Earth’s dangerous journey through the galaxy could affect geology

Earth’s journey through the galaxy may have had a profound impact on our planet’s geology. New research suggests that every 200 million years, Earth is bombarded by high-energy comets as it passes through the spiral arms of its galaxy, a bombardment that could thicken Earth’s continental crust.

The team behind the new findings believe that the dense cloud of gas in the spiral arms is related to comet on the edge solar systemlet them fly to Earth.
