Reply to comment by charmingpea in What happens when galaxies are passing by each other, and 2 stars smack into one another? by Kitkatphoto

I don’t believe that’s correct. There are galaxies that have collided. This makes me think there was more than one bang. It’s been hypothesized that the Milky Way will collide with Andromeda in 4.5 billion years.

It's not a hypothesis our galaxy and Andromeda are on a collision corse. They are flying towards each other at break neck speed relatively speaking. However that being said our two galaxies are absolutely insignificant in size compared to the universe. The collision of 2 galaxies would be nothing in comparison to the big bang. Think of it like this it would be less noticeable than 2 subatomic particles colliding in a massive galaxy cluster. Or as noticeable as a human burp in our local group of galaxies.
