UnverifiedMaldacena's 1997 paper gave the first precisely calculable example: supergravity in five-dimensional AdS space is mathematically equivalent to a supersymmetric quantum field theory on its four-dimensional boundary.68% similarUnverifiedA conformal field theory (CFT) is a class of quantum field theories that preserve symmetry under arbitrary scale transformations, contain no gravity, and live on a boundary one dimension fewer than the bulk space.66% similarUnverifiedHow to extend the holographic principle to the real acceleratedly expanding universe remains a core unsolved problem, and the construction of dS/CFT duality is one of the most active and most challenging frontier problems in the field of quantum gravity.64% similarUnverifiedIn 1915, Einstein published the general theory of relativity, redefining gravity as the curvature of spacetime.62% similarUnverifiedThe negative result of the Michelson-Morley experiment paved the way for the theory of relativity.60% similar
