Attraction-repulsion coupled and energy conserved universe | | Ti-Pei Li
; | | Date: |
11 Oct 2011 | | Abstract: | The discovery of an accelerating cosmic expansion rate implies that, in
addition to the attractive gravity of matter, there exist in our universe some
other form of energy (dark energy or cosmological constant) producing a
repulsive force. The natural interpretation of dark energy is the vacuum
energy. However, the density of vacuum energy expected by the quantum field
theory is 120 orders of magnitude larger than what allowed by cosmological
observations, which is called the cosmological constant problem and remains one
of the most significant unsolved problems in fundamental physics. Here we show
that the huge discrepancy between theoretical expectation and observational
data can be resolved by assuming that our universe is an attraction-repulsion
coupled system with energy conservation, and that the pre-inflation vacuum is
in balance between attraction and repulsion (a flat Minkowski spacetime, not de
Sitter or anti de Sitter). The attraction-repulsion coupling picture can also
easily explain why both kinds of energy in our universe have similar magnitude
today, and avoid singularity problems in general relativity and cosmology. | | Source: | arXiv, 1110.2678 | | Services: | Forum | Review | PDF | Favorites | |
