The sky has always known

RSI argues that it does not need new data. It needs a frame that makes the existing data readable. Read in that frame, "the sky is not mysterious. It is a map."

Tolman brightness. In 1930 Richard Tolman showed that in an expanding universe, the surface brightness of galaxies must fall steeply with redshift. Deep surveys have not found the full expected dimming. Standard cosmology attributes the difference to galaxies being brighter when younger. RSI agrees with these numbers and reads them differently. It proposes that the medium's folding breathes and has been tightening, so our atoms now vibrate faster than the ones that sent distant light: redshift is a comparison of clocks, nothing is lost in flight, and galaxies are not racing away. This reading gives the same dimming as expansion, so the Tolman test cannot tell the two apart.

The Lopez rings. Alexia Lopez has reported the Giant Arc, about 3.3 billion light-years long, and the Big Ring, about 1.3 billion light-years across. Both exceed the roughly 1.2-billion-light-year scale above which the standard model expects the universe to look smooth. RSI sees them as cross-sections of vast vortex tubes in a self-similar medium.

The bulk flows. The Milky Way and its neighbors are streaming toward the Great Attractor at about 600 kilometers per second, and the known mass in that direction does not fully account for it. RSI reads this as the Universal Inhale: a large-scale pressure gradient in the medium, down which galaxies fall the way a ball rolls downhill across a contour map: the low ground does not pull the ball, the shape of the land organizes the motion.

The CMB. RSI reads its uniformity as the hum of a medium in equilibrium, its dipole as our motion through the inhale, and the Axis of Evil as the imprint of the torus's shape.

The rings, the flows and the Axis of Evil are each debated or unexplained in some respect under standard cosmology, and RSI proposes that each follows from the medium; turning these readings into predictions is the work that remains. Together, RSI argues, they draw the shape of the thing we live inside.
