Mark Hogarth

Mark Hogarth is a Tutor and Director of Studies (DoS) in Philosophy at Lucy Cavendish College, University of Cambridge. His academic work bridges the philosophy of physics and mathematics, focusing on relativity theory, Gödel’s incompleteness theorems, and computability theory.

His research explores the intersection of spacetime geometry and computational theory, particularly through Malament-Hogarth spacetimes, which enable non-Turing computable tasks by leveraging infinite proper time paths within finite observer time. This work has implications for hypercomputation, supertasks, and the limits of algorithmic decidability in relativistic contexts.

His publications, including studies on black hole inner horizons, mass inflation, and spacetime predictability, highlight his contributions to understanding acausalities, Cauchy horizons, and the deterministic boundaries of general relativity. Key themes include the philosophical consequences of infinite blueshifting and the theoretical role of Turing machines in relativistic frameworks.
