Karl Schwarzschild

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 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 is the path it follows 
dt is the change in time 
dr is the change in radius 
d and d are the change in angle 
 is also the angle 
 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.Czerniawski, Jan. , The possibility of a simple derivation of the Schwarzschild metric. Retrieved on 10 May, 2020.
