"The Impending Collision: Milky Way and Andromeda"

In about 4 billion years, the Milky Way will collide with the Andromeda galaxy, forming "Milkdromeda" or "Milkomeda." During the collision, the supermassive black holes at the center of each galaxy will merge, and there's a 50% chance that the solar system will be pushed three times farther from the galactic core. Ultimately, the collision will make Earth too hot for liquid water to exist, leading to the end of all terrestrial life on the planet.
