OK, black holes fascinate me as well. I get the associated physics and the rather simple math, but it’s interesting that nobody including the physics community have really not got on top of the concept of a physical singularity, a body with no dimensions and gigantic mass. They are not really sure if the singularity really exists. This is because of the issue of quantum gravity, ie what happens to gravity at quantum distances. Anyway, my special curiosity is that most black holes supposed to rotate. Now, how does a body with no diameter, a point in space rotate. If it has no dimensions, a perfect point source, it will look exactly the same from any direction, how can it rotate. This rotation is the supposed source of extremely twisted magnetic field lines emanating from the single point location of the hole which also supposed to drive the high speed luminous material jets 100s of light years into space.
Anyone has a problem with the concept of black hole rotation?
