The Maldacena Conjecture, or AdS/CFT correspondence, posits a duality between a type of string theory formulated on Anti-de Sitter space and a conformal field theory defined on its boundary, suggesting that gravitational theories in higher-dimensional spaces can be equivalent to non-gravitational theories in lower dimensions. This groundbreaking idea provides a powerful tool for studying quantum gravity and has profound implications for understanding black holes and the nature of spacetime itself.
