Our three dimensions, Part VI

Unfortunately this vision in three dimensions that give us our two eyes, is not always present, depriving us of feeling, of perceiving the distance which are all the things that make up the universe and that are off the ground. We have all seen those beautiful images of the wonders that reign in the cosmos. Beautiful and magnificent colossal nebulae and precooking galaxies. However, there is something that always frustrates me when it comes to looking at these precious things, not being able to perceive the distance to which they are obviously, I do not mean to see them in photos but with telescopes, binoculars or at a glance.

Stars that seem to be near in a kind of heavenly vault that is touching us but that are really unimaginably far away. Would not it be amazing if we could perceive the distance, the depth in the same way we do when we see a building in the distance?

But this does not end here and is that there are more than 3 types of optical illusions, using each of them one of the weak points of our brain.

The one above creates an illusion of movement, this is a static image, Here what happens is simple, there is so much information in that image that your brain can not process it all and interprets it as if there were movement.

Or this one, where you see perfectly horizontal horizontal blue lines. Yes ... they are horizontal, look for a rule.

Do not you believe me?

This happens because the patterns of the image deceive your brain, playing with the shadows so that this one, once again, tries to take information from where there is none and fails miserably in the process.

This other, squares A and B are the same color, seriously, here, your brain is assuming that B is white because it geometrically touches it and that if it is dark it is because of the shadow.

Sounds logical, the brain is not so stupid, but once again ... it is wrong ... Poor how easy it is to deceive him. Venga.

A little more Do you see these blinking black dots? well, they do not exist, it is your brain that, confused by the black squares that surround the dots, assumes that the distant points must also be black. Sometimes what deceives us is perspective.

These three cars are the same size, but your brain that is a smartass, even though you are seeing them the same, does not let you see it and says: "No no, if they are equal it is because the furthest one is bigger, because their logic tells them that the farther an object is, the smaller it should be, but I am seeing them the same, so the furthest one should be bigger than the closest and for this, decides to cheat, very good brain, another failure ..

And come, to top it off, here you have three impossible objects, this one is called Penrose's triangle. But all this can be taken to another level, because until now we have played with static images, which were not for you, it's something else ... In the next publication, we will see the illusions with movement.
