The holographic principle states that the entropy of ordinary mass (not just black holes) is also proportional to surface area and not volume; that volume itself is illusory and the universe is really a hologram which is isomorphic to the information "inscribed" on the surface of its boundary.
In a holographic reconstruction, each region of a photographic plate contains the whole image. Bohm employed the hologram as a means of characterising implicate order, noting that each region of a photographic plate in which a hologram is observable contains within it the whole three-dimensional image, which can be viewed from a range of ...
The theory that the universe is a holographic entity was first introduced in the 1990s. This differs from the theory that the earth is a simulation, however.
Holonomic brain theory is a branch of neuroscience investigating the idea that consciousness is formed by quantum effects in or between brain cells. Holonomic refers to representations in a Hilbert phase space defined by both spectral and space-time coordinates. [1]
This theory could explain the mysterious disappearance of information about matter and energy inside a black hole, but it the concept has its flaws. The Universe May Be a Hologram, Meaning Our ...
Here the theory in the bulk is a type of gauge theory describing particles of arbitrarily high spin. It is similar to string theory, where the excited modes of vibrating strings correspond to particles with higher spin, and it may help to better understand the string theoretic versions of AdS/CFT and possibly even prove the correspondence.

To preserve the holographic principle, Bousso proposed a different law, which does not follow from black hole physics: the covariant entropy bound [3] or Bousso bound. [ 4 ] [ 5 ] Its central geometric object is a lightsheet , defined as a region traced out by non-expanding light-rays emitted orthogonally from an arbitrary surface B.
The first theory, now believed to be the correct one, is that the universe started for some unknown reason in a low-entropy state. The second and alternative theory, published in 1896 but attributed in 1895 to Boltzmann's assistant Ignaz Schütz , is the "Boltzmann universe" scenario.
