[BONUS] The Sky Isn’t the Limit. Interview with me on The Last Easy Mile Podcast
This is an interview with me on The Last Easy Mile podcast with Josh Farahi. Video version: https://www.youtube.com/watch?v=lFRZvPc3U&ab_channel=TheLastEasyMilePodcast THE LAST EASY MILE: https://linktr.ee/TheLastEasyMilePodcast In this episode, Fraser Cain—founder of Universe Today and co-host of Astronomy Cast—shares why space still matters. From watching meteor showers with your kids to seeing Saturn’s rings through binoculars in a city, Fraser offers practical ways to reconnect with awe. He reflects on raising science-minded kids, his love of tabletop RPGs, and how parents can create deeper imaginative experiences than screens can provide. We also talk about the James Webb Space Telescope, the Mars rovers, and the Vera Rubin Observatory, which will capture time-lapse images of the sky. Fraser warns against the growing distrust of experts, advocating for humility, critical thinking, and Carl Sagan’s “baloney detection toolkit.” 📰 GUIDE TO SPACE Newsletter No ads.
