What is a Black Hole?

Core Definition: A black hole is a region of space with an extraordinarily powerful gravitational field created when massive amounts of matter are packed into a tiny volume.The "Divide-by-Zero" Error: In simple terms, a black hole represents a point where our current understanding of physics breaks down—a mathematical singularity where space-time equations result in an undefined state.Event Horizon: The absolute point of no return. Gravity is so strong within the event horizon that not even light can escape, causing its trajectory to loop back inward.
