Singularities

Do they exist anywhere other than in the center of black holes?

That depends on the definition, either yes or not even in a black
hole.

Since many think "singularities" in the physical sense is just an
artifact of math. i.e. General relativity breaks down at this point
and you don't get a real singularity. This could mean that to an
observer falling into a black hole would only fall for a finite amount
of time, and be crushed to a finite volume. However this volume could
be the order of a Planck length in size and nothing would look
different to an observer on the outside. i.e. You still have an event
horizon at the same place. i.e. it still looks like a "singularity"
from the outside.

I have almost no sci background, so I'll just try to show my confusion.
I believe in the big bang, which some say was caused be the explosion of
a singularity. On a Sci Chan program, somebody said that black holes
have a singularity at the center. How could a singularity in a black
hole exist before space-time? How could the explosion escape the black
hole? Could another universe be produced if a currently existing
singularity exploded? Please put any response in layman's terms.
Thanks.
