## Schwarzschild black hole
There are three important features of a Schwarzschild black hole: - A photon sphere 1.5 times bigger than the Schwarzschild radius
- An event horizon: effectively, the outer surface of the black hole; its distance from the singularity is the Schwarzschild radius
- A point singularity where space and time have infinite curvature
