black hole entropy
Black hole entropy is a measure of the amount of information about the microstates of a black hole's matter and energy. According to physicist Jacob Bekenstein and others, a black hole's entropy is proportional to the area of its event horizon, not its volume. This idea suggests that even black holes, with their intense gravity and complexity, adhere to the laws of thermodynamics. Essentially, black holes can be understood as entities that store information, and their entropy reflects the hidden details of the universe, bridging concepts from quantum mechanics and general relativity.

Black hole entropy refers to the measure of disorder or unpredictability associated with a black hole, analogous to the concept of entropy in thermodynamics. In simple terms, it quantifies the amount of information that is hidden within a black hole. According to the laws of physics, particularly the second law of thermodynamics, a black hole's entropy increases with its surface area, not its volume. This relationship suggests that the information about everything that falls into a black hole is encoded on its event horizon, leading to profound implications for our understanding of gravity, information, and the universe.
