Abstract: I explore a new solution to Sattig’s problem of relativistic change. First, I provide a reassessment of the problem, according to which the numerically same object appears to have something as a part in one frame but not at another (i.e. its “corner slices”). Second, I present a new solution that takes this mereological difference seriously, thus entailing that the relevant ordinary object is frame-bound. Finally, while this solution is naturally coupled with four-dimensionalism, I explore the possibility of coupling it with three-dimensionalism in order to provide an answer to Gilmore’s location question.
