Generally speaking, the difference in volume and mass between the satellite of a planet and the planet itself is several thousand times or hundreds of times, while the difference in volume and mass between the moon and the earth is only dozens of times, which makes scientists feel very puzzled. Scientists believe that if the earth can't capture the moon according to the gravity of the earth, how did the moon become the satellite of the earth? Some scientists think that maybe in the early solar system, a huge asteroid hit the earth, knocking out a small part of the earth, and this knocked out part became the moon. Although this is only a scientist's guess, it is also reasonable.
In order to explore more mysteries of the moon, scientists have also made a lot of efforts. For example, humans landed on the moon many times and brought back lunar soil. 1969, NASA Apollo 1 1 landed on the moon. Since then, humans have gone to the moon for research many times, but it was unexpected that American scientists would blow up the moon. Gary V. latham, an American scientist, proposed sending a nuclear bomb to the moon with unmanned rockets, and then conducting a nuclear explosion experiment on the moon to prevent nuclear radiation from entering the earth. In addition, many scientists believe that it can be detonated from the back of the moon. Soviet scientist Yakov Zeldovich once proposed to launch a nuclear warhead on the moon.
Whether these nuclear bombs can blow up the moon or not, these ideas are hard to believe. Later, in 199 1 year, American scientist Alexander A-bian put forward the theory that there is no moon. He thinks that blowing up the moon can solve the problem of human survival on the earth. He believes that if the moon is blown up, the earth's axis will not swing in a period of 25,000 years, so the alternation of seasons will disappear. If there were no alternation of seasons, natural disasters on the earth would be reduced a lot. Although his idea is very good, but if there is no moon, will the environment of the earth really be the same as he said?
In fact, the moon is very important to the earth. Because of the existence of the moon, the probability of the earth being hit by an asteroid is greatly reduced. We know that 65 million years ago, an asteroid with a diameter of 10000 meters hit the earth, causing 90% of the life on the earth to perish. At that time, the overlord of the earth was dinosaurs. After the extinction of dinosaurs, creatures began to evolve again, and humans were born after the extinction of dinosaurs. The moon can resist the impact of asteroids on the earth. When many asteroids are close to the earth, they will be attracted by the gravity of the moon and then hit the moon, so there are many craters on the surface of the moon. Simply put, the moon can also be regarded as the protector of the earth.
In addition, the moon will slow down the rotation of the earth. In the solar system, all the planets are spinning. It takes about 24 hours for the earth to rotate once, and about one year for the public to rotate once. However, scientists calculated that the earliest rotation time of the earth was not 24 hours, but 6 hours. Later, influenced by the gravity of the moon, the earth's rotation speed slowly decreased, and now the earth's rotation has become 24 hours. If there is no moon, it is 24 hours.
And the moon is of great significance to human exploration of the universe. The moon is the closest celestial body to the earth. Now humans explore the moon the most. China's Chang 'e V probe brought back soil from the moon. After analysis, scientists found that there were signs of volcanic activity on the moon 2 billion years ago, which indicates that the interior of the moon may be similar to the environment inside the earth. Maybe the moon was once really a part of the earth. It was just knocked out and turned into the moon. In addition, scientists found a rare energy source on the moon. This energy source is helium -3, which is the main fuel for nuclear fusion. The reason why our sun can burn for so many years is the reaction of internal nuclear fusion.
Scientists have come to the conclusion through research that nuclear fusion reaction can only be realized in high temperature and high pressure environment. When atoms in the sun collide with each other, they will produce new nuclei and lose some nuclei, which will be converted into energy. Four hydrogen nuclei in the sun converge to synthesize a helium atom when released, and its mass will lose 0.0276 units, which is equivalent to 0.0069 units for one gram of hydrogen. These lost masses will be converted into energy and released, and then absorbed by other celestial bodies. The earth receives only 2.2 billion solar energy in one second, and this 2.2 billion energy is equivalent to the total energy of 65.438+0 million tons of coal burned on the earth.
It can be seen that the energy produced by nuclear fusion is very huge. At present, scientists are actively studying controlled nuclear fusion, but controlled nuclear fusion needs a lot of helium -3, and the reserves of helium -3 on the earth are very small. However, on the moon, the reserve of helium -3 is about 6.5438+0 million tons, which is enough for human use. Therefore, human beings will definitely develop the moon in the future, but human science and technology can't reach it at present. The moon is very important to the life of the earth. If we blow up the moon, it will have a great impact on the earth. After the moon is blown up, a large number of moon fragments will fall to the earth, which will seriously threaten the life of the earth, and its power is no less than the fifth extinction.
However, according to the current human technology, it is impossible to blow up the moon. After all, the power of human nuclear bombs is limited. Scientists have calculated that it takes 200 times the power of nuclear bombs around the world to blow up the moon, so it is impossible to blow up the moon with nuclear bombs owned by human beings at present. In the future, with the progress of human science and technology, mankind will build their own home on the moon, and the moon may become the second home of mankind. So it is no good for human beings to blow up the moon. I hope that mankind can solve the mystery of the moon as soon as possible, establish a base on the moon and let human civilization develop for a long time. Do you have anything to say about it?
