报告摘要： Gravitational theories with broken Lorentz invariance (LI) have attracted a great deal of interest recently, as they provide a test bed of LI and more importantly offer a mechanism to improve the ultraviolet behavior of the theories, so that they may be renormalizable and unitary. However, in such theories particles can travel with arbitrary speeds, and black holes may not exist at all. In contrast to this intuition, it has been found that an absolute horizon indeed exists, which traps signals even with infinitely large velocities. In this talk, I shall give an updated review of the topic, and pay particular attention on the thermodynamics of such black holes and their formation from gravitational collapse.
