Supernovae - Opis:
- We have relaxed the constraint of adiabatic universe used in most cosmological models and shown that the new approach provides a better fit to the supernovae Ia redshift data with a single parameter, the Hubble constant, than the standard ΛCDM model with two parameters, the Hubble constant and the cosmological constant. The new approach, developed within the confines of the cosmological principle, yields the Hubble constant value 69.01 (±0.53) km s-1 Mpc-1. The cosmological constant may thus be considered as a manifestation of a non-adiabatic universe that is treated as an adiabatic universe.
