Tiagong, there is a ultra ultra large Ring structure in space that defy all human science model de woh

A colossal structure in the distant Universe is defying our understanding of how the Universe evolved.

In light that has traveled for 6.9 billion years to reach us, astronomers have found a giant, almost perfect ring of galaxies, some 1.3 billion light-years in diameter. It doesn't match any known structure or formation mechanism.
 
It's the second giant structure discovered by Lopez and her colleagues. The first, called the Giant Arc, is actually in the same part of the sky, at the same distance away. When the arc's discovery was announced in 2021, it puzzled astronomers. The Big Ring only deepens the mystery.
 
Neither of these two ultra-large structures is easy to explain in our current understanding of the universe," Lopez says. "And their ultra-large sizes, distinctive shapes, and cosmological proximity must surely be telling us something important – but what exactly?"


The most immediate link seems to be with something called a Baryon Acoustic Oscillation (BAO). These are giant, circular arrangements of galaxies found all throughout space.

They're actually spheres, the fossils of acoustic waves that propagated through the early Universe, and then froze when space became so diffuse acoustic waves could no longer travel.
 
At the moment, nobody knows for sure what the Big Ring and the Giant Arc signify. They could just be chance arrangements of galaxies twirling across the sky, although the likelihood of that seems pretty small.


The best hope would be to find more such arrangements of galaxies, scattered throughout the Universe, hiding in plain sight.


"From current cosmological theories we didn't think structures on this scale were possible," Lopez says. "We could expect maybe one exceedingly large structure in all our observable universe. Yet, the Big Ring and the Giant Arc are two huge structures and are even cosmological neighbors, which is extraordinarily fascinating."

The research was presented at the 243rd meeting of the American Astronomical Society.
