The anti-de Sitter/conformal field theory (AdS/CFT) correspondence, also referred to as gauge/gravity duality, hypothesizes the existence of a relationship between two types of physics theories, namely gravity theories in ...
(Phys.org) —Frans Pretorius and William East of Princeton University have published a paper in Physical Review Letters, where they describe computer models they've developed that show that it would require 2.4 times less ...
Our ideas about the universe are based on a century-old simplification known as the cosmological principle. It suggests that when averaged on large scales, the Cosmos is homogeneous and matter is distributed evenly throughout.
