After reading this, you realize the name should be "The Road to Realities" (plural). Not only does Penrose demonstrate the relativity of all things, but also the creation aspect inherent in choosing from an infinite number of possibilities on an infinite number of abstraction layers, each with a potential of spawning infinitely more if pursued. In the end, Penrose shows us how both, he created Spinors, and the universe as he knows it could not exist without them. Thus, he created the foundation of the universe? If there were only one reality, the answer would have to be yes.
