VIVA – Science and technology may have brought progress to human civilization. This includes exploring space, solving the Egyptian pyramid puzzles.
However, there are still many natural phenomena that science can not explain. Scientists try to investigate to get an explanation, but the results are only up to the stage of the theory, although they have not yet reached a definitive answer.
Here are nine natural mysteries that science has not yet answered.
1. Why do people yawn
Yawning is something that you could do every day. But scientists still do not understand why that happened.
Quote from Science AlertRecently, the scientific community has the idea that yawning is a thermoregulatory behavior that cools the brain, but its true biological function is still unclear.
What's more, scientists have also found no answer why contagious yawning occurs among people.
2. Mushrooms Chorioactis greenhouse grows only in Texas and Japan
Chorioactis aster is the only type of fungus in the genus Chorioactis and is only found in Texas and Japan.
Both locations are on the same latitude, but mycologists can not find out why this fungus only grows at these two points.
3. The north pole of Saturn rotates in the form of a hexagonal storm
At the north pole of Saturn there is a weather system in the form of a strange hexagon. The storm was photographed and observed for years by NASA Cassini, but remains mysterious.
4. Humpbacks change traits of individual beings into groups
Humpbacks are usually lonely, but in recent years they have joined groups from 20 to 200 off the coast of South Africa. That is according to a 2017 study from the University of Pretoria.
Marine scientists are not sure why the nature of these ancient creatures has changed. Some speculate because of the increasing population.
5. Curved trees in the Dancing Forest in Russia
The forest in the Kaliningrad region becomes the Dancing Forest & # 39; named because there are many pine trees that curl into spiral shapes, rings and other configurations.
They were planted in the 60s and are the only tree species that exhibit this behavior.
According to Atlas Obscura, different theories say that the causes are extreme wind, unstable ground and disorderly caterpillars. Locals call it "Drunken Forest".
6. Why snoring cats
Scientists understand how cats snore, but still do not know why they did it.
The reason why cats snore is still being discussed. One hypothesis states that snoring promotes bone growth because the frequency of vibrations causes the bones to harden in response to pressure.
