In astrophysics/cosmology, the KBC void (KBC13) refers to a large neighbourhood of the Milky Way whose average matter density is considerably smaller than on average in the observable universe.
In the context of inhomogeneous cosmology, this means that the Hubble constant effectively observed inside the void appears larger than that given by the cosmological constant of a large-scale homogeneous FRW model. It has been suggested that this might explain away the need for the dark energy hypothesis, or at least help explain recent tensions in different measurements of the Hubble constant, but the issue remains debated (Wu-Huterer 17).
