Does a Collapsing Stellar Core Violate the Bekenstein Bound Before the Bounce? A Direct Check

This paper examines the suggestion that a collapsing stellar core must violate the Bekenstein bound before any bounce can intervene. The calculation is performed in a frame with a finite maximum density, the neutron-branch value rho_A = 9.718e+57 kg per cubic metre, with the electron branch at 2.874e+51 kg per cubic metre for comparison. Headline results include a bounce temperature of 3.278e+22 K, a Landauer cost at that temperature of 3.137e-01 J per bit against 2.871e-21 J per bit at 300 K, a Bekenstein allowance of 1.049e+94 bits for the stated centimetre reference region, and a Margolus-Levitin rate of 2.209e+103 per second for the same region. On the stated track the ratio remains satisfied up to the bounce density, so no violation forces new physics before the density ceiling itself acts. All numbers are computed from the stated assumptions in the accompanying script; the study is simulated and computed, not measured.
