Dear Kent Benjamin Robertson,
All the physics you quote is several years old. There is a revolution going on in physics right now where string theory is being replaced by loop quantum gravity and process physics, although there is some evidence that LQG can derive string theory. It already can derive quantum mechanics. It derives what you say about Planck. It also derives area, and volume, and the big bang, not capitalized here as it did not start at a point.
So I will give you all the relevant recent publications below. The big names are Rovelli, Smolin, Theiman, Bojowald. But Bojowald has done the best recent work on cosmology. Then I will give you the work of Cahill which I believe is the phenomonology of LQG, even though the LQG people do not realize it yet. Then I will give you selections from others.
Happy readings,
J Rawson

Loop Quantum Cosmology: Recent Progress
Authors: Martin Bojowald
Comments: 17 pages, 2 figures, Plenary talk at ICGC 04, Cochin, India
Report-no: AEI-2004-017
Aspects of the full theory of loop quantum gravity can be studied in a simpler context by reducing to symmetric models like cosmological ones. This leads to several applications where loop effects play a significant role when one is sensitive to the quantum regime. As a consequence, the structure of and the approach to classical singularities are very different from general relativity: The quantum theory is free of singularities, and there are new phenomenological scenarios for the evolution of the very early universe including inflation. We give an overview of the main effects, focussing on recent results obtained by several different groups.

Loop Quantum Cosmology and Boundary Proposals

For many years, the most active area of quantum cosmology has been the issue of choosing boundary conditions for the wave function of a universe. Recently, loop quantum cosmology, which is obtained from loop quantum gravity, has shed new light on this question. In this case, boundary conditions are not chosen by hand with some particular physical intuition in mind, but they are part of the dynamical law. It is then natural to ask if there are any relations between these boundary conditions and the ones provided before. After discussing the technical foundation of loop quantum cosmology which leads to crucial differences to the Wheeler-DeWitt quantization, we compare the dynamical initial conditions of loop quantum cosmology with the tunneling and the no-boundary proposal and explain why they are closer to the no-boundary condition. We end with a discussion of recent developments and several open problems of loop quantum cosmology.

Homogeneous Loop Quantum Cosmology: The Role of the Spin Connection
Authors: Martin Bojowald, Ghanashyam Date, Kevin Vandersloot

Homogeneous cosmological models with non-vanishing intrinsic curvature require a special treatment when they are quantized with loop quantum cosmological methods. Guidance from the full theory which is lost in this context can be replaced by two criteria for an acceptable quantization, admissibility of a continuum approximation and local stability. A quantization of the corresponding Hamiltonian constraints is presented and shown to lead to a locally stable, non-singular evolution compatible with almost classical behavior at large volume. As an application, the Bianchi IX model and its modified behavior close to its classical singularity is explored.

Process Physics
Associate Professor Reg Cahill

Kirsty Kitto
A new paradigm for the modelling of reality is currently being developed called Process Physics. In Process Physics we start from the premise that the limits to logic, which are implied by Gödel's incompleteness theorems, mean that any attempt to model reality via a formal system is doomed to failure. Instead of formal systems we use a process system, which uses the notions of self-referential noise and self-organised criticality to create a new type of information-theoretic system that is realising both the current formal physical modelling of reality but is also exhibiting features such as the direction of time, the present moment effect and quantum state entanglement (including EPR effects, nonlocality and contextuality), as well as the more familiar formalisms of Relativity and Quantum Mechanics. In particular a theory of Quantum Gravity has already emerged.
In short, rather than the static 4-dimensional modelling of present day (non-process) physics, Process Physics is providing a dynamic model where space and matter are seen to emerge from a fundamentally random but self-organising system. The key insight is that to adequately model reality we must move on from the traditional non-process syntactical information modelling to a process semantic information modelling; such information is `internally meaningful'.

Quantum-Foam In-Flow Theory of Gravity and the Global Positioning System (GPS)
Abstract: It is shown that a new quantum-foam in-flow theory of gravity is mathematically equivalent to the General Relativity theory of gravity for the operation of the Global Positioning System (GPS). The differences between the two theories become experimentally evident in other situations such as in the so-called `dark matter' effect, in the observation of absolute motion and ipso facto in the observation of the in-flow motion into the Sun, and in the observation of a new class of gravitational waves, effects which are present in existing experimental observations, but are not within General Relativity. This new theory of gravity arises within the information-theoretic Process Physics.
Quantum-Foam, Gravity and Gravitational Waves
Abstract: It is shown that both the Newtonian and General Relativity theories for gravity may be re-formulated as in-flow dynamics in which a substratum is effectively absorbed by matter, with the gravitational force determined by inhomogeneities of that flow. Analysis herein of the 1925-26 Dayton Miller interferometer data reveals such a gravitational in-flow of space past the Earth into the Sun. This data and that from the 1991 Roland DeWitte coaxial cable experiment also suggests that the in-flow is turbulent, which amounts to the observation of a gravitational wave phenomena. A generalisation of the in-flow formalisms is proposed which passes all the tests that General Relativity passed, but as well the new theory suggests that the so-called spiral galaxy rotation-velocity anomaly may be explained without the need of `dark matter'. As well analysis of data from the Michelson and Morley, Miller, Illingworth, Jaseja et al, Torr and Kolen, and DeWitte experiments reveal motion relative to the substratum. Special relativity effects are caused by motion relative to the substratum. This implies that a new ontology underlies the spacetime formalism.
Gravity as Quantum Foam In-Flow
Abstract: The new information-theoretic Process Physics provides an explanation of space as a quantum foam system in which gravity is an inhomogeneous flow of the quantum foam into matter. The older Newtonian and General Relativity theories for gravity are analysed. It is shown that Newtonian gravity may be written in the form of an in-flow. General Relativity is also analysed as an in-flow, for those cases where it has been tested. An analysis of various experimental data demonstrates that absolute motion relative to space has been observed by Michelson and Morley, Miller, Illingworth, Jaseja et al, Torr and Kolen, and by DeWitte. The Dayton Miller and Roland DeWitte data also reveal the in-flow of space into matter which manifests as gravity. The experimental data suggests that the in-flow is turbulent, which amounts to the observation of a gravitational wave phenomena. A new in-flow theory of gravity is proposed which passes all the tests that General Relativity was claimed to have passed, but as well the new theory suggests that the so-called spiral galaxy rotation-velocity anomaly may be explained without the need of `dark matter'. Various other gravitational anomalies also appear to be explainable. Newtonian gravity appears to be strictly valid only outside of spherically symmetric matter systems.
Absolute Motion and Gravitational Effects
Abstract: The new Process Physics provides a new explanation of space as a quantum foam system in which gravity is an inhomogeneous flow of the quantum foam into matter. An analysis of various experiments demonstrates that absolute motion relative to space has been observed experimentally by Michelson and Morley, Miller, Illingworth, Jaseja et al, Torr and Kolen, and by DeWitte. The Dayton Miller and Roland DeWitte data also reveal the in-flow of space into matter which manifests as gravity. The in-flow also manifests turbulence and the experimental data confirms this as well, which amounts to the observation of a gravitational wave phenomena. The Einstein assumptions leading to the Special and General Theory of Relativity are shown to be falsified by the extensive experimental data. Contrary to the Einstein assumptions absolute motion is consistent with relativistic effects, which are caused by actual dynamical effects of absolute motion through the quantum foam, so that it is Lorentzian relativity that is seen to be essentially correct.
Process Physics: From Information Theory to Quantum Space and Matter
Abstract: This is a review of the new information-theoretic Process Physics. The fundamental assumption is that reality is to be modelled as self-organising semantic or relational information using a self-referentially limited neural network model, where the information-theoretic limitations are implemented via self-referential noise. This modelling was motivated by the discovery that such stochastic neural networks are foundational to known quantum field theories. In Process Physics time is a distinct non-geometric process while space and quantum physics are emergent and unified. 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 are the emergence of quantum field theory with 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, black holes and event horizons, and the emergence of classicality. The unification of the quantum foam structure of space with the quantum nature of matter amounts to the discovery of quantum gravity. Gravity is essentially an in-flow effect associated with the loss of information. A new theory of gravity for the classical limit is proposed, and shown to pass the key tests. A detailed analysis of various experiments demonstrates that absolute motion with respect to this space of quantum foam has been observed experimentally by Michelson and Morley, Miller, Illingworth, DeWitte and others. The Dayton Miller and Roland DeWitte data also reveal the in-flow of space into matter which manifests as gravity. The in-flow also manifests turbulence and the experimental data confirms this as well, which amounts to the observation of a gravitational wave phenomena. The Einstein assumptions leading to the Special and General Theory of Relativity are shown to be falsified by the extensive experimental data. Contrary to the Einstein assumptions absolute motion is consistent with relativistic effects, which are caused by actual dynamical effects of absolute motion through the quantum foam, so that it is Lorentzian relativity that is seen to be essentially correct. Process Physics brings physics very much into accord with the general concepts of Process Philosophy. The success of this new physics has profound implications for our comprehension of reality.

Dynamical Hierarchies in Fundamental Physics
Abstract: A new process orientated physics is being developed at Flinders University. These ideas were initially motivated by deep unsolved problems in fundamental physics, such as the difficulty of quantizing gravity, the missing arrow of time, the question of how to interpret quantum mechanics, and perhaps most importantly, a problem with the very methodology of our fundamental descriptions of the Universe. A proposed solution to these problems, Process Physics, has led to what can be viewed as a hierarchical model of reality featuring a Universe that exhibits behaviour very reminiscent of living systems.

Absolute Motion and Quantum Gravity
This paper has been superceded by the new analysis in the paper Process Physics: From Information Theory to Quantum Space and Matter. The understanding of the galactic in-flow effect was not immediate: In Michelson-Morley Experiments Revisted and the Cosmic Background Radiation Preferred Frame the direction was not determined, though the speed was found to be comparable to the CMB determined speed. In Analysis of Data from a Quantum Gravity Experiment that the directions were very different was noted but not appreciated, and in fact thought to be due to experimental error. In the paper Absolute Motion and Quantum Gravity an analysis of some of the `smoother' Michelson-Morley data resulted in an incorrect direction. At that stage it was not understood that the data showed large fluctuations in the azimuth apparently caused by the turbulence. The issue is hopefully finally resolved.
Analysis of Data from a Quantum Gravity Experiment
Process physics gives a new account of how Michelson interferometers operate when in gas mode. In particular they can detect absolute motion through the quantum foam, as shown in the previous paper. Here this new physics is applied to the extensive data from gas-mode interferometer observations by Miller (1933). The speed of in-flow of the quantum foam towards the Sun is determined from Miller's data to be 47 +\- 6 km/s, compared to the theoretical value of 42 km/s. This observed in-flow is a signature of aquantum gravity effect in the new physics.
Michelson-Morley Experiments Revisted and the Cosmic Background Radiation Preferred Frame
The Michelson-Morley interferometer experiments were designed to measure the speed of the Earth through the aether. The results were always believed to have been null - no effect. This outcome formed the basis for Einstein's Special and General Relativity formalism. The new process physics shows that absolute motion, now understood to be relative to the quantum foam that is space, is observable, but only if the interferometer operates in gas mode. A re-analysis here shows that the results from the gas-mode interferometers were not null, but in fact large when re-analysed to take account of the effect of the air, or helium, in which the apparatus operated. The speed of absolute motion is comparable to that determined from the Cosmic Background Radiation anisotropy, but the direction is not revealed. So absolute motion is meaningful and measureable, thus refuting Einstein's assumption. This discovery shows that a major re-assessment of the interpretation of the Special and General Relativity formalism is called for, a task already provided by Process Physics. This new information-theoretic physics makes it clear that Michelson-Morley type experiments are detecting motion through the quantum foam, which is space. Hence we see direct evidence of quantum gravity effects, as predicted by Process Physics. (This version corrects an earlier version of this paper, at arXiv:physics/0205065.)

Discrete Space Time and Dark Energy

Subj-class: General Physics
In recent times, Discrete Space Time Architectures are being considered, in the context of Quantum Gravity, Quantum Super Strings, Dark Energy and so on. We show that such a scheme is intimately tied up with a varying $G$ cosmology, which again explains otherwise inexplicable observations like the anomalous accelerations of Pioneer space crafts as also considerations involving the Zero Point Field, Random Electrodynamics and the derivation of Quantum Mechanical effects therefrom as also intertial mass.

Comparison of area spectra in loop quantum gravity
Authors: G. Gour, V. Suneeta
Comments: 7 pages, Revtex 4
We compare two area spectra proposed in loop quantum gravity in different approaches to compute the entropy of the Schwarzschild black hole. We describe the black hole in general microcanonical and canonical area ensembles for these spectra. For one of these spectra - the equally-spaced spectrum - we show in light of a proposed connection of the black hole area spectrum to the quasinormal mode spectrum that this spectrum is completely consistent with this connection. This follows {\em without} requiring a change in the gauge group of the spin degrees of freedom in this formalism from SU(2) to SO(3).

Propagation of Light in Doubly Special Relativity
Authors: Sung Ku Kim, Sun Myong Kim, Chaiho Rim, Jae Hyung Yee
Comments: 11 pages, LaTeX
In an attempt to clarify what is the velocity of a particle in doubly special relativity, we solve the Maxwell's equation invariant under the position space nonlinear Lorentz transformation proposed by Kimberly, Magueijo and Medeiros. It is shown that only the amplitude of the Maxwell wave, not the phase, is affected by the nonlinearity of the transformation. Thus, although the Maxwell wave appears to have infinitely large energy near the Planck time, the wave velocity is the same as the conventional light velocity. Surprisingly, the velocity of the Maxwell wave is not the same as the maximum signal velocity determined by the null geodesic condition, which is infinitely large near the Planck time and monotonically decreases in time to the conventional light velocity when time approaches infinity.
