Question

Quizplus · Accepted Answer

According to the theory of relativity, the Schwarzschild radius is the point of no return for anything, including photons, neutrinos, or even antiparticles. Within this radius, the gravitational pull of a black hole becomes so strong that it is impossible for anything to escape, not even light. Hence, nothing can escape from within the Schwarzschild radius of a black hole.
