Einstein universes stabilized | Erhard Scholz
; | Date: |
1 Oct 2007 | Abstract: | The hypothesis that gravitational self-binding energy may be the source for
the vacuum energy term of cosmology is studied in a Newtonian Ansatz. For
spherical spaces the attractive force of gravitation and the negative pressure
of the vacuum energy term form a self stabilizing system under very reasonable
restrictions for the parameters, among them a characteristic coefficient eta
of self energy. In the Weyl geometric approach to cosmological redshift,
Einstein-Weyl universes with observational restrictions of the curvature
parameters are dynamically stable, if eta is about 40 % smaller than in the
exact Newton Ansatz or if the space geometry is elliptical. | Source: | arXiv, 0710.0269 | Services: | Forum | Review | PDF | Favorites |
