The featured image you are looking at now may be one of the most important optical illusions recently created by scientists. We promise you that it is not a moving GIF and just a regular static drawing, like one you might draw on a piece of paper.
It is called the “expanding hole” optical illusion. It works on about 86% of people. The illusion is so good at fooling your brain that it actually causes your pupils to open up (dilate) as if you were in a dark room.
When looking at the illusion, did you see the central black hole expanding and feel like you are going through a tunnel? Does it feel like you are in a darkened room? Vote and comment below.
