The paper argues for a "metagalactic" gradient, or a change in galaxy density across the sky, based on galaxy counts from photographic plates, noting that some areas had twice as many galaxies as others. This was significant as it was one of the early studies to show the universe was not perfectly uniform on a large scale."--Google AI Overview.…
