PS - I think Jack is really on to something now. He can derive GR, and hence all of classical gravitation, from a simple quantum model of the vacuum as a two component (Ginzburg-Landau - "GL") superfluid of virtual fermion-antifermion pairs.
His new theory solves the cosmological constant problem: It predicts Lambda fluctuating slightly around zero (as is observed) instead predicting lambda of around 10^66 cm^-1 as does naive QED and superstring theory. It solves the dark matter problem: dark matter is where the "normal fluid" component of the GL fluid dominates the mixture. It solves the dark energy problem: dark energy is the converse situation - where the superfluid component dominates. It solves the inflation / arrow of time problem: the energy and the negentropy for inflation are released when the initial unstable primordial "false-vacuum" state undergoes a phase transition to the present GL state consisting of virtual e+ e- pairs.
His new theory shows how spacetime (3+1 dimensions) emerges from the large-N dimensional configuration space of quantum mechanics: through the emergence of an order parameter, in this case the giant quantum wavefunction of the cosmic GL superfluid wavefunction whose long-range order (ODLRO) correlates different positions in space and time.
Inspired by the work of Hagen Kleinert, the gradient of this order parameter, and its gradient's gradient (tensor), when expressed using the formalism of moving Cartan frames or Vierbeins, reproduces Einstein's equation. Gravity emerges from QM, without needing quantization itself.
The allowable broken symmetries of this order parameter can explain effects like the Pioneer anomaly, the dark massive galactic halos, and the micro-Kerr-black hole model of elementary particles. When coupled with the approaches of Ray Chiao and perhaps Chapline/Laughlin it may allow the control of gravity and circumvention of the spacetime stiffness barrier.

Jack,
Your solid He4 superfluid paper is wonderful! You actually once did something of very great importance - and apparently you didn't realize this. This paper is a precursor to quantum gravity, and much more important in that regard than string theory (you can quote me).

Message from Stanford University Physics Professor, Leonard Susskind

"To whom it may concern,
The Glogower Susskind Paper of 1963 which introduced phase operators for a quantum oscillator was in direct response to discussions between Glogower, Susskind and Jack Sarfatti. Sarfatti's contributions were significant. The correct attribution should be to the "Glowgower, Sarfatti, Susskind" operators.
Sincerely
Leonard Susskind"

latest ideas re: quantum foam (Score: 1) by vlad on Wednesday, April 06, 2005 @ 22:02:46 UTC (User Info | Send a Message) http://www.zpenergy.com | On Apr 5, 2005, at 6:24 PM, Gary S. Bekkum wrote:
If Simon is interested in some of the latest ideas re: quantum foam, he might wish to take a look at the following:
From computation to black holes and space-time foam
http://arxiv.org/abs/gr-qc/0006105
Author: Y. Jack Ng (University of North Carolina at Chapel Hill)
Comments: A misidentification of computer speeds is corrected. Our results for black hole computation now agree with those given by S. Lloyd. All other conclusions remain unchanged
Journal-ref: Phys.Rev.Lett. 86 (2001) 2946-2949; Erratum-ibid. 88 (2002) 139902
We show that quantum mechanics and general relativity limit the speed $ ilde{
u}$ of a simple computer (such as a black hole) and its memory space $I$ to $ ilde{
u}^2 I^{-1} lsim t_P^{-2}$, where $t_P$ is the Planck time. We also show that the life-time of a simple clock and its precision are similarly limited. These bounds and the holographic bound originate from the same physics that governs the quantum fluctuations of space-time. We further show that these physical bounds are realized for black holes, yielding the correct Hawking black hole lifetime, and that space-time undergoes much larger quantum fluctuations than conventional wisdom claims -- almost within range of detection with modern gravitational-wave interferometers.
Clocks, computers, black holes, spacetime foam, and holographic principle
http://arxiv.org/abs/hep-th/0010234
Author: Y. Jack Ng (University of North Carolina at Chapel Hill) Comments: 3 LateX pages (2 columns); to appear in Proceedings of conference held at the Chinese University of Hong Kong (July 31 - August 4, 2000)
What do simple clocks, simple computers, black holes, space-time foam, and holographic principle have in common? I will show that the physics behind them is inter-related, linking together our concepts of information, gravity, and quantum uncertainty. Thus, the physics that sets the limits to computation and clock precision also yields Hawking radiation of black holes and the holographic principle. Moreover, the latter two strongly imply that space-time undergoes much larger quantum fluctuations than what the folklore suggests --- large enough to be detected with modern gravitational-wave interferometers through future refinements.
Quantum Foam
http://arxiv.org/abs/gr-qc/0401015
Authors: Y. Jack Ng (University of North Carolina) Comments: 20 pages, 3 figures, talk given at the 10th Marcel Grossman Meeting (Rio de Janeiro, July 20 - 26, 2003)
Quantum foam, also known as spacetime foam, has its origin in quantum fluctuations of spacetime. Its physics is intimately linked to that of black holes and computation. Arguably it is the source of the holographic principle which severely limits how densely information can be packed in space. Various proposals to detect the foam are briefly discussed. Its detection will provide us with a glimpse of the ultimate structure of space and time.
Spacetime foam
http://arxiv.org/abs/gr-qc/0201022
Author: Y. Jack Ng (University of North Carolina) Comments: 7 pages, LaTeX; will appear in the Dec. 2002 special issue of Int. J. Mod. Phys. D (this essay received an honorable mention in the GRF essay contest) Journal-ref: Int.J.Mod.Phys. D11 (2002) 1585-1590
Spacetime is composed of a fluctuating arrangement of bubbles or loops called spacetime foam, or quantum foam. We use the holographic principle to deduce its structure, and show that the result is consistent with gedanken experiments involving spacetime measurements. We propose to use laser-based atom interferometry techniques to look for spacetime fluctuations. Our analysis makes it clear that the physics of quantum foam is inextricably linked to that of black holes. A negative experimental result, therefore, might have non-trivial ramifications for semiclassical gravity and black hole physics.
Quantum Foam and Quantum Gravity Phenomenology
http://arxiv.org/abs/gr-qc/0405078
Authors: Y. Jack Ng (University of North Carolina) Comments: 29 pages, 4 figures, lectures given at the 40th Karpacz Winter School on Theoretical Physics (Poland, Feb. 2004), submitted to Lect. Notes Phys
Spacetime undergoes quantum fluctuations, giving rise to spacetime foam, a.k.a. quantum foam. We discuss some properties of spacetime foam, and point out the conceptual interconnections in the physics of quantum foam, black holes, and quantum computation. We also discuss the phenomenology of quantum foam, and conclude that it may be difficult, but by no means impossible, to detect its tiny effects in the not-too-distant future.
Spacetime Foam, Holographic Principle, and Black Hole Quantum Computers
http://arxiv.org/abs/gr-qc/0403057
Authors: Y. Jack Ng, H. van Dam Comments: 8 pages, LaTeX; Talk given by Jack Ng, in celebration of Paul Frampton's 60th birthday, at the Coral Gables Conference (in Fort Lauderdale, Florida on December 17, 2003). To appear in the Proceedings of the 2003 Coral Gables Conference
Spacetime foam, also known as quantum foam, has its origin in quantum fluctuations of spacetime. Arguably it is the source of the holographic principle, which severely limits how densely information can be packed in space. Its physics is also intimately linked to that of black holes and computation. In particular, the same underlying physics is shown to govern the computational power of black hole quantum computers.
Probing Planck-scale Physics with Extragalactic Sources?
http://arxiv.org/abs/astro-ph/0302372
Authors: Y. Jack Ng, W. A. Christiansen, H. van Dam (University of North Carolina) Comments: Minor changes; this version will appear in ApJ Letters Journal-ref: Astrophys.J. 591 (2003) L87-L90
At Planck-scale, spacetime is "foamy" due to quantum fluctuations predicted by quantum gravity. Here we consider the possibility of using spacetime foam-induced phase incoherence of light from distant galaxies and gamma-ray bursters to probe Planck-scale physics. In particular, we examine the cumulative effects of spacetime fluctuations over a huge distance. Our analysis shows that they are far below what is required in this approach to shed light on the foaminess of spacetime. |
