【 摘 要 】
Some serious faults in error analysis of observations for SNIa have been found. Redoing the same error analysis of SNIa, by our idea, it is found that the average total observational error of SNIa is obviously greater than 0.55m, so we cannot decide whether the universe is accelerating expansion or not.
