipedia.org/wiki/Sonic_black_hole
