Here's why:
* Strong Gravitational Pull: Black holes have incredibly dense mass packed into a tiny space, creating an extremely powerful gravitational pull.
* Nothing Can Escape: The escape velocity (the speed needed to escape a gravitational pull) at the event horizon of a black hole is higher than the speed of light. This means even light, the fastest thing in the universe, cannot escape the pull of a black hole.
