Yes. The first article cited below discusses evidence that some of M31's globular clusters are remnants of past galactic cannibalism events. The latter article looks even further away and finds signs of an entire class of dwarf galaxies that have been torn apart by some larger galaxy.its not trick question , its about , if we can think and give evidence to the way the Milky Way is with sagittarius , then why not any other similar galactic situations
are there simular situations as there are between the Milky Way and sagittarius in the Universe ?
