Schwarzschild Radius

Visualize any celestial body, say the Earth. Now some great marvel supervillain picks up the earth and starts compressing it. The radius of the compressed earth which is of that distance that converts our planet into a black hole is called a Schwarzschild radius, or the gravitational radius. Simply put, it is the radius at which any body will turn into a black hole. 

How does that work? Well, if you've read the earlier posts, you know that black holes are points of too much mass in a very small space, which means they are very dense. When any object is made that dense, it will turn into a black hole. In other words, if all of the earth's mass was contained in one inch, that would become a black hole. 

It was given by Karl Schwarzchild, and you can calculate it for absolutely anything. For example, if I wanted to become a black hole, I would have to become around ten times smaller than an electron.

That's it about Schwarzschild radius, thank you for reading.
