What would it be like to approach black hole? Well, given that not even light can escape them, it’s better not to be able to check it out. However, there optical illusion it mimics in a certain way what the sensation would be like. And this is not the most interesting. Actually, the most curious thing is that not everyone can perceive it. In fact, according to a study just published in Frontiers of human neuroscience, only 80% of people they can see the black hole getting bigger and bigger.

But this was not verified only by the statements of the participants. The authors of the study from University of Oslofound that the pupils of these people dilated when they perceived as an optical illusion black hole engulfed.

In addition, not everyone perceived the same level of expansion, and this too could be seen. watching your students. It is now unclear why the results of the study participants were so different. This is something to be explored in the future. But what have they seen so far?

Optical illusion turning into a black hole

This optical illusion consists of a white background covered in black dots, with a hazy black hole in the center. By fixing your eyes, you can see how this blurred center is getting bigger and bigger, taking over the entire space. At least that’s what happens in most cases.

The authors of this recently published study wanted to see how this optical illusion affects different people, so they put together 50 participants with normal visionwho were asked to evaluate what they saw.

Also tried to change the background color of the black hole or the hole itself

They had to sit 68 centimeters from the screen and look at it for 8 secondstrying not to close your eyes. In the meantime, measurements were taken of their eye movements, as well as unconscious constriction and dilation of the pupils.

The procedure was carried out both with the original optical illusion and with another, in which the background color of the black hole changed. In particular, it has been tested with blue, cyan, green, magenta, red, white or yellow. They also tried to change the black hole’s own color for each of those colors. The first thing that caught the attention of scientists was that when some colors were introduced, the pupils constricted, as if the eyes had adapted to the bright light. But even this varied greatly between people.

very different results

only 80% participants experienced some black hole growth. In addition, this group included those who discovered an optical illusionbut as a much smaller extension than the rest.

Not all participants found the same level of expansion

On the other hand, optical illusion effects were varies greatly depending on the color of the background or black hole that was no longer black. For example, it expanded more with magenta backgrounds compared to blues and reds. On the contrary, for white holes, the maximum narrowing occurred on a blue background compared to blue and yellow.

Effect purple the researchers were very surprised. And the fact is that, according to the study, it is difficult to associate it with the ecology of light, because “color is not part of the visible spectrum.” colors, the fact that you only see 80% is quite curious, it is known that everything happens because the black hole deceives to the brain so that the pupils dilate and let in more light. Are there brains that are harder to fool? This would give rise to a long discussion, but, undoubtedly, the reasons are much more complicated. Let’s see. So now that we know what this optical illusion is made up of, what percentage are you?
