The Penrose stairs

The Penrose stairs are an optical illusion featuring a staircase that appears to ascend or descend endlessly in a loop, defying physical laws of geometry and gravity. They create a paradox where each step seems to go up or down forever, but in reality, such a structure cannot exist in three-dimensional space. This illusion challenges our perception of space and reality, illustrating how our visual system can be fooled by clever design and perspective tricks. The Penrose stairs are often used to explore concepts related to impossible objects and the mind’s interpretation of spatial relationships.
