black hole evaporation

Black hole evaporation, known as Hawking radiation, occurs when quantum effects near the black hole's event horizon produce particle-antiparticle pairs. Sometimes, one particle falls into the black hole while the other escapes as radiation. As this process continues, the black hole loses mass and energy, gradually shrinking over time. Essentially, black holes can slowly evaporate, emitting detectable radiation, until they eventually disappear. This phenomenon bridges quantum mechanics and gravity, revealing that black holes are not entirely "black" and can have a finite lifespan.
