The news about the Huge LQG is still posted on Reuters/News Daily as of this writing and may still be found on Science Daily and even in the Wikipedia. The discoverers posted their findings in the Arxiv paper "A structure in the early universe at z* ~ 1.3 that exceeds the homogeneity scale of the R-W concordance cosmology" by Roger G. Clowes, Luis E. Campusano, et. al..
This penultimate structure (LQG) is mind-bendingly large and even distorts our concepts of relativity and the cosmological principle. In "classical cosmology" it was thought that the CP limited universal structure sizes to about ~ 370 Mega-parsecs (Mpc). The newly discovered Huge LQG has an estimated size of ~ 500 Mpc - which is stupendous. Even greater is it's estimated longest dimension: ~ 1240 Mpc.
We also refer to it as the Penultimate LQG as nature is full of surprises. That is we expect an even larger LQG structure or hyper-structure may yet be discovered and described - an Ultimate LQG. The red-shift* ("z") implies that the Huge LQG lies far in the past and a long, long way away. The same may apply for the hypothetical Ultimate LQG.
This appears to upset the old (1977) documentary (and book) "Powers of Ten" and the orders of magnitude described. The book was written by the late great Philip Morrison and late wife Phylis Morrison. The office of Ray and Charles Eames (designers) was deeply involved with both projects. The previous high limit on order of magnitude (according to these good folks) was 100 million light years (~ 3E x 7 Mpc) or 10E x 24 meters.
The 7 Mpc order of magnitude (and the previous limit of approximately 150 Mpc) has long since been toppled apparently by the discovery of the Huge LQG. This begs a question - how does the Huge LQG compare in size with other large "structures" and "voids" in the known universe? How do they compare with the size of the universe?
