We live in a unique civilization, whose knowledge allows us to control weather conditions, get out into space, grow up children in test tubes, as well as genetically modified crops in the fields. In addition, even the scientists themselves are not ready to answer some of them, despite a number of practical experiments and the most incredible theories.
The simplest questions of our daily lives often do not have clear and intelligible answers. In this case, even an adult can feel like a lot of money, trying to find and interpret them. We present to you the TOP 10 of such banal, but at the same time very complex questions to which world scientists still have not given clear answers, supported by evidence.
10. Why do cats purr
A lot of different articles were written and research was conducted on the origin of the “rumbling apparatus” in cats, but no sensible result was obtained. Fluffy pussies continue to purr in moments when they are comfortable, cozy and pleasant (as other factors confirm). Yes, it is in the process of obtaining pleasure that purr makes these rumbling sounds more often. But scientists are shocked by unexpected observations, because a cat can purr from hunger or fear. And here the theories built over the years immediately collapse, one of which says that supposedly the vibrations of sounds help feline heal tendons and bones.
9. Why do I have dreams
Financing of dream institutes yielded results, because we know a lot about the functioning of the brain during rest, about the visualization of visual images in relation to human emotions. We even learned to visualize the dreams of a sleeping person by connecting him to special computer programs. But the simplest question remains unanswered: “why or why did a person get the ability to see dreams?” Is this the result of the work of the subconscious mind with consciousness? Or maybe dreams really help to better absorb the information received per day, to heal deep-seated injuries? Some scientists still believe that dreams are nothing more than nerve impulses of the brain.
8. Why does a giraffe have such a long neck
This animal is considered one of the oldest mammals during our civilization, since its no less gigantic ancestors were found during the reign of prehistoric (preglacial) animals. Until now, science is pondering the topic of why nature has endowed this particular animal with a long neck. It would seem that the answer is simple - to easily get leaves growing high on trees. But because of the lack of foliage in the district, the giraffe can fully enjoy the low-growing greenery. Officially, scientists have not announced the exact answer to this simple children's question.
7. Why are most people right-handed
Somehow we are all used to the fact that 90% of the world's people are right-handed. Well, it happened and it happened, and "talent" is fixed thanks to parents and kindergartens. Interestingly, for more than 1.5 centuries, scientists have been struggling to unravel this mystery, linking the work of the limbs to the functioning of the cerebral hemispheres, etc.
6. Why yawning is contagious
On this issue, theories are put forward regularly, but many do not stand up to criticism. Someone strikes into discussions on the topic of “collective unconscious”, others discerned the close emotional and social connections of people with each other, a kind of “yawning empathy”. It was also noted that schizophrenics and autists are not inclined to “pick up” the wave of yawning that has begun in the crowd, possibly because they are deprived of that notorious social connection. So far this is the only argument of scientists. But the second question immediately arises - why exactly does yawning help establish any emotional connections?
5. Why do moths accumulate in the light
A small child can and can be fooled, explaining that the insect on the light bulb is just warmer. But adults are still tormented by the question of why these representatives of the fauna masochistically rush at a light source that can kill them (high incandescent temperature). The theory was put forward that light acts as a kind of locator for insects, so they fly up to it at a certain angle. But the opponents give a healthy argument, breaking the theory to smithereens - even before the invention of the lamps there was a fire that would quickly destroy all curious moths until the population disappears.
4. How many years can a person live
Many would like to know the answer to this question. We are told how much we could live, giving up bad habits, work, neurosis and unhealthy food, but at the same time, the final possible resource of the body has not been determined. Many scientists still consider cell deterioration and aging a disease that can and should be treated. Perhaps modern medicine has come close to the answer to this serious question, because it is already known about the existence of drug concepts that can extend life to 120 or more years.
3. How do birds know where to fly
A good question for any attentive person who noticed how clearly, harmoniously and organized the birds gather in flocks for flights to warmer climes. Note that they immediately fly to winter precisely to the south, and often to the same places. But the birds do not have navigators and maps, and beacons on the way are not able to install. How do entire groups manage to get to their destination, and then come back home a few months later? The only argument of scientists is that birds submit to the effects of the magnetic field of our planet.
2. How do parts of the body “understand” that you no longer need to grow
We all saw how famously a lizard is able to regenerate its tail by growing a new one. Interestingly, her body is able to control the process of creating a new tail of the desired structure, length and even shade. And what about such "complex matter" as man? How do his organs and body parts realize that they can no longer regenerate or grow? Nails and hair will grow as much as you like, until a person puts them in order, which can not be said about teeth, limbs and bones. Scientists note that a certain body signal gives a command to stop the development of protein mass, which prevents further growth. But just what kind of signal is it, who shapes and feeds it, on which channels?
1. What is at the bottom of the ocean
You thought you knew the answer to this question - but not at all. Only one thing is known - during the time of civilization we managed to investigate only 5% of the ocean floor, so we can judge the remaining 95% with a stretch. We still have a lot to learn about the flora and fauna of the underwater space, marvelous finds, unique deposits of natural materials and so on. The development of the ocean floor will answer a number of other important questions, for example, regarding the search for ancient sunken civilizations, the possibility of creating underwater cities and transport lines, etc.
Our world is huge and unique, so you should never stop in cognitive and creative activities. It is our “pochumuchki” that inspire scientists and research to new exploits, inventions and clues that are so important for understanding the world.
