Episode Description from the Publisher

What superhero would Neil deGrasse Tyson be? Where would he go if he could travel through time? And how much bad science will he forgive if a movie tells a great story? And how he grew up an athlete who lived in the geekosphere.In this special bonus mini-episode of UNOBTAINIUM, planetary scientist Dr. Amy Mainzer and producer Adam Sigel revisit their conversation with Neil deGrasse Tyson for a wide-ranging trip through science, science fiction and geek culture. Neil reveals why he once imagined himself as “Protector of the Geeks,” explains why the Marvel Universe has a scientific edge over other superhero worlds, and shares his personal rule for giving filmmakers a “hall pass” when the physics isn't quite right. Along the way, we get Neil’s takes on the scientifically impossible storm that launches The Martian, why we happily accept the flux capacitor in Back to the Future, whether real physics could make time travel possible, why he'd rather visit the future than the past, and which ideas might someday let us cross the enormous distances between the stars. Plus: faster-than-light travel, cryosleep, alien civilizations, 2001: A Space Odyssey, Comic-Con, superheroes, atomic wedgies, and the Revenge of the Nerds. If you enjoyed this conversation, check out our full episode with Neil deGrasse Tyson on STAR WARS, the Force, and the science behind a galaxy far, far away. UNOBTAINIUM explores the real science behind the movies and television we love, with scientists, filmmakers and other extraordinary guests. Subscribe for more conversations at the intersection of science, movies, television and pop culture.   Follow Unobtainium Podcast! Website: unobtainiumpodcast.comWatch full episodes on https://www.youtube.com/@unobtainiumpod Stay connected: Instagram: @unobtainiumpod TikTok: @unobtainiumpod Bluesky: @unobtainiumpod.bsky.social X: @unobtainiumpod For Neil deGrasse Tyson: Instagram: https://www.instagram.com/neildegrassetyson Youtube: https://youtube.com/@startalk Tiktok: https://www.tiktok.com/@neildegrassetyson?_r=1&_t=ZT-9736KZJtaIA #NeildeGrasseTyson #starwars #science #scifi #unobtainiumpodcast #physics #space #force #film #moviescience #NeilDeGrasseTyson #ScienceFiction #SciFi #Science #Movies #TimeTravel #Superheroes #Marvel #TheMartian #BackToTheFuture #Aliens #UnobtainiumPodcast #physics #moviescience Hosted on Acast.
