... Millions of years from now? I imagine advanced civilizations in both galaxies doing complex calculations as to the galaxy approach speed, their own potential space flight speed, their other technology relating to long-term travel, suspended sleep, etc., to determine JUST the right time to shoot out from one galaxy to the other. You will see a stream of ships from both galaxies shooting across the narrowing void over the course of thousands of years. Many of these will be aimed at trying to conquer some regions of the other galaxy. Shots will be fired. There will be great explosions and many deaths. A galactic war will rage as civilizaiton(s) from one galaxy try and conquer the other, and vice versa.
