Stephen Hawking Radiation

Stephen Hawking radiation is a theoretical process where black holes emit particles and gradually lose mass over time. Near the event horizon, quantum effects cause pairs of particles to appear spontaneously; sometimes one falls into the black hole while the other escapes, appearing as radiation. This means black holes are not completely black; they slowly evaporate, emitting a faint glow. Hawking radiation combines principles of quantum mechanics and gravity, suggesting black holes have a finite lifespan. It revolutionized our understanding of black holes and their thermodynamic properties, blending ideas from different physics fields into a cohesive theory.
