Is Reality Digital Or Analog? Physics Is Undecided - A Beautiful Universe Theory's Answer.

Authors: Vladimir F. Tamari
Comments: 11 pages

In Section 1 the three words comprising the question "Is Reality Digital or Analog" <D/A?> are defined further. In Section 2 Key aspects of physics are probed using <D/A?> and contradictions pointed out. The incompatibility of an analog Gravity and an analog-digital Quantum Mechanics are traced back to Einstein's point-photon and his flexible spacetime. Without a unified theory it is fruitless to decide about the basic makeup of the universe. Space and Time, Electromagnetic Radiation, Matter and Gravity, and Quantum Mechanics in general are examined with <D/A?>. In Section 3 <D/A?> is answered within a new Beautiful Universe model ToE 'Theory of Everything' proposed from first principles. A universal lattice of identical spherically-symmetrical interacting dielectric nodes exchanging angular momentum through magnetic induction, in units of Planck's constant (h) is proposed. The 3 space dimensions and time, vacuum, matter, radiation, dark energy and dark matter are derived from the causal, local self-assembly and Hamiltonian evolution through interactions between neighboring nodes. Each node represents a miniature Bloch sphere, at a variable rate depending on node rates of rotation, and the orientation of their axis. The model explains matter as nested polyhedral patterns of nodes locked by tensegrity yet capable of soliton-like translation. Quantum effects are the result of the diffusion of momentum in a wave pattern through the lattice. Gravitational potential equals node rotation, but its force is due to the spring-like twisting geometry of the node axes in the regions of space between matter.

Quantum Gravity Based on Mach Principle and its Solar Application

Authors: Jin He
Comments: 21 pages

The starting point of quantum mechanics is the classical algebraic formula connecting energy to momentum: energy is proportional to the squared momentum. As a result, energy and momentum do not be treated equally. The wave equation of quantum mechanics (a differential equation) results from the replacement of the classical energy quantity with the derivative with time and the replacement of the momentum quantity with the derivative with space. Both replacements have a scale factor that is the Planck constant. Similar to the classical formula, the wave equation does not treat time and space equally, and the Planck constant is not canceled out from both sides of the equation. That is, Planck constant remains which describes the microscopic world. My theory of gravity is the local bending of background spacetime based on Mach principle which, as suggested by Einstein, is described by a classical form of second order treating time and space equally. Therefore, the Planck constant is completely canceled out in the wave equation. In other words, the quantization of gravity does not need the Planck constant. This is because gravity obeys Equivalence Principle. But I keep the scale factor which describes the hierarchical structure of local universe as suggested by Laurent Nottale.

A Clifford Cl(5,C) Unified Gauge Field Theory of Conformal Gravity, Maxwell and U(4) x U(4) Yang-Mills in 4D

Authors: Carlos Castro
Comments: 22 pages, submitted to Advances in Applied Clifford Algebras (AACA).

A Clifford Cl(5,C) Unified Gauge Field Theory of Conformal Gravity, Maxwell and U(4)xU(4) Yang-Mills in 4D is rigorously presented extending our results in prior work. The Cl(5,C) = Cl(4,C)⊕Cl(4,C) algebraic structure of the Conformal Gravity, Maxwell and U(4)xU(4) Yang-Mills unification program advanced in this work is that the group structure given by the direct products U(2, 2)xU(4)xU(4) = [SU(2, 2)]spacetimex [U(1) x U(4) x U(4)]internal is ultimately tied down to four-dimensions and does not violate the Coleman-Mandula theorem because the spacetime symmetries (conformal group SU(2, 2) in the absence of a mass gap, Poincare group when there is mass gap) do not mix with the internal symmetries. Similar considerations apply to the supersymmetric case when the symmetry group structure is given by the direct product of the superconformal group (in the absence of a mass gap) with an internal symmetry group so that the Haag-Lopuszanski-Sohnius theorem is not violated. A generalization of the de Sitter and Anti de Sitter gravitational theories based on the gauging of the Cl(4, 1,R),Cl(3, 2,R) algebras follows. We conclude with a few remarks about the complex extensions of the Metric Affine theories of Gravity (MAG) based on GL(4,C) xs C4, the realizations of twistors and the N = 1 superconformal su(2, 2|1) algebra purely in terms of Clifford algebras and their plausible role in Witten's formulation of perturbative N = 4 super Yang-Mills theory in terms of twistor-string variables.

Discrete Time and Kleinian Structures in Duality Between Spacetime and Particle Physics

Authors: Lawrence B. Crowell
Comments: 11 pages

The interplay between continuous and discrete structures results in a duality between the moduli space for black hole types and AdS7 spacetime. The 3 and 4 Q-bit structures of quantum black holes is equivalent to the conformal completion of AdS.

Quantum Gravity and Superconductivity II

Authors: Peter C. Chindove
Comments: 3 pages

In my first paper, Quantum Gravity and Superconductivity, I made two significant proposals. One, rather tongue in cheek, I proposed a method in which the extent to which an individual is deluded defines whether or not that individual is a crackpot. I termed this the Delusion Index. Two, I proposed the Painleve type III equation as the background for developing a quantum theory of magnetic induction and of gravity.
