When the collapse of massive stars is studied in some detail, it is discovered that visible or naked singularities do occur in gravitational collapse quite naturally once we use physically realistic assumptions. For example, a higher density at the center of the collapsing star, which decreases as we move outwards, gives rise to a naked singularity as the collapse final state. These conclusions and the wide variety of collapse models that have been investigated over the past years, including non-spherical collapse and numerical simulations, are discussed in this chapter. The chapter tries to understand and explores here in particular, why a naked singularity forms at all rather than a black hole, in gravitational collapse of a massive star. The chapter shows how the intricacies of Einstein gravity and various physical factors play a key role here so as to allow the super ultra-dense regions in the universe to become visible.
