Can the External Directed Edges of a Complete Graph Form a Radially Symmetric Field at Long Distance?

Authors: S. Halayka
Comments: 7 Pages. Added reference McDonald JR, Miller WA. Coupling Non-Gravitational Fields with Simplicial Spacetimes

Using a numerical method, the external directed edges of a complete graph are tested for their level of fitness in terms of how well they form a radially symmetric field at long distance (e.g., a test for the inverse square law in 3D space). It is found that the external directed edges of a complete graph can very nearly form a radially symmetric field at long distance if the number of graph vertices is great enough.

Theory of First Force

Authors: Willi Penker
Comments: 3 pages

The effects of forces are well known; however, the basic mechanisms of how forces work and are transmitted remain unexplained. This essay is meant to determine these basic mechanisms.

To Demonstrate That Gravity Is Action-at-a-distance

Authors: Chun-Xuan Jiang
Comments: 14 pages

In this paper we explain the behavior of the entire universe from the smallest to the largest scales. We found the only tachyonic string theory (other string theories all are guesses), find an equation that changed the universe: F-bar = -mc2/R, establish the expansion theory of the universe without dark matter and dark energy, and prove that the principle of equivalence is nonexistent. We demonstrate that gravity is action-at-a-distance and that a gravitational wave is unobservable.We suggest a new universe model.

Objections to Quantum Gravity Theories based on Causal Dynamical Triangulation

Authors: Ervin Goldfain
Comments: 2 pages, Letters submitted to the Editors of Classical and Quantum Gravity (v1) and Physics Review Letters (v2).

This memo is in regards to the recently published contribution by Ambjorn J. et al. "Planckian Birth of Quantum de Sitter Universe" PRL 100, 091304 (2008). The article claims that "causal dynamical triangulation" enables a consistent regularization of quantum gravity. A "quantum universe" emerging from a nonperturbative sum over geometries is alleged to recover "with high accuracy a fourdimensional de Sitter space-time". On closer examination, the approach is built on many objectionable premises

On Nonlinear Quantum Mechanics, Noncommutative Phase Spaces, Fractal-Scale Calculus and Vacuum Energy

Authors: Carlos Castro
Comments: 18 pages, has been submitted to Foundations of Physics

A novel (to our knowledge) Generalized Nonlinear Schrödinger equation based on the modifications of Nottale-Cresson's fractal-scale calculus and resulting from the noncommutativity of the phase space coordinates is explicitly derived. The modifications to the ground state energy of a harmonic oscillator yields the observed value of the vacuum energy density. In the concluding remarks we discuss how nonlinear and nonlocal QM wave equations arise naturally from this fractal-scale calculus formalism which may have a key role in the final formulation of Quantum Gravity.

Numerical Solution of Quantum Cosmological Model Simulating Boson and Fermion Creation

Authors: V. Christianto, Florentin Smarandache
Comments: 2 pages

A numerical solution of Wheeler-De Witt equation for a quantum cosmological model simulating boson and fermion creation in the early Universe evolution is presented. This solution is based on a Wheeler-DeWitt equation obtained by Krechet, Fil'chenkov, and Shikin, in the framework of quantum geometrodynamics for a Bianchi-I metric.
