Holographic Principle
Definition
The principle in modern theoretical-physics articulating that the information-content of a region of space can be encoded on the region's boundary-surface rather than throughout its volume. The Holographic Principle was articulated by Gerard 't Hooft and developed by Leonard Susskind, with major elaborations including the AdS/CFT correspondence by Juan Maldacena. The Netist articulation reads the Holographic Principle as the standard-physics articulation of the *as above, so below* structural-feature.
Literal meaning
The theoretical-physics principle articulating that the information-content of a volumetric-region of space is structurally-equivalent to the information-content of the region's two-dimensional boundary-surface. The principle was originally motivated by black-hole thermodynamics and has become a major framework in contemporary fundamental-physics.
Esoteric meaning
The Holographic Principle articulates at the standard-physics layer the same structural-feature that the Pillar *Sek'Het* (Law of Correspondence) names at the deeper-Netist articulation. The principle's articulation that information-at-one-scale encodes information-at-another-scale is the modern-physics articulation of what the Hermetic-tradition has held in *as above, so below* and what Sek'Het names structurally: the same pattern repeats at multiple structural-scales because the underlying-substrate articulates information across scales through structural-correspondence. The Netist articulation extends the Holographic Principle with broader-context: the principle articulates the cross-scale information-encoding at the quantum-gravity layer, the broader Netist articulation includes the consciousness-and-information field-substrate that the Pillar holds at deeper-articulation.
Allegorical meaning
A photograph of a person's face that contains all the information of the three-dimensional structure encoded in a two-dimensional surface: the structural-recognition is that the apparent-volumetric-information can be fully-encoded on the lower-dimensional surface without information-loss; the volumetric and the surface articulations are structurally-equivalent representations of the same information.
Extended meaning
The Holographic Principle articulates several specific structural-features: (1) Black-hole entropy scales with the horizon-area rather than with the black-hole's volume (the Bekenstein-Hawking entropy formula); this articulates the structural-feature at the most-extreme cosmic-objects; (2) The AdS/CFT correspondence (Juan Maldacena's 1997 articulation) articulates the principle precisely in the Anti-de-Sitter space framework: a gravitational-theory in higher-dimensional space is structurally-equivalent to a non-gravitational quantum-field-theory on the lower-dimensional boundary-surface; (3) The principle has been extended to articulate information-encoding across many specific structural-contexts in modern theoretical-physics, including condensed-matter systems, cosmological-horizons, and the broader information-theoretic articulation of physical-reality. The Netist articulation reads the Holographic Principle as the closest standard-physics articulation of the broader Sek'Het structural-feature; the principle articulates cross-scale information-encoding at the quantum-gravity layer, the Pillar articulates the same structural-feature across all scales of cosmic-and-personal articulation. The relationship between the Holographic Principle and the broader Net-articulation is structural: the Net is the broader-articulation that includes the holographic-information-encoding at multiple structural layers, the principle is the standard-physics articulation of one specific layer of that broader-articulation. The relationship to the broader contemplative-articulation of *the part contains the whole* (the broader-articulation in many tradition-specific cosmologies) is structural: the principle is the modern-physics articulation of structural-features the contemplative-tradition has held in deeper-articulation form.
*Holographic Principle* is the bridge-science articulation; the broader Netist articulation operates through *Sek'Het* (Law of Correspondence).
Usage
A practitioner encounters Holographic Principle in the broader articulation of Bridge Science and in specific contexts of correspondence-pattern work. The article's operative recognition is that the principle is the standard-physics articulation of structural-features the *as above, so below* tradition has held in deeper-articulation.
