Singularity

Singularity is the state, fact, quality, or condition of being singular. In physics and mathematics it is a point at which a function takes an infinite or undefinable value, especially in space-time when matter is infinitely dense. In theory this may take place at the center of a black hole.

Supposedly we cannot exist within regions of space of infinite density and singularity did not occur at a single point because an infinite density cannot be reached throughout the entire universe at the same time. There are those who believe the new wavecentric model of the universe excludes singularity because it never existed at the beginning of the universe. But that would assume the universe only exists in the observable space and time. It is space and time that is essential for the creation of the observable universe and may not existed in a "realm" or dimension where singularity may exist.

Christians believe in a singular personal God who is loving creator that is knowable. It may not be entirely knowable to finite creatures but knowable enough to tap into that realm of singularity in which it exists.
