Entropy in Black Holes

Entropy in black holes measures the amount of hidden information or disorder within them. It relates to the number of ways a black hole's internal states can be arranged while appearing the same externally. The more entropy a black hole has, the greater its internal complexity. Interestingly, black hole entropy is proportional to the area of its event horizon (the boundary beyond which nothing escapes), not its volume. This insight connects gravity, quantum theory, and thermodynamics, suggesting that black holes are deeply linked to fundamental information principles in physics.
