The Implications of an Infinite Past

Trent Horn suggests that an infinite regress of past events would imply the possibility of a simultaneously existing, actually infinite number of things today. According to him, the objection that past events do not exist at the same time is irrelevant as long as the objects are definite and discrete, adding up to an actual infinite collection. He argues that even if the objects do not exist simultaneously, the absurdities remain. For example, he mentions the thought experiment of an infinite number of iron pellets piling up outside a hotel, highlighting that considering subsets within the collection results in an equally infinite number of objects. Therefore, he maintains that an infinite past is metaphysically impossible and defends the view that the temporal becoming is real and objective.
