The science adviser for “Don’t Look Up,” a star-studded comedy about a killer comet, has some serious advice for dodging a threat from the skies: Take the title of the movie, and do the exact opposite.
“The sensible thing to do about this particular problem is … just go look up and see if it’s out there,” said Amy Mainzer, a planetary scientist at the University of Arizona’s Lunar and Planetary Laboratory. “And do a thorough enough job of it that we have a reasonable chance of spotting something that’s large enough to cause appreciable damage, well before it could make its way here.”
The roughly 5-mile-wide comet that’s heading for Earth in “Don’t Look Up,” with only about six and a half months of advance warning, is totally fictional. Nevertheless, the movie is a teachable moment for the science surrounding asteroids, comets and planetary defense. And Mainzer said the stars of the show, including Leonardo DiCaprio and Jennifer Lawrence, were unusually eager students.
“These actors wanted to know everything,” she said. “I would say they’re approaching some pretty solid knowledge of just how do we find asteroids and comets, and what do we do about them.”
Mainzer discusses what’s going on with the search for potentially threatening near-Earth objects, as well as her experience as a science adviser for “Don’t Look Up,” in the latest episode of the Fiction Science podcast, coming to you from the place where science and technology intersect with fiction and popular culture.
