What is the Schwarzschild radius of a human being?
The Schwarzschild radius of the Earth is just 9mm.
Do people have enough mass to compress into a black hole? Just curious.

lets assume the human has a mass of 55 kg.
Schwarzchild radius = 2GM/c^2
G is newtons constant, 6.67428 x 10^-11
M is the mass of the object, the human, 55 kg
c is the speed of light, 299,792,458 m/s
Schwarzchild Radius = 2 x 6.67428 x 10^-11 x 55/299,792,458^2
Schwarzchild Radius = 8.16875 x 10^-26 meters = 8.16875 × 10^-17 nanometers
1 nanometer is a billionth of a meter and a millionth of a millimeters.
Extremely small, much smaller than any atom.

It's 1.48e-27 m/kg, so a 100 kg person would have a Schwarzschild radius of only 1.48 x 10^-25 m. Since a neutron is about 10^-15 m, that's pretty small.
A black hole that small is supposed to be unstable, evaporating instantly from Hawking radiation. I think that the form of the evaporation is a shower of particles of matter and antimatter, though I'm no expert.

Technically everything has enough mass to become a black hole if you compress it enough. But for most things on our scale you would need some kind of hand wavy magic to do the compressing. You really want a mass at least five times that of our sun(I think, fact check me. I may be off a solar mass or two in one direction or the other) for something to naturally collapse into a black hole.
