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.

15. Donald Prothero & Timothy Callahan — UFOs, Chemtrails, and Aliens: What Science Says

15. Donald Prothero & Timothy Callahan — UFOs, Chemtrails, and Aliens: What Science Says

UFOs. Aliens. Strange crop circles. Giant figures scratched in the desert surface along the coast of Peru. The amazing alignment of the pyramids. Strange lines of clouds in the sky. The paranormal is alive and well in the American cultural landscape. In UFOs, Chemtrails, and Aliens, Don Prothero and Tim Callahan explore why such demonstrably false beliefs thrive despite decades of education and scientific debunking. Employing the ground rules of science and the standards of scientific evidence, Prothero and Callahan discuss a wide range of topics including the reliability of eyewitness testimony, psychological research into why people want to believe in aliens and UFOs, and the role conspiratorial thinking plays in UFO culture. They examine a variety of UFO sightings and describe the standards of evidence used to determine whether UFOs are actual alien spacecraft. Finally, they consider our views of aliens and the strong cultural signals that provide the shapes and behaviors of these beings. While their approach is firmly based in science, Prothero and Callahan also share their personal experiences of Area 51, Roswell, and other legendary sites, creating a narrative that is sure to engross both skeptics and believers.

14. Dr. Nancy Segal — Twin Mythconceptions: False Beliefs, Fables, and Facts about Twins

14. Dr. Nancy Segal — Twin Mythconceptions: False Beliefs, Fables, and Facts about Twins

Dr. Nancy Segal, the world’s leading expert on twins, has a new book that sheds light on over 70 commonly held ideas and beliefs about the origins and development of identical and fraternal twins. Using the latest scientific findings from psychology, psychiatry, biology, and education, Dr. Segal separates fact from fiction. Each idea about twins is described, followed by both a short answer about the truth, and then a longer, more detailed explanation. Coverage includes embryology of twins, twin types, intellectual growth, personality traits, sexual orientation of twins, marital relationships, epigenetic analyses, the frequency of different twin types and the varieties of polar body twin pairs. This book, and Salon with Dr. Segal, will inform and entertain behavioral and life science researchers, health professionals, twins, parents of twins, and anyone interested in the fascinating topic of twins and what they can teach us about human nature. Dr. Segal earned her Ph.D. in the Social Sciences and Behavioral Sciences from the University of Chicago. From 1982-1991 she was a post-doctoral fellow and research associate at the University of Minnesota, affiliated with the well-known Minnesota Study of Twins Reared Apart. She is currently Professor of Psychology at CSU Fullerton and Director of the Twin Studies Center, which she founded in 1991. Dr. Segal has authored over 200 scientific articles and book chapters, as well as several books on twins. Her previous book, Born Together-Reared Apart: The Landmark Minnesota Twin Study (2012, Harvard University Press) won the 2013 William James Book Award from the American Psychological Association. Her other books include Someone Else’s Twin: The True Story of Babies Switched at Birth (2011), Indivisible by Two: Lives of Extraordinary Twins (2007) and Entwined Lives: Twins and What They Tell Us About Human Behavior (2000).

13. Dr. Walter Scheidel — The Great Leveler: Violence and the History of Inequality from the Stone Age to the 21st Century

13. Dr. Walter Scheidel — The Great Leveler: Violence and the History of Inequality from the Stone Age to the 21st Century

Are mass violence and catastrophes the only forces that can seriously decrease economic inequality? To judge by thousands of years of history, the answer is yes. Tracing the global history of inequality from the Stone Age to today, the Stanford University historian Walter Scheidel shows that inequality never dies peacefully. Inequality declines when carnage and disaster strike and increases when peace and stability return. The Great Leveler is the first book to chart the crucial role of violent shocks in reducing inequality over the full sweep of human history around the world. Ever since humans began to farm, herd livestock, and pass on their assets to future generations, economic inequality has been a defining feature of civilization. Over thousands of years, only violent events have significantly lessened inequality. The “Four Horsemen” of leveling—mass-mobilization warfare, transformative revolutions, state collapse, and catastrophic plagues—have repeatedly destroyed the fortunes of the rich. Scheidel identifies and examines these processes, from the crises of the earliest civilizations to the cataclysmic world wars and communist revolutions of the twentieth century. Today, the violence that reduced inequality in the past seems to have diminished, and that is a good thing. But it casts serious doubt on the prospects for a more equal future. An essential contribution to the debate about inequality, The Great Leveler provides important new insights about why inequality is so persistent—and why it is unlikely to decline anytime soon.

11. Dr. Andrew Shtulman — Scienceblind: Why Our Intuitive Theories About the World Are So Often Wrong

11. Dr. Andrew Shtulman — Scienceblind: Why Our Intuitive Theories About the World Are So Often Wrong

Why do we catch colds? What causes seasons to change? And if you fire a bullet from a gun and drop one from your hand, which bullet hits the ground first? In a pinch we almost always get these questions wrong. Worse, we regularly misconstrue fundamental qualities of the world around us. In Scienceblind, cognitive and developmental psychologist Dr. Andrew Shtulman, a professor of psychology and cognitive science at Occidental College, where he directs the Thinking Lab, shows that the root of our misconceptions lies in the theories about the world we develop as children. They’re not only wrong, they close our minds to ideas inconsistent with them, making us unable to learn science later in life. So how do we get the world right? We must dismantle our intuitive theories and rebuild our knowledge from its foundations. The reward won’t just be a truer picture of the world, but clearer solutions to many controversies—around vaccines, climate change, or evolution—that plague our politics today.

10. Dr. Carol Tavris — Mistakes Were Made (But Not by Me)

Why is it so hard to say “I made a mistake”—and really believe it? Social psychologist Dr. Carol Tavris, one of the most influential thinkers and writers of our time, explores in dialogue with Michael Shermer cognitive dissonance and what happens when we make mistakes, cling to outdated attitudes, or mistreat other people—we must calm the cognitive dissonance that jars our feelings of self-worth. And so, unconsciously, we create fictions that absolve us of responsibility, restoring our belief that we are smart, moral, and right—a belief that often keeps us on a course that is dumb, immoral, and wrong. Backed by years of research, Mistakes Were Made (But Not by Me) offers a fascinating explanation of self-justification—how it works, the damage it can cause, and how we can overcome it. The updated edition of the book features new examples and concludes with an extended discussion of how we can live with dissonance, learn from it, and perhaps, eventually, forgive ourselves.

9. Gary Taubes — The Case Against Sugar

9. Gary Taubes — The Case Against Sugar

Among Americans, diabetes is more prevalent today than ever; obesity is at epidemic proportions; nearly 10% of children are thought to have nonalcoholic fatty liver disease. And sugar is at the root of these, and other, critical society-wide, health-related problems. With his signature command of both science and straight talk, Gary Taubes delves into Americans’ history with sugar: its uses as a preservative, as an additive in cigarettes, the contemporary overuse of high-fructose corn syrup. He explains what research has shown about our addiction to sweets. He clarifies the arguments against sugar, corrects misconceptions about the relationship between sugar and weight loss; and provides the perspective necessary to make informed decisions about sugar as individuals and as a society. This is a groundbreaking and eye opening expose that makes the convincing case that sugar is the tobacco of the new millennium, backed by powerful lobbies, entrenched in our lives, and utterly addicting, making us all very sick. As Katie Couric says, “This is required reading for not only ever parent, but every American.” Gary Taubes is the New York Times bestselling author of Good Calories, Bad Calories and Why We Get Fat. His writing has appeared in the New York Times magazine, The Atlantic, and Esquire.
