A cosmologist was on CNN recently insulting the Catholic faith, making statements about theology which themselves proved his lack of competence to speak on the matter. In his own subject, quantum physics, he claims that the existence of negative energy proves that the universe could have come from nothing. In other words, since it is possible that there is enough negative energy to cancel out all of the positive energy, the universe might actually be nothing, like a person who has a savings account with $1000 in it and a credit card debt of $1000.
Does this really answer the problem of the unmoved mover, one of the main proofs of God's existence? Maybe, but it does not solve the problem of the necessary being who causes contingent events. If I have a debt of $1000 and a balance of $1000, it might be accurate to say that I actually have no money, but it is not accurate to say that therefore I do not use money. Perhaps the total energy of the universe does cancel out. Perhaps not. Either way, the fact that there is a reality, even one with zero-sum energy, proves the existence of God.
BTW, I thought he was at his most hilarious when he was declaring that science disproves the miracles of the Bible. Since a miracle is ipso facto an event contrary to the rules of science, science cannot disprove them. At best, science can prove that the event which occurred was actually miraculous. Science cannot prove that the sun will never rise in the west. It can only say that, if the sun ever did, it would be a miracle.
