Earth than previously believed, challenging fundamental assumptions about how the universe is structured and evolves.
This cosmic structure was first observed in 2014 — a dense galaxy forming a filament of a supercluster.

A new study now extends the researchers' previous work, but with a wider GRB sample. Hakkila and Zsolt Bagoly, authors of the study, have refined the measurements. They detected a number of relatively nearby GRBs in their sample. The evidence also shows the Great Wall is larger and wider than previously predicted.

Gamma-Ray Bursts Expose Structure Too Large for Current Models 201i3u

According to a Space.com neutron stars — produce powerful jets that can be spotted over cosmological distances. Hakkila told the publication that GRBs act as another bright beacon for identifying galaxies, even those too faint to see directly. Because of their brightness, scientists can follow matter throughout the universe more distinctly than ever.

The Great Wall, over 10 billion light-years long, challenges the cosmological principle of uniform universe appearance. Its massive size indicates gaps in current theories and implies that the universe's formation time was insufficient for such massive structures.

ESA mission THESEUS — the Transient High Energy Sources and Early Universe Surveyor — as the next major leap.

The mission aims to dramatically expand the catalogue of known GRBs, particularly at extreme distances. “It could finally provide the observational leverage needed to map the Hercules–Corona Borealis Great Wall to its full extent,” Hakkila told Space.com, emphasising its role in refining our understanding of the universe's large-scale structure.
