If you have a question about this talk, please contact bn257. In this talk I will present concrete evidence that the weak cosmic censorship conjecture can be violated in asymptotically flat spacetimes of five dimensions. This evidence was produced by numerically evolving perturbed black rings. I will describe the evolution of perturbed black rings for the whole range of ring thicknesses. For rings of intermediate thickness we discovered a new instability which causes the ring to collapse to a black hole of spherical topology. For very thin rings the Gregory-Laflamme instability becomes dominant and eventually gives the ring a fractal structure of bulges connected by necks which become ever thinner over time. I will argue that this suggests that very thin black rings break and hence violate weak cosmic censorship. This talk is part of the DAMTP Friday GR Seminar series.
