Don'T Forget That You Are A Cosmopolitan

The vast and endless starry sky, which used to exist only in books, is often a few billion light-years away. Everyone feels that it is out of reach and has little connection with their daily life. However, scientists have been exploring the mysteries of the universe. With the continuous progress of space research such as landing on the moon and exploring Venus and Mars, we have accumulated enough knowledge to understand the relationship between human beings, the earth and other stars in the solar system. Jim Bell's Ultimate Guide to interstellar travel is a science fiction book that introduces the knowledge of the solar system. The text is about the situation that the earth people will face 50 years later when they have begun to colonize the moon and travel on other planets. If you think it's a bit unreal, you can read a lot of interstellar knowledge in the book and watch a lot of precious pictures taken by satellites and probes.

In the solar system, all stars and life revolve around the sun, forming a unique law of life and production. Venus is closest to earth, and they are close in size and gravity coefficient. Living on Venus may not be out of the question, but you need to be able to make your own oxygen. Moreover, because the atmosphere of Venus is full of carbon dioxide, the greenhouse effect is very obvious, resulting in the absorption of solar radiation can not be emitted, Venus surface temperature as high as 460 degrees Celsius. Humans can only float more than 50 kilometers above its surface to build floating dwellings, where the temperature and gravity are close to the earth. Interestingly, it takes 243 days for Venus to rotate on its own, 18 days more than it does around the sun. This means that it takes 243 days to see the sun rise from the west to sunset in the East, and the residents there have experienced "spring, summer, autumn and winter" in this long "day". I'm afraid that people on earth can't adapt to this inverted schedule.

Even if the oxygen and temperature problems are solved, Venus will not be able to feed humans because it cannot provide food. But Venus is very valuable as a reference for environmental change. We can imagine Venus as the ultimate form of environmental deterioration on earth. After acid rain and greenhouse gases occupy the atmosphere, there will be no more life on the earth's surface. Climate warming has become an important issue of global concern. We know that solar activities and greenhouse gas emissions will affect the earth's temperature and climate. The former is mainly due to the change of sunspots, which will have an impact on the planets of the solar system, especially for human beings. Sunspot activity affects the earth's climate in three ways: the change of atmospheric ionization degree, the difference of thermal radiation, and the change of geomagnetic field.

Climate change is not only likely to cause large natural disasters, but also seriously affect the production of agriculture, animal husbandry and fishery, which in turn leads to cyclical fluctuations in economic activities. In fact, economists have found that human economic activities depend on sunspot activities. Sunspot activity is measured by the number of sunspots. Starting from the year with the least sunspot number, the sunspot number increases in 3-5 years and reaches the peak. During this period, the solar radiation increases, forming El Nino phenomenon. The more inactive the sunspot, the stronger this phenomenon is. The sunspot number decreases in the following 5-7 years, reaching the bottom, which lasts for 8-11 years, which is called Schwabe cycle or sunspot cycle. On this basis, because the sunspot magnetic pole changes every 11 years, the two sunspot cycles of 22 years are called Haier cycle or solar magnetic pole cycle. The longest cycle of solar activity is 55 years, which is called the Jicun cycle or the solar cycle.

Interestingly, since agriculture, animal husbandry and fishery are basic industries and provide important raw materials for the secondary and tertiary industries, they have a chain reaction under the influence of solar activities, and corresponding economic cycles are formed. For example, the 3.5-year inventory change is called the kichin cycle, the 11-year sunspot cycle corresponds to an investment cycle, called the zhugela cycle. The 22 year solar pole change corresponds to the construction investment cycle, which is called Kuznets cycle. The 55 year solar cycle corresponds to the famous combo cycle.

Sunspot activities affect the temperature and rainfall in different parts of the earth, leading to price fluctuations of agricultural products, which is most fully reflected in a sunspot cycle. When the number of sunspots is small, that is, the solar activity is not active, the prices of agricultural products reach a relatively high point. According to the author's calculation, the world's major countries are currently in the sixth solar cycle, and the number of sunspots has also been reduced by space observation, which confirms this speculation, indicating that the world is entering or about to enter a new conbo cycle. According to the general law, the first 30 years or so of this cycle is an economic rising stage driven by technological innovation, which is also the main reason why all countries are seizing the commanding heights of science and technology at present. The golden development stage of the next 30 years belongs to a big country of scientific and technological innovation.

In addition to the influence of the sun and moon, the earth will also be affected by gas planets. Some phenomena cannot be explained from a scientific point of view. Not only the crops and animals on the earth will be affected, but also the psychology and physiology of human beings will change periodically in response to the relative changes of the cosmos. This is what the ancient Chinese philosophy called "the unity of man and nature". The mystery remains to be revealed by future scientists.
