The holographic universe, an idea first suggested in the 1990s, is one where all the information that makes up our 3D "reality" (plus time) is contained on a 2D surface. The idea is similar to that of an ordinary hologram on a credit card, where a three dimensional image is encoded on the two dimensional card. A team of UK, Canadian, and Italian theoretical physicists have now provided what is believed to be the first observational evidence that our universe could indeed be a vast and complex hologram. They have found substantial evidence supporting a holographic explanation of the universe -- In fact, as much evidence as currently exists for traditional explanations based on the widely accepted theory of cosmic inflation.
