Was there really a "prehistoric civilization"? Evolution to be disproved? Scientists: Human civilisation is cyclical
The course of human evolution may seem clear and unambiguous, but scientists have found evidence, such as frescoes, fossils and the remains of civilisations, that seem to indicate that it was quite uncomplicated, and may even directly disprove the theory of human evolution that people have believed in for centuries.

Hubble telescope captures fast radio bursts from space; are they wireless signals from aliens?
The Hubble Space Telescope has recently tracked five signals of fast radio bursts originating from very distant galaxies. There is no clear explanation for the origin of the fast radio bursts, which could be supernova explosions, magnetar signals, or possibly radio signals from advanced alien life.

The mysterious Bermuda rumoured on the internet has been smashed through its disguise by a diving enthusiast who has taken the mystery out of the sea
The mystery of the Bermuda Triangle, as we know it, is not so mysterious in itself. It's just that because of the number of "strange" things that have happened in the area, and the media's ability to spin it, many people think it's extremely dangerous and mysterious, but it's not. On December 5, 1945, a formation of five USAF TBM Avenger fighter jets was involved in an accident in the Bermuda Triangle, and while flying over the area, all the fighter jets in the formation disappeared.

The most unbelievable creature on Earth! Able to withstand super impacts and survive in space
There are many incredible creatures on Earth, such as the water bear worm, a slow-moving animal known as the "little beauty", which is an unbelievable creature that, despite its small size, has the ability to adapt to its environment and resist stress. They may be tiny, but their ability to adapt to their environment and resist stress can be described as "uncanny".

Why don't people eat carnivores, but only herbivores?
Now that the Chinese have largely solved the problem of food and clothing, people in many regions are no longer just looking for a full stomach in their diets, but for a balanced and healthy diet. This is especially true for people who are dieting and working out, whose recipes are more regular and lighter than the average person's, basically consisting of vegetables, fruits and vegetables and protein-supplemented meat such as chicken. Even for those who don't work out, meat is usually included in their regular recipes, but our meat usually comes from poultry and livestock, which are basically herbivores or omnivores.

This planet in our solar system may contain more water than Earth and is likely to have advanced alien life
During this period of time, everyone has been following the news of Tianwen 1 and Zhu Rong, our country's first mission to explore Mars, and now the Zhu Rong Mars rover has also left the landing platform and driven to the surface of Mars to drive and start patrolling to explore Mars. We have done an excellent job of orbiting Mars, landing on Mars and visiting the planet in three major steps in this mission. The Utopian Plain, the landing area of the rover, is the largest plain on Mars and previous research has shown that there is a large amount of water beneath this large plain, although due to the very low temperatures on Mars, this water is mainly in the form of water ice material.

In terms of volume, Jupiter is not much bigger than Saturn, but in terms of mass, Saturn is far less than Jupiter, as Saturn's mass is about 5.6834 x 10^26 kg, while Jupiter's mass is about 1.8982 x 10^27 kg.

Uranium is an important raw material for the use of nuclear energy, but it is also a radioactive element that decays. Why does uranium decay? This begins with the microstructure of the atom.
