Astronomers have discovered a cosmic megastructure
Scientists have recently made a groundbreaking discovery in space, uncovering a massive ring-shaped structure that challenges our current understanding of the universe. Known as the Big Ring, this cosmic megastructure has a diameter of approximately 1.3 billion light-years, making it one of the largest structures ever observed. When viewed from Earth, the Big Ring appears to be about the size of 15 moons in the night sky.
Until now, it has been widely believed that the universe is homogeneous on a large scale, meaning it looks the same in all directions. However, the discovery of the Big Ring, located more than nine billion light-years away from Earth, contradicts this long-standing belief. Comprised of galaxies and galaxy clusters, this structure is the second of its kind identified by British PhD student Alexia Lopez. Three years ago, Lopez also discovered the Giant Arc, a structure spanning 3.3 billion light-years.
The existence of such massive structures challenges current cosmological theories, which had not predicted structures of this scale. Lopez’s discoveries highlight the need to reassess our understanding of the universe, suggesting that our current models may be incomplete or even require a completely new theorem of cosmology. Lopez’s accidental discoveries have astounded her, as she presented her findings at the American Astronomical Society’s meeting in New Orleans. Both the Giant Arc and the Big Ring surpass expectations, with the Giant Arc being almost three times bigger and the Big Ring’s circumference comparable to the Giant Arc’s length.
The significance of these discoveries cannot be overstated, as they represent major milestones in scientific understanding. With advancements in technology and increasing expertise in the field, scientists continue to push the boundaries of knowledge and make fascinating revelations about the universe and its complexities.
