Abstract

Allowing for a nonvanishing spin tensor for cold dark matter (ωDM=0) has the consequence of giving rise to an effective FLRW dynamics with a small negative barotropic constant for an effective dark matter density (−1∕3<ωeff≤0). This turns out to solve the Hubble parameter tension in a straightforward way.
