The Milky Way's structure may have shaped Earth's continents

Scientists have proposed that the spiral arm structure of the Milky Way may have influenced Earth's geology, including the distribution of its continents. As the Solar System passes through denser galactic regions, increased meteorite bombardment and cosmic radiation could affect plate tectonics. The hypothesis offers a new perspective on the link between galactic evolution and Earth's geological history.
