Is It Actually Possible to Bring Back Dinosaurs? Unearthing Ancient DNA, CRISPR, Chaos Theory in Jurassic Park with Astrobiologist Betül Kaçar
Saison 1 · Épisode 103
mardi 2 juin 2026 • Durée 31:05
In this episode of Unobtainium Podcast, hosts Adam Sigel and Amy Mainzer are joined by astrobiologist and evolutionary scientist Betül Kaçar to explore the real science beneath Jurassic Park. Could dinosaur DNA really survive inside amber for 65 million years? How close are modern scientists to resurrecting extinct species? And what happens when humanity gains the power to rewrite life itself? The conversation dives into cloning, CRISPR gene editing, ancient DNA, microbial evolution, extinction events, and the surprising role bacteria played in transforming Earth’s atmosphere billions of years ago. Along the way, the episode explores the deeper themes that make the Jurassic Park films endure: scientific ambition, chaos theory, corporate greed, the ethics of de-extinction, and humanity’s endless desire to control nature — even when nature refuses to cooperate. Equal parts funny, philosophical, and scientifically grounded, the discussion reveals why Jurassic Park remains one of the most compelling science fiction franchises.
What Is the Science of Time Travel? In their first episode, Amy and Adam Go “Back to the Future” on Einstein, Paradoxes, and an Iconic DeLorean with a Flux Capacitor
Saison 1 · Épisode 101
mardi 26 mai 2026 • Durée 29:57
What if the greatest time travel device in movie history is just a glowing Y-shaped excuse to ask bigger questions about science, storytelling, and human imagination?
In the premiere episode of Unobtainium Podcast, Hollywood writer/producer Adam Sigel and rocket scientist Amy Mainzer launch a smart, funny deep dive into the science of science fiction through one of cinema’s most iconic inventions: the flux capacitor from Back to the Future.
Along the way, they explore why great sci-fi doesn’t need perfect science — it just needs enough “unobtainium” to make us believe. From Einstein’s theory of relativity and real-world time dilation to wormholes, paradoxes, plutonium, and the narrative genius of a time-traveling DeLorean, the conversation moves between real physics and Hollywood storytelling craft.
The result is a lively exploration of why science fiction matters: not just because it predicts the future, but because it helps us imagine it.
Lucid Dreaming Is Real, but Is Shared Dreaming Also Possible? David Eagleman Discusses Neuroscience of Dreams, Memory, Consciousness in Christopher Nolan's Inception
Saison 1 · Épisode 102
mardi 26 mai 2026 • Durée 39:06
In this mind-bending episode of Unobtainium Podcast, hosts Adam and Amy are joined by neuroscientist and bestselling author David Eagleman to unpack the science behind Inception. They explore what dreams actually are, why the brain creates them, and whether concepts like dream manipulation, shared dreaming, mind hacking, and incepting your subconscious could ever become real. The conversation moves from the neuroscience of memory and perception to lucid dreaming and recurring nightmares.
Also, they touch on related issues such as false memories, eyewitness testimony, processing grief, and the unsettling idea that our brains constantly rewrite reality. Along the way, they examine how Christopher Nolan’s film turns neuroscience into cinematic storytelling — using dreams not just as a sci-fi premise, but as a metaphor for filmmaking itself: the act of planting ideas inside someone else’s mind. The result is a fascinating exploration of consciousness, imagination, and why the line between reality and perception may be thinner than we think.

In this episode of Unobtainium Podcast, hosts Adam and Amy sit down with astrophysicist Neil deGrasse Tyson to unpack the science and mythology of Star Wars. Together, they explore whether the Force resembles anything in real-world physics, from gravity and electromagnetism to quantum mechanics and multiple dimensions. The conversation dives into hyperspace travel, wormholes, faster-than-light storytelling shortcuts, and the infamous“12 parsecs” controversy, while also examining why Star Wars resonates so deeply on a human level. Along the way, they discuss the Star Wars canon, good versus evil, selflessness versus selfishness, the psychology of belief, and why the Force endures as a timeless metaphor for power, destiny, and transformation. Funny, philosophical, and deeply nerdy, the episode explores why Star Wars continues to shape modern culture nearly 50 years after its release.
Is a “Severance” Split Brain possible? How Are Memories Formed? Can Different Aspects of Personality Be Isolated Inside the Brain? Memory, Identity, and Neuroplasticity with David Eagleman
Saison 1 · Épisode 110
mardi 21 juillet 2026 • Durée 44:50
Could your mind really be split in two? Can a chip in your brain divide your work life from your personal life?
Hosts astrophysicist and UCLA Professor Dr. Amy Mainzer and writer/producer Adam Sigel welcome back Stanford neuroscientist, author and creator of Inner Cosmos, David Eagleman, who also serves as a science consultant for Severance Season 3. Adam references the Hollywood development term "science-faction" to describe the show—a blend of fiction rooted heavily in real-world scientific possibilities. The core premise of the show explores the ultimate, extreme form of satirical work-life balance: surgically separating an individual's memories between their corporate life ("innies") and personal life ("outies").
How the Brain Processes Memory
To understand how a "severance chip" might function, Dr. Eagleman breaks down the fundamental mechanics of the human brain:
The Electrochemical System: The roughly 86 billion neurons in the brain fire electrical signals down axons, releasing chemicals to interact with neighboring cells.
Associative Neural Networks: Unlike computers, human memory functions as an interconnected web. Hearing a single word instantly triggers a vast, non-linear network of related memories, experiences, and references.
The Coalition of Memories: Debunking the "Grandmother Cell" (the idea that a single neuron holds a specific memory), memories are actually distributed across vast coalitions of millions of interconnected neurons working in unison.
The Mechanics of a "Severance Chip"
Dr. Eagleman, who consulted on the science for Severance Season 3, proposes a real-world hypothesis for how the fictional procedure could work. Rather than physically cutting parts of the brain, the chip would act as an electrical coding switch:
Mining on the Moon? Explore the possibilities of Fusion Using Helium-3, a New AI Computer in Space, and the Ethics of Reaching Humanity's Next Frontier with Lunar Expert Dave Paige
Saison 1 · Épisode 109
mardi 14 juillet 2026 • Durée 42:11
Is the 2009 movie Moon pure fiction, or is lunar mining the future of clean energy? Could automated harvesters actually strip-mine the lunar surface regolith (moon soil)? Could we really harvest enough helium-3 to power nuclear fusion reactors on Earth? Is it possible to build a permanent moon base via NASA's Artemis missions?
In this episode of the Unobtainium podcast, hosts astrophysicist and UCLA Professor Dr. Amy Mainzer and writer/producer Adam Sigel dive into a fascinating Moon movie breakdown. Directed by Duncan Jones (David Bowie’s son) on a modest $5 million budget, the outstanding 2009 Moon is widely celebrated as one of the best hard science fiction movies in the last 20 years. To separate cinematic fiction from orbital reality, the hosts are joined by a leading lunar and Mars expert: Dr. Dave Paige from UCLA’s Department of Earth, Planetary, and Space Sciences.
The Reality of Lunar Mining and Helium-3 Fusion
The central conceit of Moon revolves around a massive industrial operation by Lunar Industries to harvest helium-3 from the Moon’s surface to power clean nuclear fusion back on Earth. Dr. Paige suggests that mining the Moon at an industrial scale introduces massive economic and physical hurdles. Unlike nuclear fission (which splits heavy atoms), nuclear fusion jams light atoms together to release an immense amount of energy. While the movie positions helium-3 as an easily fusible miracle isotope that offers an "aneutronic" reaction (meaning it doesn't emit destructive neutrons), Dr. Paige points out a major real-world catch: a helium-3 reaction actually requires temperatures five times higher than standard hydrogen isotopes—billions of degrees Celsius—making it incredibly difficult to harness.
Scraping the Lunar Regolith: A Scarred Moon?
Helium-3 is an ultra-rare primordial isotope created just 20 seconds after the Big Bang. While it is virtually non-existent on Earth, it has accumulated for billions of years in the lunar regolith (lunar soil) via the solar wind. Because the Moon lacks plate tectonics and a traditional atmosphere, its ancient surface acts as perfect "flypaper" for cosmic particles. However, harvesting it requires an astonishingly inefficient scale. To extract just one single gram of helium-3, automated lunar harvesters would need to excavate and heat 100 tons of lunar soil to a glowing 600°C. Dr. Paige calculates that providing enough helium-3 to power 75% of Earth would require strip-mining a patch of the moon the size of a small U.S. state annually—an operation that would permanently change the face of the moon visible from Earth within a few centuries.

What makes the deep-space horror classic film Alien (1979) one of the scariest science fiction movies ever made? Amy and Adam explore science, psychology, and the enduring power of Ridley Scott’s masterpiece. In space, no one can hear you scream—but there’s plenty to talk about.
Full Summary
In this episode of the Unobtainium podcast, astrophysicist and planetary scientist Dr. Amy Mainzer (UCLA) and Hollywood writer-producer Adam Sigel break down Ridley Scott’s 1979 cinematic masterpiece, Alien in search of an answer to why this movie is one of the most terrifying sci-fi horror movies of all time. The hosts shift the lens to explore how the film grounds its cosmic dread in real-world evolutionary biology, planetary science, and a dash of quantum physics.
The Hollywood Tropes of Space Travel: Cryosleep and Faster-Than-Light Travel
The discussion kicks off with some quick math and a hint that the Nostromo navigates near the real star system Zeta Reticuli, located 37 light-years from Earth. In the film, the crew will travel this distance in just ten months, meaning they are moving at roughly 44 times the speed of light. Dr. Mainzer notes that while true faster-than-light travel is impossible under current scientific paradigms, the film cleverly suggests a quantum physics loophole involving theoretical particles called tachyons. The hosts also debate the practical limits of cryogenic sleep (hypersleep), noting that its inclusion adds a gritty, unglamorous layer of authenticity to space exploration.
The Search for Exoplanets and Extraterrestrial Life
As a planetary scientist, Amy bridges the gap between Hollywood fiction and modern astronomy. She reveals that over the last two decades, space telescopes like the Kepler mission have proven that nearly every star in the night sky hosts its own solar system. However, most known exoplanets discovered so far are hostile gas giants (like Jupiter or Saturn) or "super-Earths" lacking evidence of liquid water or breathable oxygen atmospheres. This reality highlights the terrifying mystery of : what kind of extreme environment would it take to naturally evolve a perfect apex predator?

But the episode also digs into the film's deeper themes: postwar trauma, guilt, sacrifice, resilience, and humanity's complicated relationship with powerful technologies. The result is a fascinating look at how a giant radioactive lizard (or maybe a wayward dinosaur?) became cinema's most enduring metaphor for the atomic age. And why Godzilla Minus One resonated with audiences around the world.
From the history of postwar Japan to the cutting-edge future of clean energy, they’re unpacking it all!
Full Symmary
What makes Godzilla such an enduring pop culture icon? Godzilla Minus One took the world by storm, returning the King of Monsters to his terrifying roots as a symbol of nuclear destruction while delivering a deeply human story about trauma, survivor's guilt, and rebuilding after World War II.
In this episode of Unobtainium, Adam and Amy dive into the Godzilla science, history, and emotional power of the film with , a nuclear engineer and professor of Engineering Physics at the University of Wisconsin–Madison. They break down the realities of including the fundamental differences between , how real-world nuclear reactors work, and whether Godzilla's devastating atomic breath is scientifically closer to a fission reactor or fusion reactions (hint: the blue color tells a lot).
Can Robots Feel? Roboticist Hiro Ono joins us to explore consciousness, mortality, AI Robots, and what it means to be human as we discuss Ridley Scott’s thought-provoking sci-fi film Blade Runner.
Saison 1 · Épisode 106
mardi 23 juin 2026 • Durée 39:29
Episode Description
Blade Runner is famous for its flying cars, neon cyberpunk skylines, and bioengineered replicants—but its most enduring questions are about what it means to be human. In this episode of the Unobtainium podcast, hosts Adam and Amy are joined by renowned roboticist Hiro Ono to explore the cutting-edge science and philosophy behind Ridley Scott's sci-fi masterpiece.
How close is modern technology to creating truly humanoid robots? Can Artificial General Intelligence (AGI) or large language models (LLMs) achieve actual machine consciousness? What role do memory, emotion, and mortality play in shaping identity? From artificial intelligence and robotics to Roy Batty's famous "Tears in Rain" monologue, this conversation examines why Blade Runner remains the ultimate exploration of what it means to be human—and why its warnings feel more relevant in today's era of generative AI than ever before.
Full Episode Summary
What makes us human? More than forty years after its release, Blade Runner (1982) remains one of the most influential and thought-provoking science fiction films ever made. Ridley Scott's cyberpunk Neo-Noir masterpiece continues to trend today, shaping critical conversations around artificial intelligence, advanced robotics, consciousness, memory, identity, and the future relationship between humans and machines.
In this episode of Unobtainium, Adam and Amy sit down with roboticist Hiro Ono (Georgia Tech, formerly NASA Jet Propulsion Laboratory) to explore the real-world science behind Blade Runner, its iconic replicants, and the core themes first posed by Philip K. Dick's novel, Do Androids Dream of Electric Sheep?
An implanted chip applies a distinct electrical code to the employee's active thoughts at work. The neurons marked with this specific "work code" only connect with a other work-tagged neurons, stopping their neural pathways from interacting. The show's elevator completely flushes active electrical patterns in the brain's short-term memory.
Split-Brains and Multiple Identities
The conversation shifts to historical precedents and the psychological toll of memory separation: Split-Brain Surgery (1960s treatment for severe epilepsy) is the severing the corpus callosum, the neural superhighway linking the brain's hemispheres which creates two separate consciousnesses in one body (sometimes causing Alien Hand Syndrome, where hands physically work against each other). Distributed Memory (The Ngram) says memories are not stored in a single, hard-drive-like location but are distributed holographically across the brain, providing evolutionary redundancy. Long-term memory is divided into separate, distinct networks and amnesia cases (such as Ansel Bourne or Jodie Roberts) demonstrate that someone can lose their autobiographical memory while keeping procedural skills.
Philosophical Implications: Who Are We?
Ultimately, Severance serves as a profound philosophical sandbox. Because human identity is entirely shaped by the sum of our accumulated memories, creating isolated memory pools effectively creates two distinct, living people inside one body. This separation poses a tragic human dilemma, exemplified by the main character, Mark, who uses the procedure to escape the heavy burden of grief over his deceased wife. While it successfully blocks his suffering for eight hours a day, it forces audiences to grapple with a haunting question: If you could wipe away your deepest suffering at the cost of your memories and your true identity, would you?
Redefining the Sci-Fi Tropes: Space Isolation and AI
Beyond the planetary geology, the Unobtainium team explores the intense human drama of the film's lone worker, Sam Bell, who is on a grueling three-year contract. The hosts note that real-world space agencies, such as NASA, use strict "buddy systems" for long-duration spaceflight to safeguard mental health. They also highlight how the film brilliantly subverts the classic "malevolent AI" trope popularized by HAL 9000 in 2001: A Space Odyssey. Instead of acting as a cold, corporate antagonist, the ship's AI, Gertie, eventually demonstrates genuine compassion. It shifts the film from a standard space thriller into a profound existential commentary on corporate greed, scientific ethics, and what it truly means to be human.
One of the most fascinating aspects of this Alien movie analysis is the biological inspiration behind the creature. Amy and Adam point out that the horrifying xenomorph life cycle—where a parasitic organism implants an egg into a living host, which is ultimately destroyed during birth—is deeply rooted in terrestrial nature. The hosts draw direct evolutionary parallels to the tarantula hawk wasp, a real insect that paralyzes its prey, lays an egg inside it, and allows its larva to consume the host from the inside out.
The Real Monster: Corporate Greed and AI Corruption
Beyond the creature's acid blood and phallic, H.R. Giger-designed aesthetic, Unobtainium unpacks the film’s deeper subtexts. Unlike the optimistic, utopian futures of Star Trek or Star Wars, Alien presents a cynical, dystopian vision of space travel driven entirely by commercial interest and resource extraction. The hosts argue that the true antagonist isn't the creature itself, but rather the faceless Weyland-Yutani corporation. This corporate entity is perfectly represented by the corrupted science officer Ash (a synthetic android) and the ship’s artificial intelligence, "Mother"—both of whom view human life as completely disposable in the pursuit of a bioweapon.
By blending cinematic history with cutting-edge astrobiology, this episode reveals why Alien remains a towering achievement in science fiction horror.
The conversation goes deep into the real science behind Godzilla's radioactive origins, including the differences between ionizing and non-ionizing radiation, how nuclear reactors work, and why fusion energy remains one of humanity's greatest technological challenges. Along the way, Stephanie explains the workings of a reactor, from control rods to Cherenkov radiation, and fusion experiments. And how the world has moved beyond the fear of nuclear weapons to look at how nuclear technology is used for clean energy solutions, medical treatments, and space exploration. And they also touch on the challenges of modern science communication.
But the episode goes far beyond monster science. Amy, Adam, and Stephanie examine the historical context that gave birth to Godzilla in postwar Japan, the legacy of Hiroshima and Nagasaki, the promise and peril of nuclear technology, and the role of science diplomacy in addressing global challenges. They also discuss why Godzilla Minus One resonates so powerfully with audiences today: beneath the spectacle of a giant radioactive monster lies a moving story about family, sacrifice, resilience, and the value of human life.
Topics include: Godzilla Minus One, radiation, nuclear weapons, fission, fusion, reactor design, atomic breath, Cherenkov radiation, clean energy, science communication, postwar Japan, nuclear ethics, science diplomacy, and why one giant monster continues to embody humanity's hopes and fears about technology.
How close are modern autonomous systems and machine learning models to the human-like replicants imagined in the film? Could true Artificial General Intelligence (AGI) ever emerge from neural networks? Together, the hosts and Hiro dive into whether an advanced machine can possess true sentience, or if it is simply simulating human behavior. If memories can be implanted, edited, or manufactured by code, what does that mean for personal identity?
Drawing on his background developing autonomous systems for space exploration and Mars rovers, Hiro explains the current state of robotics technology, machine learning algorithms, and the future of AI. The conversation tackles major scientific hurdles, including:
The "hard problem" of consciousness and qualia.
Emotion, neuroscience, and memory formation.
The ultimate question in tech: Can a machine ever have a subjective experience?
Why Blade Runner Matters in the Age of ChatGPT
The hosts also unpack why Blade Runner is widely considered one of the best sci-fi movies of all time. They discuss the ethics of synthetic humans, AI ethics, robot rights, and the growing societal fear that tech may someday blur the line between artificial and human intelligence. Along the way, they break down the "Tears in Rain" monologue and why Roy Batty's final moments remain cinema's most powerful meditation on mortality, free will, and meaning.
Whether you are looking for a deep Blade Runner explanation, researching AI consciousness, or fascinated by the philosophy of mind, this episode explores the enduring questions at the intersection of science fiction and modern AI research.
