Missing: Milky Way’s smallest black holes
Larger stars are thought to explode with less energy than smaller ones, Fryer says. That means lower-mass stars that go on to form neutron stars would blast more of their outer layers away than higher-mass stars that become black holes. The extra material the higher-mass stars hold onto could then fall into the black holes, bulking them up. This could explain the dearth of the puniest black holes, he says.
It’s obvious why there aren’t many small holes. For the most part, people are busy digging even deeper holes for themselves, or else they’ve climbed out and are filling in the hole they started.
Here are people digging even deeper holes.
