It’s probably some obvious volumetric thing, like how the volume of a sphere increases exponentially when you increase the radius. V = 4/3 πr³. It seems the mass is some radius analogue in whatever equation governs black holes.
It’s also interesting to note that the surface area of a black hole’s event horizon is proportional to how much inormation the black hole contains. This was discussed in a recent PBS Spacetime Video.
The thing is, you have to first create the black hole with the mass of the universe in order to be so large that it has the same average density as air, right? Maybe I’m totally wrong and need to watch the video.
Because math. Also, it’s the average density.
