The plane channel can actually attract some inherent substances. Whether it is some treasures or some precious medicines, those things can pass through the plane channel. These resources are the most powerful for the psychics on the earth. Treasure...

Because of this reason, the entire earth was caught in the competition for these plane channels. After all, whether in reality or in the superpower world, resources are limited, rather than rebirth in infinite ways. Some top resources If you use a little, you will use a little less. If you use a little less, you will definitely use a lot less.

In this way, whether it is for the sake of one's own strength or to prevent others from occupying these resources, a round of struggle is inevitable.

In this case, especially after the psychics are awakened greatly and the number of psychics increases, the dispute will become more serious. This situation is similar to a period of history in reality.

In 1798, British economist Malthus published his book titled "Popularity of Population". The central idea of ​​this book is that population growth can be infinite, but the amount of food is certain. In limited cases, the population will exceed the level that food can bear. Since the growth of food cannot keep up with the growth rate of the population, natural disasters such as war, plague, and famine will accompany humans.

Malthus's "population theory" caused a huge social response at that time, and also had a profound impact on later generations' research on population. In the century, the British economist Keynes's theory of effective demand was attributed to Malthus's "effective demand theory". In an important inspiration, Keynes called Malthus "the first Cambridge economist" and "having profound economic intuitions can not only keep an open mind about the changing experience picture, but also continue to use his normative ideas. The principles in explain experience”.

In 1796, Malthus wrote an article titled "Crisis, a Constitutional Supporter's Perspective on the Recent Interesting Situation of Great Britain", which was about socio-political and economic issues, including population issues, but no one wants to publish the book. .In 1798, Malthus published his "Popularity" when he was 32 years old. The title of the book is "Popularity Theory; The Impact of Population on Future Social Progress; Commentary on the Theory of Mr. Gerdervin, Mr. Condorsey and other authors". In 1803, Malthus supplemented and revised the "Popularity" and published the second edition under his real name.

In 1793, British philosopher Gordwen published "Political Justice", which criticized the current social system from the standpoint of ruling axeism. Gordwen proposed that improving society with justice will eliminate all sins and poverty, thereby achieving rationality. The complete state of human society. In 1794, French philosopher Condorcet published "The Evolution of the Human Spirit", which advocated that the evolution of human spirit promotes human evolution, and believed that the poverty of the people is caused by the defects of the social system. Therefore, it is required to improve the social system.

Malthus started by criticizing them, believing that human poverty and sin did not come from the system, but from the different growth of population and food. He linked population problems with the future of mankind and believed that it was "research because of rapid population growth." The obstacles caused by the improvement of human survival ability to the progress of human society."

In his book "Principles of Population", Malthus said: "I think I can make two reasonable assumptions. First, food is a necessity for human survival. Second, the ** between two surnames must exist, and almost

Will keep the status quo... Then, if the 2 premise assumptions I proposed are recognized, I can say that the population's proliferation is infinitely greater than the ability of land to provide human survival resources. Once the population is not suppressed, its growth will be

Geometric ratios are carried out. Living materials will only increase with arithmetic ratios. Anyone who knows arithmetic can see that the former has great power compared to the latter."

Malthus also said: "Assuming the world's population is an arbitrary value, for example, 1 billion, the population will grow at multiples of 1, 2, 4, 8, 16, 32, 6..4, 1(, 256, 512..., and

The living materials will increase according to multiples of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.... After 225 years, the ratio of population to the number of living materials will reach 512:10; after 300 years,

, will reach 4096:13, then after 00 years, the gap between the two will not be calculated, although the output of living materials will increase to an astonishing level at that time."

The publication of "Popularity" was a period of booming development in the Western Industrial Revolution. Malthus used two mathematical series to reflect the relationship between population and food growth, which was an innovation and basically summarized the basics of human social resource growth in the industrial era.

Characteristics. This idea of ​​Malthus has caused a huge response in society. The natural and economic circles have used this as a basis to publish many works and theories on economic and social development. Of course, Malthus's "Popularity of Population"

After the publication of 》, it also aroused criticism from some scholars.

In the early 1970s, with the assistance of a communications committee composed of 152 members in 58 countries, "Only One Earth" written by Barbara Ward and René Dubos was the first in Stockholm United Nations in 1972.

The unofficial report prepared by the Sub-Environmental Conference, which described: "The world's population gradually increased from the number of agricultural possible support levels in the Neolithic era to about 400 million. After 1,000 years, about 1,600 AD

In 2018, the population reached the first 1 billion. Since then, population growth has begun to accelerate. This is the result of the accumulation of momentum in the industrial revolution and increasing industrial and agricultural production. It is also the continuous decline in mortality rates, especially infant mortality rates.

The result of the decline. After only 300 years, by 1900, the population reached the second 1 billion. The third 1 billion only took 50 years (to 1950). By 1980, it only took 30 years,

We are about to reach the fourth 1 billion population figure." This result also seems to prove the theory that the Malthus population has grown in geometric ranges.

French economist Vallas said: "Malthus's population theory includes two aspects: one is that the population grows at geometric ratio, and the other is that the production of food and living materials will grow at arithmetic ratio, and the gap between the two cannot be bridged.

The first argument is almost absolutely correct. According to the general laws of reproduction in the biological world, the population will increase exponentially from the next generation. If there is sufficient living information, the population will indeed increase in geometric ranges. The growth rate of the population seems to be

It has become an indisputable fact. However, the second inference does not contain the correct surname as contained in the first inference. It fails to distinguish technological development from economic development and does not fully consider the impact of technological development on food production.

Because, if technical factors are added, food production and population will both grow geometrically, but the former is slower than the latter."

From now on, Vallas may be the first scholar to propose that technological development has an impact on social production, but he ultimately did not escape Malthus' conclusion. 40 years after Malthus's "Popularity" was published, Engels also discovered Malthus's thoughts.

The defects of the population, he believes: if the population grows exponentially, the labor force that produces food will also grow exponentially. Engels emphasized labor productivity and the ability of the population to use science and technology to meet needs, so the law of Malthus is not unchangeable. Engels corrected Malthus' conclusion

, This scientific conclusion has been proven by the practice of the development of science and technology in modern society.

Looking back on the history of England, from the plagues and famines that occurred at that time, Malthus had sufficient reason to arise the question of whether human society was destined to continue to suffer in the crisis of resources. All the food and fuel that nature provides for mankind to reach nature.

When the limit is that all arable land is planted, it is still not enough to eat, and humans will go hungry. Using the production technology of 1798, this is very obvious. In the view of classical economists, the land is extremely

The land restricts the growth of social wealth, and no society can escape the restrictions imposed by nature. However, after human society entered the industrial age, the situation has fundamentally changed. People have reduced the demand for land for producing food, which is not

The decrease in population has led to the improvement of land use efficiency, and compared with other resources, the most important production factor in the agricultural era - the economic and important surname of land - has dropped significantly.

In the classical economic growth theory, the analysis of the relationship between population growth and economic growth was basically pioneered by Malthus, and it was the first time he regarded population growth as an important part of the economic growth theory. Looking at Malthus

Come on, whether it is the limited surname of resources or the scarce surname of economics, they all exist absolutely. Malthus's idea is considered to be the absolute scarcity of resources. In modern economic growth theory, Malthus's theoretical model summarizes

For the "Malthus Trap".

After World War II, a pessimistic view on the development of the world's population was popular in the West. The main representatives and works include: j.w. Vogt's "The Road to Survival" (1949), j.o. Herzler's "The World Population Crisis" (

1956), p.r. Elridge's Population Bomb (1968), g. Taylor's The End of the World (1970), d.l. Meadows's Limits of Growth (1971), a.

Pechei's "The Future of the World" (1981) and so on.

They use population statistics, the growth rate of food, and the consumption of resources, and predict that the world today is facing the crisis of "human bombing", and believe that the "population crisis" will inevitably lead to "ecological crisis" and "food crisis".

"Resource Crisis", population growth has exceeded the carrying capacity of land and natural resources. These scholars warn this: If this situation cannot be controlled quickly and effectively, human beings will face a disaster like atomic bombs and hydrogen bomb explosions.

Almost a consensus conclusion: the root cause of these problems is the development of China's population growth too fast.

In 1968, Elridge, an entomologist at Stanford University in the United States, published the book "Popular Bomb". In the book, Professor Elridge asserted that it is predictable that given the increase in the number of people in the world, the earth will eventually not be able to feed humans.

.Popular Bomb begins with this text: "The battle to feed all mankind is over. In the 1970s, thousands of people will die of starvation in the world." Elridge also wrote:

“No one or anything can stop the sharp rise in mortality rates in the world.”

Since the publication of "Population Bomb", Professor Elridge has become famous all over the world. This book has sold millions of copies and was quickly translated into a variety of words and sold well in countries around the world. It has indeed achieved sensational results and has caused

People's panic about "people bombing" has had a great social impact.

Elridge is a downright pessimist, and his point is simple: he believes that in a limited space, resources will be exhausted, and that with you, there is no mine. He believes: Because of the explosive growth of people

, Humans have an increasing demand for food. In order to increase production, a large amount of fertilizer is applied to the land, which will damage organic matter, desertify and become barren. In addition, industrialization and urbanization have caused a large amount of arable land to be occupied and the grain output is reduced.

, the source of food supply will be more difficult.

In 1974, Elridge once again predicted: before 1985, humans will enter an era of resource scarcity, and many non-renewable mineral products that humans rely on for survival will be on the verge of exhaustion. Humans will destroy the mineral resources on the earth and create sincerity.

The consequences of disaster-like disasters. Humans cause damage to nature, causing serious air pollution and damage to the ecological environment. He believes that human bombs come from the third world, and the population of these countries develops too fast, causing unemployment, poverty, and resource exhaustion

, environmental pollution, etc., are the real reasons why the world is divided into poor countries and rich countries.

The development of society did not develop as Malthus and Elridge expected. As a scholar, Malthus was cautious and had doubts about the prediction of such a tragic prospect of mankind. At first, the articles were only published anonymously, while Elridge was a big deal.

Advocate.

Malthus's "population principle" is essentially similar to Elridge's pessimistic view of "people bombing". Malthus believed that humans must achieve population balance through war, plague, and famine. Elridge

It is directly recommended that the United States should not provide any food aid to the development of food shortages in China. Their doctrines and views caused great panic among people, and then they were full of doubts and fears about the development prospects of human society. What is even more terrifying is that

Some countries and political groups have absorbed and adopted their wrong views and opinions, and proposed to interrupt humanitarian assistance such as food to developing countries. This trend of thought has hindered the healthy and harmonious development of human society in a certain historical period.

History has not developed in the direction predicted by the Population Bomb. United Nations statistics show that since 1961, the world's per capita agricultural output has continued to increase, and the per capita agricultural output in developing countries has increased by 52%. People in some poor countries

Living standards are improving, the number of people with famine around the world continues to decrease, and the average life expectancy is extended to 67 years old. The fertility rates in various parts of the world have dropped significantly, and the fertility rates in developing countries have dropped from decline to decline, and the fertility rates in developed countries have dropped from decline to

.The new threat faced by humans is not the overpopulation, but the aging of the population due to the decline in fertility. In the 1980s predicted by Elridge, according to World Bank statistics, after deducting inflation factors, metals and mines

The average price of products has dropped by % and food prices has dropped by 50%, which means that the poorest people can also eat enough. The main problem in more and more countries is that people cannot eat enough, but that they have to spend money to lose weight.

and treat various diseases caused by overnutrition.

The human society has entered the 21st century, with a population of more than 6 billion worldwide, which has increased by more than 2.5 billion in 1968 when Elridge published the article "Population Bomb". The time has exceeded that of the people predicted by Elridge*

In the era of bombing, why haven’t resources been exhausted, and there are no thousands of people starving to death? Human society is not only not destroyed, but is still developing forward. Not only that, people’s bodies are healthier, their lives are richer, and their babies are

The mortality rate has dropped significantly and the life span of the population has been greatly extended, especially in the third world countries referred to by Professor Elridge. Of course, we have also seen that there are indeed some countries that are still in war and natural disasters.

Or the famine caused by wrong policies, but the growth rate of world food production exceeds the rate of population growth. The current average population nutrition level in third world countries has been greatly improved compared with 1968. This is already

The consensus of the world.

The prophecies of pessimists such as Malthus and Elridge have failed.

The development of population has its own laws. As an individual, a person cannot increase his height and physical fitness infinitely due to genetic limitations. His basic needs are a certain amount. The development of humans as population is also limited. In terms of reproductive ability, almost all

All animals and plants have the ability to reproduce infinitely, and there is no and cannot allow a species to exist alone in nature. Malthus only explains the natural surname of human beings' infinitely reproductive and ignores the social surname of human beings. Population growth will be restricted by social development, once

When the growth of human beings affects the overall interests of human society, human beings will maintain a balance between population growth and resource supply. Human beings are the rulers of the earth. The global population in the century ranged from less than 100 million at the beginning of the century to more than 6 billion at the end of the century.

, it has increased by 3 times. If you simply reason based on this multiple, by the end of the 21st century, by 18 billion and the end of the 22nd century, the population is 54 billion. In a few centuries, the earth will be full of people and there is no living space for other creatures. This is obviously not

possible.

The contemporary world population does have the problem of rapid development, and the people-to-people criticize that controlling population growth is also necessary. However, it is indeed wrong for them to accuse the third world of population growth of society as the cause of social poverty and backwardness. They ignore the

3. The reason why many countries in the world are backward in society and economy and people live in poverty is mainly due to the long-term unbalanced development of the world economy and the plunder of colonies by developed countries.

In fact, population development has its own laws. With the development of social economy and culture, production and lifestyles have become more modern. Since the 1970s, the world population growth rate has begun to decline and is expected to decline further in the future.

.Humans will more consciously control population growth, the level of social productivity will continue to improve, and human society will develop in a more scientific and healthier direction. The arguments of "people bombing" and "the end of the world is coming" are pessimistic.

Lack of scientific basis.

American environmental expert Barry Conmanner pointed out: "There is an internal process in human society that can adjust the population: the improvement of living standards will start population growth. If the living standards continue to increase to a certain level, the population will eventually stabilize.

The main reason why the population of developing China has not stabilized is that this basic condition has not been met."

With the development of the economy, people's income in various countries is increasing. According to statistics from the World Bank, the population growth rate tends to decline with the increase of income. The average population growth rate in almost all countries from 1990 to 1993 and

Their per capita income in 1993 had a tendency to be linked to low population growth rates and higher per capita income. The line in the figure shows this feature in a straight line. As income increases, population growth tends to zero. (Each

Small dots represent a country) (see picture).

Figure population growth rate and per capita income (Source: World Bank)

"We also lack historical insight on population issues. We infer global statistics and give our own explanations for this," said Schultz, an economist at the 1979 Nobel Prize in Economics.

Our explanation is that the poor breed offspring like lemmings and eventually destroy themselves. However, looking back at the socio-economic history of our own poor period, this has not happened, in today's poor countries

This has not happened during the growth," Schultz also said, "With the increase in income, parents have shown a preference for having fewer children and replacing the quantity with the quality of the children, which is unforeseen by Malthus.

Arrived."

In September 1994, Dr. Lester Brown, director of the Institute of World Observation, published an article titled "Who Will Support China" in the United States "World Observation". Dr. Brown believed in the article: On the one hand,

, With the increase in social population and the improvement of consumption structure, the demand for food will increase by 85% by 30 years. On the other hand, due to the decline in productivity, urbanization will reduce arable land and industrialization will damage the environment. By 30 years, the supply of food in China will be

According to the decrease of 1994, Dr. Brown concluded that in the case of an increase in population and arable land, the problem faced by China will be a huge food shortage. By 30 years, if the per capita food consumption level is based on

Calculated by 400 kilograms, the imported grain will reach 100 million tons, while the world's total grain exports will only be more than 200 million tons. By then, China will not only not be able to support itself, but the world will not be able to support China either.

Brown's specific analysis is: In 30 years, the population of China has increased from 100 million to 1.6 billion in 1994, and the consumption of grain has increased from 300 kilograms per capita to 400 kilograms per capita, and the total demand for grain has increased from 100 million tons.

To 100 million tons, an increase of 85%. At the same time, in 30 years, the grain planting area in China will drop from 1994 to 100 million hectares, a decrease of 47%, although the yield level can rise from 3,705 kg per hectares today to

5,700 kilograms, but the total grain output will drop from the current 100 million tons to 100 million tons, a decrease of %. This can clearly show that from 1990 to 30 years, on the one hand, the grain output will decrease by % and on the other hand, the grain demand will be

The increase of 85%, which will result in a gap of supply and demand of 100 million tons. In this way, China's domestic grain production can only meet the needs of 30 years, and the rest of the needs will be imported.

Academician of the Chinese Academy of Sciences and Researcher Li Zhensheng, who won the National Highest Science and Technology Award in 2006, said at the Boao Forum in 2005: "The result of our comparison is that Brown's inference is incorrect and does not conform to the reality of China! First, the population growth rate 13 slower than he expected. Brown expects an average annual population growth of 100,000 in the next 40 years, while my country's actual population growth in 2003 was only 7.61 million. Second, the rate of per capita farmland reduction is not as severe as Brown predicts, because Remote sensing measures my country's arable land area is more than the traditional figures published in the original release; thirdly, my country's total imports and exports of grain in 2015 have basically remained the same, with a net import volume of only 100 million jin, which is equivalent to the total consumption, and is insignificant!"

Researcher Li Zhensheng has been engaged in scientific research on wheat breeding for a long time and has developed excellent genetic varieties that are drought-resistant, dry and hot wind-resistant, and resistant to various wheat diseases. Xiaoyanmai No. 4, 5, and 6. Shan Xiaoyan No. 6.

As of 1988, the total promotion area has reached 54 million mu, and the yield of wheat increased by 3.2 billion jin. He also established a new wheat chromosome engineering breeding system, conquering the long-standing "unitvalent chromosome drift" and "chromosome number identification work that existed in the wheat utilization process.

The two major problems of excessive quantity are cultivated, and the new method of "body-deficient backcrossing method" has been used to create rapid selection and substitution lines for wheat, laying the foundation for wheat chromosome engineering breeding.

He told the world with great confidence at the Boao Forum: "Chinese people can support themselves! Now that is the case, we believe that with the correct policies of China and the development of science and technology and economy, we will definitely be able to support ourselves!"

Academician Yuan, an agricultural scientist in my country, is the world-renowned "father of hybrid rice". Hybrid rice is a world-class agricultural science and technology problem. Developed countries have entered the world earlier and invested heavily. Academician Yuan Longping uses scientific and innovative thinking and courageous exploration spirit to make hybrid The research on rice first made a breakthrough in China. With the historical mission of "keeping everyone away from hunger", he mastered a variety of key technologies through repeated trials and repeated efforts, and advanced to success step by step, realizing theories of the past Major breakthrough. This scientific research result has enabled my country to enter the world's leading level in the research and application of hybrid rice. After its promotion, it not only solved the problem of Chinese people's food, but also made outstanding contributions to world food security. Academician Yuan Longping Said: "I have three wishes now: the first is to develop super rice into the third grade super rice, and to use it on a large scale for 10 years. The second is to implement the "three-product and four-product" high-yield project, within five years, six 80 million mu of land produces grain from 80 million mu of land. The third wish is to push hybrid rice to other countries and go to the world. We are negotiating that within five or six years, we can get from the current 20,000 hectares. , it has grown to 10 million hectares, with an increase of two tons per hectare. It has contributed to the development of China's country in solving the problem of food shortage."

In August 2005, the Prime Minister of China praised during his inspection in Hunan: "The contributions made by Yuan Longping are not only beneficial to China, but also to the world." Yuan Longping used his own research to tell the world that China can not only support itself, but also to

Help the development of China to solve the problem of food shortage.

Historically, the average annual yield of Asian rice increased by % from 1954 to 196.4; the yield increase of new varieties was %, slightly higher than the population growth rate. The annual yield increase of Asian wheat hybrid varieties was % from %

Increase to %. If enough land is guaranteed to plant these new varieties and obtain the same high yield, it will ensure that the fastest-growing areas can also feed residents.

From the 1970s to the 1980s, some developed Western countries promoted high-yield cereal varieties and agricultural science and technology to parts of Asia, Africa and South America, helping these countries and regions increase grain production. Such as "Mexican wheat" and "Jasmine Rice" "etc., after these varieties and technologies were promoted in some countries, the grain output has increased significantly, which is known in history as the first "green revolution". Since the "green revolution", the growth rate of world food output has been much higher than that of the population. Growth rate. my country's hybrid rice is also an outstanding representative of the first green revolution period.

American economist Schultz pointed out: "In 1933, before the introduction of hybrid varieties, the planting area of ​​corn in the United States was 100 million acres and the output was 2.4 billion bushels. By 1987, the planting area of ​​corn was only 100 million acres, but the output reached 100 million bushels.

Compared with 1933, although the planting area decreased by 100 million acres, the output was more than three times. In addition, the decline in corn production costs, the cost of feeding livestock and poultry products decreased, the consumption surplus increased significantly, etc.

The fruits of the Green Revolution.”

The breakthrough of the "green revolution" in agriculture has comprehensively promoted the development of various important factors of modernization. Food security remains the "top priority". In the future development process of human society, it will also face water shortages and land.

A series of problems such as desertification, consolidation of cultivated land areas, etc. However, these problems arising and encountering by developing China countries will definitely be gradually solved in development.

It has been three to four million years since humans lived on the earth before they knew that the shape of the earth was an oval. This is indeed a very ridiculous thing to modern people, but it is indeed a fact. Some creatures, in fact, many creatures, are actually many creatures.

It can even be said that all creatures except humans have survived and lived on the earth for millions of years or even longer. For example, the trilobite has been sleeping on the earth for 700 million years and does not know that the earth is

What, from this point of view, is human beings so honorable.

The specific location of the sun is on the Orion spiral arm north of the Milky Way galaxy, and the volume of the sun in the solar system accounts for about 99.8%, and the volume of the sun is about 1.3 million times that of the earth. The volume of the sun is 1.3 million times that of the earth and

What is the concept? If the earth's size is as large as the sun, expanding the area of ​​the five continents and four oceans into the sun's area in proportion, perhaps until now, humans still live in different closed areas.

Perhaps Columbus has not discovered a new world until today, and the development of human history is definitely not as fast as it is now.

In addition to visiting the moon, humans have been to the nearest planet - Venus (also known as Qi Mingxing or Chang Geng Star in ancient China. This star is the third brighter celestial body except the sun and the moon. Only when the sky is dawn will the star follow.

It gradually disappeared with the rise of the sun.) It has never been there. Moreover, according to the current human exploration results, only the nine planets and their satellites in the solar system are adapted to the survival and development of organisms and humans.

Some people say that you can go to places outside the solar system to find new human settlements. This idea is very good, but from the moment it seems too difficult to achieve, it is simply a fantasy. Of course, if humans have a long period of time in the future

In time, and human science and technology are still developing and progressing, this idea can be realized by Zhou Yunna. Take the star closest to the solar system (of course, it is also to the Earth) - Centaurus A, for example. It is considered

Our neighbor star is about 4.2 light years away from us. How can humans reach such a long distance? It takes more than 4 years to run 300,000 kilometers per second, and there are almost 4 distances of more than 4 light years.

They are all in a vague space, and there is no rest in the middle. Some friends here will say that due to technical reasons, there will be errors. We will give you a discount, 2 light years, and there are also many! There are also people who always

It is easy to make a metaphor like this: It is actually wrong to say that it is as thick as it is like the stars in the sky. The stars in the sky are very sparse. Otherwise, we can really hide our heads and embrace the moon, but this is

It is very dangerous and is not conducive to the survival and development of organisms! As for reports, humans can reach Centauri through four-dimensional space in less than 100 days, but this great ambition is for humans to be present and even in the future.

It is still a paper talk for a long time. If humans need to travel farther stars, the difficulty will be even greater.

Although humans can be said to dominate everything on the earth, humans are still insignificant to the earth and even this vast universe. At present, the Milky Way that humans can measure is about 1,021 meters, which means that humans are still insignificant.

Living in the Milky Way galaxy is about 100,000 light-years wide. You can think about what the concept is 100,000 light-years. The speed of light at 300,000 kilometers per second requires 100,000 years. The distance is so far that it reminds people of

It's incredible, but this is just the Milky Way, what about the extra-river galaxy?! Isn't it bigger? According to the most authoritative data, the length of the universe that humans can observe is about 10' meters. Obviously, there are still humans who have not observed it.

What are you here? Think about it again, aren’t humans and the earth too small for this universe?

In the vast Milky Way, single stars with reading activity only account for 14 of the total number of stars, and binary or clustered stars are everywhere in the Milky Way. In these 14 single stars, planets like the sun are accompanied by planets.

There are very few stars, only one out of about 100,000 stars, and it is certain to tell the reader that the closest star to humans, Centaurus, is a binary star system (two stars orbit each other without planets), even if

Our spacecraft or shuttle can get there, but there is no place to rest.

In the vast universe, there are shining and dazzling stars that emit heat everywhere, and what about planets? Not only are there very few, but they are also very small in terms of mass and volume.

Stars are one of the most basic and important characters in the universe. Our ability to see that the universe is a universe of stars, not a universe of humans or planets. Stars are the protagonists of this universe. Of course, the previous article also said that dark energy is

The protagonist of the universe, even from the perspective of dark energy, is not an environment for human survival and development.

From the astronomical knowledge that humans have obtained so far, we know that not every star system in this universe has an earth, and an environment that adapts to human survival and development like the earth. On the contrary, almost every single one in the universe

In a star system, there is almost no earth, and there is almost no environment that adapts to human survival and development like the earth. If every star is like the sun, there is a planet with life like the earth, then humans will

Survival resources are not scarce, or the radius of human earth is very large. The larger the human beings, the less scarce the survival resources are. In fact, the universe and various celestial bodies do not appear for humans.

God gives human survival resources a limited surname, which determines or limits human survival and development. It can be said that in the vast universe, human survival resources are extremely scarce. The scarce surname of human resources has created a disaster for human beings.

The root of the human survival resources is also said that the scarcity of human survival resources is the greatest disaster for human beings and the overall root of all human disasters.

Take the solar system where humans live for example. Humans live on the earth, and their survival and development need to rely on the sun. Human survival and development cannot be separated from the sun as the star and the planet Earth that revolves around it.

Moreover, the distance between the two must be appropriate, and the state of the two must be at least relatively stable. At the same time, the earth also needs to have appropriate temperature, gravity, moisture, sufficient sunlight and prevent external radiation from harming the human atmosphere.

So. We can imagine that if life exists in a universe where humans live in a three-dimensional space and one-dimensional time (in fact, these two are closely linked and inseparable wholes) it must be like

Our sun has the same relationship with the earth. First, there must be a star that emits light and heat, and secondly, there must be a planet that rotates around it. Finally, the planet's environment must also have the conditions for living and development. Unfortunately, about 10

Only one star like the sun in ten thousand stars. What is the concept of one hundred thousand? Only one star like the sun can move alone and be accompanied by planets in ten thousand stars. This probability is more than buying a lottery ticket.

Winning the prize is even lower. What makes people even more disappointing is that the distance between stars is too far. The average distance between stars in the Milky Way is about 6-7 light years. Therefore, it can be said that in the universe, human survival and development

Resources are extremely scarce.

"At the end of the century, the United States conducted an experiment code-named "Biosphere 2" to study whether humans can live in sealed artificial ecosystems for a long time. An experiment was built with a steel frame glass seal covering an area of ​​more than 13,000 square meters, and it was carefully designed inside.

The arrangement is made of woods, grasslands, pastures and 'artificial oceans' to feed pigs, chickens and other animals. The entire device costs more than 200 million US dollars. In 1993, eight scientists entered it and planned to conduct scientific research while farming.

It is planned that this ecosystem should maintain ecological balance, the oxygen content can remain unchanged, and food can be self-sufficiency. Scientists will live in this sealed body for two years. But more than a year later, the oxygen content in the sealed body has dropped from 21% to 14%.

Moreover, the grain was poor, so people had to eat the crops. In this case, people were forced to withdraw early, and the "Biosphere 2" experiment failed. "The failure of this experiment showed that humans could not survive for a long time without the earth's environment.

At present, although humans have established some space stations and left human footprints on the moon, this is still a great distance from the environment where humans live and live for a long time. (To be continued.)
