Limits of Absolute Identity

Absolute identity obeys Leibniz's Law in that if x equals y then every detail about x is exactly the same as every detail in y and vice versa. For example, every physical object at any given point in time is absolutely identical to itself. However, every physical object changes with the elapse of time. From one Plank time to the next, every physical object changes at the subatomic level according to quantum mechanics. Likewise, no physical object is absolutely identical to itself from one Plank time to the next. This could mean that no objects continue to exist from one Plank time to the next or objects that continue to exist during the elapse of time have limited/relative identity.
