Curiosity killed the cat, but satisfaction brought him back.
Tyson will always be endlessly curious and the unknown is simply a new puzzle for him to play with.
Finding something that he doesn’t understand and getting to poke at it until he does understand it is one of Tyson’s favourite parts of science and mathematics, and his work with the Moriarty Mirrors.
He has an ingrained fear from childhood about being reprimanded for not knowing everything - to admitting that he doesn’t know something that he feels as though he should, which is everything - but that doesn’t dim the spark of wonder in Tyson’s eyes when he finds something new.
He is a scholar in his heart of hearts. Any new knowledge to discover is a gift.
