Padmanabhan's emergent cosmic space proposal is employed to study the Rastall theory which involves modifying the conservation law of energy-momentum tensor. As a necessary element for this approach, we firstly propose a modified Komar energy which reflects the evolution of the energy-momentum itself in the case of a perfect fluid. After that, an expansion law is invoked to reobtain the Friedmann equation in this theory.

  1. Exploring Hubble Tension Alleviation through Neutrino-Coupled Perturbed $f(R)$ Gravity

    gr-qc 2025-02 reject novelty 2.0 of 10

    A fit of Hu-Sawicki f(R) gravity with a fitted neutrino interaction to CMB, lensing, BAO, CC, and Pantheon data returns H0 near 70 km/s/Mpc, partially easing but not resolving the Hubble and S8 tensions.
