Summary
This quote implies that black holes, which possess immense gravitational forces and a singularity at their core, represent a boundary beyond which our understanding of the universe breaks down, as if it violates the principles of physics. It metaphorically compares the concept of a black hole to the mathematical impossibility of dividing any number by zero. Just as dividing by zero leads to an undefined result, black holes present a mysterious and incomprehensible aspect of the cosmos, as if they challenge our perception of the natural order and reveal the limits of our knowledge.
