Critical acclaim for Michio Kaku’s previous book, Hyperspace:

"Among the best of its genre to appear in recent years…What a wonderful adventure it is, trying to think the unthinkable!"
–The New York Times Book Review

"A roller coaster of an intellectual ride through the extraordinary world of black holes, wormholes, parallel universes, higher dimensions and time travel."
–Philadelphia Inquirer

"Mesmerizing…the reader exits dizzy, elated and looking at the world in a
literally revolutionary way."
–Washington Post
