The cosmic chase is ON! While our Milky Way galaxy happily bounces along through space, Andromeda lurks in the shadows like a celestial stalker. Why so serious, Andromeda? Because in about 4.5 billion years, these two galaxies are destined for the ULTIMATE cosmic collision! It's like watching the slowest horror movie ever where the victim is cheerfully oblivious and the monster moves at 110 km/second. Spoiler alert: when they finally meet, they'll merge into one giant elliptical galaxy that astronomers have already nicknamed "Milkomeda." Talk about the universe's most extreme long-distance relationship!
