Karl Schwarzschild (9 October 1873 – 11 May 1916) was a German physicist and astronomer.

Best known for his solution to Einstein's equations of general relativity, which describes a the gravitational field outside a non-rotating black hole with no magnetic field.

The equation describes how a particle moves space near this black hole (using spherical coordinates).
(ds)^2=-c^2(1-\frac{r_s}{r})(dt)^2+\frac{1}{(1-\frac{r_s}{r})}(dr)^2+r^2(d\theta)^2+r^2\sin^2(\theta)(d\phi)^2

ds is the path it follows
dt is the change in time
dr is the change in radius
d\theta and d\phi are the change in angle
\theta is also the angle
r_s is the set radius limit of the heavy object
r is how close the travelling object is to the heavy object
c is the speed of light

This equation is also known as the Schwarzschild metric or Schwarzschild solution.
