Neil deGrasse Tyson has turned his lifelong fascination with aliens into a new book, “Take Me to Your Leader: Perspectives on Your First Alien Encounter.” Tyson explores what we know about extraterrestrial life and what an encounter might be like. He suggests that aliens would likely be far more advanced than humans, making Hollywood’s depictions of fighting them seem laughable. The book blends pop culture with science, referencing everything from “Rick and Morty” to Voltaire. Tyson believes science could be a universal language for communication. The book arrives amid renewed interest in UFOs and aliens.
