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.

102. Christopher Ryan — Civilized to Death: The Price of Progress

102. Christopher Ryan — Civilized to Death: The Price of Progress

Most of us have instinctive evidence the world is ending — balmy December days, face-to-face conversation replaced with heads-to-screens zomboidism, a world at constant war, a political system in disarray. We hear some myths and lies so frequently that they feel like truths: Civilization is humankind’s greatest accomplishment. Progress is undeniable. Count your blessings. You’re lucky to be alive here and now. Well, maybe we are and maybe we aren’t. Civilized to Deathcounters the idea that progress is inherently good, arguing that the “progress” defining our age is analogous to an advancing disease. Prehistoric life, of course, was not without serious dangers and disadvantages. Many babies died in infancy. A broken bone, infected wound, snakebite, or difficult pregnancy could be life-threatening. But ultimately, Ryan argues, were these pre-civilized dangers more murderous than modern scourges, such as car accidents, cancers, cardiovascular disease, and a technologically prolonged dying process? In Civilized to Death, Ryan makes the claim that we should start looking backwards to find our way into a better future. Ryan and Shermer also discuss: human nature: peaceful or violent? humans: spectrum or binary? what hunter-gatherers were really like and why it is so hard to know hunter-gatherers and…children, women, the elderly, sex, religion, politics and economics how egalitarian were hunter-gatherers? why hunter-gatherers don’t think of work as “work” in the way we do the lottery test: if you won the lottery would you work at your job, live in your neighborhood, live your life? was civilization the biggest mistake humans ever made? the “Big Gods” theory of religion vs. the communal theory of religion, and how we can learn from our ancestors to lead more balanced and healthier lives. Christopher Ryan, Ph.D., and his work have been featured on MSNBC, Fox News, CNN, NPR, The New York Times, The Times of London, Playboy, The Washington Post, Time, Newsweek, The Atlantic, Outside, El Pais, La Vanguardia, Salon, Seed, and Big Think. A featured speaker from TED to The Festival of Dangerous Ideas at the Sydney Opera House to the Einstein Forum in Pottsdam, Germany, Ryan has consulted at various hospitals in Spain, provided expert testimony in a Canadian constitutional hearing, and appeared in well over a dozen documentary films. Ryan puts out a weekly podcast, called Tangentially Speaking, featuring conversations with interesting people, ranging from famous comics to bank robbers to drug smugglers to porn stars to authors to plasma physicists.

101. Hugo Mercier — Not Born Yesterday: The Science of Who We Trust and What We Believe

101. Hugo Mercier — Not Born Yesterday: The Science of Who We Trust and What We Believe

Not Born Yesterday explains how we decide who we can trust and what we should believe — and argues that we’re pretty good at making these decisions. Hugo Mercier demonstrates how virtually all attempts at mass persuasion — whether by religious leaders, politicians, or advertisers — fail miserably. Drawing on recent findings from political science and other fields ranging from history to anthropology, Mercier shows that the narrative of widespread gullibility, in which a credulous public is easily misled by demagogues and charlatans, is simply wrong. Why is mass persuasion so difficult? Mercier uses the latest findings from experimental psychology to show how each of us is endowed with sophisticated cognitive mechanisms of open vigilance. Computing a variety of cues, these mechanisms enable us to be on guard against harmful beliefs, while being open enough to change our minds when presented with the right evidence. Even failures — when we accept false confessions, spread wild rumors, or fall for quack medicine — are better explained as bugs in otherwise well-functioning cognitive mechanisms than as symptoms of general gullibility. In this lively and provocative conversation Shermer and Mercier discuss: If we’re not as gullible as we’ve been led to believe, then why do so many people apparently believe in ESP, astrology, the paranormal, the supernatural, conspiracy theories, and the like? Epistemic Vigilance and skepticism why most Germans did not believe in Nazi ideology honest signaling, costly signaling, and virtue signaling Malcolm Gladwell’s book Talking to Strangers and why the “default to truth” theory is wrong. folk biology and why creationism is intuitive and evolutionary theory counterintuitive conspiracy theories and why we believe them (or not) the real meaning of conformity experiments in which people appear to go along with the group why people join cults … or ISIS. why people belong to religions, and why we are not living in a post-truth era, and why access to accurate information has never been so good. Hugo Mercier is a cognitive scientist at the Jean Nicod Institute in Paris and the coauthor of The Enigma of Reason. He lives in Nantes, France.

100. Episode Special: Ask Me Almost Anything

In this 100th episode of the Science Salon podcast Dr. Shermer gives a brief overview and history of the salon and how it evolved from the Distinguished Science Lecture Series at Caltech, which began in 1992, along with the founding of the Skeptics Society, a 501(c)(3) nonprofit science education organization, and it’s publication Skepticmagazine. Following this brief history Dr. Shermer answers questions sent to him on social media, on such topics as: ETIs and the chances we’ve been visited by aliens Generic Subjective Continuity, a secular version of reincarnation, and what happens after we die Trump-style propaganda and how to deal with it Should we separate artist from artwork, e.g., Michael Jackson’s music or Adolf Hitler’s paintings? Eliminative Materialism (a type of determinism) and its implication for moral progress How reliable are eyewitnesses, particularly those in the Bible, particularly with regard to stories about miracles? When did you first learn that we are made of stardust and how did this change your thinking? How much power do Christian Nationalists have in the U.S. today? Have you changed your mind about science, religion, health, and politics in the past ten years? Will we ever reach an end of scientific knowledge and understanding?

99. Bobby Duffy — Why We’re Wrong About Nearly Everything: A Theory of Human Misunderstanding

99. Bobby Duffy — Why We’re Wrong About Nearly Everything: A Theory of Human Misunderstanding

What percentage of the population are immigrants? How bad is unemployment? How much sex do people have? These questions are important and interesting, but most of us get the answers wrong. Research shows that people often wildly misunderstand the state of the world, regardless of age, sex, or education. And though the internet brings us unprecedented access to information, there’s little evidence we’re any better informed because of it. We may blame cognitive bias or fake news, but neither tells the complete story. In Why We’re Wrong About Nearly Everything, Bobby Duffy draws on his research into public perception across more than forty countries, offering a sweeping account of the stubborn problem of human delusion: how society breeds it, why it will never go away, and what our misperceptions say about what we really believe. We won’t always know the facts, but they still matter. Why We’re Wrong About Nearly Everything is mandatory reading for anyone interested making humankind a little bit smarter. Duffy and Shermer also discuss: cognitive biases and how they distort what we think about the world do men really have more sexual partners than women (and if so, who are they having sex with?) why we lie to ourselves and others about almost everything fears about immigrants and immigration Brexit: leave or remain and why people vote each way why we are more polarized politically than ever before (and what we can do about it) the “backfire effect”: the bad news and the good why we are not living in a post-truth era why facts matter and why free speech matters, and kids these days… Bobby Duffy is director of the Policy Institute at King’s College London. Formerly, he was managing director of the Ipsos MORI Social Research Institute and global director of the Ipsos Social Research Institute. He lives in London.

98.  Robert Pennock — An Instinct for Truth: Curiosity and the Moral Character of Science

98. Robert Pennock — An Instinct for Truth: Curiosity and the Moral Character of Science

An exploration of the scientific mindset — such character virtues as curiosity, veracity, attentiveness, and humility to evidence — and its importance for science, democracy, and human flourishing. Exemplary scientists have a characteristic way of viewing the world and their work: their mindset and methods all aim at discovering truths about nature. In An Instinct for Truth, Robert Pennock explores this scientific mindset and argues that what Charles Darwin called “an instinct for truth, knowledge, and discovery” has a tacit moral structure — that it is important not only for scientific excellence and integrity but also for democracy and human flourishing. In an era of “post-truth,” the scientific drive to discover empirical truths has a special value. Taking a virtue-theoretic perspective, Pennock explores curiosity, veracity, skepticism, humility to evidence, and other scientific virtues and vices. Shermer and Pennock discuss: the nature of science why Intelligent Design creationists are not doing bad science — they’re not doing science at all what to do with anomalies not explained by the current paradigm the role of outsiders in science what scientific training does to develop the virtues of science how authority is different from expertise when experts pronounce on ideas outside their field fraud in science and why it happens why scientists are skeptical of UFOs, ESP, bigfoot, and the like falsification of a scientific hypothesis vs. positive evidence in support of a scientific hypothesis the naturalistic fallacy and the Is-Ought problem, and the ethics of autonomous vehicles and the trolley problem. Robert T. Pennock is University Distinguished Professor of History, Philosophy, and Sociology of Science at Michigan State University in the Lyman Briggs College and the Departments of Philosophy and Computer Science and Engineering.

97. Amber Scorah — Leaving the Witness: Exiting a Religion and Finding a Life

97. Amber Scorah — Leaving the Witness: Exiting a Religion and Finding a Life

In this revealing conversation Amber Scorah opens the box into the psychology of religious belief to show how, exactly, religions and cults convince members that theirs is the one true religion, to the point, she admits, that she would have gladly died for her faith. As a third-generation Jehovah’s Witness, Amber Scorah had devoted her life to sounding God’s warning of impending Armageddon. She volunteered to take the message to China, where the preaching she did was illegal and could result in her expulsion or worse. Here, she had some distance from her community for the first time. Immersion in a foreign language and culture — and a whole new way of thinking — turned her world upside down, and eventually led her to lose all that she had been sure was true. As a proselytizer in Shanghai, using fake names and secret codes to evade the authorities’ notice, Scorah discreetly looked for targets in public parks and stores. To support herself, she found work at a Chinese language learning podcast, hiding her real purpose from her coworkers. Now with a creative outlet, getting to know worldly people for the first time, she began to understand that there were other ways of seeing the world and living a fulfilling life. When one of these relationships became an “escape hatch,” Scorah’s loss of faith culminated in her own personal apocalypse, the only kind of ending possible for a Jehovah’s Witness. Shunned by family and friends as an apostate, Scorah was alone in Shanghai and thrown into a world she had only known from the periphery — with no education or support system. A coming of age story of a woman already in her thirties, this unforgettable memoir examines what it’s like to start one’s life over again with an entirely new identity. Scorah and Shermer also discuss: the legals and logistics of writing a memoir the rise of the nones and disbelief and why stories like hers provide social proof for living without religion what Jehovah’s Witnesses believe and why they believe it what it’s like to go door-to-door witnessing for a religion Armageddon and what doomsayers do when the world doesn’t end the mindset of the fundamentalist why religions are obsessed with female sexuality why religions forbid homosexuality the psychology of deconversion the problem of evil, or why bad things happen to good people how she would try to talk someone out of joining ISIS what it’s like to be expelled from a religion and be an apostate, and how to start your life over when you’ve lost everything. Amber Scorah is a writer living in Brooklyn, NY. Her articles have been published in The New York Times, The Believer, and USA Today. Prior to coming to New York, Scorah lived in Shanghai, where she was creator and host of the podcast Dear Amber: An Insider’s Guide to Everything China. Leaving the Witness is her first book.

96. Catherine Wilson — How to Be an Epicurean: The Ancient Art of Living Well

96. Catherine Wilson — How to Be an Epicurean: The Ancient Art of Living Well

In this wide-ranging conversation the philosopher Catherine Wilson makes the case that if the pursuit of happiness is the question, Epicureanism is the answer. Not the mythic Epicureanism that calls to mind gluttons with gout or an admonition to eat, drink, and be merry. Instead, in her new book How to Be an Epicurean, Wilson shows that Epicureanism isn’t an excuse for having a good time: it’s a means to live a good life. Although modern conveniences and scientific progress have significantly improved our quality of life, many of the problems faced by ancient Greeks — love, money, family, politics — remain with us in new forms. To overcome these obstacles, the Epicureans adopted a philosophy that promoted reason, respect for the natural world, and reverence for our fellow humans. By applying this ancient wisdom to a range of modern problems, from self-care routines and romantic entanglements to issues of public policy and social justice, Wilson shows us how we can all fill our lives with purpose and pleasure. Wilson and Shermer also discuss: the hedonic treadmill and the problem of pursuing material goods why money will not bring you happiness or meaning eternal moral truths judging figures from the past by modern moral standards why she thinks everyone from Thomas Jefferson to Joe Biden should have known better and acted differently why she thinks Jeffrey Epstein committing suicide was a rational choice for him how to think about the abortion issue why we need not fear death, and how to lead a meaningful life. Catherine Wilson received her PhD in philosophy from Princeton University and has taught at universities in the US, Canada, and Europe. She has published more than 100 research papers and eight books, including A Very Short Introduction to Epicureanism and Metaethics from a First-Person Standpoint: An Introduction to Moral Philosophy. She has two children and lives in New York City, where she is currently Visiting Presidential Professor of Philosophy at the Graduate Center at CUNY.

95. John Martin Fischer — Death, Immortality and Meaning in Life

John Martin Fischer’s Death, Immortality, and Meaning in Lifeoffers a brief yet in-depth introduction to the key philosophical issues and problems concerning death and immortality. In this wide-ranging and thoughtful conversation, Shermer and Fisher discuss: meaning in life meaning in death the badness of death different philosophical, religious, and scientific ideas on immortality near-death experiences extending life through medical technology medical immortality vs. real immortality the problem of identity for immortality (who or what becomes immortal?) living for 100 years vs. 1000 years vs. forever responding to the theistic argument that without God anything goes, there is no objective morality, and no meaning to life If you don’t believe in God or the afterlife, what do you say to someone who is dying or has lost a loved one? Is immortality, like existence, one thought too many? John Martin Fischer is Distinguished Professor of Philosophy at the University of California, Riverside, and a University Professor at the University of California. He is coauthor of Near-Death Experiences: Understanding Visions of the Afterlife (OUP, 2016), and coeditor of Introduction to Philosophy: Classical and Contemporary Readings(Eighth Edition, OUP, 2018).
