Optical illusion: researchers' view of the expanding black hole image
Researchers now believe that visuals trick the brain into believing the viewer is entering a darker place, such as a cave or tunnel. On a white background dotted with smaller black dots is a huge black dot surrounded by a dark halo.
So when a person looks at the image for a few seconds, the dark elliptical section appears to extend outwards, which is why the design is known as an "expanding hole". Scientists found that in a study of 50 people, 86% of participants who looked at the optical illusion saw the growing darkness.
How does the optical illusion of the image work?
The illusion, according to the researchers, is based on how the brain perceives changes in light levels. Therefore, the spreading hole is a highly dynamic illusion. This happens because, when the brain detects a possible change in light intensity, such as entering a tunnel, the pupils contract or dilate to prepare the brain for the change in light ratio offered.
Therefore, what made this image so successful is because it manages to trick the brain, making it make people's pupils dilate, as if they were going from a brighter place to a brighter one. dark. In this way, the researchers also found that those who were able to perceive more marked expansion of the “dark hole” had greater dilation than those who did not feel this It is made.
