Neutrino Contribution to the Effective Radiation Density Through a Bounce
Year: 2026
Type: article
Abstract: This paper computes a specific neutrino quantity in a cosmology whose collapse is regulated by a maximum density, the Aldred Limit evaluated on its neutron branch at 9.72e+54 grams per cubic centimetre. The effective number of relativistic species summarises the radiation content of the early universe in one measured number. Its standard value, slightly above three, encodes the small heating of neutrinos by electron-positron annihilation during their imperfect decoupling. The calculation gives the following headline values: Neff_standard = 3.044, Neff_observed = 2.99, uncertainty = 0.17, bounce_delta_Neff = 4.1095615496779844e-49, pull_sigma = 0.31764705882352834. Each value is obtained from stated assumptions by the deposited script and is compared with published observational values where such values exist. Where the computed frame effect is far below observational reach, that negative result is stated plainly rather than softened. This study is simulated and computed from stated assumptions; it is not a measurement.
