SMBH Spin Rate
In the Face Book group:
Post had image with SMBH spin rate at 270,000,000 m/s
This is silly. A black hole singularity has zero radius so its circumference is zero. There is no surface to move.
Any number specified for a black hole spin is fantasy.
I got this response:
I don’t think they were speaking directly about the singularity. Black holes do spin.
My response to his comment and its link:
The claim is very misleading.
A black hole cannot emit anything; it is black.
The X-rays must be coming from something else, not the black hole.
The X -ray emission is coming from synchrotron radiation - so there are electric currents interacting with a magnetic field - and this is NOT a black hole. If the X-ray intensity changes with a measurable period that is electrical in nature, not some 'incredible speed.'.
