Can the Hubble tension be resolved by bulk viscosity?
Ben David Normann, Iver Håkon Brevik
Abstract
We show that the cosmic bulk viscosity estimated in our previous works is sufficient to bridge the [Formula: see text] value inferred from observations of the early universe with the value inferred from the local (late) universe.
