According to astronomer Greg Aldering, the scale of the void is such that "If the Milky Way had been in the center of the Boötes void, we wouldn't have known there were other galaxies until the 1960s."
Tähtitieteilijä Greg Alderingin mukaan tyhjiön mittakaava on sellainen, että "jos Linnunrata olisi Karhunvartijan tyhjiön keskellä, emme olisi saaneet tietää muiden galaksien olemassaolosta ennen 1960-lukua."
