Theoretically, dark matter could create black holes. But that thing requires that the dark matter exists in the form of particles. And another thing that the form of black holes from dark matter requires is that dark matter exists. Confirmation that some black hole is formed from the dark matter requires that the black hole is not formed in the collision of neutron stars. So there must not be a neutron star collision at the point, where the black hole is formed. Or there are no supernova remnants around it. So that kind of black hole should form from emptiness. And a black hole can pull all supernova remnants inside it. There is also the possibility. That a supermassive black hole forms straight from the interplanetary nebula. In that case, that very massive nebula collapses because there is forming a gravitational center, and then it can form a black hole. In the same way, a black hole that forms from a neutron star collision should leave some kind of remnant of that event. But th
