A massive ring of galaxies could lead to new physics. Here’s how

An intergalactic ring-shaped superstructure of galaxies and galaxy clusters has been discovered – so large that it defies explanation. This structure lives so deep in the universe that we see it as it was about 9.2 billion years ago.

The massive superstructure, nicknamed the “Big Ring,” spans 1.3 billion light-years and has a circumference of about 4 billion light-years. It is also close to another massive superstructure, which is…Giant arc in the sky“, which is actually larger, at 3.3 billion light-years in diameter. The giant arc is located at a similar distance to us in the constellation Boötes, the Shepherd. Unfortunately, these superstructures are too faint to be seen in a backyard telescope.
