Graphic solution of R-W metric for the case of positive curvature and cosmic entire space and time

2011/9/26
The vivid image of R-W metric for the case of hypersphere is given; The hypersphere is proposed as the only model for the physical universe; The cosmic radius R(t) may be defined as a cosmic broad tim...
We consider inflation within the context of what is arguably the simplest non-metric extension of Einstein gravity. There non-metricity is described by a single graviscalar field with a non-minimal ki...
Dark matter from primordial metric fields and the term (grad g_{00})^2
Dark matter primordial metric fields
2011/9/27
It is a well-known truism, inspired on the general theory of relativity, that gravity gravitates. Here we suggest the possibility that dark matter may be caused by the gravitation of the metric. At fi...
Masking a singularity with k-essence fields in an emergent gravity metric
emergent gravity metric
2010/11/16
It is known that dynamical solutions of the k-essence equation of motion change the metric for
the perturbations around these solutions and the perturbations propagate in an emergent spacetime with m...
Expanding perfect fluid generalizations of the C-metric
C-metric perfect fluid gravitational fields
2010/3/18
We reexamine Petrov type D gravitational fields generated by a perfect fluid with spatially homogeneous energy density and in which the flow lines form a timelike non-shearing and non-rotating congrue...
The Robertson-Walker Metric in a Pseudo-Complex General Relativity
Walker metric energy-momentum
2010/3/18
We investigate the consequences of the pseudo-complex General Relativity within a pseudo-complexified Roberston-Walker metric. A contribution to the energy-momentum tensor arises, which corresponds to...
