Question How can one singularity be bigger than another?

I was under the impression that a singularity is an absolute. Once sufficient mass is concentrated in a sufficiently confined volume, regardless of the variations of the ratio, it collapses into a singularity. This sounds like a greater or lesser zero. Zero is zero, is it not?

It is not a Zero. a singularity is where the math breaks down and is undefined. What they are referencing is the measument of size of the event horizon, which is the size of the orbit of light around the black hole. Closer than that radius, the light will spiral "in" to the singularity as it does not go fast enough to maintain the orbit. Farther out and the speed of light will allow it to spiral out and escape. The more massive the black hole the larger that orbit becomes. The Mass/gravity/event horizon are all positively related.

Thank you. I have been thinking of black holes incorrectly. This also explains the phrase "micro-black hole" that I have heard.
