What happens when two galaxies collide? What would happen and what are the chances that our galaxy will collide with another?
In: Physics
Galaxies colliding all the time. Normally the space between stars in each galaxy allows for almost no stars to collide with each other. I’m sorry I dont know the numbers off the top of my head. During this process the galaxies form an almost pretzel like shape.
The milky way galaxy in a short time for galaxies ( billions of years) is going to collide with the much larger andromeda galaxy. If you could see andromeda with no milky way stars in the way it would appear about 2 times the size of the moon.
