Reply to comment by B4SSF4C3 in Ultramassive black hole over 30 billion times mass of our sun has been spotted. The discovery had been made possible thanks to a phenomenon known as gravitational lensing — the first time a black hole has been spotted in such a way. by Wagamaga

A 30 billion solar mass black hole has a diameter of nearly 600 times that of earths orbit around the sun. That's pretty big.

You are referencing event horizon, not the singularity. But I suppose I’ll agree that if considering the overall black hole phenomena, the event horizon would be a more logical “edge” to reference.

Yes. That is what is generally understood as the size of a black hole.

I see you're studying for your degree in pedantry. A black hole is it's event horizon and everything inside it.
