Explores fundamental philosophical and scientific questions about the nature of life, particularly in relation to the search for extraterrestrial life.
No scientific quest is as compelling as the search for the key to understand the universe—the elusive unified “Theory of Everything”—a theory so concise it could fit on a T-shirt. Lively and thought-provoking, Universe on a T-Shirt tells the fascinating story of the search for the Holy Grail of physics. Dan Falk places this intriguing story in its historical context, tracing the quest from ancient Greece to the breakthroughs of Newton, Maxwell, and Einstein, to the excitement over string theory and today’s efforts to merge quantum theory with general relativity. With as much emphasis on history as on science, Falk’s accessible approach is ideal for anyone intrigued by the advances in modern physics but still wondering what theoretical physicists are searching for, and why. Today’s physicists use sophisticated methods, but their goal—the search for simplicity—has not changed since the time of the ancient Greeks. Universe on a T-Shirt is filled with quirky personalities, brilliant minds, and bold ideas—high science and high drama. "An admirably concise and comprehensive overview of cosmology . . . [that] offers intriguing insights into the philosophic and personal outlooks motivating the scientists involved, from the ancient Greeks through Newton and Einstein . . . [and] Stephen Hawking and Ed Witten.”—Booklist
Bringing together the latest scientific advances and some of the most enduring subtle philosophical puzzles and problems, this book collects original historical and contemporary sources to explore the wide range of issues surrounding the nature of life. Selections ranging from Aristotle and Descartes to Sagan and Dawkins are organised around four broad themes covering classical discussions of life, the origins and extent of natural life, contemporary artificial life creations and the definition and meaning of 'life' in its most general form. Each section is preceded by an extensive introduction connecting the various ideas discussed in individual chapters and providing helpful background material for understanding them. With its interdisciplinary perspective, this fascinating collection is essential reading for scientists and philosophers interested in astrobiology, synthetic biology and the philosophy of life.
For millennia, shamans and philosophers, believers and nonbelievers, artists and scientists have tried to make sense of our existence by suggesting that everything is connected, that a mysterious Oneness binds us to everything else. People go to temples, churches, mosques, and synagogues to pray to their divine incarnation of Oneness. Following a surprisingly similar notion, scientists have long asserted that under Nature’s apparent complexity there is a simpler underlying reality. In its modern incarnation, this Theory of Everything would unite the physical laws governing very large bodies (Einstein’s theory of relativity) and those governing tiny ones (quantum mechanics) into a single framework. But despite the brave efforts of many powerful minds, the Theory of Everything remains elusive. It turns out that the universe is not elegant. It is gloriously messy. Overturning more than twenty-five centuries of scientific thought, award-winning physicist Marcelo Gleiser argues that this quest for a Theory of Everything is fundamentally misguided, and he explains the volcanic implications this ideological shift has for humankind. All the evidence points to a scenario in which everything emerges from fundamental imperfections, primordial asymmetries in matter and time, cataclysmic accidents in Earth’s early life, and duplication errors in the genetic code. Imbalance spurs creation. Without asymmetries and imperfections, the universe would be filled with nothing but smooth radiation. A Tear at the Edge of Creation calls for nothing less than a new "humancentrism" to reflect our position in the universal order. All life, but intelligent life in particular, is a rare and precious accident. Our presence here has no meaning outside of itself, but it does have meaning. The unplanned complexity of humankind is all the more beautiful for its improbability. It’s time for science to let go of the old aesthetic that labels perfection beautiful and holds that "beauty is truth." It’s time to look at the evidence without centuries of monotheistic baggage. In this lucid, down-to-earth narrative, Gleiser walks us through the basic and cutting-edge science that fueled his own transformation from unifier to doubter—a fascinating scientific quest that led him to a new understanding of what it is to be human.
Are we alone in the universe? Are the planets our playground to treat as we will, or do we have a responsibility to other creatures who may inhabit or use them? Do we have a right to dump trash in space or leave vehicles on Mars or the moon? How should we interact with other life forms? Encountering Life in the Universe examines the intersection of scientific research and society to further explore the ethics of how to behave in a universe where much is unknown. Taking contributions from notable experts in several fields, the editors skillfully introduce and develop a broad look at the moral questions facing humans on Earth and beyond. Major advances in biology, biotechnology, and medicine create an urgency to ethical considerations in those fields. Astrobiology goes on to debate how we might behave as we explore new worlds, or create new life in the laboratory, or interact with extraterrestrial life forms. Stimulated by new technologies for scientific exploration on and off the Earth, astrobiology is establishing itself as a distinct scientific endeavor. In what way can established philosophies provide guidance for the new frontiers opened by astrobiology research? Can the foundations of ethics and moral philosophy help answer questions about modifying other planets? Or about how to conduct experiments to create life in the lab or about? How to interact with organisms we might discover on another world? While we wait for the first echo that might indicate life beyond Earth, astobiologists, along with philosophers, theologians, artists, and the general public, are exploring how we might behave—even before we know for sure they are there. Encountering Life in the Universe is a remarkable resource for such philosophical challenges.
In a revolutionary new theory, Dr. Robert Foot of the University of Melbourne argues that meteorites composed of mirror matter could impact with the Earth without leaving any ordinary fragments. Indeed, the theory seems to provide a simple explanation for the puzzling Tunguska event--the blast which destroyed a huge area of Siberian forest in 1908. While scientists have attributed this explosion to an ordinary meteorite, no traces of such an object have ever been found. Moreover, there are frequent smaller such events, occurring on a yearly basis, which are even more puzzling. Foot's new book lays clear the scientific case for mirror matter. It describes the fascinating evidence for its existence including, astronomical observations suggesting that most of our galaxy is made from a new form of matter--dark matter. It explains puzzling Jupiter sized planets only a few million miles from their host star, and the mysterious slowing down of spacecraft in our solar system. Remarkably, it is also possible that Pluto might even be a mirror world, which would explain various anomalous features of its orbit. Perhaps the most important consequence of all this--if true--is the possibility of actually extracting the mirror matter from the Tunguska impact site and other such sites on earth. Invisible asteroids and other cosmic bodies made of a new form of matter may pose a threat to Earth, agrees a noted Australian physicist. But the mirror matter idea has not attracted a huge following among physicists. In a recent UPI article, Howard Georgi of Harvard University says, "Foot's ideas have not attracted a huge following in the community that cares about these things, perhaps because the problems they solve, while interesting, are not the most critical puzzles that we are wrestling with." Nevertheless, mirror matter, if it exists, would be a completely new type of material with a potentially huge commercial value. Its scientific value would be of no less importance. FROM THE BACK COVER Nearly 50 years ago it was discovered that the fundamental particles, such as the electron and proton, have `left-handed' interactions; they do not respect mirror symmetry. This experimental fact motivates the idea that a set of `mirror particles' exist. The left-handedness of the ordinary particles can then be balanced by the right-handedness of the mirror particles. In this way mirror reflection symmetry can exist but requires something profoundly new. It requires the existence of a completely new form of matter called `mirror matter'. Remarkably the mirror matter theory is capable of simply explaining a large number of contemporary puzzles in astrophysics and particle physics. The evidence ranges from observations suggesting that most of the matter in the Universe is invisible, to unexpected properties of ghostly particles called `neutrinos'. This book explains this fascinating theory and its evidence at a level accessible to the non-specialist.
Why do we exist? For centuries, this question was the sole province of religion and philosophy. But now science is ready to take a seat at the table. According to the prevailing scientific paradigm, the universe tends toward randomness; it functions according to laws without purpose, and the emergence of life is an accident devoid of meaning. But this bleak interpretation of nature is currently being challenged by cutting-edge findings at the intersection of physics, biology, neuroscience, and information theory—generally referred to as “complexity science.” Thanks to a new understanding of evolution, as well as recent advances in our understanding of the phenomenon known as emergence, a new cosmic narrative is taking shape: Nature’s simplest “parts” come together to form ever-greater “wholes” in a process that has no end in sight. In The Romance of Reality, cognitive neuroscientist Bobby Azarian explains the science behind this new view of reality and explores what it means for all of us. In engaging, accessible prose, Azarian outlines the fundamental misunderstanding of thermodynamics at the heart of the old assumptions about the universe’s evolution, and shows us the evidence that suggests that the universe is a “self-organizing” system, one that is moving toward increasing complexity and awareness. Cosmologist and science communicator Carl Sagan once said of humanity that “we are a way for the cosmos to know itself.” The Romance of Reality shows that this poetic statement in fact rests on a scientific foundation and gives us a new way to know the cosmos, along with a riveting vision of life that imbues existence with meaning—nothing supernatural required.
Astrophilosopy, Exotheology, and Cosmic Religion: Extraterrestrial Life in a Process Universe applies Alfred North Whitehead’s process philosophy and the associated process philosophies of Henri Bergson, Teilhard de Chardin, and others to the interdisciplinary layers of astrobiology, extraterrestrial life, and the impact of discovery. This collection, edited by Andrew M. Davis and Roland Faber, asks questions such as “How have process thinkers imagined universal creative evolution and its implications for philosophies, theologies, and religions beyond earth?” and “How might their claims as to the primacy of organism, temporality, novelty, value, and mind enrich current discussions and debates across disciplines?” As experts in their fields, the contributors are informed by, but not limited to, process conceptualities. The chapters not only advance recent discussions in astrobiology, cosmology, and evolution but also consider a constellation of philosophical topics, from shared extraterrestrial knowledge and values to the possibilities or limitations afforded by A.I. technology, the Fermi Paradox, the Drake Equation, and the increasing need to nurture the cosmic dimensions of theological and religious traditions.
"This is science writing as wonder and as inspiration." —The Wall Street Journal Wall Street Journal From one of the most influential scientists of our time, a dazzling exploration of the hidden laws that govern the life cycle of everything from plants and animals to the cities we live in. Visionary physicist Geoffrey West is a pioneer in the field of complexity science, the science of emergent systems and networks. The term “complexity” can be misleading, however, because what makes West’s discoveries so beautiful is that he has found an underlying simplicity that unites the seemingly complex and diverse phenomena of living systems, including our bodies, our cities and our businesses. Fascinated by aging and mortality, West applied the rigor of a physicist to the biological question of why we live as long as we do and no longer. The result was astonishing, and changed science: West found that despite the riotous diversity in mammals, they are all, to a large degree, scaled versions of each other. If you know the size of a mammal, you can use scaling laws to learn everything from how much food it eats per day, what its heart-rate is, how long it will take to mature, its lifespan, and so on. Furthermore, the efficiency of the mammal’s circulatory systems scales up precisely based on weight: if you compare a mouse, a human and an elephant on a logarithmic graph, you find with every doubling of average weight, a species gets 25% more efficient—and lives 25% longer. Fundamentally, he has proven, the issue has to do with the fractal geometry of the networks that supply energy and remove waste from the organism’s body. West’s work has been game-changing for biologists, but then he made the even bolder move of exploring his work’s applicability. Cities, too, are constellations of networks and laws of scalability relate with eerie precision to them. Recently, West has applied his revolutionary work to the business world. This investigation has led to powerful insights into why some companies thrive while others fail. The implications of these discoveries are far-reaching, and are just beginning to be explored. Scale is a thrilling scientific adventure story about the elemental natural laws that bind us together in simple but profound ways. Through the brilliant mind of Geoffrey West, we can envision how cities, companies and biological life alike are dancing to the same simple, powerful tune.
