Maybe not (or may be, I suppose) what parent was referring to, but consider the following possibility: "People assume that time is a strict progression of cause to effect, but actually, from a nonlinear, nonsubjective viewpoint it's more like a big ball of wibbly-wobbly, timey-wimey... stuff." -- The Doctor [1] To be a bit more serious, causality in general is (by some accounts) an open philosophical problem. That is, there's no generally accepted proof (and not even really a concept of what would prove or disprove) that causality actually exists as an independent rule/law/standard/phenomenon, as opposed to being an abstraction of correlation that we made up to reason about our decisions [2]. For all we know it may be that an effect without a cause violates merely our intuitions, not the laws of nature.
