摘要
The beginning of the cosmological phase bearing the direct kinematic imprints of supernovae (SNe) dimming may significantly vary within different models of late-time cosmology, even if such models are able to fit present SNe data at a comparable level of statistical accuracy. This effect-useful in principle to discriminate among different physical interpretations of the luminosity-redshift relation-is illustrated here with a pedagogical example based on the Lemaitre-Tolman-Bondi geometry.
