There are no apparent inconsistencies between the existence of the Boötes void and the Lambda-CDM model of cosmological evolution.[8] It has been theorized that the Boötes void was formed from the merger of smaller voids, much like the way in which soap bubbles coalesce to form larger bubbles. This would account for the small number of galaxies that populate a roughly tube-shaped region running through the middle of the void.[2]
