Guest_Jim_* Posted April 28, 2015 Posted April 28, 2015 Holography is an interesting field of science with how it can create three-dimensional views with two-dimensional systems. This is something you can see in credit cards and even some banknotes, and back in 1997 it was suggested that the principles of holography could be applied to the Universe itself. Now researchers at the Vienna University of Technology have discovered an unexpected level of correspondence between two theories that apply to the Universe. Holograms create images with so many dimensions by combining two systems of lower dimension. If applied to the Universe that would mean it can be described mathematically with one fewer dimension than we think. We already know that the holographic principle can be applied to some spaces by a correspondence between gravitational theories, which have three dimensions, and quantum field theories, which were calculated in just two dimensions, but those spaces would have to be curved in a negative direction, while the Universe has flat curvature, or positive over great distances. The Vienna researchers however have found that the correspondence actually does still exist in a flat space. To do this they had to find properties of one theory in the other, such as quantum entanglement in gravitational theory. While this work does indicate that the correspondence principle does likely apply to our Universe, it does not immediately mean the Universe is actually a hologram.
