A Model of Dark Matter and Energy
Paul H. Frampton
TL;DR
The paper proposes a cosmology in which dark energy is not a separate component but arises from electrically charged, extremely massive primordial naked singularities (PEMNSs) that constitute a large fraction of dark matter. Through a classical treatment with $M_{Planck}=0$, it derives a cosmological constant of order $\Lambda \sim O((meV)^4)$ and shows PEMNSs generate a negative pressure with an equation of state $\omega \approx -1$, effectively replacing dark energy in the Friedmann dynamics. The model distinguishes Old DM (PIMBHs and SMBHs) from New DM (PEMNSs) and analyzes entropy and time evolution, predicting a decaying $\Lambda(t) \propto t^{-2}$ and a future extroverse growth markedly different from $\Lambda$CDM, with potentially observable remnants of the alternative cosmology. If borne out, this framework offers a testable, non-quantum-gravity-based explanation for cosmic acceleration and a new perspective on the entropy and fate of the universe.
Abstract
We discuss a model of the universe where dark energy is replaced by electrically-charged extremely-massive dark matter. The cosmological constant has a value of the same order as the mean matter density, consistent with observations, and is obtained classically without fine-tuning.
