What the LIGO-Virgo O3 Stochastic Bound Already Excludes for Torsion Bounce Backgrounds
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. Rather than asking whether a bounce background is detectable in principle, this study asks the sharper question of which portion of its parameter space present data have already closed. The headline results of the computation are: O3_limit = 5.80e-09, excluded_fraction = 0.31, grid_total = 48, grid_excluded = 15, fiducial_Omega_25Hz = 6.25e-08, fiducial_margin = 9.28e-02. 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.
