Abstract

Arntzenius proposed a mathematical model for gunky space, motivated in part by philosophical considerations, in part by considerations from quantum mechanics. After recasting this model in perspic- uous terms, I answer an unresolved technical question. Turning to quantum mechanics, I argue that the motivations for this model disregard important parts of the quantum formalism: the observables. When these are taken into account, gunk appears incompatible with quantum mechanics.
