Not to be confused with Local Hole.
The Local Void is a vast, empty region of space, lying adjacent to the Local Group.[3][4] Discovered by Brent Tully and Rick Fisher in 1987,[5] the Local Void is now known to be composed of three separate sectors, separated by bridges of "wispy filaments".[4] The precise extent of the void is unknown, but it is at least 45 Mpc (150 million light-years) across,[6] and possibly 150 to 300 Mpc.[7][8] The Local Void appears to have significantly fewer galaxies than expected from standard cosmology.[9]
