Black Hole

Real World Example

Imagine you're trying to retrieve a ball that has rolled into a deep, narrow well, where it seems impossible to reach or pull it back out. This situation is similar to a black hole, where the gravitational pull is so intense that not even light can escape its grasp, much like how your ball is trapped beyond your reach. Just as the well's depth prevents you from retrieving the ball, a black hole's immense gravity prevents anything from escaping its boundary, known as the event horizon—where not even the fastest thing in the universe, light, can find its way back out.
