Doubt, something unknown? Sure. Structure? Doubt.

“Structure” in this case means “big glob of galaxies slightly closer together than other globs”

In astronomical terms structure doesn’t mean a building of any kind.

It’s not a “new” discovery or even the “second”. I suggest they read the 2015 paper they are almost copying from.

Evidence suggests that this feature is the projection of a shell on to the plane of the sky. Voids and string-like formations are common outcomes of large-scale structure. However, these structures have maximum sizes of 150 Mpc, which are an order of magnitude smaller than the observed GRB ring diameter. Evidence in support of the shell interpretation requires that temporal information of the transient GRBs be included in the analysis. This ring-shaped feature is large enough to contradict the CP. The physical mechanism responsible for causing it is unknown.

Weird reporting like this is “new” GRB ring out of Swift and Sloan SDSS data.

Sloan Great Wall, which is around 1.5 billion light-years in length

South Pole Wall, which stretches 1.4 billion light-years across.

Hercules-Corona Borealis Great Wall, which is about 10 billion light-years wide

It is approximately 9.1 billion light years from Earth and about 5.6 billion light years across

New objects:

Big Ring in the Sky is 9.2 billion light-years from Earth. It has a diameter of about 1.3 billion light-years

Giant Arc in the Sky which is 3.3 billion light-years across,
