The holographic principle is a property of quantum gravity and string theories which states that the description of a volume of space can be thought of as encoded on a boundary to the region — preferably a light-like boundary like a gravitational horizon.

The holographic principle was inspired by black hole thermodynamics, which implies that the maximal entropy in any region scales with the radius squared, and not cubed as might be expected.

The holographic principle resolves the black hole information paradox within the framework of string theory.

The most rigorous realization of the holographic principle is the AdS / CFT correspondence by Juan Maldacena.

* The no cloning theorem prevents us from viewing the holographic principle for black holes as meaning we have two copies of information lying at the event horizon and the black hole interior simultaneously.

However, recent developments attempt to show that if locality is only approximate and the holographic principle is correct, the Weinberg – Witten theorem would not be valid.

This is because string theory allows for the consistent combination of quantum field theory and general relativity, agrees with general insights in quantum gravity ( such as the holographic principle and Black hole thermodynamics ), and because it has passed many non-trivial checks of its internal consistency.

As was only recently seen, by works of't Hooft, Susskind and others, a positive cosmological constant has surprising consequences, such as a finite maximum entropy of the observable universe ( see the holographic principle ).

On July 7, 2007, the character Lumi from Genki Rockets ( also the principle character from Child of Eden ) opened the Live Earth concert in Tokyo in a holographic performance, and introduced a holographic video projection of Al Gore.

Much as the study of the statistical mechanics of black body radiation led to the advent of the theory of quantum mechanics, the effort to understand the statistical mechanics of black holes has had a deep impact upon the understanding of quantum gravity, leading to the formulation of the holographic principle.

The fact that the black hole entropy is also the maximal entropy that can be obtained by the Bekenstein bound ( wherein the Bekenstein bound becomes an equality ) was the main observation that led to the holographic principle.

They point out that dark matter, dark energy and even the Pioneer anomaly are unexplained by the Standard Model of particle physics and suggest that some modification of gravity, possibly arising from Modified Newtonian Dynamics or the holographic principle.

Though not yet fully understood in general, the holographic principle is central to theories like the AdS / CFT correspondence.

Unlimited precision real numbers in the physical universe are prohibited by the holographic principle and the Bekenstein bound.

His contributions to physics include a proof that gauge theories are renormalizible, dimensional regularization, and the holographic principle.

This led to introduction of the holographic principle by him and Leonard Susskind.

Based on his black-hole thermodynamics work, Bekenstein also demonstrated the Bekenstein bound: there is a maximum to the amount of information that can potentially be stored in a given finite region of space which has a finite amount of energy ( which is similar to the holographic principle ).

It is the most successful realization of the holographic principle, a speculative idea about quantum gravity originally proposed by Gerard't Hooft and improved and promoted by Leonard Susskind.

Today, many physicists believe that the holographic principle ( specifically the AdS / CFT duality ) demonstrates that Hawking's conclusion was incorrect, and that information is in fact preserved.

The solution to the problem that concluded the battle is the holographic principle, which was first proposed by't Hooft but was given a precise string theory interpretation by Susskind.

Halman manages to upload its combined personalities into a petabyte-capacity holographic 3D storage medium and thus survives the disintegration of the monoliths.

The groove period must be on the order of the wavelength of interest ; the spectral range covered by a grating is dependent on groove spacing and is the same for ruled and holographic gratings with the same grating constant.

* holographic-written in the hand of the testator ; in many jurisdictions, the signature and the material terms of the holographic will must be in the handwriting of the testator.

The expansion of the concept of holographic, or handwritten documents must include a discussion of the effectiveness of a document in accomplishing its intended purpose.

The rule for creating a minimally acceptable " holographic " will has been agreed upon: to be indisputably without edit or revision by an outsider ( other than the author ), absolutely no mechanically printed material must be contained in the document.

To be effective as a testamentary document, a " holographic " will must be signed by its author.

Dolgoff emphasized the importance holography will play in the future and that if Gene Roddenberry wanted to be accurate he must introduce holography into his Star Trek scripts, including the concept of a holographic “ room ” for the crew to use for amusement, training, and other purposes.

Normally, a will must be signed by witnesses attesting to the validity of the testator's signature and intent, but in many jurisdictions, holographic wills that have not been witnessed are treated equally to witnessed wills and need only to meet minimal requirements in order to be probated:

Before the start of the pre-show, the television monitors describe other events taking place at the Tomorrowland Interplanetary Convention Center, including " Mission to Mars: History or Hoax " ( a tribute to the attraction that previously occupied the Alien Encounter's space ), " Championship Pet Show " (" because when it comes to your space pet, what goes down must not come up "), and " The Walt Disney Company's Pan Galactic Stock Holders Meeting " ( featuring a holographic transmission from " Lunar Disneyland — The Happiest Place Off Earth ").

( Black Lectroids appear to be Rastafarian Jamaicans, while Red Lectroids are caucasians ) The ship also sends a " thermo-pod " to Earth, with a holographic message from the Black Lectroids ' leader, John Emdall, explaining Lord Whorfin's motives and giving an ultimatum: stop Whorfin and his army or the Black Lectroids will protect themselves by staging a fake nuclear attack, causing the start of World War III.

Three years after the incident which claimed the agent's right eye, he is evaluated through a holographic simulation in which he is paired with 007 to stop Auric Goldfinger, a member of a criminal organization, from detonating a suitcase nuke inside Fort Knox.

As a result, so-called " form wills " purchased at stationery stores can constitute legally valid holographic wills provided that their material terms are completed solely in the testator's handwriting.

Julian Sands reprised the role of Jor-El in the tenth season episode " Abandoned ", appearing in the form of a holographic message that Jor-El and Lara had recorded for Kal-El shortly before his ship was launched, after Lois travels to the Fortress to confront Jor-El about his failures as a father, the message featuring Jor-El and Lara assuring their son that they have faith in him, also explaining that Jor-El's cold attitude at times stems from the fact that the original Jor-El only gave the Fortress his knowledge, holding back his emotions because he worried that he might be guided to be too easy on his son when the time came for him to face his challenges.

Jurisdictions that do not generally recognize unwitnessed holographic wills will accordingly grant exceptions to members of the armed services who are involved in armed conflicts and sailors at sea, though in both cases the validity of the holographic will expires at a certain time after it is drafted.

* Texas-a holographic will can be self-proved at creation by the testimony of two witnesses when formed ( similar to a regular will ); in addition, " uch a will may be made self-proved at any time during the testator's lifetime by the attachment or annexation thereto of an affidavit by the testator to the effect that the instrument is his last will ; that he was at least eighteen years of age when he executed it ( or, if under such age, was or had been lawfully married, or was then a member of the armed forces of the United States or of an auxiliary thereof or of the Maritime Service ); that he was of sound mind ; and that he has not revoked such instrument.
