Cosmology of a sentient information sector: a thermodynamic information–energy bridge, dynamical dark matter and dark energy, and three perturbative signatures

This preprint develops the cosmology of a sentient information sector: an extension of the Einstein equations in which the dark sector is sourced by a scalar field carrying integrated-information density. The construction proceeds through three layers. First, a thermodynamic information–energy bridge relates energy density to integrated information through a non-linear maintenance function, recovering the linear Landauer relation as a limiting case. Second, accumulated information is modelled as a pressureless component reproducing cold-dark-matter phenomenology at background level, while a geometric tensor from a Kaluza–Klein reduction on a Kähler moduli space generates perturbative signatures. Third, a…
