Uh-oh: Black hole up to 100 billion times the mass of the sun has vanished

I wonder if black holes can collapse further into a point in space time ?

They say, this is only anecdotal speculation, they say that if you were looking at it when it vanished that you’d vanish too and people have vanished, people like Boris.
Spooky.

It doesn’t work that way. There is a little thing called “conservation of mass” or, if you want to be pedantic, “conservation of mass-energy”.

I think what they mean here is that an X-ray source has vanished. X-ray sources can be black holes or pulsars. A cessation of infalling matter would cause a black hole X-ray source to vanish. Perhaps the previous X-ray source was when something (gas or solid) was sucked in. Now that it’s no longer being sucked in, it’s no longer emitting X-rays.
