Coupling dark energy to dark matter inhomogeneities
We propose that dark energy in the form of a scalar field could effectively couple to dark matter inhomogeneities. Through this coupling energy could be transferred to/from the scalar field, which could possibly enter an accelerated regime. Though phenomenological, this scenario is interesting as it provides a natural trigger for the onset of the acceleration of the universe, since dark energy ...
متن کاملAlternatives to Dark Matter and Dark Energy
We review the underpinnings of the standard Newton-Einstein theory of gravity, and identifywhere it could possibly go wrong. In particular, we discuss the logical independence from eachother of the general covariance principle, the equivalence principle and the Einstein equations, anddiscuss how to constrain the matter energy-momentum tensor which serves as the source of gravity.<lb...
متن کاملDark Matter and Dark Energy
I briefly review our current understanding of dark matter and dark energy. The first part of this paper focusses on issues pertaining to dark matter including observational evidence for its existence, current constraints and the ‘abundance of substructure’ and ‘cuspy core’ issues which arise in CDM. I also briefly describe MOND. The second part of this review focusses on dark energy. In this pa...
متن کاملFrom Dark Energy & Dark Matter to Dark Metric
It is nowadays clear that General Relativity cannot be the definitive theory of Gravitation due to several shortcomings that come out both from theoretical and experimental viewpoints. At large scales (astrophysical and cosmological) the attempts to match it with the latest observational data lead to invoke Dark Energy and Dark Matter as the bulk components of the cosmic fluid. Since no final e...
