Why 'Gravitational' Waves Are Better Understood as Space‑Phase Measurements

So called ‘Gravitational waves’ are commonly described as ripples of gravity ordisturbances of spacetime geometry, despite the fact that gravity is no longer treated as aforce in modern physics. This paper argues that such language obscures what is actuallybeing measured. Within the SP3 framework, gravitational‑wave observatories are bestunderstood as instruments that directly probe the physical behavior of space‑phase itself.Violent astrophysical events do not transmit force across the universe; rather, they disturbthe space‑phase substrate, which then rebounds, transports strain, and retains memory.Interpreting ‘gravitational waves’ as space‑phase measurements resolves long‑standingconceptual tension between geometry, energy transport, and memory, while preservingall validated observations.
