COGNITIVE OPTICAL ILLUSIONS

How are these sights even possible?

The neverending climb

For those who find walking up stairs a chore, this image might be your worst nightmare. Where do these stairs stop? This illusion, known as the Penrose stairs, is designed to hold no start or end point. If you were to try and climb these stairs in real life you would be climbing forever and never reach a higher point. When taking in this image, your general knowledge of the way stairs and elevation work tells you that stairs cannot operate like this, in a continuous loop. Paradox illusions are designed to show the impossible. While this illusion proves possible on paper, it will only work in its twodimensional form, with carefully positioned lines to trick the brain.
