Abstract
Inspired by the recent literature, we study the Einstein–de Sitter cosmological model coupled with a generalization of the relation between the redshift and time dilation of the kind δt0=δte(1+z)n. We find that this model fits the experimental data regarding 1048 supernovae, in a way which is competitive with the standard ΛCDM model and without the need of introducing a non-zero cosmological constant. Since the existence of dark energy, as a main ingredient of the composition of the cosmos, is still under debate, we propose our formalism as an example of an alternative description of the cosmological scenario.File in questo prodotto:
