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.

Primordial black hole formation has been a topic of widespread discussion in the scientific community. It involves the gravitational collapse of matter in the early universe, resulting in the creation of ultra-compact objects known as black holes. However, we propose that this collapse also leads to the formation of primordial naked singularities.

These primordial naked singularities have the potential to significantly impact the observable features of the present universe. We have identified two types of collapse scenarios that can give rise to visible singularities. The first scenario involves event-like visible singularities, while the second scenario involves object-like visible singularities.

The implications of primordial naked singularities are far-reaching, particularly with regards to dark matter. The presence of these singularities could have significant consequences on the behavior and distribution of dark matter in the universe.
