Detailed explanation-1: -The universal origin story known as the Big Bang postulates that, 13.7 billion years ago, our universe emerged from a singularity-a point of infinite density and gravity-and that before this event, space and time did not exist (which means the Big Bang took place at no place and no time).
Detailed explanation-2: -What would a singularity look like in the quantum mechanical context? Most likely, it would appear as an extreme concentration of a huge mass (more than a few solar masses for astrophysical black holes) within a tiny volume.
Detailed explanation-3: -The two most important types of space-time singularities are known as Curvature Singularities and Conical Singularities. Singularities can also be divided according to whether they are covered by an event horizon or not.
