Karl Schwarzschild

Definition

Karl Schwarzschild was a German physicist and astronomer known for his significant contributions to the field of general relativity, particularly for deriving the Schwarzschild solution. This solution describes the gravitational field outside a spherical, non-rotating mass, leading to important implications such as the understanding of black holes and the geometry of spacetime in their vicinity.

1. The Schwarzschild solution was the first exact solution to the Einstein field equations in general relativity, published in 1916.
2. Schwarzschild's work provided the first theoretical basis for understanding black holes, showing that a collapsed star could create a singularity surrounded by an event horizon.
3. The Schwarzschild metric describes how spacetime is curved around a spherical mass, affecting the motion of objects and light nearby.
4. Schwarzschild’s findings were crucial during the early 20th century when astronomers began to gather evidence for the existence of black holes.
5. The formula for the Schwarzschild radius is given by $$r_s = \frac{2GM}{c^2}$$, where G is the gravitational constant, M is the mass of the object, and c is the speed of light.
