The Day Andromeda Hits the Milky Way: What Happens to Us? | Sleep to Science

A galaxy collision sounds like instant destruction—until you learn it’s a billion-year slow-motion dance where even two star-filled galaxies can pass through each other without a single star-to-star crash. Tonight, we’ll trace how these encounters really work: the invisible gravity that pulls galaxies together, the long multi-act “romance” of approach and re-approach, and the dramatic changes collisions trigger—new stars, stretched tidal ribbons, and even merging black holes—explained in a clear, easy-to-follow way. We’ll break it down so it makes sense on the first listen, including the future meeting between the Milky Way and Andromeda. Chapters: 1. The shocking scale—and the “no stars collide” paradox 2. Dark matter: the invisible choreographer of the dance 3. The 5-act timeline of a galaxy merger 4. What collisions create: starbursts, tidal tails, and reshaped galaxies 5. The Milky Way vs Andromeda: our future encounter 6. Real collision scenes across the universe 7. Strange “artwork” galaxies born from impacts 8. Why collisions shaped cosmic history—and what ends them If you enjoy science that’s easy to follow at night, subscribe for more.
