Conformal Cyclic Cosmology from Varying Fundamental Constants

We investigate a bimetric cosmological model in which the gravitational and matter sectors are described by distinct metrics related through a time-dependent function $\alpha(t)$. This relation leads to dynamical gravitational parameters, with $G(t)\propto\alpha^{-3}$ and $c_{\rm grav}(t)\propto\alpha^{-1}$, where $c_{...
