Zero-point energy
Zero-point energy, also called quantum vacuum zero-point energy, is the lowest possible energy that a quantum mechanical physical system may have; it is the energy of its ground state. All quantum mec...

Documentary On Top Secret Antigravity Vehicle Released
July 30, 2015 - A documentary on the alleged true story of a man who believes he gained inside knowledge about a top secret antigravity spaceship has recently been released, despite the death of the m...
Hutchison demonstrates Zero Point Energy - YouTube
Jun 19, 2008 ... A man demonstrating zero point energy on different objects.
Ground state
The ground state of a quantum mechanical system is its lowest-energy state; the energy of the ground state is known as the zero-point energy of the system. An excited state is any state with energy gr...
Vacuum state
In quantum field theory, the vacuum state (also called the vacuum) is the quantum state with the lowest possible energy. Generally, it contains no physical particles. Zero-point field is sometimes use...
Vacuum expectation value
In quantum field theory the vacuum expectation value (also called condensate or simply VEV) of an operator is its average, expected value in the vacuum. The vacuum expectation value of an operator O i...
Quantum fluctuation
The video of an experiment showing vacuum fluctuations (in the red ring) amplified by spontaneous parametric down-conversion.In quantum physics, a quantum fluctuation (or quantum vacuum fluctuation ...
Quantum tunnelling
Quantum tunnelling or tunneling (see spelling differences) refers to the quantum mechanical phenomenon where a particle tunnels through a barrier that it classically could not surmount. This plays an ...

Unruh effect
The hypothetical Unruh effect (or sometimes Fulling–Davies–Unruh effect) is the prediction that an accelerating observer will observe black-body radiation where an inertial observer would observe none...
Quantum foam
Quantum foam (also referred to as space-time foam) is a concept in quantum mechanics devised by John Wheeler in 1955. The foam is supposed to be conceptualized as the foundation of the fabric of the u...
Quantum annealing
Quantum annealing (QA) is a metaheuristic for finding the global minimum of a given objective function over a given set of candidate solutions (candidate states), by a process using quantum fluctuatio...

Scharnhorst effect
The Scharnhorst effect is a hypothetical phenomenon in which light signals travel faster than c between two closely spaced conducting plates. It was predicted by Klaus Scharnhorst of the Humboldt Univ...
Uncertainty principle
In quantum mechanics, the uncertainty principle, also known as Heisenberg's uncertainty principle, is any of a variety of mathematical inequalities asserting a fundamental limit to the precision with ...

QED vacuum
The quantum electrodynamic vacuum or QED vacuum is the field-theoretic vacuum of quantum electrodynamics. It is the lowest energy state (the ground state) of the electromagnetic field when the fields ...

QCD vacuum
The QCD vacuum is the vacuum state of quantum chromodynamics (QCD). It is an example of a non-perturbative vacuum state, characterized by infinitely many non-vanishing condensates such as the gluon co...
Virtual particle
In physics, a virtual particle is an explanatory conceptual entity that is found in mathematical calculations about quantum field theory. It refers to mathematical terms that have some appearance of r...
Superfluid vacuum theory
Superfluid vacuum theory (SVT), sometimes known as the BEC vacuum theory, is an approach in theoretical physics and quantum mechanics where the fundamental physical vacuum (non-removable background) i...
Vacuum energy
Vacuum energy is an underlying background energy that exists in space throughout the entire Universe. One contribution to the vacuum energy may be from virtual particles which are thought to be partic...
Vacuum Rabi oscillation
A vacuum Rabi oscillation is a damped oscillation of an initially excited atom coupled to an electromagnetic resonator or cavity in which the atom alternately emits photon(s) into a single-mode electr...
Spontaneous symmetry breaking
Spontaneous symmetry breaking is a mode of realization of symmetry breaking in a physical system, where the underlying laws are invariant under a symmetry transformation, but the system as a whole cha...

Casimir effect
A water wave analogue of the Casimir effect. Two parallel plates are submerged into colored water contained in a sonicator. When the sonicator is turned on, waves are excited imitating vacuum fluctu...

Quantum noise
In physics, quantum noise refers to the uncertainty of a physical quantity, due to its quantum origin. In certain situations, quantum noise appears as shot noise; for example, most optical communicati...
Vacuum genesis
Vacuum genesis (zero-energy universe) is a scientific theory about the Big Bang that states that the universe began as a single particle arising from an absolute vacuum, similar to how virtual particl...
