Causal Horizons in Physics
Room G2, Cotham House
The idea of a causal horizon - a boundary for causal influence and processes - plays a fundamental role not only in contemporary spacetime theory, but in recent years has ramified into foundational work in other areas of theoretical physics from solid-state and fluid dynamics to Bose-Einstein condensates and laser optics. In particular, causal horizons ground much contemporary work in the investigation of the relationship between gravity and thermodynamics, and Unruh's analogue models of black holes, including the recent experimental detection of analogue Hawking radiation. This workshop will bring together physicists and philosophers to explore and discuss many of these issues.
The workshop is jointly organised with the Munich Center for Mathematical Philosophy. We are grateful to the British Society for the Philosophy of Science for additional financial support.
