Forever is a day: Supertasks in Pitowsky and Malament-Hogarth spacetimes

Philosophy of Science 60 (1):22-42 (1993)
Abstract
The standard theory of computation excludes computations whose completion requires an infinite number of steps. Malament-Hogarth spacetimes admit observers whose pasts contain entire future-directed, timelike half-curves of infinite proper length. We investigate the physical properties of these spacetimes and ask whether they and other spacetimes allow the observer to know the outcome of a computation with infinitely many steps
