A few years ago, on a flight, I was seated next to a man in his mid-20s. He looked at the astrobiology textbook I was reading and asked if I was a scientist. When I told him I was, his face lit up and he told me how much he loved science. He listened to podcasts like “The Joe Rogan Experience” and others where scientists came on as guests and talked about quantum mechanics, black holes and ancient aliens.

Encouraged by his enthusiasm, I told him that not everything on those shows was science (case in point: ancient aliens). I advised him to be on his guard. Then, with all earnestness, he told me while I was clearly OK, it was common knowledge that sometimes, on some subjects, science hid the truth.
