Description
A metric extension of gravity based on the Tully-Fisher law is
presented. It will be shown that the Tully-Fisher law extends from the
dynamics of globular clusters up to the dynamics of groups of galaxies
and how it can be consider as a modified version of Kepler's third law.
With it, it will be shown how at second perturbation order lensing can
be fully understood and that the corresponding PPN gamma parameter is
required to be close to one. I will show how to construct a relativistic
metric extension of gravity using this observational facts and briefly
mention its potential for understanding the dynamics of clusters of
galaxies and of the expanding universe without the need to introduce
any dark matter/energy entities for its description.
