A Map to Unified Grand Model for Space Time, Particles, Fields and Universe Builded on a Trial Mathematical Physics Interpretation of the Holy Quran Creation Story

Authors: Maher Ahmed
Comments: 21 pages

Since early 1980 there is no new discoveries for the basic laws of physics[1], the main problem behind that is the missing of a complete physical description for our universe physics. The concepts of space time, particles (mass), fields, and energy have a big ambiguity in our deep understanding of physics. One of reasons for that is the limitation of our experimental technology in high energy accelerators, and in cosmological observations. In this research the author follows the creative thinking rules which discovered in the field of human psychology studies[2{4] for solving difficult problems through human specie history. The main idea in creative thinking is to borrow ideas and concepts from fields away from the problems own field, those new ideas and concepts are brought to the field of the problems to help human to go inside the problems and get the solution[5]

Interrelatedness of Space and Time

Authors: Amrit S. Sorli
Comments: 4 pages

Experimental data confirm material change i.e. motion run in space. There is no experimental evidence time being part of the space. Time is what we measure with clocks. With clocks we measure numerical order (see paper for full abstract)

Comments on "The Entropic Accelerating Hologram Universe"

Authors: Jack Sarfatti
Comments: 5 pages

The accelerated expansion rate is no longer surprising. It is the inevitable consequence of the holographic information storage on the surface screen of the universe.

The "Hourglass" or "Grail" Diagrams

Authors: John A. Gowan
Comments: 5 pages

A General Systems model in the form of an hourglass is used to illustrate the relationships among the four forces of physics, space, time, and nuclear and elementary particles.

Generalized Gravity in Clifford Spaces, Vacuum Energy and Grand Unification

Authors: Carlos Castro
Comments: 21 pages, submitted to the Int. J. Mod. Phys. A.

Polyvector-valued gauge field theories in Clifford spaces are used to construct a novel Cl(3, 2) gauge theory of gravity that furnishes modified curvature and torsion tensors leading to important modifications of the standard gravitational action with a cosmological constant. Vacuum solutions exist which allow a cancellation of the contributions of a very large cosmological constant term and the extra terms present in the modified field equations. Generalized gravitational actions in Clifford-spaces are provided and some of their physical implications are discussed. It is shown how the 16 fermions and their masses in each family can be accommodated within a Cl(4) gauge field theory. In particular, the Higgs fields admit a natural Clifford-space interpretation that differs from the one in the Chamseddine-Connes spectral action model of Noncommutative geometry. We finalize with a discussion on the relationship with the Pati-Salam color-flavor model group SU(4)C x SU(4)F and its symmetry breaking patterns. An Appendix is included with useful Clifford algebraic relations.

Supplying Conditions for Having up to 1000 Degress of Freedom in the Onset of Inflation, Instead of 2 to 3 Degrees of Freedom, Today, in Space-Time.

Authors: Andrew Beckwith
Comments: 7 Pages. Fixed several typos. Also re configured to be sent into a journal for analysis

The following document attempts to answer the role additional degrees of freedom have as to initial inflationary cosmology. I.e. the idea is to cut down on the number of independent variables to get as simple an emergent space time structure of entropy and its generation as possible. One parameter being initial degrees of freedom, the second the minimum allowed grid size in space time, and the final parameter being emergent space time temperature. In order to initiate this inquiry, a comparison is made to two representations of a scale evolutionary Friedman equation, with one of the equations based upon LQG, and another involving an initial Hubble expansion parameter with initial temperature TPlanck ~ 10^19 GeV used as an input into T4 times N(T). Initial assumptions as to the number of degrees of freedom has for TPlanck ~ 10^19 GeV a maximum value of N(T) ~ 103 . Making that upper end approximation for the value of permissible degrees of freedom is dependent upon a minimum grid size length as of about lPlanck ~ 10^-33 centimeters. Should the minimum uncertainty grid size for space time be higher than lPlanck ~ 10^-33 centimeters, then top value degrees of freedom of phase space as given by a value N(T) ~ 10^3 drops. In addition, the issue of bits, i.e. information is shown to not only have temperature dependence, but to be affected by minimum 'grid size' as well. A bifurcation diagram argument involving Hemoltz free energy as a 'driver' to push through a transition from a prior universe to the present universe, with classical physics behavior down to a grid size of lPlanck ~ 10^-33 centimeters ( i.e. start of quantum gravity effects) is employed to invoke use of classical physics down to lPlanck ~ 10^-33 centimeters. Subsequent chaotic dynamics during the expansion phase driven by Helmholtz free energy leads to up to N(T) ~ 103 degrees of freedom at the start of the inflationary regime. The possibility this semi classical argument for increase of the degrees of freedom up to N(T) ~ 10^3 is tied in with the possible emergence of space time E8 embedding is included as a speculative bonus. This is akin to Bogolyubov "spontaneous" particle creation arguments outlined in the article.
