Because the distances between the stars are so great compared to their sizes, few if any stars in either galaxy will actually collide. Any life on the worlds of that far off future should be safe, but they will be treated to an amazing billion-year-long lightshow. A dance of a half a trillion stars, to music first heard on one little world, by a man who had but one true friend.
