The two galaxies have collided previously.
Astronomers have observed their movements over time.
Astronomers know about the future collision of Andromeda and the Milky Way because they have observed their movements over time. By studying the positions and motions of these galaxies, astronomers can predict that they are heading towards each other and will eventually collide.
The correct answer is: Astronomers have observed their movements over time.
Astronomers are able to predict the future collision between Andromeda and the Milky Way through careful observation of their movements over time. They track the positions and velocities of these galaxies and can calculate their trajectories using the laws of physics. By studying the motion and interaction of these galaxies, scientists can estimate when the collision will occur and how it will impact the structure and evolution of both galaxies. This is a result of years of research and data analysis, combined with advanced computational models to simulate the future trajectories of these galaxies.
