Penrose's Theorem

Penrose's Theorem, in the context of general relativity, states that under certain realistic conditions—such as the presence of massive objects and energy—spacetime inevitably contains a singularity, a point where gravity becomes infinitely strong and the laws of physics break down. This theorem suggests that singularities, like those at the centers of black holes, are a natural outcome of gravitational collapse and not just theoretical curiosities. Essentially, it mathematically proves that singularities are an unavoidable feature of the universe's structure under specific conditions.
