Open Huge-LQG (U1.27) in the live scene → The scene composes a position for any date and is where a figure becomes a picture. It downloads the whole catalogue first: measured against the built product, an object outside the core resolves after about 16 s over a local network and about 147 s over a 4 Mbit link, having transferred roughly 70 MB. If you cannot wait that long, this page is the answer.

Large-scale structure — large quasar group. z = 1.27; comoving distance MODELLED from z (flat ΛCDM, Planck 2018: H0 67.7, Ωm 0.31) → ~4018 Mpc — a comoving distance is where the object sits NOW in the model, not how far its light travelled, so dividing it by c does not give a light-travel time. Anchor: mean position of the 73 member quasars computed from the paper's own membership table; z = 1.27 (the published mean redshift). Extent: "characteristic size (volume^1/3) ~500 Mpc; longest dimension ~1240 Mpc; membership of 73 quasars" (verbatim). The largest quasar group in SDSS DR7 — argued by its discoverers to exceed the Yadav et al. homogeneity scale of the concordance cosmology. [Clowes et al. 2013]

| Coverage | 14 landmark structures above the galaxy-cluster scale — superclusters (Laniakea · Virgo/Local · Shapley · Perseus-Pisces · Pisces-Cetus complex), walls (CfA2 · Sloan · South Pole · the contested Hercules-Corona Borealis, shown with its published rebuttal), voids (Boötes · Local · KBC) + the Great Attractor and the Huge-LQG. Distances from z/cz are MODELLED through the flat-ΛCDM door (Planck 2018) and labelled; cosmological recession is the expansion of space, not motion through space — no drift is modelled |
