Abstract

We present a cosmological model (RL+) that offers exact predictions for the Hubble constant, the cosmological constant, the total energy density of the universe, and a curvature that matches current observational constraints. The model predicts a cosmological constant energy density that constitutes approximately 64% of the total energy budget, in agreement with current estimates from the standard LCDM model. Furthermore, the model addresses several longstanding cosmological problems—namely, the problem of infinite initial density, the coincidence problem, and the flatness problem—all with the introduction of a single temporal parameter.
