I rewatched "The Expanse" yesterday. An awesome episode, just like the first time I saw it, but when Malcolm and Trip looked over the huge canyon the weapon created, I started wondering: damn, that's a huge canyon, I wonder how they got rid of it? Did they fill it up? (If so, where would they get enough soil to fill up a 2 kilometre wide, 4000 kilometre long canyon?) Did they make a channel out of it? Did they keep it around as a memorial to the seven million people who had died? Any thoughts on this?
