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.

31. Amy Alkon — Unf*ckology: A Field Guide to Living with Guts and Confidence

31. Amy Alkon — Unf*ckology: A Field Guide to Living with Guts and Confidence

In this unique conversation Michael Shermer talks with the science writer and weekly advice columnist Amy Alkon about her new book, Unf*ckology: A Field Guide to Living with Guts and Confidence. She calls her book a “science-help” book, instead of “self-help” because she grounds her recommendations in solid science. Her hilarious anecdotes are there just to illustrate a scientific point. She also debunks widely-accepted but scientifically unsupported notions about self-esteem, shame, willpower, and more and demonstrates that: Thinking your way into changing (as so many therapists and self-help books advise) is the most inefficient way to go about it. The mind is bigger than the brain, meaning that your body and your behavior are your gym for turning yourself into the new, confident you. Fear is not just the problem; it’s also the solution. By targeting your fears with behavior, you make changes in your brain that reshape your habitual ways of behaving and the emotions that go with them. Shermer and Alkon also get into the #metoo movement, evolutionary psychology, politics, depression, suicide, Jordan Peterson, and other fascinating topics.

30. Dr. Ralph Lewis — Finding Meaning in a Meaningless Universe

In this wide-ranging conversation Michael Shermer talks with the author of the new book Finding Purpose in a Godless World: Why We Care Even if the Universe Doesn’t, Dr. Ralph Lewis. Dr. Lewis is a psychiatrist at the University of Toronto who works with cancer patients and others facing death. They often face existential crises, so Dr. Lewis—himself an atheist—has developed techniques to help people cope that do not depend on any one religion. His new book is about how human purpose and caring, like consciousness and absolutely everything else in existence, could plausibly have emerged and evolved unguided, bottom-up, in a spontaneous universe. He and Shermer discuss how a random world is too often misconstrued as nihilistic, demotivating, or devoid of morality and meaning. Drawing on years of wide-ranging, intensive clinical experience as a psychiatrist, and his own family experience with cancer, Dr. Lewis helps listeners understand how people cope with random adversity without relying on supernatural belief. In fact, as he explains, although coming to terms with randomness is often frightening, it can be liberating and empowering too. This remote Science Salon was recorded on July 2, 2018.

29. Colin McGinn — Mysterianism, Consciousness, Free Will, and God

This podcast was initiated after McGinn commented publicly, and critically, on Shermer’s latest Scientific American column on the mysteries of consciousness, free will, and God. The philosopher Justin Weinberg at the University of South Carolina, who runs the DailyNous website (@DailyNousEditor on Twitter) posted a dozen tweets admonishing Shermer and Scientific American for publishing such a mischaracterization of several philosophical subjects, even referencing the film Annie Hall, where Woody Allen’s character is irritated in a movie line by some bloviator yammering on about Marshall McLuhan, reaches behind a big movie poster and pulls McLuhan out of line, who then upbraiding the blowhard “I heard what you were saying! You know nothing of my work! You mean my whole fallacy is wrong. How you got to teach a course in anything is totally amazing!” To which Woody says, “Boy, if life were only like this.” Well, life can be like this, but in this case Shermer invited McGinn on the show to discuss the topics in detail in order for everyone to glean a deeper understanding. A fruitful conversation ensued on these and other important topics.

28. Edward J. Larson — On Faith and Science

28. Edward J. Larson — On Faith and Science

Throughout history, scientific discovery has clashed with religious dogma, creating conflict, controversy, and sometimes violent dispute. In this enlightening and accessible volume, distinguished historian and Pulitzer Prize-winning author Edward Larson and Michael Ruse, philosopher of science and Gifford Lecturer, offer their distinctive viewpoints on the sometimes contentious relationship between science and religion. The authors explore how scientists, philosophers, and theologians through time and today approach vitally important topics, including cosmology, geology, evolution, genetics, neurobiology, gender, and the environment. Broaching their subjects from both historical and philosophical perspectives, Larson and Ruse avoid rancor and polemic as they address many of the core issues currently under debate by the adherents of science and the advocates of faith, shedding light on the richly diverse field of ideas at the crossroads where science meets spiritual belief. In addition to these topics, Dr. Shermer and Dr. Larson discuss: the Scopes Monkey trial and how legal complications shaped its outcome, along with that of other creationism-evolution trials; what Darwin believed about God and religion; why biblical literalism took off in America in the 1960s and 1970s leading to creationist movements to rewrite science textbooks; what really happened in the Galileo trial; how so many prominent scientists throughout history believed in God but did not actually use their science to prove God’s providence; why atheism became so prominent in the early 21st century but not before, even though atheist arguments against God’s existence have been around for centuries; Gould and Dawkins and different approaches to science and religion; the rise of the nones and the decline of religion in the West (but it’s increase in other areas); the limits of human knowledge.

27. Charles S. Cockell — The Equations of Life: How Physics Shapes Evolution

27. Charles S. Cockell — The Equations of Life: How Physics Shapes Evolution

We are all familiar with the popular idea of strange alien life wildly different from life on earth inhabiting other planets. Maybe it’s made of silicon! Maybe it has wheels! Or maybe it doesn’t. In The Equations of Life, astrobiologist Charles S. Cockell makes the forceful argument that the laws of physics narrowly constrain how life can evolve, making evolution’s outcomes predictable. If we were to find on a distant planet something very much like a lady bug eating something like an aphid, we shouldn’t be surprised. The forms of life are guided by a limited set of rules, and as a result, there is a narrow set of solutions to the challenges of existence. In addition to these topics, Dr. Shermer and Dr. Cockell discuss: the origins of life on earth; the possibility of finding life on Mars and, if we did, would it have something like DNA, albeit with different base pairs?; Fermi’s paradox: if the laws of physics and evolution are so common throughout the universe, and there are so many earth-like planets in our galaxy alone (estimated to be in the billions), where is everyone?; humanity becoming an interplanetary species (possibly the first), and if so what type of governing system we should employ for, say, the first colonies on Mars.

26. Dr. Stephen T. Asma — Why We Need Religion

26. Dr. Stephen T. Asma — Why We Need Religion

In this dialogue Dr. Michael Shermer talks with philosopher Stephen T. Asma, a Professor of Philosophy and Founding Fellow of the Research Group in Mind, Science, and Culture at Columbia College, Chicago. His new book is Why We Need Religion, in which he argues that, like art, religion has direct access to our emotional lives in ways that science does not. Yes, science can give us emotional feelings of wonder and the sublime—we can feel the sacred depths of nature—but there are many forms of human suffering and vulnerability that are beyond the reach of help from science. Different emotional stresses require different kinds of rescue. Unlike secular authors who praise religion’s ethical and civilizing function, Asma argues that its core value lies in its emotionally therapeutic power. Asma and Shermer also discuss the relationship of science and religion, why people believe in God, atheism vs. agnosticism, the “new atheists”, humanism and the need for social and spiritual community, and other hot topics.

25. Richard Rhodes — Energy: A Human History

25. Richard Rhodes — Energy: A Human History

This is one of the best dialogues Dr. Shermer has ever had in his quarter century of talking to the leading scientists and scholars of our time. Listen in as he and Pulitzer Prize- and National Book Award-winning author Richard Rhodes discuss nuclear weapons, North Korea, Iran, and Russia, the psychology of Mutual Assured Destruction (MAD), human violence and its causes, the “Bullet Holocaust” (the millions of Jews and others shot to death in Eastern Europe before the death camps ramped up their killing by gas), how people become serial killers (the socialization of violence), and his new book Energy: A Human History, which reveals the fascinating history behind energy transitions over time—wood to coal to oil to electricity and beyond. People have lived and died, businesses have prospered and failed, and nations have risen to world power and declined, all over energy challenges. Ultimately, the history of these challenges tells the story of humanity itself. In Energy, Rhodes highlights the successes and failures that led to each breakthrough in energy production; from animal and waterpower to the steam engine, from internal-combustion to the electric motor. He addresses how we learned from such challenges, mastered their transitions, and capitalized on their opportunities. Rhodes also looks at the current energy landscape, with a focus on how wind energy is competing for dominance with cast supplies of coal and natural gas. He also addresses the specter of global warming, and a population hurtling towards ten billion by 2100.
