The fact that this is not what we observe suggests that there's something hinky going on: a huge gap in our understanding ... That explanation agrees with theories such as black hole cosmology, which ...

Simulations of highly magnetized stars that explode and collapse into black holes show that they transfer their magnetic fields to the disk of swirling matter that forms around the new black hole.
