Michelson–Morley, Redshift, and the Politics of Structure in Space

The Michelson–Morley experiment is widely portrayed as having demonstrated that spacehas no structure, no medium, and no physical character beyond abstract geometry. Thispaper argues that such a reading is historically inaccurate and sociologically conditioned.Michelson and Morley tested a narrow hypothesis: the existence of a stationary,mechanically rigid luminiferous ether that would produce a detectable directional variationin the local speed of light. They explicitly did not claim that space lacks structure.Subsequent developments—particularly Hubble’s discovery of cosmological redshift—probed a fundamentally different regime: cumulative, long‑range transport effects ratherthan local kinematics. This paper examines how early twentieth‑century physics, undersocial, institutional, and reviewer‑driven pressures, adopted a language of geometry whilequietly retaining many medium‑like behaviors. Within the SP3 framework, these historicalchoices are re‑examined, revealing that a mobile, reconfiguring space‑phase would passMichelson–Morley while naturally accounting for redshift, energy taxation, and large‑scalememory effects.
