In this same color optical illusion, are squares A and B the same color? Yes, they are! To confirm, look at the next image to see them connected…
This illusion shows that our human perceptions of science can sometimes be unclear or mistaken, even in something as straightforward as judging color.
Similar illusions occur in the sky, like the apparent size of the Moon on the horizon or the shapes of celestial objects. While modern tools like CCDs have made science and astronomy more objective, they haven’t eliminated the possibility of human biases affecting our observations.
