Title |
Black Hole Information Loss - What's the problem? | |||||
| Co-authors | Lee Smolin | |||||||
|
Abstract |
In this talk I will classify possible solutions to the black hole information loss problem in form of causal diagrams. I will argue that, short of giving up unitarity, the most conservative solution is the removal of the singulatity. I will summarize reasons why singularity avoidance has not generally been considered sufficient as a solution, and why these reasons are not conclusive. Based on this, I will discuss where more research is needed to understand the mechanism of information recovery. This talk is based on arXiv:0901.3156, Phys. Rev.D81:064009 (2010). |

Title |
How to beat a cosmic speeding ticket | |||||
| Co-authors | ||||||||
|
Abstract |
In this talk I will argue it is possible that, within a theory of quantum gravity, special relativity is modified so as to allow for superluminal information exchange. This is possible without inducing higher order operators coupling to a preferred frame, and without causing problems with locality or causality. |
