Asteroids are rich in precious metals and other valuable resources. But mining them presents considerable challenges. We discuss these, and consider how these spinning, rocky resources might be the key to a space-faring future. But an economist points out the consequences of bringing material back to Earth, and a scientist raises an ethical question; do we have an obligation to keep the asteroids intact for science?  Guests: Jim Bell - Planetary scientist in the School of Earth and Space Exploration at Arizona State University. Martin Elvis - Astronomer and author of “Asteroids: How Love, Fear, and Greed Will Determine Our Future in Space.” Ian Lange - Economist and associate professor at the Colorado School of Mines and author of a paper on the feasibility of asteroid mining.

A century ago, British archaeologist Howard Carter opened the only surviving intact tomb from ancient Egypt. Inside was the mummy of the boy king Tutankhamun, together with “wonderful things” including a solid gold mask. Treasure from King Tut’s crypt has been viewed both in person and virtually by many people since. We ask what about Egyptian civilization so captivates us, thousands of years later. Also, how new technology from modern physics allows researchers to “X-Ray” the pyramids to find hidden chambers.

By one estimate the average American home has 300,000 objects. Yet our ancient ancestors had no more than what they could carry with them. How did we go from being self-sufficient primates to nonstop shoppers? We examine the evolutionary history of stuff through the lens of archeology beginning with the ancestor who first picked up a palm-sized rock and made it into a tool. Guest: Chip Colwell - archeologist and former Curator of Anthropology at the Denver Museum of Nature & Science, editor-in-chief of the digital magazine Sapiens, and author of “So Much Stuff: How Humans Discovered Tools, Invented Meaning, and Made More of Everything.” Featuring music by Dewey Dellay and Jun Miyake You can get early access to ad-free versions of every episode by joining us on Patreon.

You are getting sleeeepy and open to suggestion. But is that how hypnotism works? And does it really open up a portal to the unconscious mind? Hypnotism can be an effective therapeutic tool, and some scientists suggest replacing opioids with hypnosis for pain relief. And yet, the performance aspect of hypnotism often seems at odds with the idea of it being an effective treatment.  In our regular look at critical thinking, Skeptic Check, we ask what part of hypnotism is real and what is an illusion. Plus, we discuss how the swinging watch became hypnotism’s irksome trademark.

With planets and moons, it’s what’s inside that counts. If we want to understand surface features, like volcanoes, or their history, such as how the planet formed or whether it’s suitable for life, we study their interiors. Astronomer Sabine Stanley takes us on a journey to the centers of Venus, Saturn’s large moon Titan, Jupiter’s moon Io, and of course Earth, to help us understand how they, and the solar system, came to be.  Guest: Sabine Stanley - Planetary scientist at Johns Hopkins University and the author of What’s Hidden Inside Planets.

Worried that AI will replace you? It may not seem like the Hollywood writers’ strike has anything in common with the Luddite rebellion in England in 1811, but they are surprisingly similar. Today we use the term “Luddite” dismissively to describe a technophobe, but the original Luddites – cloth workers – organized and fought Industrial Revolution automation and the factory bosses who were replacing humans with cotton spinning machines and steam powered looms. Find out what our age of AI can learn from textile workers of 200 years ago about keeping humans in the loop.

By one estimate we spend a fifth of our lives watching movies or TV. In fact, we consume entertainment almost as habitually as we eat or sleep, activities that receive scientific scrutiny and study. So why not consider the effects that watching movies and TV have on our minds and bodies too? When we do, we find that they are not mere escapism. A data scientist reveals why we are what we watch, and how scientists and filmmakers work, often with competing agendas, to create sci-fi entertainment.

Maybe you don’t remember the days of the earliest coal-fired stoves. They changed domestic life, and that changed society. We take you back to that era, and to millennia prior when iron was first smelt, and even earlier, when axe-handles were first fashioned from wood, as we explore how three essential materials profoundly transformed society.  We were once excited about coal’s promise to provide cheap energy, and how iron would lead to indestructible bridges, ships, and buildings. But they also caused some unintended problems: destruction of forests, greenhouse gases and corrosion. Did we foresee where the use of wood, coal, and iron would lead? What lessons do they offer for our future? Guests: Jonathan Waldman – Author of Rust: The Longest War. Ruth Goodman – Historian of British social customs, presenter of a number of BBC television series, including Tudor Monastery Farm, and the author of The Domestic Revolution: How the Introduction of Coal into Victorian Homes Changed Everything.

Nothing lasts forever. Even the universe has several possible endings. Will there be a dramatic Big Rip or a Big Chill­–also known as the heat death of the universe–in trillions of years? Or will vacuum decay, which could theoretically happen at any moment, do us in? Perhaps the death of a tiny particle – the proton – will bring about the end. We contemplate big picture endings in this episode, and whether one could be brought about by our own machine creations.  Guests:  Anders Sandberg – Researcher at the Future of Humanity Institute at the University of Oxford Katie Mack – Assistant professor of physics at North Carolina State University, and the author of “The End of Everything, Astrophysically Speaking.” Brian Greene – Brian Greene, professor of physics and mathematics at Columbia, and author of “Until the End of Time: Mind, Matter, and Our Search for Meaning in an Evolving Universe” Originally aired May 3, 2021 Featuring music by Dewey Dellay and Jun Miyake Big Picture Science is part of the Airwave Media podcast network. Please contact advertising@airwavemedia.com to inquire about advertising on Big Picture Science.

The world is a colorful place, and human eyes have evolved to take it in – from vermillion red to bright tangerine to cobalt blue. But when we do, are you and I seeing the same thing?  Find out why color perception is a trick of the brain, and why you and I may not see the same shade of green. Or blue. Or red. Also, platypuses and the growing club of fluorescent mammals, and the first new blue pigment in more than two centuries.   Guests: Paula Anich – Associate Professor of Natural Resources, Northland College Michaela Carlson – Assistant Professor of Chemistry, Northland College Rob DeSalle – Curator at the American Museum of Natural History, and co-author of “A Natural History of Color: the Science Behind What We See and How We See It” Mas Subramanian – Professor of Materials Science at Oregon State University originally aired March 8, 2021 Featuring music by Dewey Dellay and Jun Miyake Big Picture Science is part of the Airwave Media podcast network. Please contact advertising@airwavemedia.com to inquire about advertising on Big Picture Science.

T-Rex is having an identity crisis. Rocking the world of paleontology is the claim that Rex was not one species, but actually three. It’s not the first time that this particular dino has forced us to revise our understanding of the past. The discovery of the first T-Rex fossil in the 19th century taught humanity a scary lesson: species eventually go extinct. If it happened to this seemingly invincible apex predator, it could happen to us too. Hear how the amateur fossil hunter Barnum Brown’s discovery of T-Rex changed our understanding of ourselves, and the epilogue to the dinosaur era: how our mammalian relatives survived the potential extinction bottleneck of an asteroid impact. Guests: Thomas Carr - Vertebrate paleontologist and Professor of Biology, Carthage College Peter Makovicky - Vertebrate paleontologist and Professor of paleontology in the Department of Earth and Environmental Sciences at the University of Minnesota David Randall - Author of “The Monster’s Bones: The Discovery of T Rex and How It Shook Our World” Steve Brusatte - Personal Chair of Paleontology and Evolution, University of Edinburgh.
