Earlier this week, the Frontiers in Human Neuroscience research team recently discovered optical illusion causes the person to feel as though they are falling into Black hole.

According to the study, a still image with a white background, a few black dots, and a large central orb creates an illusory sense of expansion, forcing the brain to make predictions and communicate a new perception of the world to the eye. Although the image is static, it is a large class of optical patterns that radiate conscious dynamic sensations of illusory movement.

To get a feel for it, first enlarge the image below or click here to see the original image. Looking at the center of the photo for a few seconds, most people notice that the center ball expands and feel like they are falling into the hole.

The reaction can happen anywhere, whether it’s lit or not, and doesn’t have to rely on pupil adjustment, the researchers said. Despite everything, there is no exact explanation for the response that causes this type of reaction, however, experts believe that the illusion shows how the human brain compensates for processing time to perceive what is real, what is distorted by illusions and involuntary reflexes. through the retinas.

“Given that the aforementioned type of illusion also implies an illusory change in brightness, as it involves the expansion of darkness, one can investigate the effect of the illusion not only through the observer’s phenomenology, consisting of conscious verbal reports, but also through the examination of an involuntary physiological indicator: the diameter of the pupil of the eye.”shows research.

Asahi Illusion

Another image used in the study used the illusion AsahiAkiyoshi Kitaoka, which makes people confused with the colors of the figure, i.e. creates the illusion of a geometric resemblance to the gradients formed by highlights of strong sunlight when they are partially obscured by plant leaves or cloud formations for example.

In the example below, you can usually see that the white in the middle of the illusion is much brighter than the surrounding white (on top of the black shapes), even though both are actually the same hue and overall brightness. the image is uniform. .

This phenomenon can be explained by the limitation of the diameter of vision, when the pupil reduces the amount of incoming light, not only to optimize vision, but also to protect the retina from excessive exposure to light.
