No matter the earth or the universe, what human beings know is only the skin. After all, the history of human beings on the earth is only a few million years, which is insignificant compared with the history of the earth in the universe. Since the new development of science and technology, human beings are devoting themselves to some unsolved mysteries. It is uncertain where the future of mankind will go. Through careful discussion, scientists are surprised to find that there are four undisclosed truths on earth, each of which is frightening. So what exactly?

The four serious problems on earth are related to the fate of mankind, and the truth behind them is frightening! First of all, the first truth is that most of the satellites launched by human beings are garbage. In 1957, the Soviet Union launched the first man-made satellite, and more and more countries launched satellites into space. Up to now, there are thousands of man-made satellites around the earth, and only a few of them can operate normally. These garbage pose a certain threat to human beings. In the process of observation, scientists are attracted by this Some space garbage blocks the view. Once there is an accident in space, the debris may fall in densely populated places, causing certain danger. Therefore, scientists are trying to eliminate space garbage.

The second truth is comets. Although comets are beautiful on the surface, they are actually very terrible. When comets cross the earth, they make people feel very good-looking. If a large area of comets fall on the earth, the disaster will be unspeakable. Once dinosaurs died out, it is very likely that comets hit the earth. In 1994, there was a satellite flying towards the earth. Fortunately, Jupiter attracted it, otherwise it would fall on the earth and probably experience the fifth mass extinction. All this is very terrible.

The third truth is the life span of the earth. Although the earth has a history of 4.6 billion years, human behavior has caused indelible damage to the earth. Many people have always believed that the earth can not be destroyed, but all kinds of human actions on the earth have seriously affected the earth. Global warming, air pollution, water pollution and so on will cause certain damage to the earth. At that time, the earth will no longer be suitable for human survival, and human will become homeless.

The last truth is the mass of the earth, which is beyond human estimation. Some people will say that the mass of the earth is 6 trillion tons, but this is only an estimation, and it is an answer that scientists have worked out through long-term calculation. As for its real mass, science can’t measure it. If it can be calculated one day, science and technology have reached the peak stage, which will greatly promote the subsequent calculation of other stars.

I have to say that there are too many mysteries in the world that can not be solved. Whether human beings can successfully fly off the earth in the future is a question that needs to be considered and worth pondering. What do you think of it? You can leave a message for interaction.
