Given the fact that there are perhaps 400 billion stars in our Galaxy alone, and perhaps 400 billion 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. The sheer enormity of the numbers almost demands that we accept the truth of this hypothesis. Why, then, have we encountered no evidence, no messages, no artifacts of these extraterrestrials? In this second, significantly revised and expanded edition of his widely popular book, Webb discusses in detail the (for now!) 75 most cogent and intriguing solutions to Fermi's famous paradox: If the numbers strongly point to the existence of extraterrestrial civilizations, why have we found no evidence of them? Reviews from the first edition: "Amidst the plethora of books that treat the possibility of extraterrestrial intelligence, this one by Webb ... is outstanding. ... Each solution is presented in a very logical, interesting, thorough manner with accompanying explanations and notes that the intelligent layperson can understand. Webb digs into the issues ... by considering a very broad set of in-depth solutions that he addresses through an interesting and challenging mode of presentation that stretches the mind. ... An excellent book for anyone who has ever asked ‘Are we alone?’." (W. E. Howard III, Choice, March, 2003) "Fifty ideas are presented ... that reveal a clearly reasoned examination of what is known as ‘The Fermi Paradox’. ... For anyone who enjoys a good detective story, or using their thinking faculties and stretching the imagination to the limits ... ‘Where is everybody’ will be enormously informative and entertaining. ... Read this book, and whatever your views are about life elsewhere in the Universe, your appreciation for how special life is here on Earth will be enhanced! A worthy addition to any personal library." (Philip Bridle, BBC Radio, March, 2003) Since gaining a BSc in physics from the University of Bristol and a PhD in theoretical physics from the University of Manchester, Stephen Webb has worked in a variety of universities in the UK. He is a regular contributor to the Yearbook of Astronomy series and has published an undergraduate textbook on distance determination in astronomy and cosmology as well as several popular science books. His interest in the Fermi paradox combines lifelong interests in both science and science fiction.

The search for extra-terrestrial intelligence (SETI) has for sixty years attempted to solve Fermi's paradox: if intelligent life is relatively common in the universe, where is everybody? Examining SETI through this lens, this volume summarises current thinking on the prevalence of intelligent life in the universe, and discusses sixty-six distinct solutions to the so-called paradox. It describes the methodology of SETI, and how many disciplines feed into the debate, from physics and biology, to philosophy and anthropology. The presented solutions are organised into three key groups: rare-Earth solutions, suggesting planetary habitability, life and intelligence are uncommon; catastrophist solutions, arguing civilisations do not survive long enough to make contact; and non-empirical solutions, those that take theoretical approaches, such as that our methodology is flawed. This comprehensive introduction to SETI concludes by looking at the future of the field and speculating on humanity's potential fate.

Researchers believe that the universe is vast enough that life has evolved and become technological many times, - yet we have seen no trace of extraterrestrial intelligence. This conundrum, known as the Fermi paradox, is the deepest mystery in the search for extraterrestrial intelligence. Put simply, where is everybody?

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.

The presence and diversity of thousands of exoplanets, some of which may be similar to Earth, confirmed during the last decade, together with the aptitude for life to emerge, survive and adapt even in the most extreme conditions, as well as the existence of billions of galaxies full of stars, lead us to consider statistically very unlikely that our planet is the only one in the universe to host intelligent life.However, there are still no certain indications concerning extraterrestrial civilizations.In this book, the author suggests a possible explanation by adopting an original approach based on evidence and theories which are generally accepted by the scientific community. He does not just identify the technological aspects of the question but examines the power of the universal evolutionary forces acting on living beings and underscores the cultural and sociological processes involved.

After 50 years of SETI, we have zero hard evidence of alien civilizations, "cosmic wanderlust" resulting in Earth visitations, or UFOs being extraterrestrial in nature, despite - or perhaps because of - the expansiveness of the galaxy. Speculate on reasons for, and solutions to, this so-called Fermi Paradox.

This book presents the reader with some of the earliest classic SF short stories – all of them published between 1858 and 1934, featuring both well-known and long-forgotten writers – dealing for the first time with topics to which science had (some) answers only at much later stages. This includes aspects of alien life forms, transmogrification, pandemics, life on Mars, android robots, big data, matter transmission and impact events to name but a few. The short stories are reprinted in full alongside extensive commentaries which also examine some of the latest scientific thinking surrounding the story’s main theme and provide the reader with suggestions for further reading.

Are 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.

The author presents hundred solutions to the Fermi paradox. The universe is very big and very old, why aren't the aliens here already? Why don't we observe activities of extraterrestrial civilizations in the space? For the mega-civilizations, we are like a Monopoly game on the table, next to the sandwiches and the beer: we are totally visible, accessible, manipulable, and contactable. Why don't superior intelligences contact us in an open manner or officially? They have their good reasons for not doing what we expect from them, which the author explains in this book. We are eagerly waiting for a contact with extraterrestrial civilizations. But what would be the result of an alien visit or attack? There is no need for an alien civilization to be evil in order to destroy us or to inhibit our development turning us into agrarian societies. An extraterrestrial contact could destroy us unintentionally in many ways: as the result of technological and biological accidents or mistakes on the part of the crew or the intelligent machines. Alien visitors could fatally contaminate with extraterrestrial microbes all humans accidentally. Fundamental scientific experiments or grand-scale industrial catastrophes of an alien civilization far away from Earth could delete numerous space races, including our own. Existential risks are those that threaten to destroy the whole population of our civilization or severely reduce its capacity, preventing its normal further development. The extraterrestrial civilizations are among the existential risks for humans. Colonization probes of a biological or machine alien civilization could start massively extracting natural resources and building facilities on the Moon and on Mars. The aliens would not attack or threaten us directly, but humanity would lose the Moon and Mars, which we consider as belonging to us, and which are the next vital step for our space programs. We plan to start human space colonization from the Moon and Mars. Not having the Moon and Mars would be like clipping the space wings of humanity. Stephen Hawking stated, "I think the human race has no future if it doesn't go into space. There are too many accidents that can befall life on a single planet." Aliens could deny us a future. Scholars still cannot answer these grand questions: Do we live in a designer Universe? Are we subject to designer evolution? Are we a designer civilization? Who or what is the designer, and what are his plans? The true resolution of the Fermi paradox depends on the proper answer of these questions.

*Includes pictures *Includes a bibliography for further reading "The size and age of the universe incline us to believe that many technologically advanced civilizations must exist. However, this belief seems logically inconsistent with our lack of observational evidence to support it. Either (1) the initial assumption is incorrect and technologically advanced intelligent life is much rarer than we believe, or (2) our current observations are incomplete and we simply have not detected them yet, or (3) our search methodologies are flawed and we are not searching for the correct indicators, or (4) it is the nature of intelligent life to destroy itself." - The Fermi Paradox As technological advances and the creation of flying aircraft became realities, the sighting of UFOs increased, as did the interest in potential contact with aliens. While incidents like the one at Roswell led to conspiracies and a craze among those who insisted the government was hiding proof of extraterrestrials' existence, governments across the world were actually secretly studying UFO sightings by the mid-20th century. Given all of that, it would hardly be groundbreaking for scientists in the 20th century to have a lunchtime discussion in which the search for extraterrestrial life arises, and the question of where it might reside is innocuous enough. However, a furor was created somewhat innocently when physicist Enrico Fermi voiced his "casual lunchtime remark" in the presence of colleagues in 1950. The august company included Edward Teller, a Hungarian physicist, Herbert York, am American nuclear physicist whose lineage included Mohawk heritage, and Emil Konopinski, a nuclear physicist of Polish origin. Fermi himself, an Italian-American born in Rome, was renowned for developing a statistical base for subatomic phenomena, work on nuclear alterations caused by neutrons, and for leading the first controlled chain reaction from nuclear fission. In pursuit of managing the atom, he created the first nuclear reactor. A gifted theoretician, he advanced the field of statistical mechanics, and won the Nobel Prize over a decade before he asked his important question. The four men represented a fair percentage of the research core during the Manhattan Project that developed and produced the atomic bomb. Despite the sophisticated conversation that appears to have followed, Fermi's oft-asked question soon became elevated within the scientific community as the Fermi Paradox. The subsequent musings on our search for extraterrestrial life have grown to such proportions that extensive lists of solutions to the inquiry proliferate with each passing year. Not only is the core of the question bombarded with speculative theory, but the viability of the term paradox is itself called into question. Merriam-Webster characterizes a paradox as "a statement that is seemingly contradictory or opposed to common sense and yet is perhaps true." The definition adds to the same contradictory statement the caveat of appearing to be true at first. By every account of the Fermi conversation, the physicist raised a question as to where extraterrestrial life might be hiding, not a statement as to whether it existed. For a contradictory statement to be true on a first hearing would require a reversal for the case of extraterrestrial search, as it requires a first observable example. It must begin as an untrue statement, or one that is perceived so. Evidence-based science must proceed then, from the most skeptical position to a hopeful reversal. Similarly, the Merriam-Webster paradox requests a premise steeped in a reasonable model. With no external observations accomplished, our own is the only one available. Human physiological, technological, and cultural structure may be a shaky platform on which to rely against the vastness of potential galactic worlds.
