Bradley Monton (2006) has argued that a specific version of canonical quantum gravity – that with a so-called constant mean extrinsic curvature [CMC] (or fixed) foliation – has the necessary resources to render presentism (the view that all and only presently existing things exist) a live possibility (see the section on Presentism, Eternalism, and The Growing Universe Theory in the entry on time for more on presentism). The reason is that with such a fixed foliation one has at one’s disposal s
