At the most fundamental level that we currently know of, therefore, there is little that resembles time as we experience it. There is no special variable “time,” there is no difference between past and future, there is no spacetime (Part Two). We still know how to write equations that describe the world. In those equations, the variables evolve with respect to each other (chapter 8). It is not a “static” world, or a “block universe” where all change is illusory (chapter 7): on the contrary, ours is a world of events rather than of things (chapter 6).
