Gravitational Tunneling in Lorentz Violating Gravity
F. Del Porro, M. Herrero-Valea, S. Liberati +1
Black holes in Lorentz violating gravity, such as Einstein--Aether or Horava--Lifshitz Gravity, are drastically different from their general relativistic siblings. Although they al…
Space-like Singularities of General Relativity: A Phantom menace?
Abhay Ashtekar, Adrián del Río, Marc Schneider
The big bang and the Schwarzschild singularities are space-like. They are generally regarded as the "final frontiers" at which space-time ends and general relativity breaks down. W…
Time Orientability and Particle Production from Universal Horizons
Francesco Del Porro, Mario Herrero-Valea, Stefano Liberati +1
We discuss particle production in spacetimes endowed with a universal horizon in Einstein--Aether and Horava gravity. We argue that continuity and differentiability of the lapse fu…
