Factual science fiction facts but true

Discover the wonders of nature through some interesting scientific phenomena.

Surprise with the truths of fictional but true science

Nature always contains countless wonderful things and interesting facts. It is possible that the secrets stored in the distant universe or sometimes are extremely close to human life.

Today, thanks to the ever-growing development of science and technology, people have been able to touch those secrets, partly to help improve the quality of life.

1. Meteors destroy trees but the ground is intact

The Tunguska event is also known as the " Siberian Big Bang" , which took place on June 30, 1908. According to recorded documents, on that day, an asteroid entered the Earth's atmosphere with speed. about 54 thousand km / h and exploded at an altitude of 8.5 km above the ground.

The explosion of energy equivalent to 185 atomic bombs was dropped on Hiroshima city, destroying more than 60 million trees within 2,150 square kilometers.

The strange thing is that although the entire trees within the sphere of influence are destroyed, the surface of the ground in that area is not affected at all.

2. Many planets float in the middle of the universe without belonging to any solar system

For meteorites this may not be a strange phenomenon. However, a planet that can exist without belonging to any solar system is a matter of 1-0-2.

Many hypotheses are proposed to explain this phenomenon. According to experts, these planets have been "excreted " from the solar system and have to drift from the early stages when they first form.

3. Once upon a time, the Mediterranean did not have a drop of water

Geologists said that this was an event that took place 5.5 million years ago, caused by the connection of two continents of Europe and Africa and closed the path leading to the Atlantic Ocean of the Sea of ​​the Sea. China .

Over thousands of years, seawater slowly evaporated until there was no more water left. It took about 200,000 years later, a massive flood named Zanclean flooded a piece of land connecting Europe and Africa, from there connecting the Atlantic to the Mediterranean.

4. In Australia, there was a 'rain of animals'.

You believe, not only fish but also spiders, frogs and many other animals have followed the "landing" raindrops on the ground. This strange phenomenon shocked many people, even felt anxious and saw this as a sign of the Apocalypse.

However, according to experts, this is a scientific phenomenon. The most favored hypothesis is that these animals have been sucked up and swept away by a tornado or swirling winds somewhere.

After that, they were dropped again in a strange land, sometimes far from the places where these animals sucked up into the sky hundreds and thousands of kilometers.

5. There are 'immortal' storms in Lake Maracaibo, Venezuela

The Maracaibo Lake in Venezuela is the place to witness more thunder storms , with the amount of lightning that can generate 1 million volts of electricity annually.

Accompanying them are storms that occur about 150 days a year and last 10 hours a day. This phenomenon contributes to the production of large amounts of ozone in nature.

According to experts, the cause of this phenomenon is the Catatumbo river on the way to Maracaibo lake which has flowed through a swamp containing many decomposed organic substances.

These organic substances release large amounts of methane , combined with the uranium emitted from the surrounding rocks, creating endless storms.

6. The existence of fire storms

Have you ever imagined that these frightening whirlwinds, accompanied by an immense amount of fire, would be like a " winged tiger" .

These fire storms stem primarily from the phenomenon of large forest fires. When there is a fire, high temperature increases the speed of moving gas molecules to create extremely large winds.

Furthermore, there were oxygen inside the whirlwinds, the energy that helped to sustain the fire of the fire. The above factors combine to create extremely terrible fire storms, not only bring heat but also terrifying destruction.

7. Ancient dragonflies are about the size of albatross

These giants have the scientific name Meganeura - the ancestor of the dragonfly today. Giant dragonflies lived in the period of about 300 million years ago, with food mainly of smaller insects.

Scientists are still studying why such large insects can thrive in that time. If they existed in this day and age, it would certainly be a nightmare and no one would dare to let the dragonfly bite the navel to swim.

8. Koala bears have more than one genitals

Koala is a special bear that only lives in Australia , and is also one of the symbols of the country, besides kiwi and kangaroo kangaroos . This is a very gentle bear and only eats leaves and fruits.

Just like a kangaroo, a mother koala will often put a newborn baby bear in a bag in front of her stomach. But what is special about this bear is not only that.

The male koala's genitals consist of 2 pieces, while the female bear has 3 female sexes - 2 female bear's vagina will be used to receive sperm from the remaining two males and vagina used for childbirth.
