Science fiction has imagined some pretty wild ideas about how the universe could work - from hidden extra dimensions in Interstellar to life as a mental projection in The Matrix. But these imaginings seem downright tame compared to the mind-bending science now coming out of physics and astronomy, and in this audiobook, we look at the strange and fascinating discoveries shaping (and reshaping) the field today.

With impressive examples von Däniken illustrates some of the numerous cities that were dug underground as safe harbors from the destructive boulders. Miles and miles of underground passageways have been discovered around the world as they made space for villages and entire cities. To end the book, von Däniken presents his newest discoveries of an event: In 2017, the author was informed that strange mummified creatures were found near the Peruvian village of Nazca. One of the mummies, apparently several thousand years ago, had been implanted with a metal plate under the skin.

In 1974 a message was beamed towards the stars by the giant Arecibo telescope in Puerto Rico, a brief blast of radio waves designed to alert extraterrestrial civilizations to our existence. Of course, we don't know if such civilizations really exist. But for the past six decades a small cadre of researchers have been on a quest to find out, as part of SETI, the search for extraterrestrial intelligence.

Written in simple and accessible language, this nontechnical introduction to cosmology, or the creation and development of the universe, explains the discipline, covers its history, details the latest developments, and explains what is known, what is believed, and what is purely speculative. In addition, the author discusses the development of the Big Bang theory, and more speculative modern issues like quantum cosmology, superstrings, and dark matter.

Stephen Hawking’s worldwide best seller A Brief History of Time remains a landmark volume in scientific writing. But for those who have asked for a more accessible formulation of its key concepts - the nature of space and time, the role of God in creation, and the history and future of the universe - A Briefer History of Time is Professor Hawking’s response.

In this uniquely American memoir, Homer "Sonny" Hickam beautifully captures a moment when a dying town, a divided family, and a band of teenage dreamers dared to set their sights on the stars. Looking back after a distinguished NASA career that fulfilled his boyhood ambition, Hickam shares the story of his youth, taking listeners into the life of the little mining town and the boys who came to embody both its tensions and its dreams.

The solar system most of us grew up with included nine planets, with Mercury closest to the sun and Pluto at the outer edge. Then, in 2005, astronomer Mike Brown made the discovery of a lifetime: a tenth planet, Eris, slightly bigger than Pluto. But instead of its resulting in one more planet being added to our solar system, Brown’s find ignited a firestorm of controversy that riled the usually sedate world of astronomy and launched him into the public eye.

In 1977, two spacecraft were launched from Earth to explore the outer Solar System, and incredibly, the now-ancient technology from the 1970s is still working, sending daily reports back to the planet that sent the two robotic envoys on their way, over 40 years ago. Voyager 1 and 2 have done far more than accomplish their original missions. In fact, they are now exploring interstellar space, far beyond the outer planets, in the cold wasteland between the stars.

Space and time form the very fabric of the cosmos. Yet they remain among the most mysterious of concepts. Is space an entity? Why does time have a direction? Could the universe exist without space and time? Can we travel to the past?

How can we make intelligent decisions about our increasingly technology-driven lives if we don’t understand the difference between the myths of pseudoscience and the testable hypotheses of science? Pulitzer Prize-winning author and distinguished astronomer Carl Sagan argues that scientific thinking is critical not only to the pursuit of truth but to the very well-being of our democratic institutions.

Astronomer Florian Freistetter has chosen 100 stars that have almost nothing in common. Some are bright and famous, some shine so feebly you need a huge telescope. There are big stars, small stars, nearby stars and faraway stars. Some died a while ago, others have not even yet come into being. Collectively they tell the story of the whole world, according to Freistetter. There is Algol, for example, the Demon Star, whose strange behaviour has long caused people sleepless nights.

Audie Award, History/Biography, 2016. On the night of July 20, 1969, our world changed forever when Neil Armstrong and Buzz Aldrin walked on the moon. Based on in-depth interviews with 23 of the 24 moon voyagers, as well as those who struggled to get the program moving, A Man on the Moon conveys every aspect of the Apollo missions with breathtaking immediacy and stunning detail.

Best-selling author Simon Winchester writes a magnificent history of the pioneering engineers who developed precision machinery to allow us to see as far as the moon and as close as the Higgs boson. Precision is the key to everything. It is an integral, unchallenged and essential component of our modern social, mercantile, scientific, mechanical and intellectual landscapes. The items we value in our daily lives - a camera, a phone, a computer, a bicycle, a car, a dishwasher perhaps - all sport components that fit together with precision and operate with near perfection....

Historian William Sheehan and astronomer and planetary scientist Jim Bell combine their talents to tell a unique story of what we've learned by studying Mars through evolving technologies. What the eye sees as a mysterious red dot wandering through the sky becomes a blurry mirage of apparent seas, continents, and canals as viewed through Earth-based telescopes.

This is a fascinating introduction to the history of Western astronomy, from prehistoric times to the origins of astrophysics in the mid-19th century. Historical records are first found in Babylon and Egypt, and after two millennia the arithmetical astronomy of the Babylonians merged with the Greek geometrical approach to culminate in the Almagest of Ptolemy. This legacy was transmitted to the Latin West via Islam and led to Copernicus's claim that the Earth is in motion.

Astrobiology is an exciting new subject, and one, arguably, more interdisciplinary than any other. Astrobiologists seek to understand the origin and evolution of life on Earth in order to illuminate and guide the search for life on other planets. In this Very Short Introduction, David C. Catling introduces the subject through our understanding of the factors that allowed life to arise and persist on our own planet, and for the signs we are looking for in the search for extraterrestrial life.

In this illuminating audiobook, Tyson and coauthor James Trefil, a renowned physicist and science popularizer, take on the big questions that humanity has been posing for millennia - How did life begin? What is our place in the universe? Are we alone? - and provide answers based on the most current data, observations, and theories.

All the matter and light we can see in the universe makes up a trivial five per cent of everything. The rest is hidden. This could be the biggest puzzle that science has ever faced. Since the 1970s, astronomers have been aware that galaxies have far too little matter in them to account for the way they spin around: they should fly apart, but something concealed holds them together. That ’something' is dark matter - invisible material in five times the quantity of the familiar stuff of stars and planets.

El relato del conocimiento del universo inabarcable, desde la mirada al cielo con el ojo desnudo hasta las sondas enviadas a años luz de la Tierra: una historia que tiene más de 3.600 años de antigüedad.La tarea de resumir más de tres milenios de investigaciones sobre el cielo parece imposible, más difícil aún parece presentarla de modo que pueda ser conocido por cualquier tipo de oyente, independientemente del conocimiento del mismo.
