In summary, in December 2013, it was reported that Yoshifumi Hyakutake had proposed a justification for the holographic description of the universe based on the gauge/gravity duality. Since then, there has been progress in testing this theory on a computer, with a recent paper by Masanori Hanada, Yoshifumi Hyakutake, Goro Ishiki, and Jun Nishimura providing further evidence for the validity of this concept. This approach has the potential to advance our understanding of quantum gravity and potentially solve the information loss paradox in black holes. However, it does not necessarily mean that our own universe is a hologram, as it is based on asymptotically AdS universes. The

Holographic description of quantum black hole on a computer
Masanori Hanada, Yoshifumi Hyakutake, Goro Ishiki, Jun Nishimura
(Submitted on 21 Nov 2013)
The discovery of the fact that black holes radiate particles and eventually evaporate led Hawking to pose the well-known information loss paradox. This paradox caused a long and serious debate since it claims that the fundamental laws of quantum mechanics may be violated. A possible cure appeared recently from superstring theory, a consistent theory of quantum gravity: if the holographic description of a quantum black hole based on the gauge/gravity duality is correct, the information is not lost and quantum mechanics remains valid. Here we test this gauge/gravity duality on a computer at the level of quantum gravity for the first time. The black hole mass obtained by Monte Carlo simulation of the dual gauge theory reproduces precisely the quantum gravity effects in an evaporating black hole. This result opens up totally new perspectives towards quantum gravity since one can simulate quantum black holes through dual gauge theories.

Just a few comments. It doesn't show that our universe is a hologram. Rather, Maldacena proposed that quantum field theories without gravity in D dimensions are theories of gravity in D+1 dimensions. The universes described by such theories probably do not include ours, because they are universes that are asymptotically AdS. Nonetheless, it is hoped that if the conjecture is right, then understanding it will help us constuct other theories of quantum gravity. There's been lots of evidence to support Maldacena conjecture over the years, and this paper by Hanada et al provides more support, in the form of numerical simulations.

1. What is the Yoshifumi Hyakutake theory?

The Yoshifumi Hyakutake theory is a scientific explanation proposed by Japanese astronomer Yoshifumi Hyakutake in 1994. It hypothesized that comets originate from a hypothetical Oort cloud, a region in the outermost parts of the solar system, and follow a long, elliptical orbit around the sun.

2. Has the Yoshifumi Hyakutake theory been proven?

The Yoshifumi Hyakutake theory is still considered a theory and has not been proven. However, it has been widely accepted by the scientific community and is supported by various observations and studies.

3. What happened to the Yoshifumi Hyakutake theory?

The Yoshifumi Hyakutake theory is still a valid scientific explanation, but it has been refined and expanded upon by other theories, such as the more widely accepted "nice model" proposed by scientists Hal Levison and Luke Dones in 2008.

4. Why is the Yoshifumi Hyakutake theory important?

The Yoshifumi Hyakutake theory was one of the first proposed explanations for the origin and behavior of comets, which are important celestial bodies that provide insights into the formation and evolution of the solar system.

5. Is the Yoshifumi Hyakutake theory still relevant today?

Although it has been refined and expanded upon, the Yoshifumi Hyakutake theory is still relevant and plays a role in current research and understanding of comets and the outer solar system.
