Years ago, cosmologist Stephon Alexander received life-changing advice: to discover real physics, he needed to stop memorizing and start taking risks. In Fear of a Black Universe, Alexander shows that great physics requires us to think outside the mainstream - to improvise and rely on intuition. His approach leads him to three principles that shape all theories of the universe: the principle of invariance, the quantum principle, and the principle of emergence. Alexander uses them to explore some of physics' greatest mysteries.

What does it mean to be human, to live on planet Earth, in the universe as it is now understood? Best-selling author and mathematical cosmologist Brain Swimme takes us on a journey through the cosmos in search of the “new story” that is developing in answer to this age-old question.

A respected physics professor and author breaks down the great debate over the big bang and the continuing quest to understand the fate of the universe.

When Stephen Hawking died, he was widely recognized as the world's best physicist, and even its smartest person. He was neither. In Hawking Hawking, science journalist Charles Seife explores how Stephen Hawking came to be thought of as humanity's greatest genius. Hawking spent his career grappling with deep questions in physics, but his renown didn't rest on his science. He was a master of self-promotion, hosting parties for time travelers, declaring victory over problems he had not solved, and wooing billionaires.

Harry Cliff - a University of Cambridge particle physicist and researcher on the Large Hadron Collider - sets out in pursuit of answers. He ventures to the largest underground research facility in the world, deep beneath Italy's Gran Sasso mountains, where scientists gaze into the heart of the Sun using the most elusive of particles, the ghostly neutrino. He visits CERN in Switzerland to explore the "Antimatter Factory," where the stuff of science fiction is manufactured daily (and we're close to knowing whether it falls up).

Physicist Harry Cliff ventures out in search of the ultimate apple pie recipe, tracing the ingredients of our universe through the hearts of dying stars and back in time to a tiny fraction of a second after our universe began. Along the way, he confronts some really big questions: what is matter really made of? How does the stuff around us escape annihilation in the fearsome heat of the Big Bang? And will we ever be able to understand the very first moments of our universe?

Scientists have been searching for aliens in our solar system and beyond, but have not yet found evidence that life exists beyond Earth. SETI, the Search for Extraterrestrial Intelligence, has been scanning the stars for alien radio beacons for 50 years. Radio and TV broadcasts have been leaking from Earth’s atmosphere for over a century, and these traveling time capsules could eventually reach a broader audience than ever imagined. Neil and Lynne review the methods used to locate aliens and discuss what to do if you’re ever abducted.

Un cibo non troppo caldo e non troppo freddo, un letto non troppo morbido e non troppo duro: ecco cosa vuole la giovane protagonista della fiaba "Riccioli d'oro e i tre orsi", qualcosa di "proprio giusto". Sembra bizzarro, eppure l'astrobiologia usa lo stesso criterio nella ricerca di possibili forme di vita nello spazio. Tanto che si chiama "Fascia Riccioli d'oro" la zona abitabile di un sistema stellare, lo spazio in cui si trovano i pianeti che possiedono le caratteristiche necessarie allo sviluppo della vita: presenza di acqua, temperature non eccessivamente calde o fredde.

In The Earth's Imagination, cosmologist Brian Thomas Swimme places the human psyche within the 15 billion-year cosmic process in order to highlight the directions in which human consciousness is evolving today and into the future. With a remarkable ability to make contemporary scientific findings accessible and engaging, Dr. Brian Thomas Swimme relates the history of the universe to the modern human.

Once dismissed as a mathematical curiosity, black holes are so strange they almost defy belief. Since their existence was confirmed, research into the nature of black holes has opened up new vistas in physics. In this audiobook, we examine some of the most fascinating discoveries about black hole formation and behavior, the new and evolving research in gravitational wave astronomy, theoretical possibilities such as wormholes, and much more.

One of the most peculiar and possibly unique features of humans is the vast amount of information we carry outside our biological selves. But in our rush to build the infrastructure for the 20 quintillion bits we create every day, we’ve failed to ask exactly why we’re expending ever-increasing amounts of energy, resources, and human effort to maintain all this data. Drawing on deep ideas and frontier thinking in evolutionary biology, computer science, information theory, and astrobiology, Caleb Scharf argues that information is, in a very real sense, alive - an aggregate lifeform.

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.

This audiobook begins with the question "Who am I?" and immediately sets off in an astonishingly original direction. Why didn't anyone before Harding think of responding to this question like this? It's so obvious, once you see it. Harding presents a new vision of our place in the universe that uses the scientific method of looking to see what is true. It turns out that the truth about ourselves is not only true but also very good, and breathtakingly beautiful. We live in a sacred, many-layered, living universe - or rather it lives in us.

Shaun Usher brings together fascinating correspondence about the universe beyond our planet, containing hopeful thoughts about the future of space travel, awestruck messages penned about the worlds beyond our own and celebrations of the human ingenuity that has facilitated our understanding of the cosmos.

L'universo racchiude numerosi segreti e potrebbe perfino nascondere dimensioni inimmaginabili: universi paralleli, geometrie curve e inghiottitoi tridimensionali sono alcuni degli straordinari concetti che di recente sono divenuti protagonisti della ricerca scientifica. Oggi, delle leggi del cosmo capiamo molto più di qualche anno fa, eppure abbiamo molte meno certezze sulla sua vera natura. Nel suo percorso di ricerca nel campo della cosmologia e della fisica, Lisa Randall ha dovuto abbattere alcuni paletti della scienza ufficiale.

It has been argued that science fiction (SF) gives a kind of weather forecast - not the telling of a fortune but rather the rough feeling of what the future might be like. The intention in this audiobook is to consider some of these bygone forecasts made by SF and to use this as a prism through which to view current developments in science and technology.

"Hace muchos años -1976- estuve en Tucson, Arizona, y en el planetario de la ciudad había un ciclo de charlas de divulgación. Una de ellas me llamó poderosamente la atención. La ofrecía el astrónomo de la Universidad de Arizona, Nick Woolf, y se titulaba "The Universe: I can Feel it in my Bones". El título era tan provocativo que me inspiró para una charla pública que, ya de vuelta en Chile, he dictado durante años: "Somos polvo de estrellas". A miles de jóvenes y no tan jóvenes les he contado lo que yo considero una de las más grandes historias de la astronomía.

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?

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.

Our scientists might be armed with giant telescopes and powerful particle accelerators, yet their goal is the same one that has impelled the human imagination since ancient times: to show us our place in the universe. The result of their collective efforts is a complex story. At times it stretches the imagination just as much as the old creation myths. But its building blocks give us the power to work marvels our predecessors could scarcely comprehend. In Genesis, Guido Tonelli sets out 'to do justice to the great origin story that modern science gives us'.
