Extraterrestrial Intelligence and Human Imagination
by John TraphaganThe search for extraterrestrial intelligence (SETI) represents one of the most significant crossroads at which the assumptions and methods of scientific inquiry come into direct contact with--and in many cases conflict with--those of religion. Indeed, at the core of SETI is the same question that motivates many interested in religion: What is the place of humanity in the universe? Both scientists involved with SETI (and in other areas) and those interested in and dedicated to some religious traditions are engaged in contemplating these types of questions, even if their respective approaches and answers differ significantly. This book explores this intersection with a focus on three core points: 1) the relationship between science and religion as it is expressed within the framework of SETI research, 2) the underlying assumptions, many of which are tacitly based upon cultural values common in American society, that have shaped the ways in which SETI researchers have conceptualized the nature of their endeavor and represented ideas about the potential influence contact might have on human civilization, and 3) what sort of empirical evidence we might be able to access as a way of thinking about the social impact that contact with alien intelligence might have for humanity, from both religious and cultural perspectives. The book developed as a result of a course the author teaches at the University of Texas at Austin: Religion, Science, and the Search for Extraterrestrial Intelligence.
Extraterrestrial Languages (The\mit Press Ser.)
by Daniel OberhausIf we send a message into space, will extraterrestrial beings receive it? Will they understand?The endlessly fascinating question of whether we are alone in the universe has always been accompanied by another, more complicated one: if there is extraterrestrial life, how would we communicate with it? In this book, Daniel Oberhaus leads readers on a quest for extraterrestrial communication. Exploring Earthlings' various attempts to reach out to non-Earthlings over the centuries, he poses some not entirely answerable questions: If we send a message into space, will extraterrestrial beings receive it? Will they understand? What languages will they (and we) speak? Is there not only a universal grammar (as Noam Chomsky has posited), but also a grammar of the universe? Oberhaus describes, among other things, a late-nineteenth-century idea to communicate with Martians via Morse code and mirrors; the emergence in the twentieth century of SETI (the search for extraterrestrial intelligence), CETI (communication with extraterrestrial intelligence), and finally METI (messaging extraterrestrial intelligence); the one-way space voyage of Ella, an artificial intelligence agent that can play cards, tell fortunes, and recite poetry; and the launching of a theremin concert for aliens. He considers media used in attempts at extraterrestrial communication, from microwave systems to plaques on spacecrafts to formal logic, and discusses attempts to formulate a language for our message, including the Astraglossa and two generations of Lincos (lingua cosmica).The chosen medium for interstellar communication reveals much about the technological sophistication of the civilization that sends it, Oberhaus observes, but even more interesting is the information embedded in the message itself. In Extraterrestrial Languages, he considers how philosophy, linguistics, mathematics, science, and art have informed the design or limited the effectiveness of our interstellar messaging.
Extraterrestrial Life: We are not alone
by Antonino Del PopoloAre we alone in the universe? This ancient question remains unanswered, but we are inching closer to finding out. Since the 1970s, probes have explored various objects in our solar system, revealing no advanced civilizations beyond Earth. However, bacterial life likely existed on Mars and might still exist today. Venus, though a scorching hellscape, could host bacterial life in its atmosphere. Some moons of gas giants are believed to harbor underground oceans potentially capable of supporting life. The greatest hopes for discovering life lie in the myriad of exoplanets in our galaxy and beyond, the first of which was discovered in 1995. This discovery revolutionized our understanding, showing that planets are common, with each star often hosting one or more. This significantly increases the likelihood of both microscopic life and advanced civilizations. While not all planets are suitable for life, billions of habitable planets exist in our galaxy alone, some even classified as super-habitable, possessing conditions more favorable for life than Earth. Current and future space telescopes aim to study these planets' atmospheres, searching for life-producing molecules. One such molecule, produced exclusively by life, has already been detected on a discovered planet. Despite extensive searches, no signals from other civilizations have been found, but this doesn't rule out their existence. Recent studies based on star formation, the prevalence of planets, and the potential for life-supporting conditions suggest that technological civilizations have certainly existed in the Universe. The next decade will be crucial in answering the question: are we alone?
Extraterrestrial Seismology
by Vincent C. H. Tong Rafael A. GarcíaSeismology is a highly effective tool for investigating the internal structure of the Earth. Similar techniques have also successfully been used to study other planetary bodies (planetary seismology), the Sun (helioseismology), and other stars (asteroseismology). Despite obvious differences between stars and planetary bodies, these disciplines share many similarities and together form a coherent field of scientific research. This unique book takes a transdisciplinary approach to seismology and seismic imaging, reviewing the most recent developments in these extraterrestrial contexts. With contributions from leading scientists, this timely volume systematically outlines the techniques used in observation, data processing, and modelling for asteroseismology, helioseismology, and planetary seismology, drawing comparisons with seismic methods used in geophysics. Important recent discoveries in each discipline are presented. With an emphasis on transcending the traditional boundaries of astronomy, solar, planetary and Earth sciences, this novel book is an invaluable resource and reference for undergraduates, postgraduates and academics.
Extraterrestrial: The First Sign of Intelligent Life Beyond Earth
by Avi LoebHarvard’s top astronomer lays out his controversial theory that our solar system was recently visited by advanced alien technology from a distant star. In late 2017, scientists at a Hawaiian observatory glimpsed an object soaring through our inner solar system, moving so quickly that it could only have come from another star. Avi Loeb, Harvard’s top astronomer, showed it was not an asteroid; it was moving too fast along a strange orbit, and left no trail of gas or debris in its wake. There was only one conceivable explanation: the object was a piece of advanced technology created by a distant alien civilization. In Extraterrestrial, Loeb takes readers inside the thrilling story of the first interstellar visitor to be spotted in our solar system. He outlines his controversial theory and its profound implications: for science, for religion, and for the future of our species and our planet. A mind-bending journey through the furthest reaches of science, space-time, and the human imagination, Extraterrestrial challenges readers to aim for the stars—and to think critically about what’s out there, no matter how strange it seems. <P><P> <b>A New York Times Bestseller</b>

Extraterrestrials (The MIT Press Essential Knowledge Series)
by Wade RoushAre we alone in the universe? If not, where is everybody? An engaging exploration of one of the most important unsolved problems in science. Everything we know about how planets form and how life arises suggests that human civilization on Earth should not be unique. We ought to see abundant evidence of extraterrestrial activity—but we don't. Where is everybody? In this volume in the MIT Press Essential Knowledge series, science and technology writer Wade Roush examines one of the great unsolved problems in science: is there life, intelligent or otherwise, on other planets? This paradox (they're bound to be out there; but where are they?), first formulated by the famed physicist Enrico Fermi, has fueled decades of debate, speculation, and, lately, some actual science. Roush lays out the problem in its historical and modern-day context and summarizes the latest thinking among astronomers and astrobiologists. He describes the long history of speculation about aliens (we've been debating the idea for thousands of years); the emergence of SETI (the Search for Extraterrestrial Intelligence) as a scientific discipline in the 1960s, and scientists' use of radio and optical techniques to scan for signals; and developments in astrobiology (the study of how life might arise in non-Earth like environments) and exoplanet research (the discovery of planets outside our solar system). Finally, he discusses possible solutions to the Fermi Paradox and suggests way to refocus SETI work that might increase the chances of resolving the paradox—and finding extraterrestrials.
Extraterrestrische Maschinen: Auf der Suche nach außerirdischer Intelligenz
by Wilfried DomainkoIn diesem Buch wird die Suche nach extraterrestrischen Strukturen diskutiert, die möglicherweise künstlichen Ursprungs sind. Die Fahndung nach künstlichen, extraterrestrischen Objekten wird jedoch durch die extrem vielfältigen Erscheinungsformen von natürlichen Himmelkörpern erschwert. Trotzdem ist die gezielte Suche nach außerirdischen Maschinen von riesigen Ausmaßen eine Möglichkeit, extraterrestrische Intelligenz zu entdecken. Tatsächlich besteht die Möglichkeit, einige Beobachtungen von außergewöhnlichen Himmelsobjekten entweder im Zusammenhang mit exotischen natürlichen Phänomenen oder aber als solche Technologiesignaturen zu deuten. Extraterrestrische Maschinen könnten technologisch viel fortschrittlicher sein als ihre irdischen Gegenstücke. Im Rahmen des zweiten Erklärungsansatzes könnten modifizierte Sterne als stellare Maschinen dienen, ganze Planeten nach den Bedürfnissen ihrer Bewohner umgestaltet werden oder gigantische Megastrukturen ihre Heimatsterne verdunkeln. Auch in unserem Sonnensystem wären Signaturen von extraterrestrischen Maschinen denkbar. Entsprechend könnten Beobachtungen von einigen sich bewegenden Himmelsobjekten mitunter im Zusammenhang mit interstellaren Raumsonden oder extraterrestrischem Weltraumschrott interpretiert werden. Neben der Vorstellung von möglichen beobachteten Technologiesignaturen und deren natürlichen und künstlichen Erklärungsmodellen, werden in diesem Buch auch verwandte irdische Technikvorhaben mit den entsprechenden Beobachtungen verglichen. In diesem Zusammenhang könnte das Auffinden von extraterrestrischen Maschinen sogar die menschliche Technologieentwicklung verändern.

Extreme Conservation: Life at the Edges of the World
by Joel Berger"Extraordinary. . . . Berger is a hero of biology who deserves the highest honors that science can bestow."—Tim Flannery, New York Review of Books On the Tibetan Plateau, there are wild yaks with blood cells thinner than those of horses’ by half, enabling the endangered yaks to survive at 40 below zero and in the lowest oxygen levels of the mountaintops. But climate change is causing the snow patterns here to shift, and with the snows, the entire ecosystem. Food and water are vaporizing in this warming environment, and these beasts of ice and thin air are extraordinarily ill-equipped for the change. A journey into some of the most forbidding landscapes on earth, Joel Berger’s Extreme Conservation is an eye-opening, steely look at what it takes for animals like these to live at the edges of existence. But more than this, it is a revealing exploration of how climate change and people are affecting even the most far-flung niches of our planet. Berger’s quest to understand these creatures’ struggles takes him to some of the most remote corners and peaks of the globe: across Arctic tundra and the frozen Chukchi Sea to study muskoxen, into the Bhutanese Himalayas to follow the rarely sighted takin, and through the Gobi Desert to track the proboscis-swinging saiga. Known as much for his rigorous, scientific methods of developing solutions to conservation challenges as for his penchant for donning moose and polar bear costumes to understand the mindsets of his subjects more closely, Berger is a guide par excellence. He is a scientist and storyteller who has made his life working with desert nomads, in zones that typically require Sherpas and oxygen canisters. Recounting animals as charismatic as their landscapes are extreme, Berger’s unforgettable tale carries us with humor and expertise to the ends of the earth and back. But as his adventures show, the more adapted a species has become to its particular ecological niche, the more devastating climate change can be. Life at the extremes is more challenging than ever, and the need for action, for solutions, has never been greater.

Extreme Lebensräume: Wie Mikroben unseren Planeten erobern
by Skander Elleuche Claudia StyrskyIst Leben in heißer Säure oder in seifigen Flüssen vorstellbar? Wie tot ist das Tote Meer tatsächlich? Und welche Lebewesen frieren bereits bei 60 °C? Das Buch nimmt den Leser mit auf eine Reise zu den undenkbarsten ökologischen Nischen unseres Planeten und ihren Herrschern. In den faszinierendsten Habitaten geben mikroskopisch kleine Organismen den Takt an: Sie besiedeln das kälteste Packeis, bezwingen die tiefste Tiefsee und die heißesten Quellen und trotzen sogar den salzigsten Seen. Selbst durch Katastrophen oder die Industrialisierung entstandene Lebensräume wie der ölbelastete Boden der Meere, vergiftete Industrieabwässer oder durch radioaktive Strahlung verseuchte Tümpel können diese kleinen Überlebenskünstler nicht aufhalten. Sie sind die Extremophilen („die das Extreme lieben“). Aufgrund ihrer enormen Anpassungsfähigkeit und ihres Talents, kaum vorstellbare Lebensräume zu erobern, spielen derartige Mikroben heute auch in der Astrobiologie und in der industriellen Biotechnologie wichtige Rollen.

And delve into how scientists are using what they know about aged plants and animals to research how we can promote longevity in humans.
Extreme Measures: The Ecological Energetics of Birds and Mammals
by Brian K. McNabAlong with reproduction, balancing energy expenditure with the limits of resource acquisition is essential for both a species and a population to survive. But energy is a limited resource, as we know well, so birds and mammals—the most energy-intensive fauna on the planet—must reduce energy expenditures to maintain this balance, some taking small steps, and others extreme measures. Here Brian K. McNab draws on his over sixty years in the field to provide a comprehensive account of the energetics of birds and mammals, one fully integrated with their natural history. McNab begins with an overview of thermal rates—much of our own energy is spent maintaining our 98.6?F temperature—and explains how the basal rate of metabolism drives energy use, especially in extreme environments. He then explores those variables that interact with the basal rate of metabolism, like body size and scale and environments, highlighting their influence on behavior, distribution, and even reproductive output. Successive chapters take up energy and population dynamics and evolution. A critical central theme that runs through the book is how the energetic needs of birds and mammals come up against rapid environmental change and how this is hastening the pace of extinction.
