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.

94. David Leiser — How We Misunderstand Economics and Why it Matters

94. David Leiser — How We Misunderstand Economics and Why it Matters

This is the first book to explain why people misunderstand economics. From the cognitive shortcuts we use to make sense of complex information, to the metaphors we rely on and their effect on our thinking, this important book lays bare not only the psychological traits that distort our ability to understand such a vital topic, but also what this means for policy makers and civil society more widely. Shermer and Leiser dive into the mismatch between the complexities of economics and the constraints of human cognition that lie at the root of our misconceptions, as well as explore: folk economics and why our intuitions are so often wrong the evolutionary origins of our thinking about economics and why we are not prepared cognitively to understand complex economic ideas Universal Basic Income income inequality CEO pay and why we think it’s too high the importance of trust in economic exchanges tariffs and Trump China, and reparations for slavery vs. reparations for the Holocaust. David Leiser is Full Professor of Economic and Social Psychology at Ben-Gurion University of the Negev, Israel. He is Past President of the International Association for Research in Economic Psychology, and President of the Economic Psychology Division of the International Association of Applied Psychology. He studies lay conceptions, especially in the economic domain. Listen to Science Salon via Apple Podcasts, Spotify, Google Play Music, Stitcher, iHeartRadio, and TuneIn.

92. Tim Samuels — Future Man: How to Evolve and Thrive in the Age of Trump, Mansplaining, and #MeToo

92. Tim Samuels — Future Man: How to Evolve and Thrive in the Age of Trump, Mansplaining, and #MeToo

If ever there was an urgent need for a frank understanding of what’s going on with men, it is now. Male rage and frustration have driven resurgent populism, mass shootings, and epidemics of addiction and violence. Powerful men who have abused their positions for decades have been and are being #MeToo-outed and dismissed. The patriarchy, that solid bedrock of male power for thousands of years, seems to be crumbling. In Future Man, with his characteristic intelligence and humor, Tim Samuels assesses the state of contemporary manhood, its conflicts, confusions, and challenges. Trapped in bodies barely changed since cavemen days, men are contending with the stresses of corporate culture, lifelong commitment, rampant depression, and crazy expectations to be successful at work and at home. But how can you hunt and gather in an open-plan office? Why do men make up to 95 percent of Fortune 500 CEOs yet 93 percent of the prison population? Why do men commit suicide at more than three times the rate of women? Shermer and Samuels discuss: why it’s time for men to listen to women why it is also time for women to listen to (non-toxic) men why the treatment of women and men is not zero-sum fatherhood violence and how to curb it war and what it does to men porn and the problems it causes why men need sports mental health toxic masculinity gender roles divorce, child custody, alimony, and spousal support. Tim Samuels is an award-winning documentary filmmaker, broadcaster, and journalist. He won three Royal Television Society awards and best documentary at the World Television Festival as well as the “Making a Difference” award at the Mind Media Awards for his work on mental health. He created the BBC Radio 5 call-in show Men’s Hour and has been a host for eight years. He recently became a correspondent for National Geographic Channel’s Explorer, based out of New York, and he contributes to such US publications as GQ, New York Times Magazine, and Huffington Post.

90. Melvin Konner — Believers: Faith in Human Nature

90. Melvin Konner — Believers: Faith in Human Nature

World renowned biological anthropologist Mel Konner examines the nature of human nature, including and especially in his new book the nature of religiosity. In Believers, Konner, who was raised in an orthodox Jewish home but has been an atheist his entire adult life, responds to attacks on faith by some well-meaning scientists and philosophers, most notably the “new atheists” Richard Dawkins, Daniel Dennett, Sam Harris, and Christopher Hitchens―known for writing about religion as something irrational and ultimately harmful. Konner explores the psychology, development, brain science, evolution, and even genetics of the varied religious impulses we experience as a species. Konner and Shermer discuss:   the nature of human nature what is religion? what is faith? is religion and faith adaptive or the byproduct of some other evolved adaptation? his experience living among hunter-gatherers how hunter-gatherers conceive of religion vs. modern peoples the “Big Gods” theory of religion the “God Module” theory of religion the group selection theory of religion why faith is not for everyone the rise of the nones, but why religion will never completely die out the upside of religion … and the downside were our paleolithic ancestors warlike or peaceful? would you want to switch places and live in a hunter-gatherer society? why for at least a large minority of humanity, the belief in things unseen neither can nor should go away. Melvin Konner, MD, is Samuel Candler Dobbs Professor in the Department of Anthropology and the Program in Neuroscience and Behavioral Biology at Emory University. He is the author of Believers, Women After All, Becoming a Doctor, and The Tangled Wing, among other books.

89. Richard Dawkins — Outgrowing God: A Beginner’s Guide

89. Richard Dawkins — Outgrowing God: A Beginner’s Guide

In 12 fiercely funny, mind-expanding chapters, Richard Dawkins explains how the natural world arose without a designer — the improbability and beauty of the “bottom-up programming” that engineers an embryo or a flock of starlings — and challenges head-on some of the most basic assumptions made by the world’s religions.   In this wide-ranging conversation Shermer and Dawkins discuss: how Outgrowing God encapsulates his life’s work in two broad areas: (1) science, reason, and evolution theory; (2) God, Religion, and Faith. A “Dawkins 101” book and a perfect gift to friends and family. his commitment to the truth, as best explained by science. Is the Bible a “Good Book”? Is adhering to a religion necessary, or even likely, to make people good to one another? why religion is over-determined separating religion from God beliefs Is religion and belief in God an evolutionary adaptation or a byproduct (or both)? Why we don’t need God in order to be good How do we decide what is good? human nature: selfish/selfless, violent/peaceful, better angels/inner demons breaching the Is-Ought barrier the future of atheism career advice for young scientists and scholars getting courage from science the multiverse: “You Cannot be Serious!” Richard Dawkins is a fellow of the Royal Society and was the inaugural holder of the Simonyi Chair for the Public Understanding of Science at Oxford University. He is the acclaimed author of many books, including The Selfish Gene, The God Delusion, The Magic of Reality, Climbing Mount Improbable, Unweaving the Rainbow, The Ancestor’s Tale, The Greatest Show on Earth, and Science in the Soul. He is the recipient of numerous honors and awards, including the Royal Society of Literature Award, the Michael Faraday Prize of the Royal Society, the Kistler Prize, the Shakespeare Prize, the Lewis Thomas Prize for Writing about Science, the Galaxy British Book Awards Author of the Year Award, and the International Cosmos Prize of Japan.

88. Daniel Oberhaus — Extraterrestrial Languages

88. Daniel Oberhaus — Extraterrestrial Languages

The endlessly fascinating question of whether we are alone in the universe has always been accompanied by another, more complicated one: if there is extraterrestrial life, how would we communicate with it? In his book Extraterrestrial Languages, Daniel Oberhaus leads readers on a quest for extraterrestrial communication. Exploring Earthlings’ various attempts to reach out to non-Earthlings over the centuries, he poses some not entirely answerable questions. If we send a message into space, will extraterrestrial beings receive it? Will they understand? What languages will they (and we) speak? If we can’t even communicate with dolphins and whales, which are mammals, or chimpanzees and gorillas, which are primates, how are we going to communicate with sentient beings that evolved on another planet? If we want to send a message to far-future humans to, say, warn them not to open a container of radioactive waste from a nuclear plant, what would we put on the container to communicate the danger within? Is there not only a universal grammar (as Noam Chomsky has posited), but also a grammar of the universe? In this incredibly fascinating conversation Shermer and Oberhaus also discuss: the late-19th-century idea to communicate with Martians via Morse code and mirrors the emergence in the 20th century of SETI (the search for extraterrestrial intelligence), CETI (communication with extraterrestrial intelligence), and finally METI (messaging extraterrestrial intelligence) the one-way space voyage of Ella, an artificial intelligence agent that can play cards, tell fortunes, and recite poetry different media used in attempts at extraterrestrial communication, from microwave systems to plaques on spacecrafts to formal logic, and our attempts to formulate a language for our message, including the Astraglossa and two generations of Lincos (lingua cosmica) how philosophy, linguistics, mathematics, science, and art have informed the design or limited the effectiveness of our interstellar messaging. Daniel Oberhaus is a science and technology journalist whose work has appeared in Wired, the Atlantic, Popular Mechanics, Slate, the Baffler, Nautilus, Vice, the Awl, and other publications.

87. Douglas Murray — The Madness of Crowds: Gender, Race, and Identity

87. Douglas Murray — The Madness of Crowds: Gender, Race, and Identity

In his devastating new book The Madness of Crowds, Douglas Murray examines the 21st century’s most divisive issues: sexuality, gender, technology and race. He reveals the astonishing new culture wars playing out in our workplaces, universities, schools and homes in the names of social justice, identity politics and intersectionality. We are living through a postmodern era in which the grand narratives of religion and political ideology have collapsed. In their place have emerged a crusading desire to right perceived wrongs and a weaponization of identity, both accelerated by the new forms of social and news media. Narrow sets of interests now dominate the agenda as society becomes more and more tribal — and, as Murray shows, the casualties are mounting. Readers of all political persuasions cannot afford to ignore Murray’s masterfully argued and fiercely provocative book, in which he seeks to inject some sense into the discussion around this generation’s most complicated issues. He ends with an impassioned call for free speech, shared common values and sanity in an age of mass hysteria. Shermer and Murray discuss: gay: born this way? race: why current attitudes are an inversion of Martin Luther King Jr.’s dream gender: is it really all about power? Men and women in the workplace trans: how big an issue is this and how many trans people are there? Reversing trans surgeries the problem of intersectionality, or the oppression olympics campus craziness: how big a problem is it really? political correctness and free speech the problem of “overcorrection” in moral progress, and the way forward. Douglas Murray is an author and journalist based in Britain. His previous book, The Strange Death of Europe: Immigration, Identity, Islam, was a No. 1 bestseller in non-fiction. Murray has been a contributor to the Spectator since 2000 and has been Associate Editor at the magazine since 2012. He has also written regularly for numerous other outlets including the Wall Street Journal, the Times, the Sunday Times, the Sun, Evening Standard and the New Criterion. He is a regular contributor to National Review and has been a columnist for Standpoint magazine since its founding.
