Earth’s perilous journey through the Milky Way may shape geology

Earth’s journey through the Milky Way may have had a profound impact on our planet’s geology. New research indicates that every 200 million years, when Earth passes through its galaxy’s spiral arms, the planet is pummeled with high-energy comets, and this bombardment may thicken Earth’s continental crust.

The team behind the new findings thinks the dense clouds of gas in the spiral arms interact with comets at the edge of the solar system, sending them hurtling toward Earth.
