Description
An investigation of an analogous structure to an event horizon in theories which break Lorentz symmetry. Recent work has shown that in simple spacetimes Lorentz violating theories, such as Einstein-Aether or Horava-Lifshitz, singularities lie behind a *universal horizon* . In the limiting case, signals travel along an incompressible aether which results in an infinitely fast speed of propagation. Despite this property, a universal horizon always appears to form around a singularity disconnecting a region of spacetime from the larger universe. This talk will look at how these structures form during the collapse of a massive charged shell.
