Primordial naked singularities
arxiv(2024)
摘要
Primordial black hole formation has been discussed widely, when density
perturbations in the early universe cause matter to collapse gravitationally,
giving rise to these ultra-compact objects. We propose here that such a
gravitational collapse also gives rise to primordial naked singularities, that
would play an important role in the observable features of the present
universe. We consider two types of collapse scenarios which would give rise to
event-like and object-like visible singularities. We briefly discuss
implications of primordial naked singularities, including those on dark matter,
vis-a-vis primordial black holes.
