Episodes 13
- Oct 6, 2026 · 1h 0mCosmic ideas meet the limits of observationThe episode shows how evidence, relativity, and statistics separate useful explanations of the universe from seductive but misleading analogies.
- Oct 2, 2026 · 1h 17mKrakauer separates intelligence from capability in the AI ageThe episode asks whether systems that process information at enormous scale are intelligent—or merely powerful, energy-intensive pattern machines.
- Sep 29, 2026 · 54 minString theory tests physics beyond the Standard ModelThe conversation examines whether extra dimensions, hidden gravity, and emerging models of spacetime can turn string theory into testable physics.
- Sep 22, 2026 · 42 minStarTalk turns cosmic science into a chaotic game nightThe episode shows how games, visual design, and playful explanations can make difficult ideas in astronomy and physics memorable.
- Sep 18, 2026 · 59 minCosmic limits reshape what humanity can knowThe episode connects interstellar travel, quantum theory, cosmic expansion, and the future horizon of observation to one question: where does physical knowledge end?
- Sep 15, 2026 · 48 minOluseyi maps the cosmic chain that makes life possibleThe conversation tests how far evidence can carry explanations of existence before speculation outruns what science can establish.
- Sep 8, 2026 · 46 minPhysics explains craters, clocks, and the limits of lifeThe episode connects familiar puzzles about time, impacts, and animal size to the physical laws that constrain Earth and living organisms.
- Sep 1, 2026 · 54 minExoplanets challenge what makes a world habitableThe episode tests how scientists can distinguish real evidence of life from misleading signals across an unexpectedly diverse planetary population.
- Aug 28, 2026 · 52 minAdvanced nuclear faces AI’s surging power demandAI and other emerging technologies are creating demand for reliable clean electricity, forcing a choice between nuclear expansion, alternatives, cost, safety, and deployment speed.
- Aug 25, 2026 · 50 minRoman telescope tests dark energy and searches for new physicsIndependent measurements from Roman and Euclid could clarify whether cosmic acceleration reflects evolving dark energy, modified gravity, or gaps in current physics.
- Aug 21, 2026 · 1h 3mThe brain invents reality from electrical signalsUnderstanding perception as a construction reshapes how we think about memory, agency, hallucinations, time, and consciousness.
- Aug 18, 2026 · 55 minInsects power ecosystems while humans remake their worldThe episode connects insect evolution and ecological importance to mounting pressures from climate change, pollution, habitat loss, and human bias.
