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.

141. Richard Kreitner — Break it Up: Secession, Division, and the Secret History of America’s Imperfect Union

141. Richard Kreitner — Break it Up: Secession, Division, and the Secret History of America’s Imperfect Union

The provocative thesis of Break It Up is simple: The United States has never lived up to its name—and never will. The disunionist impulse may have found its greatest expression in the Civil War, but as Break It Up shows, the seduction of secession wasn’t limited to the South or the 19thcentury. It was there at our founding and has never gone away. Investigative journalist Richard Kreitner takes readers on a revolutionary journey through American history, revealing the power and persistence of disunion movements in every era and region. Each New England town after Plymouth was a secession from another; the 13 colonies viewed their Union as a means to the end of securing independence, not an end in itself; George Washington feared separatism west of the Alleghenies; Aaron Burr schemed to set up a new empire; John Quincy Adams brought a Massachusetts town’s petition for dissolving the United States to the floor of Congress; and abolitionist William Lloyd Garrison denounced the Constitution as a pro-slavery pact with the devil. From the “cold civil war” that pits partisans against one another to the modern secession movements in California and Texas, the divisions that threaten to tear America apart today have centuries-old roots in the earliest days of our Republic. Richly researched and persuasively argued, Break It Up will help readers make fresh sense of our fractured age. Shermer and Kreitner discuss: what happens if Trump loses the 2020 election and refuses to leave, the possibility of the secession of California, Oregon and Washington, States rights vs. Federal power in issues like climate change, abortion, health care, etc., how Native American tribes and nations governed themselves and what the colonists learned from them, how the 1st colonial revolution was fought not to create a federation but to destroy one when Boston rebelled against the Crown-backed Dominion of New England, separatists movements throughout our history, Aaron Burr’s attempts to create a new nation he would head, spread of slavery to the west and Jefferson’s fear that it sounded like a “fire bell in the night,” why John Quincy Adams introduced a petition demanding the dissolution of the U.S.: If the day should ever come, (may Heaven avert it,) when the affection of the people of these states shall be alienated from each other; when the fraternal spirit shall give away to cold indifference, or collisions of interest shall fester into hatred, far better will it be for the people of the disunited states, to part in friendship from each other, than to be held together by constraint. how Southern states initially sought to expand the union of slave holding states, not secession, why reconstruction failed, the Civil War of the 1960s, Brexit, Texit, and Calexit, Russia support for American secessionist movements, James Madison’s observation (in Federalist Paper No. 51) about the problem all human groups/tribes/nations must solve: But what is government itself, but the greatest of all reflections on human nature? If men were angels, no government would be necessary. If angels were to govern men, neither external nor internal controls on government would be necessary. In framing a government which is to be administered by men over men, the great difficulty lies in this: you must first enable the government to control the governed; and in the next place oblige it to control itself. Kreitner’s summation of America’s irrepressible conflict “The ‘irrepressible conflict’ was not just between North and South, freedom and slavery; it reflected something even deeper. The truly ‘irrepressible’ conflict was between union and disunion, whose forces bringing American together and those tearing them apart.” Richard Kreitner is a contributing writer to The Nation. He is the author of Booked: A Traveler’s Guide to Literary Locations Around the World. A graduate of McGill University, he has also written for The New York Times, Slate, Salon, The Baffler, Raritan, The Forward, and the Boston Globe. He lives in Brooklyn with his wife and daughter.

140. Rebecca Wragg Sykes — Kindred: Neanderthal Life, Love, Death and Art

140. Rebecca Wragg Sykes — Kindred: Neanderthal Life, Love, Death and Art

The common narrative of Neanderthals is that they were a group of dullard losers whose extinction 40,000 years ago was due to smarter competition and a little of interbreeding with our own forebears. Likening someone to a Neanderthal was and, most likely, still is a top-rate anthropological insult. But, in the past few decades, Neanderthal finds have greatly contradicted our perception of the species. In Kindred, Rebecca Wragg Sykes combs through the avalanche of scientific discoveries of the species and uses her experience at the cutting-edge of Paleolithic research to share our new understanding of Neanderthals, shoving aside cliches of rag-clad brutes in an icy wasteland. She reveals them to be curious, clever connoisseurs of their world, technologically inventive and ecologically adaptable. They ranged across vast tracts of tundra and steppe, but also stalked in dappled forests and waded in the Mediterranean Sea. Above all, they were successful survivors for more than 300,000 years, during times of massive climatic upheaval. Shermer and Sykes also discuss: the nature of species and if Neanderthals and Homo sapiens are one or two species, the deep time span of Neanderthals, the wide geography of Neanderthals, how archaeologists work today to discern Neanderthal lives and minds, Neanderthal DNA and what we have learned from it, Neanderthal bodies, Neanderthal brains and minds, Neanderthal tools and what they tell us about their lives, Neanderthal hunting/caloric needs, Neanderthal art, Neanderthal sex and love and social lives, Neanderthal death, burial, afterlife beliefs, and possible religious beliefs, and extinction: what happened to the Neanderthals? Rebecca Wragg Sykes has been fascinated by the vanished worlds of the Pleistocene ice ages since childhood, and followed this interest through a career researching the most enigmatic characters of all, the Neanderthals. After a Ph.D. on the last Neanderthals living in Britain, she worked in France at the world-famous PACEA laboratory, Université de Bordeaux, on topics ranging from Neanderthal landscapes and territories in the Massif Central region of south-east France, to examining how they were the first ancient humans to produce a synthetic material and tools made of multiple parts. Alongside her academic activities, she has also earned a reputation for exceptional public engagement. The public can follow her research through a personal blog and Twitter account, and she frequently writes for the popular media, including the Scientific American and Guardian science blogs. Becky is passionate about sharing the privileged access scientists have to fascinating discoveries about the Neanderthals. She is also co-founder of the influential Trowelblazers project, which highlights women archaeologists, palaeontologists and geologists through innovative outreach and collaboration.

139. Shelby Steele — Shame: How America’s Past Sins Have Polarized Our Country & the film What Killed Michael Brown?

139. Shelby Steele — Shame: How America’s Past Sins Have Polarized Our Country & the film What Killed Michael Brown?

The United States today is hopelessly polarized; the political Right and Left have hardened into rigid and deeply antagonistic camps, preventing any sort of progress. Amid the bickering and inertia, the promise of the 1960s—when we came together as a nation to fight for equality and universal justice—remains unfulfilled. As Shelby Steele reveals in Shame, the roots of this impasse can be traced back to that decade of protest, when in the act of uncovering and dismantling our national hypocrisies—racism, sexism, militarism—liberals internalized the idea that there was something inauthentic, if not evil, in the America character. Since then, liberalism has been wholly concerned with redeeming modern America from the sins of the past, and has derived its political legitimacy from the premise of a morally bankrupt America. The result has been a half-century of well-intentioned but ineffective social programs, such as Affirmative Action. Steele reveals that not only have these programs failed, but they have in almost every case actively harmed America’s minorities and poor. Ultimately, Steele argues, post-60s liberalism has utterly failed to achieve its stated aim: true equality. Liberals, intending to atone for our past sins, have ironically perpetuated the exploitation of this country’s least fortunate citizens. Approaching political polarization from a wholly new perspective, Steele offers a rigorous critique of the failures of liberalism and a cogent argument for the relevance and power of conservatism. Shermer and Steele discuss: 30th anniversary of his book The Content of Our Character, and what has changed in race relations in America in those 30 years? Steele’s response to President Johnson’s famous quote: “Freedom is not enough. You do not take a person who, for years, has been hobbled by chains and liberate him; bring him up to the starting line of a race and then say, ‘you are free to compete with all the others,’ and still justly believe that you have been completely fair.” why “The promised land guarantees nothing. It is only an opportunity, not a deliverance.”, literal truths vs. poetic truths and power: “What actually happened was that liberalism turned to poetic truth when America’s past sins were no longer literally true enough to support liberal policies and the liberal claim on power. The poetic truth of black victimization seeks to compensate for America’s moral evolution. It tries to keep alive the justification for liberal power even as that justification has been greatly nullified by America’s moral development.”   political correctness is the enforcement arm of poetic truth, black families & fatherless homes, white guilt, race fatigue, reparations, anti-racism, achievement gap, Princeton racism letter, race and IQ, SAT tests, BLM and the nuclear family, training and sensitivity programs. Shermer and Steele also discuss his new film, produced with his son Eli Steele, titled What Killed Michael Brown? Steele: “We human beings never use race except as a means to power. Race is never an end. It is always a means, and it has no role in human affairs except as a corruption.” “America’s original sin is not slavery. It is simply the use of race as a means to power. Whether for good or ill, race is a corruption. Always. And it always turns one group into the convenience of another group.” “Liberalism’s great sin was to steal responsibility for black problems away from black people, leaving them vulnerable to destructive social forces, such as the drug epidemic of the 70s and 80s. It was the suffering of blacks that justified liberalism’s demand for power, but this only relegates blacks to permanent victimhood and alienates them from the power to uplift themselves.” Shelby Steele is the Robert J. and Marion E. Oster Senior Fellow at the Hoover Institution. Winner of the Bradley Prize and a National Humanities Medal and the author of the National Book Critics Circle award-winning The Content of Our Character, Steele lives in the Central Coast of California.

138. Douglas Murray — The Madness of 2020

138. Douglas Murray — The Madness of 2020

In this special episode of the Science Salon Podcast, Michael Shermer catches up with Douglas Murray one year after the publication of his bestselling book The Madness of Crowds, which was featured in Science Salon # 87 in October 2019. Murray’s book is now out in paperback with an Afterword update on all that has happened the past year, one of the most momentous in living memory. Shermer and Murray discuss: why he wasn’t “cancelled” after The Madness of Crowds was published and became a bestseller, what people should do if they’re cancelled, shamed, mobbed, or accused of being racist, misogynist, transphobic, or bigoted and they know they’re not, how to fight back against wokeness, political correctness, and identity politics, updates on the featured topics in The Madness of Crowds: gay, women, race, trans, J.K. Rowling and “people who menstruate” (if only there was a single word for that phrase), statues and why some people want them taken down (Lord Nelson may be next…find out why), why leftists think everyone (except them) are racists and why they’re really making these accusations, why we should be suspect of the motives of social justice warriors (who are anti-social, against justice, and not warriors), Michael Brown, George Floyd, and police violence, white fragility, white guilt, BLM, and anti-racism, corporate sensitivity training programs and why they’re really being conducted, what could happen after the 2020 election, depending on who wins, and comparing 2020 to 1968, and what the future holds for Western culture. In The Madness of Crowds Douglas Murray investigates the dangers of “woke” culture and the rise of identity politics. In lively, razor-sharp prose he examines the most controversial issues of our moment: sexuality, gender, technology and race, with interludes on the Marxist foundations of “wokeness”, the impact of tech and how, in an increasingly online culture, we must relearn the ability to forgive. One of the few writers who dares to counter the prevailing view and question the dramatic changes in our society — from gender reassignment for children to the impact of transgender rights on women — Murray’s penetrating book clears a path of sanity through the fog of our modern predicament. Douglas Murray is a regular columnist for both the Spectator and Standpoint and writes frequently for a variety of other publications, including the Sunday Times and Wall Street Journal. A prolific debater, Douglas has spoken on a variety of prominent platforms, including at the British and European Parliaments and the White House.

137. Marta Zaraska — Growing Young: How Friendship, Optimism, and Kindness Can Help You Live to 100

137. Marta Zaraska — Growing Young: How Friendship, Optimism, and Kindness Can Help You Live to 100

From the day her daughter was born, science journalist Marta Zaraska fretted about what she and her family were eating. She fasted, considered adopting the keto diet, and ran a half-marathon. She bought goji berries and chia seeds and ate organic food. But then her research brought her to read countless scientific papers and to interview dozens of experts in various fields of study, including molecular biochemistry, epidemiology and neuroscience. What Marta discovered shattered her long-held beliefs about aging and longevity. A strong support network of family and friends, she learned, lowers mortality risk by about 45 percent, while exercise only lowers it by about 23 percent. Volunteering your free time lowers it by 22 percent or so, while certain health fads like turmeric haven’t been shown to help at all. These revelations led Marta Zaraska to a simple conclusion: In addition to healthy nutrition and physical activity, deepening friendships, practicing empathy and contemplating your purpose in life can improve your lifespan. Shermer and Zaraska also discuss: diet, nutrition, and supplements: what works, what doesn’t, and what about meat? exercise: how much, what type, and when? the causal mechanisms behind how relationships and marriage effect health, how friendships and community affect longevity, how religion makes people healthier and longer lived, why we need others and why handshakes and hugs will return after COVID-19, the harmful effects of loneliness and isolation, the deleterious effects of stress, and how leading a purposeful and meaningful life leads to longevity. Marta Zaraska is a Canadian-Polish science journalist. She has written about nutrition and psychology for the Washington Post, Scientific American, The Atlantic, The Los Angeles Times, New Scientist, and several other publications. She is the author of Meathooked: The History and Science of Our 2.5-Million-Year Obsession with Meat (Basic Books, 2016), which has been translated into Japanese, Korean, simplified Chinese, Spanish and Polish, and chosen by the journal Nature as one of “the best science picks” in March 2016. Meathookedhas also been praised in The Wall Street Journal, Discover Magazine, Time, The Washington Post, Kirkus Reviews, Natural History Magazine, etc. She has also contributed a chapter to the recently published The Reducetarian Solution (TarcherPerigee, 2017) alongside Mark Bittman, Michael Shermer, and Peter Singer.

136. Gad Saad — The Parasitic Mind: How Infectious Ideas Are Killing Common Sense

136. Gad Saad — The Parasitic Mind: How Infectious Ideas Are Killing Common Sense

There’s a war against truth and if we don’t win it, intellectual freedom will be a casualty. The West’s commitment to freedom, reason, and true liberalism has never been more seriously threatened than it is today by the stifling forces of political correctness. Dr. Gad Saad exposes the bad ideas—what he calls “idea pathogens”—that are killing common sense and rational debate. Incubated in our universities and spread through the tyranny of political correctness, these ideas are endangering our most basic freedoms—including freedom of thought and speech. The danger is grave, but as Dr. Saad shows, politically correct dogma is riddled with logical fallacies. We have powerful weapons to fight back with—if we have the courage to use them. A provocative guide to defending reason and intellectual freedom and a battle cry for the preservation of our fundamental rights, The Parasitic Mind will be the most controversial and talked-about book of the year. Shermer and Saad discuss: which idea pathogens are the most dangerous, the analogy between biological and ideological parasites, the origin of political correctness and how it was corrupted, identity politics and how it perpetrates bigotry, racism, and misogyny, the psychology of victimhood status (why would anyone want to be a victim?), virtue signaling and why it isn’t virtuous, why social justice is injustice, social justice warriors as sneaky fuckers, the corruption of postmodernism, which began as a form of rational skepticism, Islamophobia, diversity, inclusion and equity, safe spaces, microaggressions, trigger warnings, What is liberalism, anyway? the paradox of tolerance, the dual search for freedom and truth, free speech as the foundation of all other rights, Ostrich Parasitic Syndrome, Collective Munchausen Syndrome by Proxy, nomological networks of cumulative evidence in the quest for truth, and how big a problem are we really facing? Gad Saad, Ph.D. (Montreal, Canada), host of the popular YouTube show The Saad Truth and blogger for Psychology Today, is a professor of marketing at the John Molson School of Business at Concordia University. He holds the Concordia University Research Chair in Evolutionary Behavioral Sciences and Darwinian Consumption and is the author of The Evolutionary Bases of Consumption, plus numerous scientific papers.

135. Paul Halpern — Synchronicity: The Epic Quest to Understand the Quantum Nature of Cause and Effect

135. Paul Halpern — Synchronicity: The Epic Quest to Understand the Quantum Nature of Cause and Effect

Does the universe have a speed limit? If not, some effects could happen at the same instant as the actions that caused them — and some effects, ludicrously, might even happen before their causes. By one hundred years ago, it seemed clear that the speed of light was the fastest possible speed. Causality was safe. And then quantum mechanics happened, introducing spooky connections that seemed to circumvent the law of cause and effect. Inspired by the new physics, psychologist Carl Jung and physicist Wolfgang Pauli explored a concept called synchronicity, a weird phenomenon they thought could link events without causes. Synchronicity tells that sprawling tale of insight and creativity, and asks where these ideas — some plain crazy, and others crazy powerful — are taking the human story next. Shermer and Halpern discuss: Model-Dependent Realism, the idea from Stephen Hawking and Leonard Mlodinow that our understanding of nature depends on the model we apply to it, and that we cannot define science as an asymptotic curve toward Truth, from Newton to Einstein to Quantum Physics, Platonic ideals/idealism, Is the universe mathematical? Where/what are “laws of nature”? What is gravity? What is causality and how is it determined? quantum entanglement and what it says about our understanding of causality, Bell’s inequality, backward causality, Hume’s “constant conjunction” definition of causality and it’s limitations, Hume’s “counterfactual” theory of causality, Bogus mechanisms of causality: impetus, ether, energy fields, ESP, The friendship of Wolfgang Pauli and Carl Jung, Jungian archetypes and how scientists think about them, God, religion, and spirituality. Paul Halpern is a professor of physics at the University of the Sciences in Philadelphia and the author of sixteen popular science books, including The Quantum Labyrinth and Einstein’s Dice and Schrödinger’s Cat. He is the recipient of a Guggenheim fellowship and is a fellow of the American Physical Society. He lives near Philadelphia, Pennsylvania.
