Possibility of holographic universe confirmed in computer models

Nature : In 1997 Juan Maldacena proposed a theory in which gravity could arise via string theory in a 10-dimensional universe, provided the universe was actually a holographic projection of a lower-dimensional universe that had no gravity. The theory was very well received because it appeared to provide a strong connection between string theory and reality and between quantum physics and general relativity. Two new papers by Yoshifumi Hyakutake of Ibaraki University in Japan and his colleagues have provided the first confirmation of a possible connection between a lower-dimensional universe and a higher-dimensional projection. They created a model of a 10-dimensional universe and calculated several properties of a black hole, including its internal energy. They then modeled the 1-dimensional universe that could create the 10-dimensional universe as a projection and again calculated the internal energy of the black hole. The two models resulted in equivalent values, the first numerical confirmation of Maldacena’s theory.
