It has a diameter of 1.3 billion light-years and appears to be approximately 15 times the size of the Moon in the night sky as seen from Earth.

Astronomers have named it the Big Ring, and it is made up of galaxies and galaxy clusters.

They claim that it is so large that it defies our understanding of the universe.

It can’t be seen with the naked eye. It is extremely far, and locating all of the galaxies that make up the larger structure has required a significant amount of time and computational power.

The cosmological principle, one of astronomy’s guiding concepts, states that such enormous structures should not exist. This states that all matter is uniformly distributed throughout the universe.

Although stars, planets, and galaxies appear to be massive clumps of matter, they are small in comparison to the expanse of the universe, and the theory states that far larger patches of matter should not arise.

The Big Ring is not the first potential violation of the cosmological principle, implying that there is another, yet-to-be discovered, force at work.

According to Dr. Robert Massey, deputy director of the Royal Astronomical Society, evidence for a rethinking of what has long been a cornerstone of astronomy is growing.

“This is the seventh big structure revealed in the universe that challenges the notion that the cosmos is smooth on the largest scales. If these structures exist, it is certainly food for thought for cosmologists and the conventional view of how the universe has evolved over time,” he said.
