What is a good interview question for Chris Boone from "The Curious Incident of the Dog in The Nighttime"?

Chris is so interested in astronomy. His Asperger’s, in part, enables to understand his science so well yet he has a detached sense of social "norms". I might ask him how he feels about the fact that humans are, theoretically, made of stars or stardust. I really don't know how Chris would answer that but I bet his answer would be unique and thought provoking.
