Giovanni F. Bignami – författare

In this book, Giovanni Bignami, the outstanding Italian scientist and astronomer, takes the reader on a journey through the “seven spheres”, from our own planet to neighboring stars. The author offers a gripping account of the evolution of Homo Sapiens to the stage where our species is developing capabilities, in the form of new energy propulsion systems, that will enable us to conquer space. The reader will learn how we first expanded our activities to reach beyond our planet, to the Moon, and how nuclear energy, nuclear fusion, and matter–antimatter annihilation will enable us to extend our exploration. After Mars and Jupiter we shall finally reach the nearest stars, which we now know are surrounded by numerous planets, some of which are bound to be habitable. The book includes enticing descriptions of such newly discovered planets and also brings alive key historical characters in our story, such as Jules Verne and Werner von Braun.

For many thousands of years, human beings have been asking themselves whether they are more frightened of being alone in the universe or of the thought that there is someone else out there. Over the past few decades, however, we have moved from imagination to action, exploring the cosmos using new techniques, often with surprising results. Numerous fascinating but little known facts have emerged – for example, that every year many rocks from Mars fall on the Earth, that one of our amino acids has been found in the coma of a comet, and that some of the known thousands of extrasolar planets are similar to our own. There are further exciting and important discoveries around the corner that will cast more light on the great enigma of how life started on Earth. In this intriguing book, one of the World’s leading researchers in astrophysics and space science examines fundamental questions concerning life on Earth and the rest of the cosmos in an accessible and stimulating way.

This book develops a credible scenario for interstellar exploration and colonization. In so doing, it examines: • the present situation and prospects for interstellar exploration technologies; • where to go: the search for habitable planets; • the motivations for space travel and colonization; • the financial mechanisms required to fund such enterprises. The final section of the book analyzes the uncertainties surrounding the presented scenario. The purpose of building a scenario is not only to pinpoint future events but also to highlight the uncertainties that may propel the future in different directions. Interstellar travel and colonization requires a civilization in which human beings see themselves as inhabitants of a single planet and in which global governance of these processes is conducted on a cooperative basis. The key question is, then, whether our present civilization is ready for such an endeavor, reflecting the fact that the critical uncertainties arepolitical and cultural in nature. It is written in such a way as to allow the non-professional reader to become part of the debate on the future of space programs.

This is not science fiction. It’s a voyage on the arrow of time to the coming fifty years. The legendary palindromic character Mr. Qfwfq from Italo Calvino’s collection of short stories, The Cosmicomics, will go with us – he who knows all the answers but will give out no hints. He will help us to discover the innovations that will have changed our lives by 2062, when, riding astride Halley’s Comet, our omniscient extraterrestrial will return to visit us.In this book, we shall learn how astronomers will devote themselves to the study of the mysterious force of dark energy, which makes up some three-quarters of the Universe. We shall also delve deeply into the study of our Earth, to exploit the immense thermal energy that lies beneath our feet. We shall solve another enigma in today’s science: the origin of life. We shall come to understand how to develop direct contacts between our brains and the rest of the world. We shall learn about the future of genetics, the reason for the longevity of Methuselah flies and the quest for prime numbers. These are only some of the exciting and important discoveries to be revealed in this intriguing book, which is designed for a broader public and not only for science fiction devotees.
