Oppenheimer–Snyder solution

The Oppenheimer-Snyder solution describes the behavior of a collapsing star under the rules of general relativity. It explains how a massive, dying star can contract due to gravity, leading to the formation of a black hole. As the star collapses, the intense gravity distorts space and time around it, creating an event horizon—the point of no return beyond which nothing can escape, not even light. This solution helps us understand the final stages of stellar evolution and the nature of black holes, illustrating the complex interplay between mass, gravity, and the fabric of the universe.
