Toroidal Geoflow as a Source of Gravitational Wave Polarization Anisotropy: A Falsifiable Prediction for Einstein Telescope

We propose that toroidal topology of space predicts a systematic anisotropy in the polarization angle ψ of gravitational waves accumulated over cosmological propagation distances. Under the toroidal geoflow hypothesis, the phase desynchronization between h+ and h× polarization modes scales as ∆Φ ≈ (2ωR/c)·(cos ϕ1 −cos ϕ2), where ω is the angular velocity of the global geoflow, R is the luminosity distance, and ϕ1, ϕ2 are angles between the wave propagation vector and the toroidal axis.
