The holographic principle is a property of string theories and a supposed property of quantum gravity that states that the description of a volume of space can be thought of as encoded on a lower-dimensional boundary to the region – such as a light-like boundary like a gravitational horizon.
In principle, it is possible to make a hologram for any type of wave. A hologram is a recording of an interference pattern that can reproduce a 3D light field using diffraction. In general usage, a hologram is a recording of any type of wavefront in the form of an interference pattern.
A holographic image can also be obtained using a different laser beam configuration to the original recording object beam, but the reconstructed image will not match the original exactly. [2]: Section 2.3 When a laser is used to reconstruct the hologram, the image is speckled just as the original image will have been.
This theory could explain the mysterious disappearance of information about matter and energy inside a black hole, but it the concept has its flaws.
Mark Germine argues that the evolution of consciousness is linked to the holographic principle of mind through a recursive process of successive applications of the same holographic process. According to Germine, the most fundamental levels of experiences— from the conformations of proteins and fields of electrons— exist as quantum potentials.
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 holographic principle states that gravitational theories in a given dimension are dual to a gauge theory in one lower dimension. The AdS/CFT correspondence is one example of such duality. Here, the field theory is defined on a fixed background and is equivalent to a quantum gravitational theory whose different states each correspond to a ...
Holographic theory may refer to: The holographic principle - a concept in physics whereby a space is considered as a hologram of n-1 dimensions. The holographic paradigm - a concept in quantum mysticism, wherein the holographic principle is conjectured to be fundamental to physics, and by extension to human cognition and perception.
