Evidence of Aliens? Harvard Astronomer Avi Loeb

Evidence of Aliens? Harvard Astronomer Avi Loeb

Did Harvard astronomer Avi Loeb discover the remnants of an interstellar meteor in the form of spherules on the ocean floor? Could they be of alien origin?

In today’s special edition of The Michael Shermer Show the guest, Harvard astrophysicist Dr. Avi Loeb announces that he has discovered material from a large interstellar object from the bottom of the Pacific Ocean near Papua New Guinea in an expedition he led over the summer. The object, which he labels IM1—Interstellar Meteor 1—collided with Earth nearly a decade ago and was tracked by U.S. government satellites, which gave Loeb and his team coordinates of where to look. Most of the meteor burned up in the atmosphere but tiny spherules remained on the ocean bottom, which Loeb retrieved and had analyzed in labs at Harvard, UC Berkeley, and the Broker Corporation. These spherules are tiny—smaller than a grain of sand—and there are literally trillions of them around the world of both terrestrial and extraterrestrial origin, so whether or not these particular spherules are Interstellar in origin remains to be seen, despite Loeb’s confidence that they are. Here is what he announced today in a press release:

The Interstellar Expedition of June 2023–led by the expedition’s Chief Scientist, Harvard University Astrophysicist Avi Loeb and coordinated by Expedition Leader Rob McCallum of EYOS Expeditions retrieved hundreds of metallic spheres thought to be unmatched to any existing alloys in our solar system from the seafloor in the Pacific Ocean near Papua New Guinea. Early analysis shows that some spherules from the meteor path contain extremely high abundances of Beryllium, Lanthanum and Uranium, labeled as a never-seen-before “BeLaU” composition. These spherules also exhibit iron isotope ratios unlike those found on Earth, the Moon and Mars, altogether implying an interstellar origin. The loss of volatile elements is consistent with IM1’s airburst in the Earth’s atmosphere. “The “BeLaU” composition is tantalizingly different by factors of hundreds from solar system materials, with beryllium production through spallation of heavier nuclei by cosmic-rays flagging interstellar travel,” says Avi Loeb.

The press release of August 29, 2023 was timed with the publication date of Dr. Loeb’s new book, Interstellar, whose subtitle hints at the scientist’s larger ambitions: The Search for Extraterrestrial Life and Our Future in the Stars.

Dr. Loeb’s co-authored paper has not been peer reviewed. In fact, none of the world’s leading experts on spherules from space have even seen any of Dr. Loeb’s evidence. So in preparation for this episode, I contacted Peter Brown, an astronomer at Western University, Ontario, who specializes in the physics of meteors, and he directed me to the five leading experts in the world on spherules. These include: George Flynn, SUNY, Plattsburgh; Don Brownlee, University of Washington; John Bradley, University of Hawaii; Michael Zolensky, NASA; and Matthew Genge, Imperial College, London. I also consulted Steven Desch, from Arizona State University, as he has been quoted elsewhere as a critic of Avi Loeb’s research. All expressed their skepticism about Dr. Loeb’s findings, which I read on air to Avi to get his response. (See the show notes for this episode on skeptic.com.) Listen to the experts and Dr. Loeb’s response to their skepticism in this episode. (Note: Steven Desch’s initial statement, included in the show notes, was so negative that I chose not to read it on air, but include it in the show notes on skeptic.com for full disclosure of what he thinks about this research. I also included Dr. Desch’s additional comments on why many scientists are skeptical of the U.S. government data on the meteor’s trajectory and impact site.)

I should note that I am a member of the Galileo Project team, which organized this expedition, and I consider Avi a friend and colleague who always welcomes my skepticism in our weekly team meetings. To that end let me emphasize that he is not claiming to have discovered alien technology, only the remnants of an interstellar object. Unfortunately, the media coverage surrounding the Galileo Project in general and this expedition in particular is only interested in whether or not we have made contact with ET. We have not, and Avi is not claiming that we have.

No matter the scientific find is, the media reports it as aliens, aliens, and aliens. Alas.

My own view is that aliens are very likely out there somewhere—given the astronomical numbers of hundreds of billions of galaxies, each of which has hundreds of billions of stars, each of which has planets it seems highly unlikely that we’re alone in the cosmos—but that they have very likely not come here in any shape or form—nonhuman biologics or extraterrestrial metalogics (my own neologism echoing government whistleblower David Grusch’s ridiculous description of alien pilots as “nonhuman biologics” in his Congressional testimony). The universe is vast and consists of mostly empty space. The odds are very long indeed that anyone could find us, much less leave traces for us to evaluate. But in keeping with Cromwell’s Rule in Bayesian reasoning (never assign a 0 or 1 probability to anything because, as Oliver Cromwell famously said, “I beseech you in the bowels of Christ you might be mistaken”), we should keep an open mind and keep looking. That is why I support the SETI program and am on the Galileo Project team. The odds are long but the payoff would be spectacular if we ever did discover extraterrestrial intelligence or the technological artifacts of an extraterrestrial civilization.

Abraham (Avi) Loeb is the Frank B. Baird, Jr., Professor of Science at Harvard University, the longest-serving chair of Harvard’s Department of Astronomy, the founding director of Harvard’s Black Hole Initiative, and the current director of the Institute for Theory and Computation (ITC) within the Harvard-Smithsonian Center for Astrophysics. He also heads the Galileo Project, chairs the Advisory Committee for the Breakthrough Starshot Initiative, and is former chair of the Board on Physics and Astronomy of the National Academies. Author of eight books and more than a thousand scientific papers, Loeb is an elected fellow of the American Academy of Arts and Sciences, the American Physical Society, and the International Academy of Astronautics. In 2012, Time selected Loeb as one of the 25 most influential people in space. He lives near Boston, Massachusetts.

Can Politics and Truth Coexist?

Can Politics and Truth Coexist?

Do any of us really care about truth when it comes to politics? Should we? In a world of big lies, denialism, and conspiracy theories, democracies are experiencing two interlocked crises: a loss of confidence in democracy itself and the growing sense among many that politics is only about power—not truth. In his new book, Michael Patrick Lynch argues that truth not only can—but must—matter in politics. He shows why truth is an essential democratic value—a value we need to sustain our democratic way of life—and how it can be strengthened. Despite evidence that people are rarely motivated by truth when it comes to politics, Lynch argues that this isn’t inevitable. Contrary to the belief of many, political beliefs can be true or false. But if democracy is to continue to be a space of reason and not just an arena of power, we must build a better infrastructure of knowledge, including stronger schools and media, and renew our commitment to science and history. Michael Patrick Lynch is Provost Professor of the Humanities and Board of Trustees Distinguished Professor of Philosophy at the University of Connecticut. Lynch is the author or editor of ten books, including Know-it-All Society, The Internet of Us, Truth as One and Many, and the New York TimesSunday Book Review Editor’s pick, True to Life. He has spoken at TED and SXSW. In 2019 he was awarded The George Orwell Award, which recognizes writers who have made outstanding contributions to the critical analysis of public discourse. His new book is On Truth in Politics: Why Democracy Demands It.

The Science Behind Menopause

The Science Behind Menopause

When award-winning science writer Amy Alkon was blindsided by her first hot flash, it kicked off a cascade of symptoms—drenching night sweats, insomnia, and a rage she couldn’t explain. But what shocked her more was how little real science her doctor had to offer. In this episode, Alkon shares what she uncovered in her deep dive into the research on menopause and perimenopause—the critical yet often neglected years leading up to menopause when millions of women are misdiagnosed, dismissed, or simply told to “wait it out.” Drawing from her new book Going Menopostal, she explains why so much medical advice is still based on outdated or inadequate evidence, and what women can do about it. Alkon breaks down complex science with clarity, humor, and a healthy dose of skepticism, giving listeners the tools they need to ask better questions, advocate for themselves, and get the care they deserve. Whether you’re in the thick of it or simply want to be prepared, or want to support your loved ones going through menopause, this episode will leave you informed, empowered, and maybe even laughing. Amy Alkon is an independent investigative science writer specializing in “applied science”—using scientific evidence to solve real-world problems. Alkon critically evaluates and synthesizes research across disciplines and then translates it into everyday language, empowering regular people to make scientifically informed decisions for the best of their health and well-being.

Andrew Doyle: Trapped Between Woke Dogma and Right-Wing Populism

Andrew Doyle: Trapped Between Woke Dogma and Right-Wing Populism

What began as a call for justice has, in many cases, become an engine of conformity. In this searching conversation, Andrew Doyle (author, satirist, and cultural critic) joins Michael Shermer to unpack the trajectory of the woke movement: from its roots in anti-bigotry and awareness to its current entanglement with censorship, identitarian dogma, and ideological rigidity. Drawing on his new book, The End of Woke Doyle traces the intellectual history of contemporary activism, explores the authoritarian impulses emerging on both the left and the right, and makes the case for a return to classical liberalism as a defense against escalating cultural tribalism. Together, Shermer and Doyle explore themes ranging from the legacy of Shakespeare and Milton, the tension between equality and meritocracy, and the broader sociopolitical dynamics shaping public discourse. This episode offers a sharp, historically grounded analysis of one of the defining cultural shifts of our time—and a call to revive liberal principles in the face of rising ideological orthodoxy. Andrew Doyle is a writer, satirist and political commentator. He was formerly a Visiting Research Fellow at Queen’s University Belfast, and a lecturer at Oxford University where he completed his doctorate in Renaissance Literature. He is the creator of satirical character Titania McGrath, under whose name he has written two books: Woke: A Guide to Social Justice and My First Little Book of Intersectional Activism, both published by Little, Brown. Titania McGrath has over half a million followers on X. His previous books include Free Speech and Why it Matters and The New Puritans: How the Religion of Social Justice Captured the Western World. His new book is The End of Woke: How the Culture War Went Too Far and What to Expect from the Counter-Revolution.

The Myths of American Capitalism Explained

The Myths of American Capitalism Explained

Since the dawn of the Industrial Revolution, capitalism has unleashed unimaginable growth in opportunity and prosperity. And yet, at key points in American history, economic disruption has led to a greater role for government, ostensibly to protect against capitalism’s excesses. Today, government regulates, mandates, subsidizes and controls a growing share of the American economy. Today on the show, retired U.S. Senator Phil Gramm, one of America’s premier public policy advocates, and noted economist Donald J. Boudreaux look at the seven events and issues in American history that define, for most Americans, the role of government and how the 21st century world works. To many, these 5 periods of American history—the Industrial Revolution, Progressive Era, Great Depression, decline of America’s postwar preeminence in world trade, and the Great Recession—along with the existing levels of income inequality and poverty, represent strong evidence for expanding government in American life. Gramm and Boudreaux argue that the evidence might point to a contrary verdict. Phil Gramm served six years in the U.S. House of Representatives and eighteen years in the U.S. Senate where he was Chairman of the Banking Committee. Gramm is a Visiting Scholar at the American Enterprise Institute. He was Vice Chairman of UBS Investment Bank and is now Vice Chairman of Lone Star Funds. He taught Economics at Texas A&M University and has published numerous articles and books. Donald J. Boudreaux is an American economist, author, professor, and co-director of the Program on the American Economy and Globalization at the Mercatus Center at George Mason University in Fairfax, Virginia. His writings have appeared in The New York Times, Wall Street Journal, Investor’s Business Daily, The Washington Times, and many scholarly publications. Their new book is The Triumph of Economic Freedom: Debunking the Seven Great Myths of American Capitalism.

The Big Bang Wasn’t the Beginning? Exploring Cosmic Origins

The Big Bang Wasn’t the Beginning? Exploring Cosmic Origins

By most popular accounts, the universe started with a bang some 13.8 billion years ago. But what happened before the Big Bang? And how do we know it happened at all? Cosmologist Niayesh Afshordi and science communicator Phil Halper offer a tour of the peculiar possibilities: bouncing and cyclic universes, time loops, creations from nothing, multiverses, black hole births, string theories, and holograms. Incorporating insights from Afshordi’s cutting-edge research and Halper’s original interviews with scientists like Stephen Hawking, Roger Penrose, and Alan Guth, Afshordi and Halper compare these models for the origin of our origins, showing each theory’s strengths and weaknesses and explaining new attempts to test these notions. But most of all, Afshordi and Halper show that this search is filled with wonder, discovery, and community—all essential for remembering a forgotten cosmic past. Niayesh Afshordi is professor in the Department of Physics and Astronomy at the University of Waterloo and associate faculty at the Perimeter Institute for Theoretical Physics in Ontario, Canada. His prize-winning research focuses on competing models for the early universe, dark energy, dark matter, black holes, holography, and gravitational waves. Phil Halper is a fellow of the Royal Astronomical Society and a science popularizer. He is the creator of the popular YouTube series Before the Big Bang, which has had several million views. His astronomy images have been featured in major media outlets including The Washington Post, the BBC, and The Guardian, and he has published several papers in peer-reviewed journals.

Believing Is Seeing: Inside the Modern Paranormal Movement

Believing Is Seeing: Inside the Modern Paranormal Movement

In 2010, in a small New Hampshire town, next door to a copy center and framing shop, a ghost lab opened. The Kitt Research Initiative’s mission was to use the scientific method to document the existence of spirits. Founder Andy Kitt was known as a straight-shooter; he was unafraid—perhaps eager—to offend other paranormal investigators by exposing the fraudulence of their less advanced techniques. But when KRI started to lose money, Kitt began to seek funding from the paranormal community, attracting flocks of psychics, alien abductees, witches, mediums, ghost hunters, UFOlogists, cryptozoologists and warlocks from all over New England, and the world. And there were plenty of them around. Matthew Hongoltz-Hetling, author of the new book The Ghost Lab, explains the wild ecosystem of paranormal profiteers and consumers through the astonishing story of what happened in this one small town. He also maps the trends of declining scientific literacy, trust in institutions, and the diffusion of a culture that has created space for armies of pseudoscientists to step into the minds of an increasingly credulous public. Matthew Hongoltz-Hetling is a freelance journalist specializing in narrative features and investigative reporting. He was a finalist for the Pulitzer Prize. He is the author of A Libertarian Walks Into a Bearand It Sounds Like a Quack. His new book is The Ghost Lab: How Bigfoot Hunters, Mediums, and Alien Enthusiasts are Wrecking Science.
