Anti-de Sitter/Conformal Field Theory (AdS/CFT) Correspondence

The Anti-de Sitter/Conformal Field Theory (AdS/CFT) correspondence is a theoretical idea suggesting a deep connection between gravity in a warped, higher-dimensional space (AdS space) and a quantum field theory without gravity on its boundary. Essentially, it links a universe with gravity to a lower-dimensional universe without gravity, allowing scientists to study complex problems in one using the other. This duality has provided insights into quantum gravity, black holes, and strongly interacting particles, serving as a powerful mathematical tool bridging gravity and quantum physics.
