The so-called Big Ring has a diameter of about 1.3bn light years, making it among the largest structures ever observed. At more than 9bn light years from Earth, it is too faint to see directly, but its diameter on the night sky would be equivalent to 15 full moons.

This is important because it contradicts the so-called “cosmological principle” that everything in the universe is basically evenly distributed.
Just thinking about it, though, it makes little sense to assume that galaxies are all evenly spaced. Assuming the Big Bang was a single point should not imply even spacing of anything.
FWIW the “Big Ring” is evidently more a corkscrew shape, directly aimed at us. Evidence of “cosmic strings”? Maybe.
This is not as interesting as technology that will allow us to build hotels and colonies at LaGrange points or communities on Mars, but it’s still interesting. Sorta. Maybe?
