Wilson Literary Science Writing Award “Provocative and thrilling ... Loeb asks us to think big and to expect the unexpected.” —Alan Lightman, New York Times bestselling author of Einstein’s Dreams and Searching for Stars on an Island in Maine Harvard’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.

Experts critically examine the belief that other intelligent life exists in our galaxy.

Explores the role of ETs in the military, government, technology, history, and the coming new age • Surveys contact with ETs, abductions, alien technology and exopolitics, genetic tampering by ETs, and the history behind the Nazis and UFOs • Contains interviews with Jesse Marcel, Michael Salla, Paul LaViolette, Robert Bauval, Helen Wambach, and others at the forefront of the ET-derived New Science movement The extraterrestrial presence on Earth is widening and, as we enter the Aquarian Age, will be admitted officially, causing shock and an urgent universal need to understand the social and technological changes derived from our space brothers. A primer for the explosive advances humanity will experience scientifically and spiritually in the coming years, this compendium explores the ET phenomenon and its influence on humanity past and present. The book surveys contact with ETs and abduction accounts, unexplained public and undisclosed military technology from aliens including anti-gravity devices, exopolitics (the influence of ETs in human affairs), the Iraqi Stargate, the Hybrid Project of alien interbreeding by abduction, Nazi ties to UFOS and their secret underground base in Antarctica, government cover-ups of alien interactions including Roswell, and the transformation triggered by the Hale-Bopp comet. Based on interviews with people who are witnessing the coming changes as well as those visionaries who are actually bringing them about--including John Mack, Major Jesse Marcel, Paul LaViolette, Robert Bauval, Michael Salla, and Helen Wambach--this book sketches out a breathtaking vision of the planetary revolution just around the corner.

Are alien civilizations really possible? If extraterrestrials exist, where are they? How likely is it that somewhere in the universe an Earth-like planet supports an advanced culture? Why do so many people claim to have encountered Aliens? In this gripping exploration, scientist Don Lincoln exposes and explains the truths about the belief in and the search for life on other planets. In the first half of Alien Universe, Lincoln looks to Western civilization's collective image of Aliens, showing how our perceptions of extraterrestrials have evolved over time. The roots of this belief can be traced as far back as our earliest recognition of other planets in the universe—the idea of them supporting life was a natural progression of thinking that has fascinated us ever since. Our captivation with Aliens has, however, led to mixed results. The world was fooled in the nineteenth century during the Great Moon Hoax of 1835, and many people misunderstood Orson Welles's 1938 radio broadcast, The War of the Worlds, leading to significant anxiety among some listeners. Our continuing interest in Aliens is reflected in entertainment successes such as E.T., The X-Files, and Star Trek. The second half of the book explores the scientific possibility of whether advanced Alien civilizations do exist. For many years, researchers have sought to answer Enrico Fermi’s great paradox—if there are so many planets in the universe and there is a high probability that many of those can support life, then why have we not actually encountered any Aliens? Lincoln describes how modern science teaches us what is possible and what is not in our search for extraterrestrial civilizations. Whether you are drawn to the psychological belief in Aliens, the history of our interest in life on other planets, or the scientific possibility of Alien existence, Alien Universe is sure to hold you spellbound.

If 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.

This book describes a wide variety of speculations by many authors about the consequences for humanity of coming into contact with extraterrestrial intelligence. The assumptions underlying those speculations are examined, and some conclusions are drawn. The book emphasizes the consequences of contact rather than the search, and takes account of popular views. As necessary background, the book also includes brief summaries of the history of thinking about extraterrestrial intelligence, searches for life and for signals, contrasting paradigms of how contact might take place, and the paradox that those paradigms allegedly create.
