Seen in an unencumbered night sky, far from the glare of city lights, it seems magnificent and eternal in its enormity. Nothing could shift this ancient web of stars, nothing could disturb its transcendent stoicism.
Except, that is, another galaxy. Galaxies orbit millions of light-years apart, but gravity, the immutable magnet of the cosmos, can pull them together, producing spectacular collisions that reshuffle stars. According to the leading theory, the Milky Way will collide with one of its closest neighbors, Andromeda, sometime between 6 billion and 8 billion years from now.
