Cosmic Ring of Galaxies Defies Current Cosmology
Astronomers have identified a colossal, near-perfect ring of galaxies called The Big Ring, about 1.3 billion light-years across, plus the nearby Giant Arc in the same sky region. These structures exceed expected sizes and don’t fit standard formation scenarios, raising questions about the Cosmological Principle and potentially hinting at new physics (e.g., conformal cyclic cosmology or cosmic strings). The findings, led by Alexia Lopez of the University of Central Lancashire and published in the Journal of Cosmology and Astroparticle Physics, warrant more observations to determine their significance and frequency across the universe.
