A giant ring-like structure at 0.78<z<0.86 displayed by GRBs

Understand

According to the cosmological principle, Universal large-scale structure is homogeneous and isotropic.

• The observable Universe, however, shows complex structures even on very large scales.
• The recent discoveries of structures significantly exceeding the transition scale of 370 Mpc pose a challenge to the cosmological principle.
• We report here the discovery of the largest regular formation in the observable Universe; a ring with a diameter of 1720 Mpc, displayed by 9 gamma ray bursts (GRBs), exceeding by a factor of five the transition scale to the homogeneous and isotropic distribution.
