Scientists Discover a 4-Billion-Year-Old of Earth’s Crust

Curtin University researchers have discovered evidence of an approximately 4 billion-year-old piece of the Earth’s crust that exists beneath the South-West of Western Australia by using lasers smaller than a human hair to target microscopic grains of a mineral extracted from the beach sand.

This discovery helps explains how the planet evolved from being uninhabitable to supporting life.
