Galaxy question

  1. Jan 4, 2014 #1
    How many other galaxies, have a similar trajectory of being on a crash course path with a neighboring galaxy. Is it a consensus that most galaxies are moving away from one another due to dark energy, if so is there a ball park figure of those like the Milky Way and Andromeda?

    Most galactic CLUSTERS are moving away from each other. Within clusters, such as our Local Group, galaxies have some modest relative motion and various of them may be on a collision course with each other. I have no idea how many.

    Thank you, I forgot the other variable that we are in a galactic cluster!
