An international team led by academics from the University of Central Lancashire (UCLan) has found the largest known structure in the universe – a large quasar group that challenges scientific understanding of our universe.
The Cosmological Principle is the assumption that the universe, when viewed at a sufficiently large scale, looks the same no matter where you are observing it from.
Whole clusters of galaxies can be 2-3 Mpc across but LQGs [large quasar groups] can be 200 Mpc or more across. Although, based on the Cosmological Principle and the modern theory of cosmology, calculations suggest that astrophysicists should not be able to find a structure larger than 370 Mpc.
