A group of galaxies in space has been discovered that challenges our understanding of the universe, according to astronomers at a British university. The diameter of the ring is 1.3 billion light years, which is 15 times the size of the Moon if we could see it in the night sky. This discovery contradicts one principle of cosmology, which states that all matter should be spread evenly throughout the universe.
The principle requires that entities of matter much larger than galaxies should not form in space. However, this discovery is already the seventh large structure found in the universe that contradicts this principle. Deputy Director of the Royal Astronomical Society of Great Britain Robert Massey says that this may require re-evaluation of this central principle of astronomy.
This structure was discovered by PhD student Alexia Lopez with the help of telescopes and computers and spans no less than 1.3 billion light years. Lopez also discovered another space superstructure called Giant Arc, although he believes it has a different shape than a ring in the sky. He wonders on BBC’s website how such a mechanism could produce these structures, making him believe that these structures may be remnants from the early universe.
The Big Ring and Giant Arc are located more than nine billion light-years away from Earth, and Lopez presented his discovery at the 243rd Annual Meeting of the American Astronomical Society (AAS) held in New Orleans earlier this year. This discovery challenges our understanding of how galaxies are formed and distributed in space, and it opens up new possibilities for further research into the mysteries of the universe.
