What do astronomers expect will eventually happen to the milky way galaxy? the milky way will collide with andromeda in 3 billion years forming an elliptical galaxy the milky way will wipe out andromeda with interstellar dust and particles as they collide the gravitational attraction between the milky way and andromeda will collapse them into a black whole as they collide the milky way and andromeda will largely just pass by each other as they approach

The first one: the Milky way will collide with Andromeda.

Answer;

The Milky Way will collide with Andromeda in 3 billion years forming an elliptical galaxy

Explanation;The milky way is the galaxy that contains our solar system, while the Andromeda is a spiral galaxy that is the nearest major galaxy to the milky way.It is predicted that the milky way will collide with Andromeda which is our large spiraled neighbor, and merge in about 4 billion years between  two galaxies in the local group.The two galaxies are believed to collide head-on and fly through one another, leaving gassy, starry tendrils in their wakes.
