In controlled laboratories, scientists have begun to answer one of planetary science's quieter questions: how long does it take a world, however small, to come undone? By tumbling meteorites under repeatable conditions, researchers have discovered that the timescales for asteroid disaggregation span six orders of magnitude — a range so vast it reframes our understanding of how rocky bodies age, endure, and ultimately dissolve across deep time. Paradoxically, the very act of crumbling generates fine dust that cushions further destruction, offering an explanation for why fragile rubble-pile aste
