This image is a famous optical illusion known as the “impossible staircase” or “Schröder’s stairs.” It plays with perspective, making it appear as though the staircase can be seen in two different orientations simultaneously—either as steps going up or down, depending on how the viewer interprets the shading and angles. This illusion is a classic example of ambiguous figures, where the brain alternates between two equally valid but contradictory perceptions. Follow @spacecameocommunity for more.

La escalera de Penrose es una ilusión óptica imposible creada por Lionel y Roger Penrose en 1958.
