The Fingers in Stars and Salt DomesHow the universe reuses its best structural patterns.

A single physical principle explains the formation of eerily similar patterns across the cosmos and deep within our planet. When a heavy fluid is pushed into a lighter one, it creates intricate, finger-like structures. This phenomenon sculpts the filamentary clouds of an exploded star and, over millennia, forms massive salt pillars deep underground. It's a striking example of how the same fundamental physics can shape our universe on every scale.
