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.

86. Neil deGrasse Tyson — Letters from an Astrophysicist

86. Neil deGrasse Tyson — Letters from an Astrophysicist

Astrophysicist Neil deGrasse Tyson has attracted one of the world’s largest online followings with his fascinating, widely accessible insights into science and our universe. Now, Tyson invites us to go behind the scenes of his public fame by revealing his correspondence with people across the globe who have sought him out in search of answers. In this hand-picked collection of 101 letters, Tyson draws upon cosmic perspectives to address a vast array of questions about science, faith, philosophy, life, and of course, Pluto. His succinct, opinionated, passionate, and often funny responses reflect his popularity and standing as a leading educator. Tyson’s 2017 bestseller Astrophysics for People in a Hurry offered more than one million readers an insightful and accessible understanding of the universe. Tyson’s most candid and heartfelt writing yet, Letters from an Astrophysicist introduces us to a newly personal dimension of Tyson’s quest to explore our place in the cosmos. Shermer and Tyson discuss: killing Pluto killing God science and religion why he takes a relatively conciliatory approach to religion why he takes a hard-line against science deniers in religion (and elsewhere) progress in science how vs. why questions race and racial progress why the arc of the moral universe still bends toward justice race and IQ and the curious letter he received about how to address this sensitive subject his middle name and why one correspondent objected to it Neil’s father and why he ends the book with a eulogy.

85. Deepak Chopra — Metahuman: Unleashing Your Infinite Potential

85. Deepak Chopra — Metahuman: Unleashing Your Infinite Potential

In this conversation long-time adversaries and now friends Michael Shermer and Deepak Chopra make an attempt at mutual understanding through the careful unpacking of what Deepak means when he talks about the subject-object split, the impermanence of the self, nondualism, the mind-body problem, the nature of consciousness, and the nature of reality. Shermer also pushes Deepak to translate these deep philosophical, metaphysical, and psychological concepts into actionable take-home ideas that can be put to use to reduce human suffering and help people lead lives that are more meaningful and purposeful. In the book Deepak includes a survey called Nondual Embodiment Thematic Inventory (NETI), final scores of which range from 20 to 100, on “how people rank themselves on qualities long considered spiritual, psychological, or moral.” Shermer scored a 62, which Chopra said is “not bad”.

84. Christof Koch — The Feeling of Life Itself: Why Consciousness is Widespread but Can’t Be Computed

84. Christof Koch — The Feeling of Life Itself: Why Consciousness is Widespread but Can’t Be Computed

In this fascinating discussion of one of the hardest problems in all of science — the hard problem of consciousness, that is, explaining how the feeling or experience of something can arise from neural activity — one of the world’s leading neuroscientists Christof Koch argues that consciousness, more widespread than previously assumed, is the feeling of being alive, not a type of computation or a clever hack. Consciousness is experience. Consciousness is, as his book title states, The Feeling of Life Itself — the feeling of being alive. Shermer and Koch discuss: the Neural Correlates of Consciousness (NCC) where consciousness is located in the brain (or, more precisely, where it is not located) what comas and vegetative states teach us about consciousness what brain injuries and diseases teach us about consciousness what hallucinogens teach us about consciousness what split-brain surgeries teach us about the nature of the self and identity Koch’s experience with psilocybin and what he learned about consciousness Koch’s experience in a flotation tank and what he learned about consciousness why computers as they are currently configured can never create consciousness why mind-uploading cannot copy or continue consciousness Integrated Information Theory of Consciousness Global Workspace Theory of Consciousness why consciousness is not an illusion, and mysterian mysteries. Christof Koch is President and Chief Scientist of the Allen Institute for Brain Science in Seattle, following twenty-seven years as a Professor at the California Institute of Technology. He is the author of Consciousness: Confessions of a Romantic Reductionist (MIT Press), The Quest for Consciousness: A Neurobiological Approach, and other books.

83. Peter Boghossian — How to Have Impossible Conversations: A Very Practical Guide

83. Peter Boghossian — How to Have Impossible Conversations: A Very Practical Guide

In our current political climate, it seems impossible to have a reasonable conversation with anyone who has a different opinion. Whether you’re online, in a classroom, an office, a town hall — or just hoping to get through a family dinner with a stubborn relative — dialogue shuts down when perspectives clash. Heated debates often lead to insults and shaming, blocking any possibility of productive discourse. Everyone seems to be on a hair trigger. In How to Have Impossible Conversations, Peter Boghossian and James Lindsay guide you through the straightforward, practical, conversational techniques necessary for every successful conversation — whether the issue is climate change, religious faith, gender identity, race, poverty, immigration, or gun control. Boghossian and Lindsay teach the subtle art of instilling doubts and opening minds. They cover everything from learning the fundamentals for good conversations to achieving expert-level techniques to deal with hardliners and extremists. Shermer and Boghossian discuss: the growing political divide in American over the past quarter century why politicians no longer reach across the aisle when is the right time to have a difficult conversation the best strategies to use to diffuse anger and keep a conversation productive why the atheist movement splintered over disagreements strategies used by hostage negotiators that you can employ in your conversations, and negotiating the intractable social media. Peter Boghossian is a full time faculty member in the philosophy department at Portland State University and an affiliated faculty member at Oregon Health Science University in the Division of General Internal Medicine. He is a national speaker for the Center of Inquiry and an international speaker for the Richard Dawkins Foundation for Reason and Science, and the author of A Manual for Creating Atheists.

82. Phil Zuckerman — What it Means to be Moral: Why Religion is Not Necessary for Living an Ethical Life

82. Phil Zuckerman — What it Means to be Moral: Why Religion is Not Necessary for Living an Ethical Life

In What It Means to Be Moral: Why Religion Is Not Necessary for Living an Ethical Life, Phil Zuckerman argues that morality does not come from God. Rather, it comes from us: our brains, our evolutionary past, our ongoing cultural development, our social experiences, and our ability to reason, reflect, and be sensitive to the suffering of others. By deconstructing religious arguments for God-based morality and guiding readers through the premises and promises of secular morality, Zuckerman argues that the major challenges facing the world today―from global warming and growing inequality to religious support for unethical political policies to gun violence and terrorism―are best approached from a nonreligious ethical framework. In short, we need to look to our fellow humans and within ourselves for moral progress and ethical action. Shermer and Zuckerman discus: what is morality and what does it mean to be good? the evolutionary origins of morality the “naturalistic fallacy,” or the “is-ought fallacy” and why it need not always apply how we’ve made moral progress over the centuries thanks to secular forces why religion is always behind the wave of moral progress (but takes credit for it later) the origin of good and evil how to solve crime, homelessness, and other social problems through science, reason, and secular forces, and the seven secular virtues. Dr. Phil Zuckerman is the author of several books, including The Nonreligious, Living the Secular Life, Society without God, and his latest book, What it Means to be Moral. He is a professor of sociology at Pitzer College and the founding chair of the nation’s first secular studies program. He lives in Claremont, California, with his wife and three children.

81. Bruce Hood — Possessed: Why We Want More Than We Need

81. Bruce Hood — Possessed: Why We Want More Than We Need

You may not believe it, but there is a link between our current political instability and your childhood attachment to teddy bears. There’s also a reason why children in Asia are more likely to share than their western counterparts and why the poor spend more of their income on luxury goods than the rich. Or why your mother is more likely to leave her money to you than your father. What connects these things? The answer is our need for ownership. Award-winning University of Bristol psychologist Bruce Hood draws on research from his own lab and others around the world to explain why this uniquely human preoccupation governs our behavior from the cradle to the grave, even when it is often irrational, and destructive. What motivates us to buy more than we need? Is it innate, or cultural? How does our urge to acquire control our behaviour, even the way we vote? And what can we do about it? Possessed is the first book to explore how ownership has us enthralled in relentless pursuit of a false happiness, with damaging consequences for society and the planet — and how we can stop buying into it. Dr. Hood and Dr. Shermer also discuss: who owns your body and mind how the military draft, conscription, is a way of the state taking possession of your body suicide and bodily ownership: why states prohibit you from killing yourself organs and bodily ownership: why states prohibit you from selling your organs prostitution: why states prohibit people from selling their bodies for sex slavery: why historically states have legalized owning other people marriage & children: why historically states have sanctioned men owning women and children children’s sense of ownership income inequality objects vs. money vs. social capital as possessions money is not a possession so much as a means of getting possessions. jealousy as a form of possession xenophobia as a fear of loss of ownership who owns the land, air, water, minerals, etc.? intellectual Property: who owns your ideas? what wills and trusts tell us about the psychology of the transfer of ownership the tragedy of the commons and environmental protection through private ownership: Ducks Unlimited, game reserves, licenses for killing big game in Africa why original art is more valuable than fakes or duplicates, and the Arab-Israel conflict and what happens when God ordains ownership of a piece of land to two different peoples.

79. Anthony Kronman — The Assault on American Excellence

79. Anthony Kronman — The Assault on American Excellence

The former dean of Yale Law School argues that the feverish egalitarianism gripping college campuses today is out of place at institutions whose job is to prepare citizens to live in a vibrant democracy. In his tenure at Yale, Anthony Kronman has watched students march across campus to protest the names of buildings and seen colleagues resign over emails about Halloween costumes. He is no stranger to recent confrontations at American universities. But where many see only the suppression of free speech, the babying of students, and the drive to bury the imperfect parts of our history, Kronman recognizes in these on-campus clashes a threat to our democracy. Shermer and Kronman discuss: free speech vs. hate speech how language effects how we think about other people diversity of characteristics (race, gender) vs. diversity of viewpoints the search for universal truths vs. understanding other’s perspectives affirmative action in the academy: from the University of California to Harvard taking down statues of Hitler and Stalin vs. taking down statues of Confederate Generals the problem of applying current moral values to the past, and how to reform the academy to refocus on excellence. Anthony T. Kronman served as the dean of Yale Law School from 1994–2004, and has taught at the university for forty years. He is the author or coauthor of five books, including The Assault on American Excellence; Education’s End: Why Our Colleges and Universities Have Given Up on the Meaning of Life; and Confessions of a Born-Again Pagan.
