The Large Ring PhD student Alexia Lopez was analyzing data from the Sloan Digital Sky Survey to investigate the remote regions of the universe. Alexia Lopez observed a colossal formation of Galactic clusters, referred to as the big ring, situated at a distance of 9.2 billion light years from our location. The object’s dimensions are incredibly large, measuring a diameter of 1.3 billion light years and a circumference of 4 billion light years. Although the big ring may be the largest structure in the observable universe, its existence poses a challenge to well-established cosmological principles. The ring is causing disruptions in the fundamental principles of astrophysics.
Know about the Big Bang
We need to travel back in time to the Big Bang, and I believe that during the first few hundred years after the Big Bang, an ocean of dense plasma filled the universe as waves rippled through it. It created peaks and valleys, which are known as barriers to acoustic oscillation, and believed that the places where matter bunched up on these primordial waves were what led to the distribution of matter that we see throughout the universe.
Discovery of the Giant Arc
Today, the problem lies in the analysis of the Big Bang and current models of BAO, which suggest that the upper limit for cosmic structure should be approximately 1.2 billion light years. The length of the cosmic structure initially seemed impressive, but as we began to discover objects larger than this upper limit, like the big ring, the odds became even more improbable. This is because the big ring is adjacent to another limit breaker. The same PhD student, Alexia Lopez, also made the discovery of the giant Arc in the Sky in 2021. The giant Arc, which spans 3.3 billion light years, is considered by some to be larger than the big ring.
2024’s Big Ring
Our Milky Way resides in the Lancia supercluster, which is only about 520 million light years in diameter, meaning that despite containing an estimated 100,000 galaxies, The massive ring completely dwarfs it, and the colossal arc is so vast that it would be visible to human eyes in the night sky. It would take up the space of 20 full moons lined up side by side, and overall, it takes up about 1/5 of the radius of the entire visible universe. So with the addition of 2024’s Big Ring, we now have two super massive structures whose origins defy explanation and whose surprising proximity raises further questions. As Lopez herself puts it, the big ring and the giant Arc both individually and together give us a big cosmological mystery.
