Black hole

Stephen Hawking's groundbreaking work in 1974 introduced the concept of Hawking radiation, which posits that black holes emit energy and gradually lose mass over time. This phenomenon arises from quantum effects near the event horizon of a black hole.

The prediction of Hawking radiation was a significant departure from the classical understanding of black holes, which were thought to be completely black and devoid of any radiation. Hawking's theory incorporated elements of quantum mechanics and general relativity, providing a new perspective on black hole thermodynamics.

Hawking radiation implies that black holes are not entirely black but instead emit particles, leading to a slow evaporation process. This concept has profound implications for our understanding of black holes, suggesting they are not eternal but have a finite lifespan.
