Half the world's population speaks a language that has evolved from a single, prehistoric mother tongue. First spoken in Stone Age times, on the steppes of central Eurasia 6,500 years ago, this mother tongue spread from the shores of the Black Sea across almost all of Europe and much of Asia. It is the genetic basis of everything we speak and write today-the DNA of language.
In this thrilling journey into the mysteries of our cosmos, best-selling author Michio Kaku takes us on a dizzying ride to explore black holes and time machines, multidimensional space, and most tantalizing of all, the possibility that parallel universes may exist alongside our own. Kaku skillfully guides us through the latest innovations in string theory and its latest iteration, M-theory, which posits that our universe may be just one in an endless multiverse, a singular bubble floating in a sea of infinite bubble universes. If M-theory is proven correct, we may perhaps finally find an answer to the question, "What happened before the big bang?"
