Our Possible Future: Three Scenarios for a Future Encounter Between the Milky Way and Andromeda Galaxies: Top Left: The two galaxies pass each other at a distance of a million light years. Top Right: As the distance between them decreases to 500 light years, the friction exerted by dark matter causes them to approach for a close encounter. Bottom: A distance of 100 light years leads to a collision. (Courtesy: NASA / ESA)
