Extremal black holes are exceptional solutions of Einstein’s equations which have absolute zero temperature in the thermodynamic analogy of black hole mechanics. In this talk, I will present a disproof of the “third law of black hole thermodynamics” by showing that extremal black holes can form in the gravitational collapse of charged matter. This has opened the door to studying a new critical phenomenon on the black hole formation threshold that we call “extremal critical collapse.” This is joint work with Christoph Kehle (ETH Zürich).
