A medium-based, magic-free physical picture of the world: flat Galilean space; a real superfluid-vacuum medium; Le Sage / shadow gravity with finite range; light as re-emission by the medium; a non-expanding ("breathing") universe (tired light + coasting cosmology, q0=0) rather than metric expansion; the CMB as a cooling remnant; collapsars as sources of matter without event horizons; superluminal jets (M87); chromatic gravitational-lensing dispersion; and a preferred-frame resolution of faster-than-light signaling and causality, with a critique of "light-centrism".
