Quantum "Weeping Angel" Effect Freezes Atoms In Place
The paradox of Schroedinger’s Cat famously demonstrates that a quantum cat sealed in a box is both alive and dead at the same time until we look inside, at which point it becomes one or the other. Suc...
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...
Confirming Einstein, scientists find 'spacetime foam' not slowing down photons from faraway gamma-ray burst
One hundred years after Albert Einstein formulated the general theory of relativity, an international team has proposed another experimental proof. In a paper published today in Nature Physics, resear...
Quantum scientists create light from vacuum
Scientists at Chalmers have succeeded in creating light from vacuum – observing an effect first predicted over 40 years ago. The results have been published in the journal Nature. In an innovative exp...
Uncertainty principle
http://www.myspace.com/acorvettes Single photons are the smallest quantities of light and, despite having no mass, have many properties in common with partic...
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 ...

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...
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 ...

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...
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...

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 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...
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...
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...
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...
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...

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...
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...
Werner Heisenberg
Werner Karl Heisenberg ([ˈhaɪzənbɛɐ̯g]; 5 December 1901 – 1 February 1976) was a German theoretical physicist and one of the key pioneers of quantum mechanics. He published his work in 1925 in a break...

Tunnel junction
In electronics, a tunnel junction is a barrier, such as a thin insulating layer or electric potential, between two electrically conducting materials. Electrons (or quasiparticles) pass through the bar...

Pair production
Pair production is the creation of an elementary particle and its antiparticle, for example an electron and its antiparticle, the positron, a muon and antimuon, or a tau and antitau. Usually it occurs...
Axion
The axion is a hypothetical elementary particle postulated by the Peccei–Quinn theory in 1977 to resolve the strong CP problem in quantum chromodynamics (QCD). If axions exist and have low mass within...
Classical and quantum conductivity
Classical and quantum mechanical views of conductivity have both described the movements of electrons in a metallic solid. The free electron gas that is present in metallic solids is the reason for an...
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...
