This book by the renowned physicist and science aficionado Dr Michio Kaku is a anthology of all that is latest and greatest in science right now. He explores the future of humanity in the decades and centuries to come, He explains how the current technology will evolve and how that evolution will transform our species from a single planetary civilization to a multi planetary one and then onto being a true galactic civilization; living and thriving among the stars.
His book starts with the revival of space race in modern times, The race to colonize mars and how far humanity is from achieving that objective. He proceeds to explain in scientific terms where humanity is as a civilization and what it should become to avoid the fate of the dinosaurs; an insurance policy of sorts. From there on he moves deeper into the physics of inter planetary travel; slowly increasing the complexity of topics being tackled. He proceeds to the colonization of our solar system and later to the star systems nearby; going over the progression of humanity in great detail.
Eventually reaching the realm of the abstract and science fiction. He starts speaking about the Unified field theory aka the The theory of everything, Time travel, wormholes, structure and existence of multiverses and so on.
To a nerd, this books offers little; at-most it is a reminder of that is great and wonderful in the world. Who the book really serves is the uninitiated, the many sophomore dork who can gain insight and be inspired by the world carefully laid out by Michio Kaku. This book like its author is a great advert for the future of humanity.
