Entropy Growth per Cycle in a Cyclic Bounce and the Heat-Death Avoidance Test
Year: 2026
Type: article
Abstract: The claim of identical eternal cycles fails the arithmetic. With any positive production per cycle, successive cycles are larger and longer, the sequence terminates against the entropy maximum after a finite computed number of cycles, and running the sequence backward reaches implausibly small cycles after a finite count as well. Exact repetition requires exactly zero production, which no irreversible process in the contents supplies. The computation is performed from stated assumptions in a density-limited bounce, in which the neutron-branch limit density sets a maximum density, a finite bounce temperature, and a minimum horizon size. Headline values from the deposited calculation are: dS_fraction_per_cycle = 0.05; cycles_to_max_entropy = 1.56e+03; cycles_back_to_floor = 69.7; verdict_identical_eternal_cycles = fails. The study is simulated and computed, not measured, and its conclusions are stated at the precision the stated assumptions support.
