The lungs of the earth, the Amazon rainforest, the paradise of animals is a forbidden zone for human beings, and there are dangers everywhere
As we all know, human beings have not yet fully explored the "underwater world", and the depths of the ocean are unknown and mysterious to us.

Dragonfly: The "king" of flying, scientists have been studying for decades, but have been unable to understand its technology
When people talk about objects that can fly freely, people generally think of birds and airplanes. Birds are small animals that are born with the ability to fly, and airplanes are our most outstanding inventions in modern times. in the infinite sky.

变异毒株出现后，“拔牙”将面临失效
When the ASF outbreak occurred for the first time, the major pig farms came up with a "tooth extraction" plan based on biosafety through repeated practice. As soon as this plan came out, major farms scrambled to imitate it, and the effect was satisfactory. However, due to the emergence of the natural variant of African swine fever genotype II with low lethality, the plan encountered serious challenges: failure or high culling rate.

Fusion Engineering Dilemma
1. Fusion research and tokamak devices The established goal of fusion energy research is to develop a new type of electrical energy based on the theory of nuclear fusion, the principle of which is the same as the heating principle of stars such as the sun.

From dwarf to giant: the height is 1.27 meters before the age of 21, and it grows to 2.34 meters after the age of 21, the only case in the world
In "Alice in Wonderland", the girl Alice once ate a kind of biscuit, and her body became so huge that it could break through the house; and after eating another kind of biscuit, Alice's body would become smaller, like a Insect ants. Such fantastic things will probably only happen in the fairyland in the dream, but in reality, there have been people who have both dwarfism and gigantism at the same time.

The second largest planet in the solar system - Saturn, the planet that rains "diamonds"
Can diamonds be mass-produced on Saturn? Can. Under the upper atmosphere of Saturn, a large number of water and gas clouds are constantly dancing, and the super lightning flashes turn the methane gas into a large cloud of soot. The downward pressure increases, and these soots accidentally turn into diamonds . As the saying goes: a grain of Saturn's ash on your head may be a diamond, but don't think too much about it, these diamonds quickly disintegrate and eventually liquefy under the pressure of Saturn. Forty thousand kilometers below Saturn's surface, take a look at its largest source of energy. The pressure here is very high, the gas looks like liquid metal, and the molten helium rains down in the hydrogen, releasing an amazing amount of heat. This is a very specific heat source, like the engine of Saturn's weather.

There have been at least 2 supernova explosions around the earth, which have caused biological extinction. What should humans do?
According to the research, scientists have found that in the past 10 million years, there have been at least two supernova explosions around the earth, and in the process of supernova explosions, the released energy reaches the earth and precipitates in the earth's strata, allowing scientists to have Opportunity to discover the occurrence of disaster through geological survey.

Sea spiders with legs below their real head: I did it with my legs for giving birth
There are millions of creatures living on the earth. They seem to be unrelated in the whole process of life. In fact, they are in a complex chain of intertwined and tangled organisms. There are interdependence and cooperation between them, and there is a relationship of resistance and predation. The complex and ever-changing human connections are changing every day. The interlacing and integration of nemesis foraging and cooperative survival has completed the stable balance of nature. And there is such a creature called "no nemesis in the whole ecosystem", have you heard its name? That is the long legs of the deep sea - the sea spider.

Anomalous elements appear on stars, physicists speculate: or alien civilizations are dumping garbage
In the universe, only stars and above-level planets emit light, because they are constantly undergoing nuclear reactions inside them, and then radiate photons to the outside. Astronomers can learn basic information about a star by observing the conditions of the stars in the universe. But in the process of exploration, scientists also found some exceptions. For example, there is a special star in the constellation Centaurus about 355 light-years away from the earth. Scientists suspect that it is related to alien civilizations.

There is time for physics to be easy to learn and time to revisit our ancient emptiness and scientific vacuum
In physics there is the concept of a vacuum. A vacuum is the absence of matter in space. A container can be evacuated into a vacuum container. The universe is a vacuum in which various celestial bodies operate.
