[Date Answered] February 21, 2011 [Questioner (age, location)] Ardhendu(Andhra Pradesh/ India) [Question] What is the creation of universe related with the principles of matter and antimatter and how were the first moments of universe in relation to the same? Thank You [Answer] 
According to the article Baryon asymmetry, "The Big Bang should have produced equal amounts of matter and antimatter... Since this is apparently not the case, after the Big Bang, some physical laws must have acted differently for matter and antimatter. There are competing theories to explain the matter-antimatter imbalance that resulted in baryogenesis, but there is as yet no one consensus theory to explain the phenomenon."
