It’s a big cosmos out there. It wasn’t too long ago that we couldn’t be sure that any planets existed anywhere outside of our own solar system. But in just the past handful of years, we’ve learned that planets orbiting stars are the rule, not the exception, which suggests that there may be 200 billion planets just in our galaxy alone, and trillions upon trillions of planets throughout the known universe. Surely, many of the planets in the Milky Way must be home to life forms, and even technologically advanced civilizations. So where the heck are they? Why can’t we find them? Why won’t they talk to us? Would we even know it if they did? To talk about the prospects for life on other worlds, intelligent and otherwise, Point of Inquiry host Paul Fidalgo talks to journalist Lee Billings. Lee is a reporter and editor for Scientific American covering space and physics, as well as the author of Five Billion Years of Solitude: The Search for Life Among the Stars. Billings explains how this quest, the search for extraterrestrial intelligence, has become increasingly daunting even as our knowledge of the cosmos grows richer. It is a quest rife with […]
Launched in 2005, Point of Inquiry is the premier podcast of the Center for Inquiry. Point of Inquiry critically examines topics in science, religion, philosophy, and politics.
Each episode takes on a specific issue and features lively discussion with leading scientists, researchers and writers.
The modern conception of secular humanism arose in large part as a response to the horrors of Nazism and the Holocaust, and the evils of racism and bigotry. Humanist Manifesto II, written in 1973, called for “the elimination of all discrimination based upon race, religion, sex, age, or national origin,” and envisioned a world in which all human beings were given equal dignity within a global community. It is now two weeks since newly emboldened white supremacists, including Nazis and Ku Klux Klansmen, marched on Charlottesville, attacked counter-protesters, and murdered Heather Heyer. President Trump has exacerbated the ensuing tension and fear by refusing to assign full responsibility to the white supremacists, and insisting that the blame be shared by some contingent of an alleged “alt-left.” It is time for humanism to respond once again. Our guest for this episode of Point of Inquiry is James Croft of the St. Louis Ethical Society, who encourages us to fully live out the values of humanism, not just as an academic philosophy but as an urgent call to act on behalf of others. “Be not restrained,” he advises, as he and host Paul Fidalgo discuss how humanists can lead the way in healing […]
The U.S. space program is both beloved and neglected. It brings us breathtaking pictures from distant worlds and drives the human species to push itself farther out into the cosmos. But at the same time, it is subject to terrestrial political concerns, and without the urgency of a Cold War-era “moonshot” to galvanize the public’s enthusiasm, U.S. space policy is at times directionless, and always underfunded. To talk about the state of space exploration, Point of Inquiry host Paul Fidalgo talks to Loren Grush, space reporter for The Verge, and previously of Popular Science. They discuss space policy in the Trump era, the challenges NASA faces to realize its ambitions, the grand promises of the private space industry, the prospects and perils for a human mission to Mars, the hostility women continue to face within the space community, and much more. Oh, and we’ll also find out what it was that Mike Pence touched at the Kennedy Space Center that he was told not to touch.

We want to believe that climate change can be stopped, that humanity can summon the political will to take decisive and meaningful action to avert disaster and save civilization. But the difficult reality is that even if we make our very best efforts to rein in greenhouse gas emissions, climate change is coming. The real question now is how bad are we going to allow it to get? There is perhaps no one better suited to discuss humanity’s unwitting impact on the planet than this episode’s guest, Elizabeth Kolbert. As the Pulitzer Prize-winning author of The Sixth Extinction: An Unnatural History and as a staff writer at The New Yorker she has chronicled the agonizing but undeniable realities of the ecological damage wrought by humans and the complicated politics of confronting — or ignoring — that damage. Kolbert talks to Point of Inquiry host Paul Fidalgo about how we as a society and as individuals think and talk about climate change and the inevitable environmental and political disruptions to come. BONUS FEATURE: Point of Inquiry bids a fond farewell to Nora Hurley, the show’s producer since 2014, with a kind of “exit interview.” Nora and Paul discuss what’s next for her, as […]
On June 1, President Donald Trump declared that he was withdrawing the United States from the Paris climate accord, an international agreement meant to significantly reduce greenhouse gas emissions and limit the global average temperature increase to no more than 2 degrees Celsius. For those who accept the reality of the threat posed by climate change, the news has sparked a good deal of anger, outrage, and not a small amount of despair for the fate of our planet. Despair not, says our guest, Carl Pope, the former Executive Director of the Sierra Club, and the co-author of the optimistic new book Climate of Hope: How Cities, Businesses and Citizens Can Save the Planet, co-written with former New York City Mayor Michael Bloomberg. In a timely conversation with Point of Inquiry’s new host Paul Fidalgo (in his first episode as host!), Pope rejects doomsday attitudes about global warming, insisting that the window to stop climate change has not closed. He’ll tell us why he’s so optimistic, and what he thinks about the president’s decision to reject the Paris accord. About the “Point of Inquiry” Podcast
