Gravitational-Wave Propagation Through a Torsion Bounce: Speed, Damping and Phase Advance Computed Mode by Mode
Year: 2026
Type: article
Abstract: This study computes a specific gravitational-wave consequence of a torsion-regulated bounce in Einstein-Cartan gravity, taking the limiting density for neutron matter, 9.72e+54 grams per cubic centimetre under the stated prescription, as its single input scale. Between generation and observation, primordial tensor modes must cross the bounce itself, and that crossing can damp them, amplify them, or advance their phase; this study computes all three effects for a stated bounce profile. The headline results of the computation are: long_mode_phase_advance_rad = 4.11e+00, short_mode_phase_advance_rad = 1.00e-02, speed_in_vacuum = c (exact in this theory). Each quantity is evaluated by the deposited script from the assumptions stated in the Methods, and the agreement or disagreement of each quantity with published observational bounds is reported at face value, including where the conclusion is that the channel examined is closed. The study is simulated and computed from stated assumptions; it is not a measurement, and no observational data were taken for it.
