Here's a quote by Modred from another thread: https://www.physicsforums.com/showthread.php?t=683377 My question isn't about the Hawking radiation part of the statement, its about the "uncharged non-rotating blackhole" part. how do we know if a black hole is charged, what it's charge is, and if it is rotating and how much. I thought a black hole was a singularity. How can a singularity have charge and rotate or not rotate? If you have gotten this far with an explanation, then please tell me the factors or variables that lead a black to be charged or not, or to spin or not.
