Joining Bill Nye is Casey Dreier, Chief of Space Policy at The Planetary Society, who provides insights into NASA's funding challenges. They discuss the proposed budget cuts that threaten NASA’s scientific missions, particularly in Earth observation and astrophysics. Casey emphasizes the crucial role of public funding for space exploration amidst political pressures and the rise of commercial space. They also explore the implications of Mars missions, innovative technologies arising from ambitious projects, and the cultural importance of investing in science.

Jake Roper, a YouTube creator from Vsauce3, explores the fascinating world of aliens in film with Neil deGrasse Tyson. They discuss the easiest alien movie to survive, with Jake choosing 'E.T.' and diving into quarantine risks. The conversation shifts to the plausibility of laser weapons and the existence of organizations like Men in Black. They debate who to send on a first-contact mission, ponder survival strategies during an alien attack, and consider the most believable sci-fi alien depictions. Roper's insights make for an entertaining and thought-provoking dialogue.

In this engaging discussion, astrophysicist Charles Liu, a professor at CUNY, delves into the science behind iconic monsters like Godzilla and zombies. Liu explains how Godzilla emerged as a cultural symbol of nuclear anxiety. He explores why a 400-foot Godzilla couldn’t physically exist and reveals the psychological allure of zombies and their connection to human fears. The conversation also touches on the role of monsters in reflecting our own monstrosities and emphasizes how understanding the science behind these creatures can help demystify them.

In this discussion, Bogdan Botezatu, Director of Threat Research at Bitdefender, dives deep into the world of deepfakes and cyber scams. He reveals that global scam losses could reach $1 trillion next year. The conversation explores how deepfakes amplify fraud, with attackers impersonating trusted figures to enhance their schemes. Botezatu also emphasizes that 90% of scams exploit human psychology over technology. He urges vigilance and reporting of scams to aid law enforcement. It's a compelling insight into the war against online deception.
