Phenomenological covariant approach to gravity
Abstract
We covariantly modify the EinsteinHilbert action such that the modified action perturbatively resolves the anomalous rotational velocity curve of the spiral galaxies and gives rise to the TullyFisher relation, and dynamically generates the cosmological constant. This modification requires introducing a single new universal parameter. It requires inclusion of neither dark matter nor dark energy.
