How big is your average black hole?
We speak of them being infinitely dense, but I take that to be a metaphor for something so incredibly dense that is beyond common understanding of the property, density. We speak of them being infinitely small, but that seems inconsistent with the visible event horizon and the size they exhibit when wandering ones create gravitational lensing of light from stars beyond themselves. So how many Earth diameters might a super-massive black hole be?
