Using Unruh temperature and generalized chemical potential as alternative pathway to determine the Hubble parameter
Hubble constant is found relating velocities and distances of galaxies. Actually Cepheid stars and cosmic background radiation present two distinct values for the Hubble constant. Theoretically such a Hubble parameter naturally emerges from the scale factor variations considered in cosmological mode...
