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).
[math]\displaystyle{ (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 }[/math]
ds is the path it follows
dt is the change in time
dr is the change in radius
d[math]\displaystyle{ \theta }[/math] and d[math]\displaystyle{ \phi }[/math] are the change in angle
[math]\displaystyle{ \theta }[/math] is also the angle
[math]\displaystyle{ r_s }[/math] 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.[2]
