I don’t think a galactic collision is a particularly serious event for life. The stars are so sparse that the galaxies basically pass through each other. Their large scale structure is disrupted, but that won’t kill anything living in a solar system.
- briga 9y agoIf anything I suspect a galactic collision would be a driver of increased star formation, and thus a catalyst for galactic recycling and chemical evolution within that Galaxy. It could even be something that leads to higher rates of biological evolution. And like you said, the distance between the stars is what prevents this from being a total catastrophe.
