What actually is Singularity?

A singularity is a place where gravity is so intense that spacetime itself breaks down catastrophically.

It's like a single point with no dimensions.

A singularity is an Infinitely small point with infinite gravity and infinite density. 

Singularity is predicted in Einstein's Theory of General Relativity, but here's the thing...

Infinities never exist in the real world. In the real universe, no black holes contain singularities. 

In general, singularities are the nonphysical mathematical result of a flawed physical theory.

When scientists talk about the black hole singularities, they are talking about the errors... 

...the errors that appear in current theories and not about objects that actually exist. 

So singularities are just a way to describe that we need a better theory to explain Black holes!
