Schwarzschild metric

Schwarzschild radius at r=2GM/c² marks the event horizon

The Schwarzschild radius is the same for all black holes, regardless of their mass. This uniformity is due to the fact that the Schwarzschild metric is the most general spherically symmetric vacuum solution of the Einstein field equations. The event horizon at this radius is a defining characteristic of Schwarzschild black holes.

Understanding the Schwarzschild radius is essential for studying black holes and their properties in the context of general relativity. It helps us comprehend the fundamental nature of these cosmic phenomena and their impact on the surrounding space-time.
