Redshift of a photon by interaction with the permittivity and permeability of the traversed medium: Hubble's Law in the stationary and freely extending universe

Abstract

Hubble's law can be explained as a redshift of a photon caused by its interaction with the permittivity and permeability of the medium through which it is traveling. The Hamiltonian density of the photon and medium is represented as H ¼ ðp 2 m =2q E Þ þ n p "x (p m ¼ momentum of the medium, q E
