earthshattering

Changing everything fundamentally

Earthshattering describes events or revelations of enormous significance—momentous enough to shake the foundations of what came before.

The word is often used hyperbolically: It's not exactly earthshattering news that teenagers like to sleep late.

Genuinely earthshattering developments change how we understand something fundamental.
