'''Zero-point energy''', also called ''quantum vacuum zero-point energy'', is the lowest possible [[energy]] that a [[Quantum Mechanics|quantum mechanical]] physical system may have; it is the energy of its ground state. All quantum mechanical systems undergo fluctuations even in their ground state and have an associated zero-point energy, a [[consequence]] of their [[wave]]-like nature. The [[uncertainty]] principle requires every physical system to have a zero-point energy greater than the minimum of its classical potential well. This results in [[motion]] even at [https://en.wikipedia.org/wiki/Absolute_zero absolute zero]. For example, [https://en.wikipedia.org/wiki/Liquid_helium liquid helium] does not freeze under atmospheric pressure at any temperature because of its zero-point energy.

The concept of zero-point energy was developed in Germany by [https://en.wikipedia.org/wiki/Albert_Einstein Albert Einstein] and [https://en.wikipedia.org/wiki/Otto_Stern Otto Stern] in 1913, as a corrective term added to a zero-grounded formula developed by [https://en.wikipedia.org/wiki/Max_Planck Max Planck] in 1900. The term zero-point energy originates from the German Nullpunktsenergie. An alternative form of the German term is Nullpunktenergie (without the "s").

[https://en.wikipedia.org/wiki/Vacuum_energy Vacuum energy] is the zero-point energy of all the fields in space, which in the [https://en.wikipedia.org/wiki/Standard_Model Standard Model] includes the [[electromagnetic]] field, other gauge fields, fermionic fields, and the Higgs field. It is the energy of the vacuum, which in quantum field theory is defined not as empty space but as the ground state of the fields. In cosmology, the vacuum energy is one possible explanation for the [https://en.wikipedia.org/wiki/Cosmological_constant cosmological constant]. A related term is zero-point field, which is the lowest energy state of a particular field.

As a scientific [[concept]], the existence of ''zero-point energy'' is not [[controversial]], although the ability to harness it is. Over the years, there have been numerous claims of devices capable of extracting usable zero-point energy. None of the claims have ever been [[confirmed]] by the scientific community at large, and most of these claims are dismissed either by default, after third-party inspection of such a device or based on disbelief in the viability of a technical [[design]] and theoretical corroboration. Current claims to zero-point-energy-based power generation systems are considered [[pseudoscience]] by the scientific community at large and [[skeptics]] usually dismiss efforts to harness zero-point energy by default. Nevertheless, a document released by the [https://en.wikipedia.org/wiki/National_Ground_Intelligence_Center NGIC] shows there is ongoing worldwide [[research]] into zero-point energy, particular in China, Germany, Russia and Brazil. An analyst of the [https://en.wikipedia.org/wiki/Defense_Intelligence_Agency DIA] has indicated that research into successfully harnessing zero-point energy for energy generation [[purposes]] is a serious concern inside the intelligence community.[https://en.wikipedia.org/wiki/Zero-point_energy]
