17 Data about the structure of our reality that they forgot to teach us in school

Our Universe is so full of miracles that it would be impossible to collect them in books. And life really doesn’t get tired of presenting us with some surprises every day, even for those with more scientific and world knowledge. For example, have you ever wondered why caterpillars walk one after another in circles, why the skin on scars is smooth, or what is the biggest cat in the world?

O incredible.club loves the charms of this world full of wonders and shares his impressions and latest discoveries with you.

At a depth of 20 meters, the blood appears to be brown in color, and if you go down to between 40 and 50 meters, it turns green! The water column works like a filter: only green and blue rays pass through it. As a result, the red color disappears at a depth of 3 meters.

This fact not only influenced the work of fish bait manufacturers, but also interested scientists, who recently discovered that fish see better than we do underwater and perceive shades of color that we cannot distinguish.

What would come to your mind if you found the skull of a whale in the heart of Africa, almost 800 km from the ocean and 640 meters above sea level?

According to scientists, in the past, there flowed a deep river where an ancient whale accidentally swam and was unable to return. This happened at a time when the Earth was changing its appearance: forests were turning into savannahs, mountains were growing and humans had to come down from the trees. Due to the analysis of these whale remains, it was possible to determine which stage of human evolution occurred approximately 17 million years ago.

This is how a liger is: a cross between a lion and a tigress, today the largest representative of the felines. Ligers hardly have a lion’s mane, but they know how to swim the same way as tigers.

Building an igloo takes approximately one hour and only one person can do it. In order to keep the heat inside and at the same time ventilate such a shelter, the entrance takes place through a corridor built under the snow. As a result, it is necessary, from the outside, to descend below the floor level and only then enter the igloo.

Everest is the highest point on the planet, at 8,848 meters high. But 450 million years ago, that ridge was the ocean floor that started to grow slowly, about 11 centimeters a year. This fact was officially confirmed for the first time in 1924, when geologist Noel Odell found fossils of ancient marine creatures there.

The first to mask the observation posts with the appearance of trees were the French, then the British, and finally the Germans. So that the enemy would not notice changes in the landscape, false trees were installed during the night. Armies studied the real trees and noted the details to faithfully reproduce them in their workshops. The idea worked so well that none of the observation posts were detected by the enemy.

Scars are formed by collagen. They don’t have hair because the follicles grown before don’t restore themselves. Likewise, the sweat glands do not regenerate either. In addition, when exposed to the sun, scars, unlike healthy skin, react to radiation in a different way and swell slightly.

Jellyfish appeared in the world millions of years ago, and the largest that currently exists is the Cyanea capellata, known as the lion’s mane jellyfish, which lives in the northern Atlantic and Pacific oceans. It is officially considered the longest animal on our Planet.

The brain does not feel pain, and operations are often performed without anesthesia so that the person is conscious. If the patient is a musician, the doctor may ask him to play an instrument during the operation. The whole brain is involved in the process of playing music and if a neurosurgeon makes a mistake, the person will stop playing immediately and the doctor will understand, with the help of the patient, what could have happened.

It is known that teflon is the only material that geckos’ feet do not adhere to, although snails easily achieve this feat.

Water is also a problem for geckos: during a rain, the reptiles cannot climb through the glass or stand on branches and leaves. The liquid creates a thin film that prevents your paws from completely sticking to the surface.

There is a type of butterfly, from the family Psychidae, that builds cocoons in the form of houses. For construction, they use natural materials. If a caterpillar finds twigs in pieces, it will make a small wooden hut, carrying it around until it finishes building. Then, the cocoon will shelter the butterfly’s growth which, after mating, will also lay eggs in the house.

Thus, French winemakers save young feet during spring snowfalls. Sometimes fires need to burn day and night. This is not the only solution that may seem “strange” to lay people…

For example, to protect their production from hurricanes and storms, some winemakers use special apps and other mechanisms that warn them of bad weather. And then, with the help of cannons, they start shooting clouds to avoid the formation of storms.

These insects sleep about 6 hours a day. But when there is a lot of work and they are expending more energy, they allow themselves to “sleep on duty” to continue working efficiently. Another detail: studies suggest that, in the same way that we humans, bees can dream, thus fixing the acquired knowledge.

A curious feature of the Russian spacesuit is that it is possible to put it on without assistance. It is placed on the ground and then the astronaut enters, makes some movements with the body and the door of the spacesuit, which is on the back, closes.

Hundreds of caterpillars move in single file to find a suitable place, burrow into the soil and turn into cocoons. They follow each other instinctively, grabbing each other with their fur as they walk. If the caterpillar leading the line accidentally hits the tail of the last one, they will all get confused and start walking in circles. If you don’t break the cycle, they will march for several days until complete exhaustion and death.

There is still no definitive answer to the question of how certain dinosaurs managed to grow to gigantic proportions, because gravity, which attracts everything, does not contribute to this happening. Therefore, the giant feet of a dinosaur found in 1989 and reaching around 20 meters in height, still intrigues scientists.

The beam of light can create an unusual illusion: it looks like the ruler is moving very slowly. And vice versa: in the dark, time seems to move faster.
