Black hole density 40x proton

I calculated the density of a black hole from the Schwarzschild radius (r) of the Sun and the Sun's mass. r is 2950 meters. The black hole density is d. A proton radius (R) is .95fm

d = Mass / Volume = 2*10^30 kg / (4/3 pi r^3) = 1.85*10^19 kg / cubic meter

proton density = 1.6738*10^-27kg /(4/3 pi R^3) = 4.66*10^17 kg / cubic meter

The ratio of those densities is 40. That is true for larger black holes, too. I am speculating on the meaning of that 40 ratio. Maybe it is because of one of these ideas:

1 Length contraction lets more baryons fit into the outer part of a black hole, while protons are spherical near the center.

2 Protons are changed into a soup of baryonic viscera so they get compacted because no measureable surfaces remain of what we had measured in colliders.

Why is a black hole 40 times as dense as a proton?

How large is a meter inside a black hole?

The average meter is 1/2950 of the radius of a BH with mass like the Sun.

As seen from which corner?

You asked two question. I answered one. Your turn at my two questions.

m/V = m/(4/3 pi a^3)

a = 2m, thus V = 32pi/3 m^3;

therefore:
ro = m/V = 3/32pi 1/m^2

so, the black hole density is not 40 times as proton,
because this density depends on the mass:

the more mass the less density.

You know, I have a little script that looks for certain words and then
asks me if the poster should go into a kill file. It's very effective.

Only complete idiots come on usenet with killfils. Your choice, feel free.

Only idiots spend a fair amount of time generating another nym, when
killfiling that nym takes one click. It's pissing upwind. Good luck with
that.

He probably signed up with some anonymous service which generates random
names automatically for him. It seems to be Aruba S.p.A from Italy:
https://www.aruba.it/en/home.aspx
Never used them so I have no comment otherwise.
