Earlier it was shown that in the model of low-energy quantum
gravity by the author, observations of Supernovae 1a and GRBs,
which are corrected by observers for characteristic for the
standard cosmological model time dilation, may be fitted with the
theoretical luminosity distance curve only up to $z \sim 0.5,$ for
higher redshifts the predicted luminosity distance is essentially
bigger. The model itself has not time dilation due to another
redshift mechanism. It is shown here that a correction of
observations for no time dilation leads to a good accordance of
observations and theoretical predictions for all achieved
redshifts.
