New explanation for accelerated expansion and flat galactic rotation curves
Abstract Employing the non-additive Tsallis entropy, $$S\sim A^{\beta }$$ S∼Aβ , for the large-scale gravitational systems, we disclose that in the cosmological scales both the Friedmann equation and the equation of motion for Newtonian cosmology get modified, respectively. We then derive the modifi...
