This galaxy pair has long been a cornerstone for those who are critical of the view that the universe is expanding, and advocates for non-standard cosmology such as Halton Arp, Fred Hoyle, and others.[like whom?][5][6] This is due to the position of two quasars, one at each edge of the filament connecting the two galaxies, with much more redshift than either galaxy.
