Bøger af Avi Loeb

Avi Loeb, ledende astrofysiker ved Harvard University, fremlægger sin kontroversielle teori om, at vores solsystem for nylig blev besøgt af avanceret og fremmed teknologi fra en fjern stjerne. I slutningen af 2017 fik nogle forskere på et observatorium i Hawaii øje på et objekt, der kom flyvende gennem vores indre solsystem og bevægede sig så hurtigt, at det nødvendigvis måtte stamme fra en anden stjerne. Avi Loeb påviste, at det ikke kunne være en asteroide. Objektet bevægede sig ganske enkelt for hurtigt og langs en underlig bane – og det forsvandt sporløst. Bogen er en tankevækkende rejse til videnskabens og den menneskelige forestillingsevnes yderste grænser.

'The 'Enfant terrible' of astrophysics . . . Loeb has a joy in conjecture and an omnivorous spirit of inquiry that are more reminiscent of 20th-century thinkers such as Freeman Dyson or Carl Sagan than most of his peers' The TimesCould we build space craft that could travel to distant stars? Could we augment human biology for spaceflight? Could the search for extraterrestrials be brought into the mainstream of scientific research?Avi Loeb tells us that in each case, the real question is not could we, but will we choose to? With an approach that is firmly grounded in cutting-edge science, he explores the potential for non-rocket space launch, deep space probes, and the technological preservation of human civilisation. He examines the evidence for UFOs and UAPs, and argues that the search for further evidence, using existing scientific technologies, is long overdue.Urgent and important, Noah's Spaceship is a mission statement and a blueprint for the future of humanity. Loeb explains why becoming interstellar is imperative for our civilization to survive - and how we can accomplish it.'One of the more imaginative and articulate scientists around' New York Times

"The world's leading alien hunter" -- New York Times MagazineFrom acclaimed Harvard astrophysicist and bestselling author of Extraterrestrial comes a mind-expanding new book explaining why becoming an interstellar species is imperative for humanity's survival and detailing a game plan for how we can settle among the stars.In the New York Times bestseller Extraterrestrial, Avi Loeb, the longest serving Chair of Harvard's Astronomy Department, presented a theory that shook the scientific community: our solar system, Loeb claimed, had likely been visited by a piece of advanced alien technology from a distant star. This provocative and persuasive argument opened millions of minds internationally to the vast possibilities of our universe and the existence of intelligent life beyond Earth. But a crucial question remained: now that we are aware of the existence of extraterrestrial life, what do we do next? How do we prepare ourselves for interaction with interstellar extraterrestrial civilization? How can our species become interstellar?Now Loeb tackles these questions in a revelatory, powerful call to arms that reimagines the idea of contact with extraterrestrial civilizations. Dismantling our science-fiction fueled visions of a human and alien life encounter, Interstellar provides a realistic and practical blueprint for how such an interaction might actually occur, resetting our cultural understanding and expectation of what it means to identify an extraterrestrial object. From awe-inspiring searches for extraterrestrial technology, to the heated debate of the existence of Unidentified Aerial Phenomena, Loeb provides a thrilling, front-row view of the monumental progress in science and technology currently preparing us for contact. He also lays out the profound implications of becoming--or not becoming--interstellar; in an urgent, eloquent appeal for more proactive engagement with the world beyond ours, he powerfully contends why we must seek out other life forms, and in the process, choose who and what we are within the universe.Combining cutting edge science, physics, and philosophy, Interstellar revolutionizes the approach to our search for extraterrestrial life and our preparation for its discovery. In this eye-opening, necessary look at our future, Avi Loeb artfully and expertly raises some of the most important questions facing us as humans, and proves, once again, that scientific curiosity is the key to our survival.
