Is Bootes Void a Black Hole?

Previously, the black hole accretion in centers of void galaxies had been studied in only a handful of objects contained in only one void region, the Bootes Void.

Why is Boötes void empty?

One theory, which recent evidence may back up, is that it formed when two or more ordinary voids collided. Boötes is not quite empty: it turns out to contain a sprinkling of galaxies arranged in a tubular shape. This could be the remains of the shared edge of two smaller voids before they combined.

Is the Milky Way in the Boötes void?

Boötes void is the largest known void scientists have found. 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."
