Prof. Christoph Kehle and his colleagues have demonstrated “that there is nothing in our known laws of physics to prevent the formation of an extremal black hole,” reports Steve Nadis for Quanta Magazine. The mathematical proof is “beautiful, technically innovative and physically surprising,” says Princeton University Professor Mihalis Dafermos. It hints at a potentially richer and more varied universe in which “extremal black holes could be out there astrophysically.”
