Title: Symmetry arguments solving the problems of Dark Matter and Dark Energy
Abstract: We develop some symmetry arguments solving the problems of Dark Matter and Dark energy. From this perspective, Dark Energy is vacuum energy and symmetry constraints suppress naturally the UV modes when we calculate the vacuum energy density. In this way we derive theoretically the appropriate value matching with the observations. On the other hand, we derive a new vacuum solution able to reproduce the effects normally attributed to Dark Matter. The new vacuum solution is able to reproduce the Tully-Fisher law and the scales where the Dark Matter effects appear. In this way, Dark Matter is not necessary for reproducing the observed effects at the galactic scales.
