Ok, forget about the notion of objective time then, and just think about

whether the universe contains an observer moment when the oberver

perceives that the computer has gone through an infinite number of

cycles. The answer is no in the CSO case since at any given moment in the

universe an ordinary computer would have gone through only a finite

number of cycles.
