The New Science of Planet Hunting in the Cosmos

The New Science of Planet Hunting in the Cosmos

For thousands of years, humans have wondered whether we’re alone in the cosmos. Now, for the first time, we have the technology to investigate. But once you look for life elsewhere, you realize it is not so simple. How do you find it over cosmic distances? What actually is life?

As founding director of Cornell University’s Carl Sagan Institute, astrophysicist Lisa Kaltenegger has built a team of tenacious scientists from many disciplines to create a specialized toolkit to find life on faraway worlds. In Alien Earths, she demonstrates how we can use our homeworld as a Rosetta Stone, creatively analyzing Earth’s history and its astonishing biosphere to inform this search. With infectious enthusiasm, she takes us on an eye-opening journey to the most unusual exoplanets that have shaken our worldview - planets covered in oceans of lava, lonely wanderers lost in space, and others with more than one sun in their sky! And the best contenders for Alien Earths. We also see the imagined worlds of science fiction and how close they come to reality.

With the James Webb Space Telescope and Dr. Kaltenegger’s pioneering work, she shows that we live in an incredible new epoch of exploration. As our witty and knowledgeable tour guide, Dr. Kaltenegger shows how we discover not merely new continents, like the explorers of old, but whole new worlds circling other stars and how we could spot life there. Worlds from where aliens may even be gazing back at us. What if we’re not alone?

Lisa Kaltenegger is the Director of the Carl Sagan Institute to Search for Life in the Cosmos at Cornell and Associate Professor in Astronomy. She is a pioneer and world-leading expert in modeling potential habitable worlds and their detectable spectral fingerprint. Kaltenegger serves on the National Science Foundation’s Astronomy and Astrophysics Advisory Committee (AAAC), and on NASA senior review of operating missions. She is a Science Team Member of NASA’s TESS Mission as well as the NIRISS instrument on James Webb Space Telescope. Kaltenegger was named one of America’s Young Innovators by Smithsonian magazine, an Innovator to Watch by Time magazine. She appears in the IMAX 3D movie “The Search for Life in Space” and speaks frequently, including at Aspen Ideas Festival, TED Youth, World Science Festival and the Kavli Foundation lecture at the Adler Planetarium.

Shermer and Kaltenegger discuss: Carl Sagan and his influence • Sagan’s Dragon • ECREE Principle • how stars, planets and solar systems form • how exoplanets are discovered • Hubble Space Telescope, Kepler Space Telescope, James Webb Space Telescope • The Origin of Life • Fermi’s Paradox: where is everybody (the Great Silence, the Great Filter) • biosignatures • technosignatures • Dyson spheres • Will aliens be biological or AI? • interstellar travel • Kardashev scale of civilizations • how to talk to aliens when we can’t even talk to dolphins • Deities for Atheists, Skygods for Skeptics: aliens as gods and the search as religion • why alien worlds matter.

What Are We Really Fighting Over? Understanding Outrage Through Moral Psychology

What Are We Really Fighting Over? Understanding Outrage Through Moral Psychology

In this episode, Kurt Gray offers a groundbreaking perspective on the moral mind, challenging the assumption that liberals and conservatives have radically different moral foundations. Drawing on the latest science, he reveals that everyone’s moral judgments stem from feelings of vulnerability to harm. We all care about protecting ourselves and others, but conflict arises when we perceive harm differently. Gray explores how moral outrage is triggered when we disagree about who the “real” victim is, whether in political debates, personal conflicts, or even everyday situations.

How to Start a New Country

How to Start a New Country

It’s clear states, borders, and countries constantly evolve. But how do countries form? And what does it take to start a new one?

Brimen shares insights into the challenges of governance in developing nations, lessons learned from Venezuela’s economic collapse (despite the country having the world’s largest oil reserves), and successful governance models in places like Dubai (a small desert fishing and pearl diving village until the early 1970s) and Hong Kong (under British rule until 1997).

Evidence-Based Charity and Moral Psychology

Evidence-Based Charity and Moral Psychology

In the U.S. alone, more than $400 billion are donated to charity each year—equivalent to two percent of American GDP. This generosity is wonderful, but these gifts don’t do nearly as much good as they could. In recent years, researchers have started studying the effectiveness of different charities, just as investors study the effectiveness of different companies. These researchers ask questions like: How much money does it cost for this charity to save someone’s life? The answers are stunning. Charity experts estimate that the most effective charities are about 100 times more effective than typical charities. For example, you can do more good by donating $100 to a highly effective charity than by donating $10,000 to a typical charity. Shermer and Greene discuss effective altruism, evidence-based philanthropy, and GivingMultiplier’s unique model for maximizing charitable impact. They explore moral judgment theories, from deontology to consequentialism, and delve into complex topics like donor fatigue, public vs. private solutions, abortion, capital punishment, and political polarization. Greene shares practical insights into addressing societal divides and inspiring collective action. Joshua Greene is a Professor of Psychology at Harvard, where he teaches “Evolving Morality: From Primordial Soup to Superintelligent Machines,” one of the university’s most popular courses. He is also the author of Moral Tribes: Emotion, Reason, and the Gap Between Us and Them, which integrates moral philosophy, psychology, and neuroscience to explain the underlying causes of modern conflict. Josh’s latest applied research has led to novel, evidence-based strategies for reducing political animosity and inspiring thousands of people to support nonprofits addressing extreme poverty, climate change, and other pressing societal issues. His new organization is GivingMultiplier.org.

Building a Wealthier, Fairer Society

Building a Wealthier, Fairer Society

Historically, Western societies were defined by stark divisions between wealth and poverty, with only a slim middle class. Today, the economic landscape has transformed, largely through political and institutional changes that have enabled wealth distribution and middle-class growth. Economist Daniel Waldenström explores this evolution, highlighting that effective social and tax policies are essential to advancing shared prosperity without undermining entrepreneurship. Using rigorous research, Waldenström’s work demonstrates how wealth accumulation patterns have shifted since the 1800s, emphasizing the significant role of increased access to education, property ownership, and pensions. His insights advocate for policies that promote wealth creation across all social tiers, ensuring sustainable growth and financial security for future generations. Shermer and Waldenström cover the scientific basis of economics, how personal beliefs shape economic theories, and differences between income and wealth inequality. They delve into historical wealth disparities, factors that have driven middle-class growth, and policies like the Laffer Curve and labor taxation. Waldenström also offers practical advice on fiscal policy and strategies to help poorer nations achieve wealth and stability.

Gareth Gore Investigates: Opus Dei, Dark Money, and Global Deception

Banco Popular, once a top global bank, collapsed unexpectedly in 2017. Investigative journalist Gareth Gore initially expected to find another case of capitalist greed, but instead uncovered a web of deception orchestrated by men linked to Opus Dei. Gore’s investigation revealed decades of hidden corruption, with Opus Dei using its control over the bank to amass wealth and spread its influence. Using access to insider accounts and bank records, Gore exposed how Opus Dei recruited vulnerable individuals—often children—into lives of servitude. His findings also unveiled Opus Dei’s financial ties to far-right movements, including its role in overturning Roe v. Wade, raising important questions about the forces shaping modern society. Shermer and Gore discuss Opus Dei’s role in the collapse of Banco Popular, its influence in politics, and the group’s history. They explore Opus Dei’s abusive practices, financial power, and efforts to spread its agenda, including through human trafficking and infiltration of institutions.
