An Ocean Crust Holding an Older Galactic Clock

Traces of plutonium-244 in Pacific crust carry a record of heavy-element production beyond Earth. Missing curium helps constrain when that production occurred, but the oldest headline estimate depends on how the crust incorporated the elements.

05 Correlation and causation

Connect a hidden process to an observable effect.

Earth’s interior and environment are studied through signals, samples, and models. A proposed mechanism should link them with the effect it is meant to explain. Compare alternatives and the conditions of each record rather than relying on a suggestive coincidence.

Ask yourself What evidence connects the proposed cause to the effect beyond their appearing together?
