In a 1950 conversation at Los Alamos, four world-class scientists generally agreed, given the size of the Universe, that advanced extraterrestrial civilizations must be present. But one of the four, Enrico Fermi, asked, "If these civilizations do exist, where is everybody?" Given the fact that there are perhaps 400 million stars in our Galaxy alone, and perhaps 400 million galaxies in the Universe, it stands to reason that somewhere out there, in the 14 billion-year-old cosmos, there is or once was a civilization at least as advanced as our own. Webb discusses in detail the 50 most cogent and intriguing solutions to Fermi's famous paradox.

Read the award-winning, critically acclaimed, multi-million-copy-selling science-fiction phenomenon – now a Netflix Original Series from the creators of Game of Thrones. Imagine the universe as a forest, patrolled by numberless and nameless predators. In this forest, stealth is survival – any civilisation that reveals its location is prey. Earth has. Now the predators are coming. Crossing light years, the Trisolarians will reach Earth in four centuries' time. But the sophons, their extra-dimensional agents and saboteurs, are already here. Only the individual human mind remains immune to their influence. This is the motivation for the Wallfacer Project, a last-ditch defence that grants four individuals almost absolute power to design secret strategies, hidden through deceit and misdirection from human and alien alike. Three of the Wallfacers are influential statesmen and scientists, but the fourth is a total unknown. Luo Ji, an unambitious Chinese astronomer, is baffled by his new status. All he knows is that he's the one Wallfacer that Trisolaris wants dead. Praise for The Three-Body Problem: 'Your next favourite sci-fi novel' Wired 'Immense' Barack Obama 'Unique' George R.R.

The Great Silence explores the multifaceted problem named after the great Italian physicist Enrico Fermi and his legendary 1950 lunchtime question "Where is everybody?" In many respects, Fermi's paradox is the richest and the most challenging problem for the entire field of astrobiology and the Search for ExtraTerrestrial Intelligence (SETI) studies. This book shows how Fermi's paradox is intricately connected with many fields of learning, technology, arts, and even everyday life. It aims to establish the strongest possible version of the problem, to dispel many related confusions, obfuscations, and prejudices, as well as to offer a novel point of entry to the many solutions proposed in existing literature. Ćirković argues that any evolutionary worldview cannot avoid resolving the Great Silence problem in one guise or another.

Paul Davies' The Eerie Silence: Searching For Ourselves in the Universe is an engaging and lucid guide to the 'Fermi Paradox' - why isn't the universe teeming with alien life? If aliens ever contact us, it will be the single most significant event in human history. And Paul Davies will be responsible for saying something back. For fifty years the Search for Extra-Terrestrial Intelligence has been scanning the skies. Now Davies, head of SETI's Post-Detection Task Group, with 'a rare talent for making physics mind-bogglingly vivid and exciting' (Times Higher Education), explores what the mysterious silence it has encountered could mean. Here he looks at exciting new ways to make contact with extra-terrestrial life. He considers what form advanced alien intelligence is likely to take if it exists. And more importantly, what exactly it would mean if it didn't - how extraordinary it would be if we were alone, to be human and here in this staggering, eerie silence... 'A magnificent cosmic tour of what might be out there in space' Sunday Times 'Rather wonderful' New Scientist 'Conveys excellently the fascination of the quest' The Times 'An authoritatively written, immensely clear, lay person's guide to the many things we don't know about the rest of the universe' Guardian Paul Davies is Director of the BEYOND Center for Fundamental Concepts in Science, and co-Director of the Cosmology Initiative, both at Arizona State University. An internationally-acclaimed physicist, writer and broadcaster, Davies is the author of some twenty award-winning books, including The Eerie Silence: Searching for Ourselves in the Universe, The Goldilocks Enigma: Why is the Universe Just Right for Life? and The Mind of God: Science and the Search for Ultimate Meaning.

In these lively and fascinating essays edited by theoretical physicist Jim Al-Khalili, scientists from around the world weigh in on the latest advances in the search for intelligent life in the universe and discuss just what that might look like. Since 2000, science has seen a surge in data and interest on several fronts related to E.T. (extraterrestrials); A.I. (artificial intelligence); and SETI (search for extraterrestrial intelligence). The debate has intensified over whether life exists outside our solar system, what that life would look like, and whether we’ll ever make contact. Included here are essays from a broad spectrum of the scientific community: cosmologists, astrophysicists, NASA planetary scientists, and geneticists, to name just a few, discussing the latest research and theories relating to alien life. Some of the topics include: If life exists somewhere in space, what are the odds that it evolves into something we would recognize as intelligent? What will space travel look like in the future, and will it all be done by cyborg technology? How long until we are ruled by robot overlords? (This is actually a serious consideration.) Are we simply a simulation in the mind of some supreme being, acting out a virtual reality game? For those who have ever wondered, Is there anybody out there? here are the latest theories and evidence that move us closer to answering that question.

The proper study of mankind is not merely Man, but Intelligence. 1 —Arthur C. Clarke, 1951 In the long-running television series “The X-Files,” the original Deep Throat said to FBI Special Agent Mulder that “there are those like yourself who believe in the existence of extraterrestrial life.” Ah, but that’s not the question. If extraterrestrial life exists, most of it may be in simpler forms comparable to the one-celled organisms of Earth biology. Finding such life would be fascinating for scientists, but may be of only passing interest to the general public. What intrigues the average citizen is the possibility of contact with extraterrestrial intelligence. We want to communicate with other sentient beings, learning what they know and telling them about ourselves. We want to ? nd out how they are like us and how they are different. Microorganisms don’t have a lot to say. There is another implication of contact that underlies this book: Intel- gent extraterrestrials might have an impact on our future. The information they send us—if any—might change our cultures. They could have c- scious intentions toward us, and possibly the technologies to reach us directly. Their intentions may be benign—or not. Our interest in alien minds is not new. The idea that intelligent beings exist beyond the Earth has been part of the Western intellectual tradition for more than 2000 years. Sometimes this belief was widespread; at other times, it was out of fashion.

“New Eyes on the Universe – Twelve Cosmic Mysteries and the Tools We Need to Solve Them” gives an up-to-date broad overview of some of the key issues in modern astronomy and cosmology. It describes the vast amount of observational data that the new generation of observatories and telescopes are currently producing, and how that data might solve some of the outstanding puzzles inherent in our emerging world view. Included are questions such as: What is causing the Universe to blow itself apart? What could be powering the luminous gamma-ray bursters? Where is all the matter in the Universe? Do other Earths exist? Is there intelligent life out there? The renowned author explains clearly, without recourse to mathematics, why each question is puzzling and worthy of research. Included in the study of the wide range of sensitive and powerful instruments used by scientists to try and solve these problems are ones which capture electromagnetic radiation and ‘telescopes’ for cosmic rays, neutrinos, gravitational waves, and dark matter. This book discusses twelve areas of active astronomical research, ranging from the nature of dark energy to the existence or otherwise of extraterrestrial civilizations, and devotes one chapter to each topic. Although astronomers tackle each of these questions using information gleaned from all possible wavelengths and sources (and this is emphasized throughout the book), in this work the author dedicates each chapter to a particular observational method. One chapter covers X-ray telescopes for investigating black holes, while another uses infrared telescopes to learn more about planetary information.

A rigorous and scientific analysis of the myriad possibilities of life beyond our planet. ÒAre we alone in the universe?Ó This tantalizing question has captivated humanity over millennia, but seldom has it been approached rigorously. Today the search for signatures of extraterrestrial life and intelligence has become a rapidly advancing scientific endeavor. Missions to Mars, Europa, and Titan seek evidence of life. Laboratory experiments have made great strides in creating synthetic life, deepening our understanding of conditions that give rise to living entities. And on the horizon are sophisticated telescopes to detect and characterize exoplanets most likely to harbor life. Life in the Cosmos offers a thorough overview of the burgeoning field of astrobiology, including the salient methods and paradigms involved in the search for extraterrestrial life and intelligence. Manasvi Lingam and Abraham Loeb tackle three areas of interest in hunting for life Òout thereÓ: first, the pathways by which life originates and evolves; second, planetary and stellar factors that affect the habitability of worlds, with an eye on the biomarkers that may reveal the presence of microbial life; and finally, the detection of technological signals that could be indicative of intelligence. Drawing on empirical data from observations and experiments, as well as the latest theoretical and computational developments, the authors make a compelling scientific case for the search for life beyond what we can currently see. Meticulous and comprehensive, Life in the Cosmos is a master class from top researchers in astrobiology, suggesting that the answer to our age-old question is closer than ever before.

In November 12, 2002, Dr. John Chambers of the NASA Ames Research Center gave a seminar to the Astrobiology Group at the University of Washington. The audience of about 100 listened with rapt attention as Chambers described results from a computer study of how planetary systems form. The goal of his research was to answer a deceptively simple question: How often would newly forming planetary systems produce Earth-like planets, given a star the size of our own sun? By “Earth-like” Chambers meant a rocky planet with water on its surface, orbiting within a star’s “habitable zone. ” This not-too-hot and not-too-cold inner region, relatively close to the star, supports the presence of liquid water on a planet surface for hundreds of million of years—the time-span probably necessary for the evolution of life. To answer the question of just how many Earth-like planets might be spawned in such a planetary system, Chambers had spent thousands of hours running highly sophisticated modeling programs through arrays of powerful computers. The results presented at the meeting were startling. The simulations showed that rocky planets orbiting at the “right” distances from the central star are easily formed, but they can end up with a wide range of water content. Earth seems to be quite a gem—a rocky planet where not only can liquid water exist for long periods of time, but where water can be found as a heathy oceanful—not too little and not too much. Our planet seems to reside in a benign region of the Galaxy, where comet and asteroid bombardment is tolerable and habitable-zone planets can commonly grow to Earth size. Such real estate in our galaxy—perhaps in any galaxy—is prime for life. And rare as well.
