A team of physicists have claimed to have found some of the clearest evidence yet that our Universe could be a hologram.
In 1997, theoretical physicist Juan Maldacena said that a model of the Universe in which gravity arises from infinitesimally thin, vibrating strings may be reinterpreted in terms of well-established physics, the Huffington Post reported.
Yoshifumi Hyakutake of Ibaraki University in Japan and his colleagues have now provided compelling evidence that Maldacena’s conjecture is true.
In one paper, Hyakutake computes the black holes internal energy, the position of its event horizon, its entropy and other properties that are 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.
In the other, he and his team calculated the internal energy of the corresponding lower-dimensional cosmos with no gravity and when they compared the two computer calculations they found that they matched.
Leonard Susskind, a theoretical physicist at Stanford University in California who was among the first theoreticians to explore the idea of holographic universes, said that the team has numerically confirmed something that they were fairly sure had to be true, but was still a conjecture - that the thermodynamics of certain black holes could be reproduced from a lower-dimensional universe.
The two papers have been posted on the arXiv repository.
