Hawking's theory demonstrates that black holes emit virtual particles, leading to their evaporation and energy dissipation. This process raises questions about entropy, as a shrinking black hole appears to decrease entropy, potentially violating the second law of thermodynamics. However, the analogy of freezing water illustrates that local decreases in entropy do not contravene the second law when considering the entire system. Thus, black hole evaporation does not violate thermodynamic principles when viewed in a broader context.
PREREQUISITESPhysicists, cosmologists, and students of theoretical physics interested in the intersection of black hole mechanics and thermodynamic laws.
Einstein's Cat said:Hawkings showed that black holes dissipate energy when virtual particles are "emitted" by black holes and therefore black holes evaporate.
Einstein's Cat said:However it seems to me that a shrinking black hole means a decrease in entropy
Einstein's Cat said:nd thus a violation of the second law of thermodynamics
