So the title of a video I've watched for immersion (https://www.youtube.com/watch?v=qmd_p5qnzCM) is the following : 天の川がアンドロメダと衝突したとき何が起こるか
I would translate it to something like "When the milky way collided with Andromeda, what happens" and that makes no sense to me. The problem is, it has not yet happened ( I'm talking about the andromeda and milky way collision), so I thought it shouldn't be present?
Can you explain this to me?
