Inventory of the top 10 birds that easily kill humans in seconds
For most people, birds usually rank very low on the list of the most feared animals, and rightfully so, after all, most birds are too small and lack natural weapons to cause serious harm to humans. They come in many varieties, sizes, and colors, and for their part, they've been used in practically everything - from business logo designs to government and political party emblems, to high culture and accessories, and many other things. But size and strength aren't the only weapons birds use to kill, dagger-sharp beaks, incredibly powerful claws, and even poison are in their arsenal, not to mention the sheer amount of power. Anyone who has been dive-bombed by a mad crow or a seagull will know this, just as everyone knows the traditional movie The Birds.

my country's manned moon landing may be ahead of schedule. Experts mention the lunar rendezvous and docking plan for the moon landing, which can be realized on the fifth day of the year.
At the China Aerospace Conference on April 25 this year, Mu Yu, director of the General Design Department of the First Academy of my country Aerospace Science and Technology Group, first introduced the Long March 9 that my country is developing, saying that it has a diameter of 10 meters and a lunar orbit carrying capacity of not less than 50 meters. It will provide important support for the establishment of lunar bases and the completion of larger-scale lunar exploration projects in my country's lunar exploration and lunar landing activities. But when he introduced these, he also said another manned lunar landing method, that is, at the current stage, if our country uses the method of circumlunar rendezvous and docking, and disperses the pressure of rocket launch through a comprehensive plan, then the low-Earth orbit carrying With a capacity of 27 tons, the goal of manned moon landing can be achieved, and the rockets it uses do not need giant rockets like the Long March 9.

The earth once had a rain of more than 10 million years. Will such weather still appear in the future?
If one day you can take a time machine to the earth 4 billion years ago, then for you, this is definitely a purgatory-level existence. At this time, the earth not only has no plants in the mountains and fields, but even low-level creatures. It is a planet made of magma, and the scorching high temperature bakes you, making it difficult for you to survive here for even a second.

Might the origin of life have something to do with it? Earth is the only known planet with plate tectonics
Earth's plate tectonic movements have profoundly influenced the nature, behaviour and evolution of the Earth, but there has been no definitive answer to the question of when plate tectonics began. The timing and mechanism of the initiation of Earth's plate movements has been a highly debated scientific issue in the field of tectonic geology. The study suggests that plate tectonic movements may have occurred on Earth at least 3.6 billion years ago or even earlier.

All people are born of parents. How did the first man and woman come to be before humans came into existence?
At different stages of human development, we have different explanations for the origin of mankind. At the dawn of human civilisation, the limitations of human observation and scientific and technological conditions doomed mankind to be unable to explain this question, but imaginative people invented an answer by suggesting that man was created by a higher order of beings, for example: our country believes that Nuwa Fuxi created man, while the Bible suggests that man was created by God, an idea known as " Creationism".

What is the meaning of life when it is all destined to die?
What is the marker that separates humans from animals? Is it the external physical form? Is it a complex and varied form of communication? Or is it the relatively elaborate habits of life? The answer is none of these, for the true mark of distinction is thought.

价值700亿亿美元小行星被发现，平均每人930亿，为何无人开采？
Introduction: With the continuous development of the economy, various countries have gradually withdrawn the banknotes belonging to each country for the sake of economic stability. The banknotes implemented by various countries have their own values, but if we say that the world is universal, it should be gold. Gold is a very precious metal on earth, and because gold is relatively rare, its value preservation rate is also very high.
