Abstract
The metaphysical Growing Block Theory seems particularly well-suited to account for some of our fundamental intuitions about time: time has a direction, our present extends to the whole universe, the past is closed while the future is open, and so on. However, according to the traditional way of defining theories of time, the theory of the growing block is not attractive; it is a hybrid between the two dominant theories, eternalism and presentism, whose main flaws it cumulates. In my talk, I shall propose a redefinition of theories of time, based on their geometric properties, which will enable me to present the growing block theory as a genuine alternative to the dominant theories.
