Pay close attention to image. It is very likely that you will see a black hole expanding in the center and taking over the surrounding area with small balls. That's because, according to a new study, nearly 86% of people are able to spot this intriguing hidden illusion, which is new to science.
However, scientists are still confused as to why a small percentage of humans don't experience this illusory effect. Therefore, check out this article for more details on the effects of optical illusion in this image for science.

The image was analyzed in an article published in Frontiers in Human Neuroscience. A few people can't see the optical illusion of the expanding black hole image.. As well as other species of vertebrates or invertebrates, such as octopuses.
Therefore, in order to better understand the reason for this effect, the researchers analyzed how the color of the dots and the hole affects the intensity of the illusion. In this sense, other colors besides black were tested in the same image, such as blue, green, magenta, white, red, cyan and yellow.
To start, the researchers showed 50 participants with normal vision various visual variations and asked them to rate how strongly they saw the object. It is made. As people looked at the drawing, their eye movements were monitored, including pupil constriction and pupil dilation.
For comparison, another group saw the image in a “shuffled” way, with the same amount of light and color, but no pattern. When the hole was black, the illusion seemed to be more effective, although 14% of participants didn't notice. If the object was colored, the percentage of those who did not experience the illusory effect increased to 20%.
Drawings with dark tones caused significant pupil dilation, while colored drawings caused contrast in this area of the eye. The scientists concluded that the pupillary reaction is not a mechanism independent of any stimulus. in addition to the amount of genuine light that stimulates a specific photoreceptor, according to the new study. Rather, the eye adjusts to perception and even imagined light rather than simply physical energy.
