I don't see the next step (saying that matter is therefore infinite) as obvious. Is it then thought that there was infinite energy in the Big Ban? As I'm sure you appreciate there's an awfully big difference between a very very large amount of matter and an infinite quantity. That was the essence of my previous argument: we must not be so daunted by the size of the universe as to apply arguments which are only valid when considering infinite systems.:
Any part of an infinity can be broken into what we would say for want of a better word a smaller infinity it is however correct to call this infinity also.
