Texture Unwinding Against the Shear Ceiling: Gradient Energy, Collapse Time, and the Largest Event the Bounce Allows

This paper computes a consequence of the torsion-regulated bounce for topological defects, using the density ceiling of 9.718e+54 grams per cubic centimetre and the maximum temperature of 3.278e+22 kelvin that follows from it. The largest bounce-era unwinding releases 5.301e+19 GeV, which is 8.493e+09 joules, the energy equivalent of 9.449e-08 kilograms, on a collapse time of 4.290e-25 seconds, the light-crossing time of the bounce horizon. Textures unwinding later, at ten and one hundred times the bounce horizon, release 5.301e+20 GeV and 5.301e+21 GeV respectively, growing linearly with size while their number density falls. The gradient energy of a bounce-horizon texture is a fraction 1.091e-18 of the ceiling energy in its horizon volume, so textures pass the budget check comfortably: they are allowed configurations whose effects are small, not forbidden configurations. The shear ceiling, in this instance, does not add a further restriction beyond the density ceiling, and the paper records that as a checked negative rather than assuming it. The calculation is performed from stated assumptions with all arithmetic deposited, and it is a computation, not a measurement.
