Are Parallel Universes and Extra Dimensions Real?

Are Parallel Universes and Extra Dimensions Real?

Our books, our movies—our imaginations—are obsessed with extra dimensions, alternate timelines, and the sense that all we see might not be all there is. In short, we can’t stop thinking about the multiverse. As it turns out, physicists are similarly captivated.

In The Allure of the Multiverse, physicist Paul Halpern tells the epic story of how science became besotted with the multiverse, and the controversies that ensued. The questions that brought scientists to this point are big and deep: Is reality such that anything can happen, must happen? How does quantum mechanics “choose” the outcomes of its apparently random processes? And why is the universe habitable? Each question quickly leads to the multiverse. Drawing on centuries of disputation and deep vision, from luminaries like Nietzsche, Einstein, and the creators of the Marvel Cinematic Universe, Halpern reveals the multiplicity of multiverses that scientists have imagined to make sense of our reality. Whether we live in one of many different possible universes, or simply the only one there is, might never be certain. But Halpern shows one thing for sure: how stimulating it can be to try to find out.

Shermer and Halpern discuss: definitions of universe and types of multiverses • Is the multiverse science, metaphysics, or faith? • theists claim the “multiverse” is just handwaving around the God answer • many worlds interpretation of quantum mechanics? • inflationary and Darwinian cosmology • infinity and eternity • multiple dimensions • string theory • cyclical universes • Big Bounce • Anthropic Principle (weak, strong, participatory) • time travel • sliding doors, contingency, and the multiverse.

Dr. Paul Halpern is the author of 18 popular science books, exploring the subjects of space, time, higher dimensions, dark energy, dark matter, exoplanets, particle physics, and cosmology. The recipient of a Guggenheim Fellowship, a Fulbright Scholarship, and an Athenaeum Literary Award, he has contributed to Nature, Physics Today, Aeon, NOVA’s “The Nature of Reality” physics blog, and Forbes “Starts with a Bang!” He has appeared on numerous radio and television shows including “Future Quest,” “Science Friday,” “Radio Times,” “Coast to Coast AM,” “The Simpsons 20thAnniversary Special,” and C-SPAN’s “BookTV.” He appeared previously on the show for his book Synchronicity: The Epic Quest to Understand the Quantum Nature of Cause and Effect. His new book, The Allure of the Multiverse, describes the controversial history of higher dimensional and parallel universe schemes in science and culture.

How to Think About Souls, UFOs, Time, Belief, and Everything

How to Think About Souls, UFOs, Time, Belief, and Everything

From precognitive dreams and telepathic visions to near-death experiences, UFO encounters, and beyond, so-called impossible phenomena are not supposed to happen. But they do happen—all the time. Jeffrey J. Kripal asserts that the impossible is a function not of reality but of our everchanging assumptions about what is real. How to Think Impossibly invites us to think about these fantastic (yet commonplace) experiences as an essential part of being human, expressive of a deeply shared reality that is neither mental nor material but gives rise to both. Thinking with specific individuals and their extraordinary experiences in vulnerable, open, and often humorous ways, Kripal interweaves humanistic and scientific inquiry to foster an awareness that the fantastic is real, the supernatural is super natural, and the impossible is possible. Jeffrey J. Kripal holds the J. Newton Rayzor Chair in Philosophy and Religious Thought at Rice University. He is the author of numerous books, including The Superhumanities: Historical Precedents, Moral Objections, New Realities, The Flip: Epiphanies of Mind and the Future of Knowledge, Authors of the Impossible: The Paranormal and the Sacred, Esalen: America and the Religion of No Religion, Mutants and Mystics: Science Fiction, Superhero Comics, and the Paranormal, and just published, also by the University of Chicago Press, How to Think Impossibly: About Souls, UFOs, Time, Belief, and Everything Else.

The Science of Disbelief: Understanding Atheism and the Evolution of Religion

The Science of Disbelief: Understanding Atheism and the Evolution of Religion

In Disbelief: The Origins of Atheism in a Religious Species, Will Gervais explores the interconnected nature of religious belief and atheism in human psychology. Gervais proposes that understanding religion requires solving two evolutionary puzzles: the Puzzle of Faith, examining how Homo sapiens became uniquely religious, and the Puzzle of Atheism, investigating how disbelief exists within this religious species. This approach yields a comprehensive theory explaining both faith and atheism, shedding light on humanity’s religious evolution and the current trend of abandoning belief. Gervais draws on cognitive science, cultural evolution, and evolutionary psychology to challenge existing theories of religion. Will Gervais, PhD, is a prominent cultural evolutionary psychologist specializing in the scientific study of atheism. His research, featured in major media outlets, bridges cultural evolution, evolutionary psychology, and cognitive science. Gervais’s interdisciplinary work has earned him recognition as a Rising Star by the Association for Psychological Science and garnered awards from the American Psychological Association and the Foundation for Personality and Social Psychology. In Disbelief, Gervais employs accessible prose and compelling examples to explain humanity’s religious origins, the shift away from faith, and strategies for navigating religious divides in our culturally evolved landscape. Shermer and Gervais explore the nature of religion, various belief systems, and atheism’s prevalence and perception. They delve into the cognitive foundations of faith, evolutionary perspectives on religion, and its historical and societal roles. The discussion covers the adaptive nature of belief, religious diversity, and the impact of religion on personal and social well-being. They also consider the future of belief systems and potential alternatives to traditional religion.

Unmasking the Unknown: UFOs, Alien Tech, and Military Secrets?

Unmasking the Unknown: UFOs, Alien Tech, and Military Secrets?

Extraordinary claims require extraordinary proof. It’s no different when it comes to UFO frenzy. There is a need to separate fact from fiction in UAP claims. In this episode, Shermer delves into the growing interest in UAPs (formerly UFOs), especially in light of UFOlogist Lue Elizondo’s book Imminent. Elizondo claims the U.S. government has long been aware of extraterrestrial intelligence, backed by reports of unidentified craft surveilling military sites. The episode explores these bold assertions and the tension between believers and skeptics, including scientists like Avi Loeb and institutions like the Department of Defense, which have disputed such claims. Listeners interested in extraterrestrial intelligence, UFOs, and government secrecy will find this discussion compelling. Shermer reflects on historical UFO figures like Bob Lazar and Travis Walton, questioning their credibility while exploring the widespread belief in imminent “disclosure” of alien contact. Through interviews with experts and analysis of various UAP phenomena, the episode challenges listeners to discern fact from fiction, offering an intriguing examination of what could be humanity’s most profound discovery.

Are We Confused About Social Justice? (Helen Pluckrose)

Are We Confused About Social Justice? (Helen Pluckrose)

The stated goals of diversity, equity, and inclusion programs are often reasonable, if not noble—to create a more welcoming and inclusive environment for all. Yet, as more and more people are discovering, DEI as commonly practiced isn’t a natural extension of past civil rights movements or an ethical framework for opposing discrimination on the grounds of race, sex, etc. Rather, it is inextricably connected with an illiberal and authoritarian ideology—Critical Social Justice—that demands adherence to its tenets and punishes any dissent from its dogma. Even the mildest questions about Critical Social Justice claims—that all white people are racists, that all underrepresented minorities are oppressed, that sex and gender differences have no biological basis, that censorship is a necessary good—are regularly met by DEI trainers and HR officers with pat commands: “Educate yourself,” “Do the work,” “Listen and learn.” At work, raises, promotions, and future employment often depend on our nodding approval of such claims. At school, grades, nominations, and awards are often contingent upon our active agreement with these beliefs. In our daily lives, Critical Social Justice ideology poses a genuine threat not only to our fundamental rights but also to the future of our democratic systems, but if we suggest this, we risk being canceled or shunned by community members. When facing a choice between silent submission and risky if ethical opposition, what is a person to do? While a growing number of groups concerned about the nature of Critical Social Justice have begun to attack it from the top down through legal, financial, and political means, The Counterweight Handbook takes a decidedly different and novel approach. It works from the bottom up and is written to empower individuals who wish to combat Critical Social Justice in their personal and professional lives. Based on the author’s years of experience studying, exposing, and fighting Critical Social Justice ideology and advising individuals and organizations struggling with it, The Counterweight Handbook is designed to help people address Critical Social Justice problems in the most ethical and effective way possible. It not only offers principled responses to the main claims of Critical Social Justice but also teaches individuals what to do when they are asked to affirm beliefs they do not hold, undergo training in an ideology they cannot support, or submit to antiscientific testing and retraining of their “unconscious” minds. In short, it is for all of us who believe in freedom of speech and conscience, who wish to push back against the hostile work and educational environments Critical Social Justice has created, and who want to stand up for our individual liberties and universal rights. Helen Pluckrose is a liberal political and cultural writer and was one of the founders of Counterweight. A participant in the Grievance Studies Affair probe that highlighted problems in Critical Social Justice scholarship, she is the coauthor of Cynical Theories and Social (In)justice. She lives in England and can be found on X @HPluckrose Shermer and Pluckrose discuss: origin of the problem • DEI and CRT • what it means to “Educate yourself,” “Do the work,” “Listen and learn.” • top-down vs. bottom-up counter measures • race reckoning • antiracism • gender ideology • decolonizing and dismantling • fragility • intersectionality • normativity • positionality • privilege • wokeness.

The Cultural History of Charles Fort and His Followers

The Cultural History of Charles Fort and His Followers

Charles Fort, a maverick writer, fascinated by bizarre occurrences like flying saucers, Bigfoot, and frogs raining from the sky, scanned newspapers and magazines for reports of anomalies, advancing a philosophy that saw science as a small part of a larger system where truth and falsehood constantly transformed. His work found a following of skeptics who questioned not only science but also the press, medicine, and politics, led by the adman and writer Tiffany Thayer, who founded the Fortean Society. Joshua Blu Buhs argues in Think to New Worlds that the Fortean movement provided tools to expand the imagination, explore the social order, and demonstrate power dynamics, inspiring science fiction writers, avant-garde modernists, and post-World War II flying saucer enthusiasts to uncover the hidden structures of reality in an ever-expanding universe filled with unexplained occurrences and visionary possibilities. Joshua Blu Buhs is a scholar of the overlap of politics, biology, and ecology in twentieth-century America and has written articles that have appeared in Isis, Environmental History, The World of Genetics, and Journal of the History of Biology. His PhD is in the history of science from Penn State. He is the author of Bigfoot: The Life and Times of a Legend and The Fire Ant Wars: Nature, Science, and Public Policy in Twentieth-Century America, both published by the University of Chicago Press. His new book is Think to New Worlds: The Cultural History of Charles Fort and His Followers. Shermer and Buhs discuss his research and writing on weird phenomena like Bigfoot, Charles Fort, Fortean followers, anomaly hunting, science fiction, UFOs, skeptics, and the cultural impact of Fortean ideas that blurred the boundaries between truth and falsehood, undermining expert authority and fueling conspiracies.

The Logic of Nuclear Policy: Deterrence and MAD Explained.

The Logic of Nuclear Policy: Deterrence and MAD Explained.

As if 2024 couldn't get any weirder, tensions in the Middle East have escalated with the United States sending one of our nuclear submarines to the Mediterranean as a deterrent signal to Iran that they better think twice about attacking Israel. That sub, the Ohio-class USS Georgia, carries non-nuclear cruise missiles. But 14 of our 18 Ohio-class submarines have nuclear-tipped ballistic missiles—each sub has in its belly the nuclear equivalent of all the bombs dropped in World War II. Multiply that by 14 and let your imagination be properly staggered. Meanwhile, Ukrainian forces have pushed into Russian territory and Putin is outraged at the invasion. How far can Ukraine go before Putin uses his battlefield tactical nukes in response? In this solo episode, Michael Shermer discusses the threat of nuclear annihilation and explores the evolutionary origins of our moral emotions and logic of deterrence based on game theory. Focus of the analysis: the need to reduce nuclear stockpiles and shifting the taboo from using to owning nuclear weapons.
