"Unprecedented Discovery in Distant Space Challenges Cosmological Principles"
The discovery of a second ultra-large structure in the remote universe, known as the Big Ring, challenges basic assumptions about cosmology. This structure, located 9.2 billion light-years from Earth, has a diameter of about 1.3 billion light-years and a circumference of about four billion light-years. Its discovery, along with the previously found Giant Arc, raises questions about the standard understanding of the universe and the Cosmological Principle. Possible explanations include Baryonic Acoustic Oscillations, Conformal Cyclic Cosmology, or the effect of cosmic strings passing through.
