The largest structure of the Universe, defined by Gamma-Ray Bursts

Understand

Research over the past three decades has revolutionized the field of cosmology while supporting the standard cosmological model.

• However, the cosmological principle of Universal homogeneity and isotropy has always been in question, since structures as large as the survey size have always been found as the survey size has increased.
• Until now, the largest known structure in our Universe is the Sloan Great Wall (SGW), which is more than 400 Mpc long and located approximately one billion light-years away.
• Here we report the discovery of a structure at least six times larger than the Sloan Great Wall that is suggested by the distribution of gamma-ray bursts (GRBs).
