# "Our Holographic Universe" --Will It Show to Be the Greatest Theory of the 21st Century

Whether we actually live in a hologram is person hotly debated, but it is now becoming clear that look at phenomena through a holographic lens could be key to solving some of the majority perplexing problems in physics. Previous month, Japanese physicists obtainable in Nature News as "the clearest proof yet that our Universe could be just one large projection." The universe obtainable as a ‘hologram’ is the theory that the 3 dimensions we perceive are in fact just “painted” onto the cosmological horizon - the boundary of the recognized universe.

In 2 papers on arXiv, that represent the the culmination of a lot of years’ work focused on hypothetical calculation of the energies of black holes in different universes, Yoshifumi Hyakutake & colleagues from Ibaraki University in Japan present evidence that supports a theory that suggests that a universe as we conceive of it could in fact be a hologram of another two-dimensional space --a holographic projection of another, flat version of you income on a two-dimensional "surface" at the edge of this universe. This radical model of the universe helps explain a number of inconsistencies between general relativity (Einstein’s theory) & quantum physics. At certain extremes (such as in the center of a black hole) Einstein's theory break down & the laws of quantum physics take over.

The standard method of integration these two models has come from the 1997 work of theoretical physicist Juan Maldacena, at the Institute for Advanced Studies in Princeton, who proposed a radical model of the Universe in which gravity arises from infinitesimally thin, vibrating string which exist in nine dimensions of space plus one of time, and would be a hologram --a simpler, compliment cosmos where there is no gravity. Maldacena's theory provide physicists with a mathematical Rosetta stone, a 'duality', that allowable them solve problems in one model that seemed impenetrable in the other, but has yet to receive a rigorous proof. A theory that Columbia University mathematican PeterWoit describe as "not even wrong."

In one paper2 described in Nature, Hyakutake compute the internal energy of a black hole, the position of its event horizon (the border between the black hole and the rest of the Universe), its entropy and other properties base on the predictions of string theory as well as the effects of so-called virtual particles that incessantly pop into and out of existence. Paper 3, calculates the internal energy of the corresponding lower-dimensional cosmos with no gravity. The two computer calculation match.

Maldacena embraced the latest research as “an interesting way to test many ideas in quantum gravity and string theory.” “The whole sequence of papers is very good because it tests the dual [nature of the universes] in regimes where there are no analytic tests," he extra.

”Leonard Susskind, a theoretical physicist at Stanford-University who was among the first theoreticians to explore the design of holographic universes and was one of the founders of string theory, added that the work by the Japanese team “numerically confirmed, perhaps for the first time, something we were fairly certain had to be true, but was still a conjecture.”

Maldacena finished that "the numerical proof that these two seemingly disparate worlds are in fact identical gives expect that the gravitational properties of our Universe can one day be explain by a simpler cosmos only in terms of quantum theory."
