[103] The zero-point energy density of the vacuum, due to all quantum fields, is extremely large, even when we cut off the largest allowable frequencies based on plausible physical arguments. The vacuum state energy described by k k/2 is infinite. We can imagine them to be fluctuating about their mean value of zero. In the most general sense, the exotic matter needed to create wormholes would share the repulsive properties of the inflationary energy, dark energy or zero-point radiation of the vacuum. [184] A good example of a spontaneous phase transition that are attributed to zero-point fluctuations can be found in superconductors. The issue is whether the science can be engineered into something workable"[267]. Generally, health experts recommend eating about 0.36 grams of protein for every pound that you weigh. and that equal-time particle and field operators commute, we obtain: For the dipole oscillator under consideration it can be assumed that the radiative damping rate is small compared with the natural oscillation frequency, i.e., 0 1.

Paul Davies on the Meaning of Mach's Principle", "Weighty Implications: NASA Funds Controversial Gravity Shield", "Scientists Examine Nothing, Find Something", "Does Dark Energy Spring From the 'Quantum Vacuum? In particular Lorentz force law, which elaborates Maxwell's equations is violated by these force free vortices. shows. a measure of the strength of the electromagnetic force (where qe is the absolute value of the electronic charge and It generally predicts a slightly slower acceleration of the expansion of the universe than the cosmological constant. The expectation value of 0 in the ground state (the vacuum expectation value or VEV) is then 0 = v/2, where v = ||/. [215] Despite such criticism, FDT has been shown to be true experimentally under certain quantum, non-classical conditions. In the above expression for the change of potential energy (Equation (14.4.4)), let y f = y be an arbitrary point and y i = 0 denote the surface of the earth. [165] In the late 1880s there was a debate over the relative merits of vector analysis and quaternions. According to quantum field theory, the universe . [140] Scalar fields are predicted by the Standard Model of particle physics and string theory, but an analogous problem to the cosmological constant problem (or the problem of constructing models of cosmological inflation) occurs: renormalization theory predicts that scalar fields should acquire large masses again due to zero-point energy. With the continued accelerated expansion of the universe, the cosmos generates an energy gradient that increases the "free energy" (i.e. "[247], In 1986 the U.S. Air Force's then Rocket Propulsion Laboratory (RPL) at Edwards Air Force Base solicited "Non Conventional Propulsion Concepts" under a small business research and innovation program. Classically, this would be a state of motionlessness, but quantum . ", "Anti-Gravity Propulsion Comes "Out of the Closet", "Quantum Particles Seen Distorting Light From a Neutron Star", "Inertia Theory: Magic Roundabout. However, this elimination does not mean that the vacuum field has been rendered unimportant or without physical consequences. [117], An interesting hypothetical side effect of the Casimir effect is the Scharnhorst effect, a hypothetical phenomenon in which light signals travel slightly faster than c between two closely spaced conducting plates. With regard to the gravitational attraction that is described so well by Einstein's theory, its fundamental nature is still not well understood. [139] One difficulty with this assumption is that the zero-point energy of the vacuum is absurdly large compared to the observed cosmological constant. Note that the dynamics of the ions is still classical, although the force is evaluated quantum mechanically. [240][241][242][243][244][245] Referring to Wallace's patents, a New Scientist article in 1980 stated "Although the Wallace patents were initially ignored as cranky, observers believe that his invention is now under serious but secret investigation by the military authorities in the USA. One may query what this has to do with zero-point energy. Classically, a dipole in the vacuum is not acted upon by any "external" field: if there are no sources other than the dipole itself, then the only field acting on the dipole is its own radiation reaction field. However, a signal's energy does have important practical significance. Independently of this, from 1991 to 1993 Ning Li and Douglas Torr published a number of articles[257][258][259] about gravitational effects in superconductors. Most serious scientific research in this area depends on the theorized anti-gravitational properties of antimatter (currently being tested at the alpha experiment at CERN) and/or the effects of non-Newtonian forces such as the gravitomagnetic field under specific quantum conditions. [195] Others have since claimed to exploit zero-point or vacuum energy with a large amount of pseudoscientific literature causing ridicule around the subject. ( Zero-point energy or the zero-point field (ZPF), also known as ground state energy, is an expansive topic that particle physicists based on the Heisenberg Uncertainty Principle. [101] Indeed, such treatment could create a problem at a deeper, as of yet undiscovered, theory. Quoting from their third paper: "It is shown that the coherent alignment of lattice ion spins will generate a detectable gravitomagnetic field, and in the presence of a time-dependent applied magnetic vector potential field, a detectable gravitoelectric field." There's no physical significance to zero energy. No evidence of quintessence is yet available, but it has not been ruled out either. [230], In 1963 Robert Forward, a physicist and aerospace engineer at Hughes Research Laboratories, published a paper showing how within the framework of general relativity "anti-gravitational" effects might be achieved. To use it in any significant way, as per the 2nd law of Thermodynamics, you'd have to create a small zone featuring a lower-energy false vacuum somewhere. 'Net Zero' means achieving a balance between the amount of emissions produced and those removed from the atmosphere in order to reduce global warming. The zero-point energy of empty space is inconsistent with a value of zero. However this is not the whole story, in reality energy is not so arbitrarily defined: in general relativity the seat of the curvature of spacetime is the energy content and there the absolute amount of energy has real physical meaning. One property of the zero vector is that it is known as the "additive identity". [166] It was concluded that there was no need for the greater physical insights provided by the quaternions if the theory was purely local in nature. All in all, depends on the energy scale characteristic of the process under study, and also on details of the renormalization procedure. If the birefringence had been caused by light passing through interstellar gas or plasma, the effect should have been no more than 1%. Most modern physicists believe that it is extremely unlikely for humanity to extract usable energy from zero-point energy. [82], There have been a growing number of papers showing that in some instances the classical laws of thermodynamics, such as limits on the Carnot efficiency, can be violated by exploiting negative entropy of quantum fluctuations. [262][263] In 1997 Li published a paper attempting to replicate Podkletnov's results and showed the effect was very small, if it existed at all. Some would say it is the gateway that connects the space-time of Mind with the infinite intelligence of God. [169][170][171][172], A good example of nonlinear electromagnetics is in high energy dense plasmas, where vortical phenomena occur which seemingly violate the second law of thermodynamics by increasing the energy gradient within the electromagnetic field and violate Maxwell's laws by creating ion currents which capture and concentrate their own and surrounding magnetic fields. The Hamiltonian for the oscillator plus the field with which it interacts is: This has the same form as the corresponding classical Hamiltonian and the Heisenberg equations of motion for the oscillator and the field are formally the same as their classical counterparts. the ground state or zero-point energy) but without any associated rise in temperature. Another way of saying it is that it is the change in potential which has physical significance. The ignoring of the whole zero-point energy is often encouraged for all practical calculations. satisfied by the field in the (source free) vacuum. [236], From 1971 to 1974 Henry William Wallace, a scientist at GE Aerospace was issued with three patents. Some benefits of using the bracelet includes: Increased activity. ", "Evidence for vacuum birefringence from the first optical-polarimetry measurement of the isolated neutron star RXJ1856.53754", "ber die Begrndung das Gesetzes des schwarzen Strahlung", "Foundational Electrodynamics and Beltrami Vector Fields", "Direct Sampling of Electric-Field Vacuum Fluctuations", On the Elecrodynamics of the Vacuum on the Basis of the Quantum Theory of the Electron, "Research in a Vacuum: DARPA Tries to Tap Elusive Casimir Effect for Breakthrough Technology", "Research Team Claims to Have Directly Sampled Electric-Field Vacuum Fluctuations", "Dynamical Casimir Effect in a Josephson Metamaterial", the issue of vacuum energy and dark energy, https://en.wikipedia.org/w/index.php?title=Zero-point_energy&oldid=1142291057, This page was last edited on 1 March 2023, at 16:06. This term is the Zero Point Field or ZPF. In essence, it has been asserted that Beltrami plasma vortex structures are able to at least simulate the morphology of Type I and Type II superconductors. [266], In 2002 Phantom Works, Boeing's advanced research and development facility in Seattle, approached Evgeny Podkletnov directly. But this . "[246] A further reference to Wallace's patents occur in an electric propulsion study prepared for the Astronautics Laboratory at Edwards Air Force Base which states: "The patents are written in a very believable style which include part numbers, sources for some components, and diagrams of data. At X-ray wavelengths the polarization from the quantum fluctuations should be near 100%. 9. The Heisenberg equation for ak is found similarly from the Hamiltonian to be: In deriving these equations for x, p, and ak we have used the fact that equal-time particle and field operators commute. Enhance Aura. ', "Casimir Forces and Quantum Electrodynamical Torques: Physics and Nanomechanics", "Is There Evidence for Cosmic Anisotropy in the Polarization of Distant Radio Sources? It is predicted the speed at which light travels through the vacuum depends on its direction, polarization and the local strength of the magnetic field. [80] Such a theory has met with resistance: Macdonald (1962)[210] and Harris (1971)[211] claimed that extracting power from the zero-point energy to be impossible, so FDT could not be true. However, it has been questioned in a series of journal articles whether the quantum mechanically canonised London equations can be given a purely classical derivation. For instance the Heisenberg equations for the coordinate x and the canonical momentum p = m +eA/c of the oscillator are: since the rate of change of the vector potential in the frame of the moving charge is given by the convective derivative. For nonrelativistic motion we may neglect the magnetic force and replace the expression for m by: Above we have made the electric dipole approximation in which the spatial dependence of the field is neglected. an ordinary number rather than an operator) and commutes with ak. There are many possible origins of this non-zero value, but its ultimate cause still remains a mystery. [1] [2] Devices allegedly suppressed include perpetual motion machines, cold fusion generators, torus -based generators, reverse . A phenomenon that is commonly presented as evidence for the existence of zero-point energy in vacuum is the Casimir effect, proposed in 1948 by Dutch physicist Hendrik Casimir, who considered the quantized electromagnetic field between a pair of grounded, neutral metal plates. The bond-dissociation energy (BDE, D 0, or DH) is one measure of the strength of a chemical bond AB.It can be defined as the standard enthalpy change when AB is cleaved by homolysis to give fragments A and B, which are usually radical species. [141] Many physicists also believe that inflation explains why the Universe appears to be the same in all directions (isotropic), why the cosmic microwave background radiation is distributed evenly, why the Universe is flat, and why no magnetic monopoles have been observed. [250] Building on the work of Thorne, in 1994 Miguel Alcubierre[251] proposed a method for changing the geometry of space by creating a wave that would cause the fabric of space ahead of a spacecraft to contract and the space behind it to expand (see Alcubierre drive). The enthalpy change is temperature-dependent, and the bond-dissociation energy is often defined to be the enthalpy change of the homolysis at 0 . First, is the divergence a real one such that the zero-point energy really is infinite? In 2014 NASA's Eagleworks Laboratories announced that they had successfully validated the use of a Quantum Vacuum Plasma Thruster which makes use of the Casimir effect for propulsion. Yet, in theory, large nonlinear self-interaction of light due to quantum fluctuations should lead to this principle being measurably violated if the interactions are strong enough. The Higgs mechanism, Hawking Radiation and the Unruh effect are also theorized to be dependent on zero-point vacuum fluctuations, the field contribution being an inseparable parts of these theories. It is difficult to judge the physical reality of infinite zero-point energies that are inherent in field theories, but modern physics does not know any better way to construct gauge-invariant, renormalizable theories than with zero-point energy and they would seem to be a necessity for any attempt at a unified theory. It may be that inflation caused baryogenesis, the hypothetical physical processes that produced an asymmetry (imbalance) between baryons and antibaryons produced in the very early universe, but this is far from certain.

The consequences of this discovery probably will also have to be realised on a longer timescale. [196] In 1984 Robert Forward[199] published work showing how a "vacuum-fluctuation battery" could be constructed. [115] published experimental proof that (as predicted in 1961[116]) the Casimir force could also be repulsive as well as being attractive. [273], Speculated involvement in other phenomena. This energy is called the vacuum energy or zero-point energy. 101 2. [105][106][107][108][109] That changed in 1997 with Lamoreaux[110] conclusively showing that the Casimir force was real. E0(t) is the free or zero-point field acting on the dipole. The Standard Model hypothesises a field called the Higgs field (symbol: ), which has the unusual property of a non-zero amplitude in its ground state (zero-point) energy after renormalization; i.e., a non-zero vacuum expectation value. To find the classical ground state, set the velocity to zero to minimize the kinetic energy, (1/2)m v 2, and put the particle at the point where it has the lowest potential energy V(x). Yet, if this energy uniformly permeates all of space-time, it is not directly observable. The concept can be somewhat justified on general relativistic grounds since rotating frames of time varying fields are expected to emit gravitational waves. A similar result is easily worked out for the case of a free particle instead of a dipole oscillator.[98]. If the potential energy at one point is -30 and at another point is -20, that is exactly the same, physically, as if the potential energy at the first point were +1000 and at the second point +1010. It's truly an otherworldly technology and people like Edgar Mitchell knew about it. The military may now regret that the patents have already been granted and so are available for anyone to read. In 1993 Scharnhorst and Barton[118] showed that the speed of a photon will be increased if it travels between two Casimir plates, an example of negative energy. "Zero point" energy is the smallest amount of energy that something can have. There is basic science there. [182] For example, it has been estimated that human body is 10,000 times more effective at dissipating energy per unit of mass than the sun.[183]. [229] In certain conditions the gravitomagnetic field can be repulsive. It is based on a revised formulation of the spectral distribution of the zero point energy, for an ensemble in a defined statistical . ", Nevertheless, as Jaffe himself notes in his paper, "no one has shown that source theory or another S-matrix based approach can provide a complete description of QED to all orders." The vacuum state, like all stationary states of the field, is an eigenstate of the Hamiltonian but not the electric and magnetic field operators. And this can be checked: n a clever experiment, the energy in a small region can be made to have a measurable impact called the "Casimir . . The summation becomes approximately the integral: for high values of v. It diverges proportional to v4 for large v. There are two separate questions to consider. It's a byproduct of the fact that subatomic particles don't really. Physicists overwhelmingly reject any possibility that the zero-point energy field can be exploited to obtain useful energy (work) or uncompensated momentum; such efforts are seen as tantamount to perpetual motion machines. [120] The shift of about 4.38106eV is roughly 107 of the difference between the energies of the 1s and 2s levels, and amounts to 1,058MHz in frequency units. In physics, the zero-point energy is the lowest possible energy that a quantum mechanical physical system may possess; it is the energy of the ground state of the system. : Increased activity some would say it is the gateway that connects the space-time of Mind with the continued expansion...
