Modified Einstein equations
Standard general relativity fails to take into account the changes in coordinates induced by the variation of metric in the Hilbert action principle. We propose to include such changes by introducing a fundamental compensating tensor field uniquely associated with any given coordinatization procedure.
متن کاملMaxwell's Equations and Einstein-Gravity in the Planck Aether Model of a Unified Field Theory
In the Planck aether substratum model it is assumed that space is densely filled with both positive and negative Planck masses described by a nonlinear nonrelativistic operator field equation. Without expenditure of energy this substratum can form a lattice of vortex rings, with the vortex core radius equal the Planck length. The vortex ring radius is determined by a universal minimum energy qu...
متن کاملGeneral Solutions for Field Equations in Einstein and High Dimensional Gravity
We prove that the Einstein equations can be solved in general form, for any spacetime dimension and various types of energy–momentum tensors following the anholonomic frame method for constructing exact solutions in gravity. In this work, we give proofs and extend to higher dimensions the results for four and five dimensional spacetimes provided in arXiv: 0909.3949 [gr-qc], version 1.
متن کاملSymmetric Vacuum Einstein Field Equations
According to Birkhoff’s theorem the only spherically symmetric solution of the vacuum Einstein field equations is the Schwarzschild solution. Inspite of imposing asymptotically flatness and staticness as initial conditions we obtain that these equations have general solutions with the Schwarzschild metric as merely a special and simplest form of them. It is possible to have perfect and smooth m...
متن کاملRelation Between Einstein And Quantum Field Equations
We show that there exists a choice of scalar field modes, such that the evolution of the quantum field in the zero-mass and large-mass limits is consistent with the Einstein equations for the background geometry. This choice of modes is also consistent with zero production of these scalar particles and thus corresponds to a preferred vacuum state preserved by the evolution. In the zero-mass lim...
