[7][8] The Local Void appears to have significantly fewer galaxies than expected from standard cosmology.

[4] The size of the Local Void was calculated due to an isolated dwarf galaxy known as ESO 461-36 located inside it.

[4] Dark energy has been suggested as one alternative explanation for the speedy expulsion of the dwarf galaxy.

[3] An earlier "Hubble Bubble" model, based on measured velocities of Type 1a supernovae, proposed a relative void centred on the Milky Way.

[12] Several authors have shown that the local universe up to 300 Mpc from the Milky Way is less dense than surrounding areas – by 15–50%.
