Gravitational-Wave Memory of a Torsion Bounce: Permanent Displacement from the Turnaround Itself

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. Gravitational-wave memory is a permanent displacement left after a burst passes; this study asks whether the bounce itself, the most energetic event in the history of a bouncing universe, leaves such a displacement at a level any instrument could register. The headline results of the computation are: E_patch_J = 7.78e+27, fiducial_memory_strain = 2.24e-24, anisotropic_fraction_fiducial = 0.01. 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.
