Is our universe dying? Could there be other universes? In Parallel Worlds, world-renowned physicist and bestselling author Michio Kaku-an author who "has a knack for bringing the most ethereal ideas down to earth" (Wall Street Journal)-takes readers on a fascinating tour of cosmology, M-theory, and its implications for the fate of the universe. In his first book of physics since Hyperspace, Michio Kaku begins by describing the extraordinary advances that have transformed cosmology over the last century, and particularly over the last decade, forcing scientists around the world to rethink our understanding of the birth of the universe, and its ultimate fate. In Dr. Kaku's eyes, we are living in a golden age of physics, as new discoveries from the WMAP and COBE satellites and the Hubble space telescope have given us unprecedented pictures of our universe in its infancy. As astronomers wade through the avalanche of data from the WMAP satellite, a new cosmological picture is emerging. So far, the leading theory about the birth of the universe is the "inflationary universe theory," a major refinement on the big bang theory. In this theory, our universe may be but one in a multiverse, floating like a bubble in an infinite sea of bubble universes, with new universes being created all the time. A parallel universe may well hover a mere millimeter from our own. The very idea of parallel universes and the string theory that can explain their existence was once viewed with suspicion by scientists, seen as the province of mystics, charlatans, and cranks. But today, physicists overwhelmingly support string-theory, and its latest iteration, M-theory, as it is this one theory that, if proven correct, would reconcile the four forces of the universe simply and elegantly, and answer the question "What happened before the big bang?" Already, Kaku explains, the world's foremost physicists and astronomers are searching for ways to test the theory of the multiverse using highly sophisticated wave detectors, gravity lenses, satellites, and telescopes. The implications of M-theory are fascinating and endless. If parallel worlds do exist, Kaku speculates, in time, perhaps a trillion years or more from now, as appears likely, when our universe grows cold and dark in what scientists describe as a big freeze, advanced civilizations may well find a way to escape our universe in a kind of "inter-dimensional lifeboat." An unforgettable journey into black holes and time machines, alternate universes, and multidimensional space, Parallel Worlds gives us a compelling portrait of the revolution sweeping the world of cosmology.… (mais)
Parte bene, ma poi vira verso la fantascienza di bassa lega
La data originale di pubblicazione di questo libro è il 2003: sappiate dunque che non potrete trovare le "ultime notizie" sulla cosmologia, come per esempio la rilevazione di onde gravitazionali. (Non che mi pare ci sia stato molto altro: occhei, il bosone di Higgs, ma Kaku lo dava già praticamente per scontato). Kaku è siouramente innamorato della sua materia, e lo si vede quando racconta le cose. La prima parte del libro è ottima per avere uno sguardo globale sulle varie facce della cosmologia. Poi però nella seconda parte comincia a esagerare con la teoria - anzi LE teorie - delle stringhe, che per fortuna hanno perso l'appeal che avevano al tempo. La terza parte sugli universi paralleli è proprio a livello di romanzetto di fantascienza, e si può tranquillamente saltare. Non aspettatevi insomma troppo.
Qualche caduta nella traduzione di Andrea Migliori, con un "piuttosto" alla milanese e le decades che diventano secoli. ( )
Physics and cosmology sprinkled with some sci-fi discussion. Good stuff. This book is a little dated because it doesn't include the new LHC findings. But it is still mind-bendingly fun to read. ( )
En Universos paralelos, Michio Kaku hace gala de todo su formidable talento didáctico para enfrentarse a una de las mas extrañas y excitantes posibilidades que ha surgido en la física contemporánea: que nuestro universo puede ser uno entre los muchos quizá infinitos que han surgido en el cosmos. Con un uso habilidoso de la analogía y el humor, Kaku introduce pacientemente al lector en todas las variaciones sobre el tema de los universos paralelos procedentes de la física cuántica, la cosmología y la reciente teoría M. Leer este libro conducido por un experto guía es un maravilloso recorrido por un cosmos cuya comprensión nos fuerza a alcanzar los últimos limites de la imaginación.
This was my first time reading a book by Kaku, and it won't be my last! I've been into spaceand phyics since I was 7, and I'v never been able to resist a good book on wormholes! This is fantastic, and anyone could read this book, becuase Kaku explains everything so detailedly! ( )
Ky libër është një guide e shkëlqyer për të kuptuar më mirë kozmosin. Prandaj konsiderohet një udhëtim përmes krijimit, dimensioneve të pafundme dhe të ardhmes së kozmosit. Autori është ndër shkencëtarët më të shquar të kohës tonë, i cili komunikon me lexuesit çështje të dimensioneve të thella përmes një gjuhe të thjeshtë dhe të qartë
