If the universe expands by a percentage per unit time then it really would have no beginning. X number of years in the past it would have been half it's current size, 2X years in the past it would have been 1/4 it's current size, etc... At no time would it's size have been zero unless it's rate of expansion were, at that instant, infinite. Why do we think that happened?
