aug 22, 1915 - German physicist Karl Schwarzschild
Description:
provides the first exact solution to Einstein’s field equations of general relativity (even before Einstein publishes the theory) for the limited case of a single spherical non-rotating mass, which leads to the “Schwarzschild radius” which defines the size of the event horizon of a non-rotating black hole.Added to timeline:
