Cardy’s Conjecture

Cardy’s Conjecture is a theoretical idea in physics suggesting that the behavior of certain systems—specifically, two-dimensional conformal field theories—can be predicted precisely by a mathematical formula. It states that the number of ways the system can be arranged (its entropy) at high energy levels depends mainly on fundamental properties called the central charge and the energy level itself. This conjecture helps physicists understand the relationship between microscopic details and large-scale behavior, especially in areas like quantum field theory and string theory. It has been supported by various mathematical proofs and is a key insight into the structure of these theories.
