Cosmological Redshift and Cosmic Time Dilation in the FLRW Metric

The paper shows that the commonly used Friedmann-Lemaitre-Robertson-Walker (FLRW) metric describing expanding Universe must be modified to properly predict cosmological redshift. It is proved change in frequency of redshifted photons always connected with time dilation, similarly as for gravitational Therefore, cosmic runs differently at high redshifts than present. Consequently, identified conformal and standard FLRW substituted by its version. correctness proposed convincingly confirmed Type Ia supernovae (SNe Ia) observations. produces essential discrepancy SNe observations called ‘supernova dimming’, dark energy has introduced comply theoretical predictions data. By contrast, fits data well no need introduce any new free parameter. Hence, discovery supernova dimming actually revealed a failure introducing was just an unsuccessful attempt cope problem within this false metric. Obviously, adopting evolution many fundamental consequences.
