Nodal Precession of the LAGEOS Satellites and the Frame-Dragging Prediction of a Torsion-Regulated Frame
Year: 2026
Type: article
Abstract: This paper computes the Lense-Thirring nodal precession for the LAGEOS laser-ranged satellites in Earth orbit within a torsion-regulated gravitational frame — Einstein-Cartan gravity with the density bound that follows from its spin-torsion term — and compares the result with the best published measurement. The relativistic prediction is 30.67 milliarcsec per year; the published value is 30 plus or minus 3 milliarcsec per year, a residual of -0.6691 milliarcsec per year (-0.223 standard deviations). Because torsion in this framework is sourced only by spin density and does not propagate, the predicted deviation from general relativity is set by the square root of the ratio of the system density to the bound density, giving a fractional deviation of 7.533e-28 and a correction of 2.31e-26 milliarcsec per year. The measurement bounds any fractional deviation at 0.2175 (two standard deviations), so the framework passes this test with a headroom factor of 2.887e+26. Stated plainly, the test is consistent with the framework but cannot distinguish it from general relativity; the implied lower bound on the density scale, 1.166e+05 kilograms per cubic metre, lies far below the framework's bound of 9.718e+57 kilograms per cubic metre. The study is computed from stated assumptions and published data; it is simulated, not measured.
