Darkness without dark matter and energy -- generalized unimodular gravity |
|
Abstract |
We suggest a Lorentz non-invariant generalization of the unimodular gravity theory, which is classically equivalent to general relativity with a locally inert (devoid of local degrees of freedom) perfect fluid having an equation of state with a constant parameter w. For the range of w near −1 this dark fluid can play the role of dark energy, while for w=0 this dark dust admits spatial inhomogeneities and can be interpreted as dark matter. |
