Late time acceleration of our Universe caused by the absorption of baby universes

Abstract

If our Universe is allowed to absorb baby universes, one obtains a modified Friedmann equation that can explain the late time acceleration of our Universe and there is no need for a cosmological constant. In addition the modified Friedmann equation favors the value of the Hubble constant obtained by local measurements.
