What is a Black Hole?Core Definition: A black hole is a region of space with an extraordinarily powerful gravitational field created when massive amounts of matter are packed into a tiny volume.The "Divide-by-Zero" Error: In simple terms, a black hole represents a point where our current understanding of physics breaks down—a mathematical singularity where space-time equations result in an undefined state.Event Horizon: The absolute point of no return. Gravity is so strong within the event horizon that not even light can escape, causing its trajectory to loop back inward.Star Collapse & SupernovasSt...

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 in...

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.
