New papers from the Ibaraki University in Japan provides evidence backing years of theoretical physics research regarding string theory and the holographic principle, both of which are seriously-discussed scientific descriptions of the universe. The latter, which suggests that any three-dimensional volume of space can be encoded on the boundary a two-dimensional volume of space, is widely accepted. A less widely-accepted but still discussed theory applies the holographic principle to the entire universe, claiming that Earth and the rest of the stars, planets and cosmic material are actually a projection of another two-dimensional space that exists on the edge of the universe. This, in turn, can be described as a “hologram.”

Of course, the concept of a hologram only exists because humans living in this universe used scientific knowledge and practice in order to create the holographic method, a process which occurred relatively recently (in the early 20th century). Thus, the description that the universe could be a “hologram” is simply the term used by researchers to describe it to individuals so that it makes sense in the context of things that exist on earth right now.

One of Hyakutake’s research papers “computes the internal energy of a black hole, the position of its event horizon (the boundary between the black hole and the rest of the Universe), its entropy and other properties based on the predictions of string theory as well as the effects of so-called virtual particles that continuously pop into and out of existence,” according to the Huffington Post. Another paper demonstrates the calculation of “a lower-dimensional cosmos with no gravity,” which matches with the other computer’s calculation. This mathematical evidence would explain that the interaction between the two universes of these types could essentially be proven.

Juan Maldacena, a theoretical physicist at the Institute for Advanced Study in Princeton who proposed a similar theory in 1997, claimed that Hyakutake’s calculations appeared to make sense.

“It seems to be a correct computation,” Maldacena said.

Theoretical physics made headlines in 2012 with the discovery of the Higgs Boson, which proved the particle theory initially conceived in 1964. Hyakutake and his team’s calculations, while not quite as revolutionary in scale as the Higgs-Boson, also demonstrate mathematical proof of a concept long accepted by the scientific community.

Because the evidence is still purely mathematical, however, it cannot fully be accepted as evidence. As recently as 2011, i09 reported on a similar attempt to prove the holographic principle that failed. Also, even with proof that the holographic principle exists, it would still take much more research and effort to decipher whether or not the entire universe is a so-called hologram. Like many theories about the nature of the universe, however, it hasn't yet been disproven, so it's still worthy of consideration in that aspect.
