PHOENIX — An abnormally huge cosmic structure has put a ring on it — and that bling might threaten a fundamental assumption of cosmology.
A ring of dense matter spans more than 3.3 billion light-years, cosmologist Alexia Lopez reported January 6 at a meeting of the American Astronomical Society. If real, the structure could pose a problem for the cosmological principle, which holds that the universe looks the same in all directions on large scales.
