The Real Cosmic Web

25,000 SDSS galaxies · relaxation-labeled

This wedge is real: every point is a galaxy the Sloan survey measured, placed by its redshift. You are looking at the actual Cosmic Web — filaments strung between clusters, draped around vast empty voids. Then the relaxation engine labels the web from each galaxy's local density: the clusters are the clogged, stagnant knots; the voids are the free-flowing expanse; the filaments are the bridges between.

What's real. The galaxy positions and the web are real SDSS DR17 data (a 4°-thick Dec slice, z<0.15). Comoving distance uses d = (c/H₀)·z with H₀=70 — the radial "fingers" pointing at the apex are the classic redshift-space distortion (Fingers of God): clusters smeared by their own orbital motion, itself a signature of unseen mass. The void/filament/cluster labels come from the same relaxation engine as the rest of this site, run on the galaxies' local density.

Where it meets our model. Clusters = the clogged, dark-matter-dominated knots; voids = the free-flowing, dark-energy expanse — the same poles, now sorted from real cosmic structure instead of synthetic parcels.
