Swirling Dust Near Black Hole Too Thick for Theory

Time to change thories about the black hole. I guess not all are alike. I don't know much on the subject but found it interesting. Here it is:

A close-up view of a donut-shaped disk of dust around a black hole confirms several expectations about the massive structure but has astronomers wondering how the disk could be so thick.

The black hole packs a mass equal to about 10 million Suns. That's more than twice the mass of the black hole in our Milky Way but many times less than others in the more distant universe. It anchors a nearby galaxy called NGC 1068.

not all black holes are alike. there are a few different types of black holes known.

1. Supermassive: which are at the center of galaxies
   
2. Primordial: black holes that formed during the creation of the universe. they can range in size, but most are nanometers or smaller in size
   
3. Scharzchild: black holes that do not rotate
   
4. Kerr: rotating black holes, with an ergoregion (an intense magnetic field, which allows for some particles to contain orbits)
