In existential news, Tupac isn’t the only one who may merely be a flat holographic projection. Via Nature:
A team of physicists has provided some of the clearest evidence yet that our Universe could be just one big projection.
In 1997, theoretical physicist Juan Maldacena proposed an audacious model of the Universe in which gravity arises from infinitesimally thin, vibrating strings. The mathematically intricate world of strings, which exist in nine dimensions of space plus one of time, would be merely a hologram: the real action would play out in a simpler, flatter, single dimensional cosmos where there is no gravity.
Maldacena’s idea thrilled physicists because it solved apparent inconsistencies between quantum physics and Einstein’s theory of gravity.
In two papers posted on the arXiv repository, Yoshifumi Hyakutake of Ibaraki University in Japan and his colleagues now provide, if not an actual proof, at least compelling evidence that Maldacena’s conjecture is true.
