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.

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.

Quanti anni ha la vita? Qual è il destino delle stelle? Se l'atomo è fatto di vuoto, che cosa sostiene il mondo? Perché solo i nostri neuroni, tra quelli di tutte le specie, sono in grado di descrivere i neutrini? Edoardo Boncinelli e Antonio Ereditato ci raccontano l'avventura dell'Universo: dall'esplosione iniziale al costituirsi dell'architettura delle galassie, dal principio dello spaziotempo all'evoluzione dei sapiens e al sorgere della coscienza umana. Tornano a istanti che vanno da 10-30 a 10-20 secondi dopo il Big Bang.

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.

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.

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'.

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.

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.

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.

Through his extensive research into the interconnected wisdom of the ancients, Scranton shows that the forgotten instructional tradition at the source of this knowledge was deliberately encoded to survive for countless generations. By piecing it back together, we can discover the ancient plan for guiding humanity forward toward greater enlightenment.

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.

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.

One of the leading physicists of her generation, Dr. Chanda Prescod-Weinstein is also one of fewer than one hundred Black American women to earn a PhD from a department of physics. Her vision of the cosmos is vibrant, buoyantly nontraditional, and grounded in Black and queer feminist lineages. Dr. Prescod-Weinstein urges us to recognize how science, like most fields, is rife with racism, misogyny, and other forms of oppression. She lays out a bold new approach to science and society, beginning with the belief that we all have a fundamental right to know and love the night sky.

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.

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.

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?

In the Rutherford and Fry's comprehensive guidebook, they tell the complete story of the universe and absolutely everything in it - skipping over some of the boring parts. It's a celebration of the weirdness of the cosmos, the strangeness of humans and the very fact that amid all the mess, we can somehow make sense of life.

A breakout best seller in Italy, now available for American listeners for the first time, Genesis: The Story of How Everything Began is a short, humanistic tour of the origins of the universe, earth, and life - drawing on the latest discoveries in physics to explain the seven most significant moments in the creation of the cosmos.

This Way to the Universe is a celebration of the astounding, ongoing scientific investigations that have revealed the nature of reality at its smallest, at its largest, and at the scale of our daily lives. The enigmas that Professor Michael Dine discusses are like landmarks on a fantastic journey to the edge of the universe. Asked where to find out about the big bang, dark matter, the Higgs boson particle - the long cutting edge of physics right now - Dine had no single book he could recommend. This is his accessible, authoritative, and up-to-date answer.

You’ve got questions: about space, time, gravity, and your odds of meeting your older self inside a wormhole. All the answers you need are right here. As a species, we may not agree on much, but one thing brings us all together: a need to know. We all wonder, and deep down we all have the same big questions. Why can’t I travel back in time? Where did the universe come from? What’s inside a black hole? Can I rearrange the particles in my cat and turn it into a dog?
