In modern physical cosmology, the cosmological principle is the notion that the spatial distribution of matter in the universe is homogeneity (physics), homogeneous and Isotropy, isotropic when viewed on a large enough scale, since the forces ar ...
of local galactic flow. It is thought to be the composite contributions of the
Shapley Concentration and the
Great Attractor
The Great Attractor is a gravitational anomaly in intergalactic space and the apparent central gravitational point of the Laniakea Supercluster. The observed anomalies suggest a localized concentration of mass millions of times more massive than ...
