Echo Delay of a Gravitational-Wave Burst Reflected at a Torsion Turnaround: A Computed Timing Signature
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. A distinctive feature of a non-singular turnaround is that it is a place, not an edge: waves can interact with it, and a partial reflection would return a delayed copy of a burst whose separation encodes the width of the bounce layer. The headline results of the computation are: t_Hubble_bounce_s = 4.29e-25, fiducial_delay_proper_s = 8.58e-26, fiducial_delay_observed_s = 1.03e+06, layer_fraction_fiducial = 0.1. 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.
