Black Hole Evaporation: Hawking Radiation Explained
- In 1974, Stephen Hawking proposed that black holes can slowly lose mass and energy.
- This process, called Hawking radiation, arises from quantum effects near the event horizon.
- Virtual particle pairs constantly pop in and out of existence in empty space.
- Near a black hole, one particle may fall in while the other escapes, appearing as radiation.
- To conserve energy, the black hole loses a tiny bit of its mass with each emission.
- Over unimaginable timescales, this leads to black hole evaporation.
- Small black holes would evaporate faster than supermassive ones.
- In the final stages, an evaporating black hole could release a powerful burst of energy.
- Hawking radiation unites quantum mechanics, relativity, and thermodynamics in one framework.
- Although never directly observed, it is one of the most influential ideas in modern physics.
