Giant Arc of galaxies 3 billion light-years long may challenge standard model of cosmology

Amazing stuff! More and more recent observations are challenging the Big Bang theory!

In my opinion, the Big Bang theory is one of the most implausible major scientific theories that still survives to this day! I have previously speculated here that if there was indeed a Big Bang as they say, then the universe is perhaps only an aquarium built by God or by super intelligent beings.

"... If it is real, the Giant Arc would join a growing group of large-scale structures in the universe that, taken together, would break the standard model of cosmology. This model assumes that when you look at large enough volumes of space — above about 1 billion light-years — matter is distributed evenly. The Giant Arc appears about three times as long as that theoretical threshold. It joins other structures with similarly superlative names, like the Sloan Great Wall, the Giant Gamma-Ray Burst Ring and the Huge Large Quasar Group. ..."

Here is the entire abstract of this discovery:

"We present the discovery of the Giant Arc, a large-scale structure marked by MgII absorbers spanning approximately 1 Gpc in length and 100 Mpc in width (present epoch values), at a redshift of z ~ 0.8. The structure forms a highly symmetric arc in the plane of the sky, but shows more intricate structuring along the redshift axis, with a depth of ~ 340 Mpc. Two different statistical analyses show the Giant Arc to be significant at > 4 sigma. We discuss the implications for the Giant Arc in context with other known large structures for the fundamental assumption of homogeneity in cosmology."
