Consider the small-scale ingredients of each world, how they undergo constant change. Like buzzing mosquitoes, they hatch into existence, grow, change, die and vanish. And it is specifically change (motion, growth, and the release of energy) that renders events and objects observable.
Thus if a small piece of a world can (and must) change, wouldn’t it follow that a larger piece—even the world itself—must also be impermanent?
This concept—that truths about the large can be deduced from truths about the small— lies at the heart of the research to which Cassie and I have committed our lives. I will hereafter refer to it as The First Law of Scale.
