Abstract
Abstract: If the early universe was highly anisotropic, primordial black holes may have formed prolifically (despite previous claims to the contrary) even if the initial density fluctuations were small. However, the holes would initially be endowed with an immense amount of shear, so it is not obvious that they would evolve into the conventional type ofstationary black hole envisaged by the “no hair” theorem. If they do settle down to a stationary state, it may only be on a considerable time scale; and in principle there might exist soliton-type solutions which represent holes with shear which persists indefinitely. Such “shear hell holes,” as we term them, could have even more dramatic properties than the usual stationary holes: in particular, they might be prolific generators of gravitational radiation and they could be associated with interesting quantum effects.
