In this paper, we have given some analysis from observations of type Ia supernovae (SNIa). We find that the average total observational error of SNIa is obviously greater than 0.55^m. On the other hand, a popular view of circumstantial evidence for the accelerating universe comes from the comparison of theoretical models simulating the accelerating expansion of the universe with observations from the Wilkinson Microwave Anisotropy Probe (WMAP) satellite deviating from the observed isotropic temperature of the Cosmic Microwave Background (CMB). Due to the fact that the velocity space is not isotropic, then the theoretical simulations are incredibly consistent with observations from the WMAP and Planck satellites. We conclude that the anisotropy of the velocity space will inevitably lead to an anisotropic distribution of the CMB temperature, and the above indirect evidence of the cosmic acceleration is inadequate and inappropriate.
