A ring of galaxies in space that is so large it challenges our understanding of the universe has been discovered by a team of astronomers at a British university. The diameter of the big ring is 1.3 billion light years, making it 15 times the size of the Moon if we could see it in the night sky.
The discovery contradicts the cosmological principle, which states that entities of matter much larger than galaxies should not form in space. This is the seventh large structure found in the universe that goes against this principle.
According to Professor Robert Massey, Deputy Director of the Royal Astronomical Society of Great Britain, this may require reevaluation of one of the central principles of astronomy.
Lopez made the discovery with help from telescopes and computers and presented it at the 243rd Annual Meeting of American Astronomical Society held in early January in New Orleans. He is a PhD student in astronomy at UCLan, England. The structure spans over 1.3 billion light years and Lopez thinks that it could be remnants of early universe as he believes that these structures have another shape than what they appear to be from Earth’s perspective.
