Impossible Stairs

The Penrose stairs, also known as the impossible staircase, presents a two-dimensional representation of a staircase that makes four 90-degree turns while ascending or descending, yet forms a continuous loop without interruption. This conceptual impossibility disrupts your perception, creating an optical illusion where it appears as though a person could climb forever and still not reach a higher point. Witnessing the video is the simplest way to grasp how this seemingly paradoxical structure functions.
