I follow the latest developments in astrophysics, and Hawking lectured on black holes just a few weeks ago on R4.

I do not know where Donuel finds this stuff or if he makes it up himself, but it does not come from the scientists working in the field.
See if you can find it Musket.

"According to our present understanding.." Donuel's physics is tosh.


a rebounding black hole star.

No such thing. When a stellar core collapses, the outer shells fall on to it and rebound but it is the core that becomes a white dwarf, neutron star or black hole depending on the mass.

The explosion of a black hole he describes in detail has never been observed.
