Quantum Consciousness . Stuart Hameroff The boundary between the quantum and classical worlds is unclear, and the transition between the two is commonly described as quantum state reduction, collapse of the wave function, or decoherence. Early quantum experiments led to the conclusion that quantum superpositions persisted until measured or observed by a conscious observer, that "consciousness collapsed the wave function". The theory of decoherence reconciles the Copenhagen interpretation with quantum superpositions in the absence of measurement or conscious observation. www.quantumconsciousness.org /overview.html   (2321 words)

GUTs: Quantum Foam   (Site not responding. Last check: 2007-10-15) Quantum mechanics says that even the gravitational field is effected by these fluctuations. General relativity states that there is a zero gravitational field in empty space, but quantum mechanics say it averages zero, and fluctuates more and more wildly on a smaller and smaller scale. According to quantum mechanics, if you could magnify empty space enough, you would find that it is not flat at all but tangled, distorted, bubbly, and tumultuous. library.thinkquest.org /25886/yquanfoam.htm   (127 words)

Quantum Foam Quantum fl holes form and vanish in a span of time of 10-23 seconds; highly curved and convoluted regions of space in ant physically allowed configuration have a similarly brief existence. To stabilize the wormhole pulled from the quantum foam, preventing its immediate recollapse, Morris, Thorne, and Yurtsever propose to use an electric field of such enormous strength that it creates enough energy in the mouth of the wormhole to force it to remain open. At the level of 'quantum foam', where subatomic particles dance into and out of existence in countless numbers, worm-holes are thought to be extremely common. quantumfoam.tripod.com /q-foam.html   (1624 words)

Quantum foam Quantum gravity is needed to describe the first instants of creation, when quantum fluctuations ruled the Universe, and it could even lead us to a full understanding of how our Universe works-the elusive Theory of Everything that will tie all the forces of nature together. Quantum mechanics describes how particles interact with each other to generate all but one of the forces in nature. All fledgling theories of quantum gravity also make a more general and even weirder prediction: the structure of space and time is very different from the gentle curves predicted by general relativity. www.ldolphin.org /qfoam.html   (2132 words)

NASA - Einstein Right About Speed of Light General relativity is the theory of gravity on a large scale, while quantum mechanics, developed independently in the early 20th century, is the theory of the atom and subatomic particles on a very small scale. These unifying theories -- such as quantum gravity or string theory -- may involve the invocation of extra dimensions of space and also violations of Einstein's special theory of relativity, such as the speed of light being the maximum attainable velocity for all objects. A gamma-ray burst, for example, is at such a great distance that the differences in the speeds of photons in the burst, depending on their energy, might be measurable -- as the quantum foam of space may act to slow light which has been traveling to us for billions of years. www.nasa.gov /centers/goddard/news/topstory/2003/1212einstein.html   (1467 words)

Quantum Consciousness Quantum electrodynamics and quantum field theory predict virtual particle/waves (or photons) that pop into and out of existence, creating quantum "foam" in their wake. Quantum electodynamics (QED) predicts a foam of erupting and collapsing virtual particles which may be visualized as topographic distortions of the fabric of spacetime. Quantum states in microtubules may link to those in microtubules in other neurons and glia by tunneling through gap junctions, permitting extension of the quantum state throughout significant volumes of the brain. www.quantumconsciousness.org /presentations/whatisconsciousness.html   (5512 words)

A quantum foam absorber: theoretically possible? I used quantum foam in my dish washing machine and I have to say I was disappointed with the result: it leaves traces on the glasswork. I believe the quantum foam is produced by a primary quantum process, whereas the VPF is produced from the quantum foam by a secondary process. Remember the universe *is* all a vacuum with a few quantum fields, and water molecules, the element of your kettle are all excitations of the electron field. www.physicsforums.com /showthread.php?t=82467   (1007 words)

Alignment Theory. New Quantum Relativity Theory of Everything Relativity and Quantum mechanics describe the effects, it is suggested that Alignment theory is the mechanism. Quantum foam is a simple field where each fleeting Plank-scale virtual particle has a direction vector and an amplitude of energy. The "curvature" of space-time is an outcome of alignments of quantum foam. www.becomereal.com /quantum_relativity.htm   (2052 words)

[gr-qc/0203015] Process Physics: From Quantum Foam to General Relativity Previous progress in process physics included the demonstration that space and quantum physics are emergent and unified, with time a distinct non-geometric process, that quantum phenomena are caused by fractal topological defects embedded in and forming a growing three-dimensional fractal process-space, which is essentially a quantum foam. Other features of the emergent physics were: quantum field theory with emergent flavour and confined colour, limited causality and the Born quantum measurement metarule, inertia, time-dilation effects, gravity and the equivalence principle, a growing universe with a cosmological constant, fl holes and event horizons, and the emergence of classicality. Quantum gravity, as manifested in the emergent Quantum Homotopic Field Theory of the process-space or quantum foam, is logically prior to the emergence of the general relativity phenomenology, and cannot be derived from it. www.arxiv.org /abs/gr-qc/0203015   (237 words)

Elementary Particles Quantum theory was developed in 1925-1926 by Erwin Schrodinger, Werner Heisenberg, and others in response to many inconsistences between expermental data and classical theories. General relativity and quantum theory describe two extreme of physics - the former is on the very large scale up to the whole universe, while the latter is on the smallest possible scale down to the size of elementary particles. Unlike the superstring theory, loop quantum gravity is completely unperturbative and is also background-independent (geometry of spacetime is not fixed), and appears to lead to a pregeometry in which space and time are derived concepts (instead of being a pre-defined entity). universe-review.ca /F15-particle.htm   (10364 words)

Spin networks, spin foams and loop quantum gravity Loop quantum gravity is a theory that results from the canonical quantization of general relativity. Quantum gravity is one of the focus areas at the newly founded Perimeter Institute in Waterloo, Ontario, Canada, which has recruited Lee Smolin as well as several other influential researchers in quantum gravity.

Quantum Foam and Loop Quantum Gravity It is called theory of loop quantum gravity, which postulates that the minimum linear size of space is of the order of the Planck length. Recent loop quantum gravity calculations indicate that the big bang is actually a big bounce; before the bounce the universe was rapidly contracting. Loop quantum gravity is completely unperturbative and is also background-independent (geometry of spacetime is not fixed), and appears to lead to a pregeometry in which space and time are derived concepts (instead of being a pre-defined entity). universe-review.ca /R01-07-quantumfoam.htm   (1110 words)

fUSION Anomaly. Quantum Mechanics quantum mechanics or quantum theory, branch of mathematical physics that deals with the emission and absorption of energy by matter and with the motion of material particles. According to the quantum theory, energy is emitted and absorbed in a small packet, called a quantum (pl. quanta), which in some situations behaves as particles of matter do; particles exhibit certain wavelike properties when in motion and are no longer viewed as localized in a given region but as spread out to some degree. Quantum mechanics, the final mathematical formulation of the quantum theory, was developed during the 1920s. fusionanomaly.net /quantummechanics.html   (1928 words)

space These photon holes in the space foam can be understood to be equivalent to matter (dark matter), hence, as the Universe expands more and more of this dark matter arises (which may accumulate within a galaxy) to begin to cease the expansion. Photon holes within the quantum foam that clump in certain areas may be the framework that defines the geometry of space. That is, each piece of quantum space may be abstracted to be a part of the larger whole of space. www.johnkharms.com /space.htm   (5775 words)

What is 'quantum foam'?   (Site not responding. Last check: 2007-10-15) This means that the state of this field is, at some level, uncertain and described by quantum mechanics. Wheeler imagined that this indeterminacy for space-time required that at the so-called Planck Scale of 10^-33 centimeters and 10^-43 seconds, space-time has a foaminess to it with sudden changes in its geometry into a wealth of complex shapes and textures. The problem is that we have no evidence that 1) gravity is a quantum field and 2) that space-time has this type of structure at these scales. www.astronomycafe.net /qadir/ask/a11792.html   (241 words)

unification, spacetime foam, quantum vacuum, quantum fluctuations It is the quantum vacuum that such characteristics emerge from, particles `stand-out' from the vacuum, waves `undulate' on the underlying vacuum, and leave their signature on objects in the real Universe. In this sense, the Universe is not filled by the quantum vacuum, rather it is `written on' it, the substratum of all existence. The uncertainty and unpredictability of the quantum world is manifested in the fact that whatever can happen, does happen (this is often called the principle of totalitarianism, that if a quantum mechanical process is not strictly forbidden, then it must occur). zebu.uoregon.edu /~js/ast123/lectures/lec17.html   (2014 words)

Quantum Space And GTR If one pictures space fundamentally as mobile particles, a frothing foam that is held in place (similar to a grid) by the negative radiation pressures of the vacuum, the forces of gravity and electromagnetic might be understood as one in the same. The electromagnetic field is in-essence space itself, a field of quantum foam, the most important element of which are the photon holes. There can be no position or velocity of quantum space that can be said to be not moving, whilst everything else is. The quantum foam space-grid is frothing with energy and movement, particularly close to galaxies. www.johnkharms.com /GTR.htm   (4108 words)

Quantum foam - The Hyperspace Forums On the detectability of quantum spacetime foam with gravitational-wave interferometers - We show how the limit shape of the melting crystal emerges as the average geometry and topology of the quantum foam at the string scale. The geometry is classical at large length scales, modified to a smooth limit shape dictated by mirror geometry at string scale and is a quantum foam at area scales g_s \alpha'. www.mkaku.org /forums/showthread.php?t=149   (2674 words)

Egg Files V: Quantum Foam Eventually I moved on to the quantum foam of the food world, the dish that inspires as much fear as appetite, the soufflé. Speaking of foam, it's a good thing I keep individually frozen egg whites on the premises at all times because just about every soufflé recipe on earth calls for more whites than yolks. The worst mistake that novice soufflé-ers make is over-beating their egg whites, that is, stretching the protein so much that the resulting foam isn't flexible enough to standup to the expansion of the oven. www.goodeatsfanpage.com /Season6/Souffle/SouffleTrans.htm   (2685 words)

Feynman to be named as the most outstanding of them).

Given the First Law of Thermodynamics: that you can't get something from nothing. Where did all the stuff in the ... This quantum foam is made of particles and micro-fl holes popping in and out of existence, apparently in contravention of the second law of thermodynamics, they appear out of nothing with energy, then disappear again just as quickly. It is possible that during the big bang, fl holes the size of a nucleus popped into existence due to the quantum foam. And as for how the universe actually came into being itself, it is believed that also in the quantum foam, virtual space-time bubbles also continually pop in and out of existence, like virtual particles, only to disappear again. www.physlink.com /Education/AskExperts/ae332.cfm   (897 words)

Physics: Quantum Foam I was wondering how exactly we are able to determine that there is a such thing as quantum foam, or do we just have to believe that it is there for the math to work? Quantum gravity generally is a non experimental field. So things like strings and quantum foam are mathematical hypothesis with no experimental proof, and the math seems to work. en.allexperts.com /q/Physics-1358/Quantum-Foam.htm   (248 words)

Post-Quantum Geometrodynamics of Matter-Mind This was the same situation Einstein faced in 1915 in developing the general theory of relativity in which gravitation is the direct back-reaction of matter on the space-time geometry causing it to "warp" or "curve" away from its "flatness" in special relativity. In quantum geometrodynamics all elementary particles are naked singularity wormholes whose mouths are a Compton wavelength across at Level 2 for low energy probes.

Spin Networks, Spin Foams, and Quantum Gravity   (Site not responding. Last check: 2007-10-15) But to better understand the dynamical aspects of quantum gravity, we would also like a model for 'quantum 4-geometries'. A spin foam is a 2-dimensional cell complex with faces labeled by representations and edges labeled by intertwining operators; generically, any slice of a spin foam gives a spin network.

zero-point energy from hyperspace meets the quantum foam Quantum foam can be seen as tiny bubbles of energy arising from the fabric of space. An interaction of these massless structures (that might compose space on a very microscopic level)with a hyperspatial energy flux(zero point energy field) that is orthogonal to our 3D-space may exist and it is constantly producing an infinite variety of geometrical "energy" structures.
