Stephen Hawking avrebbe dovuto passare più tempo ad aiutare la scienza medica a risolvere i problemi, compreso il suo, anziché cercare buchi neri nelle profondità della sua "mente brillante", criticando aspramente quella che lo ha creato. Il dramma che lo ha reso disabile avrebbe potuto spingerlo a usare la sua "mente brillante" per aiutare gli altri sulla terra, invece di cercare buchi neri e inseguire l'infinitesimo, lasciando che se ne occupino quelli che non sono in condizioni fisiche come la sua. Avrebbe potuto divertirsi con un telescopio a casa sua, come facevo io quando abitavo a Miami, North Miami Beach, e poi a Oakland Park, mentre lo scorrere del tempo scandiva la mia vita. A quanto ne so, l'orgoglio di essere l'uomo dei buchi neri non lo sta aiutando, perché avrebbe dovuto spiegarci come difenderci da questi mostri anti Dio. Se uno di loro va fuori orbita e ci viene addosso, lui e la sua famiglia diventano cibo per buchi neri, poiché non hanno un Dio che li difende. Questi divoratori della galassia terrorizzano angeli e demoni, e turbano i sogni dei bambini.

Stephen Hawking, the Lucasian Professor of Mathematics at Cambridge University, has made important theoretical contributions to gravitational theory and has played a major role in the development of cosmology and black hole physics. Hawking's early work, partly in collaboration with Roger Penrose, showed the significance of spacetime singularities for the big bang and black holes. His later work has been concerned with a deeper understanding of these two issues. The work required extensive use of the two great intellectual achievements of the first half of the Twentieth Century: general relativity and quantum mechanics; and these are reflected in the reprinted articles. Hawking's key contributions on black hole radiation and the no-boundary condition on the origin of the universe are included. The present compilation of Stephen Hawking's most important work also includes an introduction by him, which guides the reader though the major highlights of the volume. This volume is thus an essential item in any library and will be an important reference source for those interested in theoretical physics and applied mathematics.
Stephen Hawking è la più celebre tra le grandi figure della scienza contemporanea. Con questo saggio - diventato un classico della divulgazione scientifica - ha permesso anche ai non specialisti di accostarsi alle più importanti scoperte della fisica degli astri, rendendole chiare e avvincenti. Come ebbe origine l'universo, e perché? Quando è cominciato il tempo? Avrà mai fine? Il cosmo è destinato a espandersi per sempre, o un giorno comincerà a contrarsi? Nel creato c'è posto per un creatore? Sono quesiti che l'uomo si pone da sempre, e a cui la scienza comincia a dare risposte verificabili. La struttura dello spazio e del tempo, la loro storia e il loro destino, il principio di indeterminazione, le particelle elementari, i buchi neri, l'unificazione della fisica: queste le tappe di un viaggio appassionante verso le frontiere estreme della cosmologia, in un libro che si è imposto come bestseller internazionale.
The legendary physicist explores his favorite subject in a pair of enlightening, accessible, and cleverly illustrated essays for curious readers, originally delivered as BBC lectures. “It is said that fact is sometimes stranger than fiction, and nowhere is that more true than in the case of black holes. Black holes are stranger than anything dreamed up by science-fiction writers, but they are firmly matters of science fact.” For decades, Stephen Hawking has been fascinated by black holes. He believes that if we understood the challenges they pose to the very nature of space and time, we could unlock the secrets of the universe. In these conversational pieces, Hawking’s sense of wonder is infectious as he holds forth on what we know about black holes, what we still don’t know, and theoretical answers to more specific questions, such as: What would happen if you ever got sucked into one? Annotated and with an introduction by BBC News science editor David Shukman, featuring whimsical and illuminating illustrations, Black Holes offers a candid peek into one of the great scientific mysteries of all time. Praise for Stephen Hawking “[Hawking] can explain the complexities of cosmological physics with an engaging combination of clarity and wit. . . . His is a brain of extraordinary power.”—The New York Review of Books “Hawking clearly possesses a natural teacher’s gifts—easy, good-natured humor and an ability to illustrate highly complex propositions with analogies plucked from daily life.”—The New York Times “A high priest of physics, one of a handful of theorists who may be on the verge of reading God’s mind.”—Los Angeles Times
Stephen Hawking's A Brief History of Time has sold over 9 million copies worldwide. Now, in everyday language, Stephen Hawking's Universe reveals step-by-step how we can all share his understanding of the cosmos, and our own place within it. Stargazing has never been the same since cosmologists discovered that galaxies are moving away from each other at an extraordinary speed. It was this understanding of the movement of galaxies that allowed scientists to develop a theory of how the universe was created—the Big Bang theory. Working with this theory, Stephen Hawking and other physicists felt challenged to come up with a scientific picture that would tackle the fundamental question: what is the nature of the universe? Stephen Hawking's Universe charts this work and provides simple explanations for phenomena that arouse our curiosity. This work is a voyage of discovery with an astonishing set of conclusions that will enable us to understand how matter can be produced from nothing at all and will provide us with an explanation for the basis of our existence and that of everything around us.
NEW YORK TIMES BESTSELLER • Thirteen extraordinary essays shed new light on the mystery of the universe—and on one of the most brilliant thinkers of our time. “[Hawking] sprinkles his explanations with a wry sense of humor and a keen awareness that the sciences today delve not only into the far reaches of the cosmos, but into the inner philosophical world as well.”—The New York Times Book Review In his phenomenal bestseller A Brief History of Time, Stephen Hawking literally transformed the way we think about physics, the universe, reality itself. In these thirteen essays and one remarkable extended interview, the man widely regarded as the most brilliant theoretical physicist since Einstein returns to reveal an amazing array of possibilities for understanding our universe. Building on his earlier work, Hawking discusses imaginary time, how black holes can give birth to baby universes, and scientists’ efforts to find a complete unified theory that would predict everything in the universe. With his characteristic mastery of language, his sense of humor and commitment to plain speaking, Stephen Hawking invites us to know him better—and to share his passion for the voyage of intellect and imagination that has opened new ways to understanding the very nature of the cosmos.
Does Creation need a Creator? This book examines the question of the origin of the universe from the viewpoints of both science and religion. It argues that a scientific explanation for the beginning need not destroy belief in God.
