## Quantum Gravity and String Theory   ## Beautiful Universe: Towards Reconstructing Physics From New First Principles

A proposal to reconstruct physics from simple physically realistic first principles is outlined using a Beautiful Universe model. Just one type of �building block� is used: a spherically-symmetrical charged node spinning with angular momentum in units of Planck�s constant (h). Rotating nodes magnetize and self-assemble as a regular face-centered cubic attice to form the vacuum, radiation and matter. Three space and one time dimension are derived from the lattice and node interactions. Mutual repulsion between nodes with their like poles aligned accounts both for the accelerating expansion of the universe (dark energy) and the vacuum pressure on matter (dark matter). A spinning node transfers its angular momentum to adjacent nodes by rotating on an orthogonal axis, thus creating an electromagnetic field with forward momentum. The spin rate of the node receiving the momentum, its �density� determines the variable rate cv at which it receives the radiation. In a vacuum cv is the maximum, c0 the velocity of light. Two or more adjacent nodes locked together through a tensegrity of attractive (+ -) and repulsive electrostatic forces form as matter. The surrounding nodes twist and orient their axes to form magnetic, gravitational or electrostatic fields. The inverse-square law and E=mc02 are derived from the resulting geometry. Motion of matter is a self-convolution of an energy pattern in the lattice. This links Newtonian force and mass directly to domino-like transfer of momentum between nodes, in units of h, whereby a collision causes a relativistic contraction of an object�s length. Doppler shifts in the signals used by an outside observer to measure the moving object causes a further contraction in the estimated length, equivalent to time dilation. The two effects explain a result of Special relativity in classical terms. Using the Hamiltonian Analogy and the idea of a node index of refraction n=c0/cv General Relativity is reduced to the dynamics of energy transport along streamlines made up of nodes of different rotation. Variable velocity along curved streamlines is acceleration and hence gravity. Quantum probability is derived from the electric field of a dipole wave in the lattice where Heisenberg�s uncertainty relations emerge naturally from the resulting geometry. Cosmological inflation, but not a Big-Bang singularity would result from initial conditions of nodes in their closest proximity to each other. The outline of a discrete calculus needed to describe the model�s interactions is presented. Some experiments are proposed to test various aspects of the model.
