8 natural scientific phenomena cannot explain

Clay rock, sand dunes that know how to sing, curved forests are among many mysterious natural phenomena that people cannot explain.

Sound of sand dunes

According to Mother Nature Network, many sand dunes in the desert of Africa, China, Qatar and California, USA, emit high-pitched sounds, like the buzzing of bees or Gregorian chant melodies.

Scientists found that the sound from sand dunes depends on the size and speed of sand movement. But they cannot explain the cause of the phenomenon.

Star mucus

Star jelly is a sticky liquid, strange mucus falling from the sky, often appearing on fields and lawns after the meteor shower. Scientists do not know what this liquid is, because it dissipates quite quickly before being taken for analysis. The origin and chemical composition of star mucus is still a great mystery for researchers.

Lightning

Lightning is a special form of lightning , looks like a ball of light floating in the air. It is about the size of a golf ball to a soccer ball, does not generate heat and sound.

In 2012, Chinese researchers recorded a high-speed video of lightning strikes and photographed its emission spectra for the first time. The analytical results show that clayey clay is produced by minerals evaporating from the soil. However, many people believe that such a single observation cannot explain the whole cause of rock lightning.

Lightning Catatumbo

Catatumbo lightning is a natural phenomenon that occurs on a swamp in the area of Catalumbo that pours into Lake Maracaibo, Venezuela . This is also the place with the most lightning in the world. Thunderstorms usually last 10 hours per night, with an average of 28 lightning strikes per minute.

Some argue that thunderstorms appear constantly due to the hot mass of coastal air exposed to cold air across the Andes. Many others believe the phenomenon may be related to methane (CH4) emissions from Lake Maracaibo.

Curved forest

The curved forest (Crooked Forest) in West Pomerania, Poland, is a land containing about 400 pine trees bent 90 degrees at the base, while the trunk grows vertically. The cause of this phenomenon has not been clarified yet.

One theory was that a group of people bent trees after planting them in 1930. They hoped to be able to produce furniture from curved trees and intervene in the development process when young trees are 10 years old. . But the outbreak of World War II prevented them from harvesting wood, leaving the forest as strange as it is today.

"Wow" signal

In 1977, Dr. Jerry Ehman discovered the signal "Wow!" while participating in the Search for Extraterrestrial Intelligence (SETI) project. The strange radio signal lasts 72 seconds and never repeats. It's called Wow! because this is the word Ehman wrote on the printout of the signal.

Signals seem to come from the constellation Sagittarius, about 120 light-years from Earth. The scholars are not clear whether it is caused by aliens or not.

Devil's Kette wormhole

The Brule River flows through the state of Minnesota, USA. When it came to Judge CR Magney State Park, the river was split in half by a central rock rising into the Devil's Kettle double waterfall. A waterfall flows into Lake Superior, the other falls into a deep hole called the Devil's Kette and disappears right there.

Scientists believe that there must be an end point for the flow into the deep hole. They did all sorts of things like pouring dyes, dropping table tennis balls and logs into the Devil's Kettle pit, then waiting for them to float on Lake Superior's face. However, everything in the hole disappeared without leaving a trace.

Globe of light

In the valley of Hessdalen , central Norway, there are often strange light spheres of different colors and shapes. They sometimes flashed and flipped off, moved quickly or floated in the sky. Scientists call this "Hessdalen light", named after the valley where they occur. The time when Hessdalen light appears most often can be 10-20 times per week. Until now, researchers have been searching for the source of energy and the cause of the phenomenon.
