Do galaxies interact?
Question asked by: knowitall
This is an interesting question.
Of course we have no direct evidence of galaxies interacting but it does appear that they can and do, and are at this very moment, interacting.
Usually a violent and energetic affair, galaxies interacting will cause much destruction of existing material and then result in a product phase of much star formation and activity as the repercussions are felt throghout the galaxy.
