How many people can the earth bear?

The ultimate population is shocked! The earth can also carry 7.7 billion people in "26 billion times";

Former Director @Just Ultimate Research Institute 2020-06- 10

"Brain in a vat" is an ideological experiment put forward by hilary putnam in his book Reason, Truth and History in 198 1.

The details are as follows: a person (you can assume yourself) was operated on by an evil scientist, and his brain was cut off from his body and put into a jar with nutrient solution to keep his brain alive. The nerve endings of the brain are connected to the computer, and the computer sends information to the brain according to the program to keep him completely normal. For him, it seems that people, things and the sky still exist, and his actions and physical feelings can be input. This brain can also be input or intercepted (the memory of brain surgery is intercepted, and then the various environments and daily life that he may experience are input). He can even be coded and' feel' that he is reading an interesting and absurd text here. ";

His question at that time was: How do you ensure that you live in the "real world"?

After 19 years, the 2000 Nobel Prize in Medicine was awarded to arvid carlsson, MD, who invented a nutrient solution to support the thought experiment of "brain in a jar". This nutrient solution is named "Dopamine". The doctor's scientific experiments have proved that this substance "Dopamine" is the core information transmitter in the human brain and is related to all addiction and happiness.

Around 2000, the Warner Bros.-style sci-fi movie The Matrix trilogy appeared, and in the original "brain in a jar" thought experiment, a (dystopian) world view was constructed. In this world view, intelligent hackers ruled the human world, and people were linked to machines to live and controlled by machine hackers.

The hero, in the dystopian world, plays the role of a new hacker. He leads a few free-will human beings and finally saves the world.

As for the science fiction film and television industry, there are many brain supplements in the later period-"brain in a vat", but they are mainly concentrated in places where science fiction literature is relatively mature, such as Europe, America and Japan, so I won't list them here.

Now, Musk, known as the first modern brain of American entrepreneurs, announced the establishment of Neuralink (Neural Network Company) on 20 16, developing what Musk called "neural lace" technology, implanting tiny electrodes in the human brain, which will be used to upload and download people's thoughts one day, so that people can break away from the physiological limitations of carbon-based life, enter the silicon-based world, and realize the permanence of human consciousness. In the early days, individuals contributed 65438+.

Recently, according to the official disclosure of Neuralink, its brain-computer interface equipment is expected to be tested on humans this year, which means that humans are farther away from uploading and downloading memories.

As for "Chen Tianjiao", the richest man in China before 2004, who has long been forgotten, and his wife, Rosandi, after selling a lot of original Shanda assets, they established the Chen Tianjiao Qian Qian Brain Science Research Institute for short.

Of course, after consulting a lot of information about Chen Tianjiao, I found his two brain science experiments and two conclusions very thought-provoking.

A: The world is virtual. B: Humans are just chemical robots.

The following is a 1 hour brain science documentary "Opening the Door of Thought" shot by TCCI Research Institute (if you are not interested, you can skip it and read our conclusion quickly ~ ~).

Of course, not long ago in China, a research on "accurately deleting specific memories" by the team of Peking University was published in the sub-journal of Science. The researchers used gene editing technology to accurately delete specific memories in the brains of experimental mice. But despite this, it still stays more in the field of academic theory and laboratory, but Musk is different. He is a doer.

Speaking of China, of course, the book Malthus Revolution and the End of Moderate Population, published by China Environmental Science Press on 20 13, was written by former Professor Huarong, trying to subvert the theoretical trap of Malthus Trap in Human Demography written by British Malthus 200 years ago.

Book Review: To tell the truth, when I read this book myself, I felt like "Professor Huarong". His initial intention is excellent, and his research direction is also excellent, but he pays too much attention to historical elements and hardly considers futuristic elements. One of the deep-seated global problems is that I seriously doubt that "more than 200 years ago, after fully planning the global population expansion, the British invited experts like Malthus to beautify the macro rationality of their country's population development." Because there are countless examples of fraud in history, and I am a conspiracy theory. "

As for the definition of "Malthusian trap" in classical demography.

Population growth follows geometric progression, while living resources only follow arithmetic progression. The extra population will always be eliminated in some way, and the population cannot exceed the corresponding level of agricultural development. This theory is called the Malthusian trap.

It sounds reasonable, but the original professor summed it up brilliantly with the word "moderate population". In my opinion, the British conspiracy is that none of you will develop the population, but we will develop it in secret. Results At present, 65.438 billion people are learning English, and 46.5438 billion people are white, accounting for 54% of the largest race in the world. No one suspects that it is burning, killing, looting and rape.

Of course, there are also many people who think that the human population growth has been "completely surplus" or crazy, and hope that the world population growth will not be so fast, including Japan's aging population, serious single rate, and people do not want to live in cities below the third tier. Everyone is crowded in the metropolis Tokyo and several important cities-cities below the third line, and no one delivers houses.

As for the first-tier cities now, when I was in Shanghai, I roughly calculated how many people can be accommodated on the beach. I think it is entirely possible to accommodate 200-500 million people, but it will put forward higher requirements for modern urban planning and construction, social coordination and people's cognitive concepts. But to be honest, I have searched all over the world for so-called poor knowledge, and I have never seen anything that satisfies me. I can answer "what will happen to the ultimate urban civilization of mankind?" What will happen to the population? What will business be like? What will happen to the human rights of men and women? I have seen countless people actively and passively believe in a so-called low IQ life planning, career pursuit and anti-intellectual sex concept completely controlled by hormones. I always ask myself, what is the use of learning knowledge?

Knowledge does not need planning, the overall layout of life, strategic long-term thinking, domino development. Knowledge can't make a person, like a painter, first lay out the whole aesthetics, then fill in some of them little by little, and finally draw a beautiful picture of life and realize the most meaningful meaning of life. What can knowledge do? (from a philosophical point of view)

Then, then, listen to our "ultimate problem research institute" In today's "great uncertainty" and near "global confusion" of the global financial crisis and epidemic spread in 2020, how should we study and answer such a super-large topic as how the final population of mankind develops?

The "ultimate population problem" also raises many questions:

How many human beings can the maximum limit of the earth accommodate? What if the accommodation is the most abnormal? How much food did people need then? How much accommodation do you need? What about urban planning? What will be the limit of the relationship between man and nature?

Of course, what "blanks" have not been considered by mathematicians, science fiction writers, politicians, capitalists, entrepreneurs, sociologists and economists all over the world, including ecology, educators, brain science experts and various engineers? Or how to prove that these so-called experts are "conservatives"? People with vested interests do not want their civilization to progress faster, so that a small number of people can slowly enjoy the pleasure of riding t a on their heads.

If we define the study of our ultimate problem as expanding people's cognition and thinking through the extreme pursuit of "ultimate radicalism", establishing a brand-new socialized "strategic development" joint force, accelerating the faster progress of our civilization, looking for opportunities for innovation, and creating more opportunities for people to maximize their personal destiny, just like the earth is saturated, we explore interstellar colonies to expand the opportunities for individuals to change their destiny, and will not affect the "almost zero-sum game" of vested interests.

Come on, let's answer the ultimate population question. ...

1. The total land and sea area on the earth is about 5 1 100 million square kilometers, of which the sea area is about 36 1 100 million square kilometers, accounting for 7 1% of the global total area, and the land area is about1400 million square kilometers, accounting for 29% of the global total area.

Because1km2 =100000m2 (1ten thousand m2). Then the land area of the mainland is 1490,000 square kilometers = 149 trillion square meters. Since the general formula of China people's surface area is S=0.006 1× height +0.0 124× weight -0.0099, we take the formula of standard yellow race people's surface area as 170cm, 70kg. Then divide 149 trillion square meters by 1.905 square meters =78.2 15 trillion population.

That is to say, if the standard China people (height 170cm, weight 70kg) with a surface area of 1.905m2 all cover 29% of the earth's land, then the earth's land surface area can accommodate 78.2 15 trillion yellow people, that is, 782 15 billion people. -It is 1.0 1.57 times that of the 7.7 billion people in 2020. In other words, today's population of 7.7 billion will be expanded by 1000 times, covering 29% of the whole country.

(And it's only two-dimensional like paper, comparing the earth to a piece of paper, regardless of depth, only considering the population coverage data of 100% plane, excluding the spatial expansion of office buildings, offices and buildings. )

Two: the height limit of the population living on the earth. (20 kilometers below the ozone layer)

Note: The bird with the highest natural flight of human beings will fly to a height of about1.65,438+0,000m, but human civil aircraft usually reach the troposphere 8 8- 10/0km as shown in the figure. The fresh air on the aircraft comes from the air compressor provided by the aircraft to compress the thin air, so as to provide passengers with breathing during the flight.

Supersonic aircraft can reach an altitude of 20,000-40,000 meters through the ozone layer, but the pilot's breath also comes from the fresh air stored in advance by the air compressor.

So we set the maximum habitable height of normal human beings at the lowest point of the ozone layer of 20 kilometers.

Third: the manned submersible can dive to 109 16 meters. 1960 after diving, there was no Trieste submersible called. At present, the dive depth of China Jiaolong is 7062 meters. We set the limit depth of human habitation at 6000 meters.

Four: The picture below shows the top ten highest buildings in the world. What we want to further confirm is that the human world in 2020, in a sense, only lives on a "two-dimensional" paper, which is very similar to the huge ant civilization developed on paper. Ultimate perspective

Five: the map of the earth structure. The use of this picture means that we have not considered the situation that human beings live in the "mantle and core" under more exaggerated circumstances. Now the real estate developers are probably going to collapse.

Six: It is also clear here that we do not consider the infinite expansion of the earth's outer space to calculate the earth's resource limit of our final population. (The picture below shows the future space city works designed by astronauts. )

Seven: If it is calculated that 7.7 billion people in the world need to expand by more than 10000 times to cover all land surface areas of the earth. By calculating the depth of 2-6 non-planar habitable spaces on the earth, the total number of habitable humans on the earth is calculated.

Let's take an example: the population of 78 trillion just calculated is only equivalent to an A4 paper with a super population on it, covering 29% of the land area of the earth. Then a sheet piling, a layer of paper, with a height of 20,000 meters, plus the habitable area of human beings in a three-dimensional space of 206,000 meters and the animals sinking into the sea of 6,000 meters.

Because we took the height of a standard yellow race 1.7 meters. So if you divide 206,000m by1.7m =121176th floor.

In other words, we need to use 78 trillion yellow people painted on 29% of the earth's land area and multiply it by 12 1 176 yellow people printed in 3D.

Then the total human habitable population on the earth will reach: 945 1.728 trillion. We divide it by the population of 7.7 billion in the world today = 65.438+22.7 million times.

That is to say, on the land occupying 29% of the earth's area, assuming that everyone is 170 cm tall and weighs 70 kg, he can fly up to about 20 km and swim up and down to 6,000 m at the lowest, if human beings are fully developed on 29% of the land (that is, the upper and lower layers of arhats are abandoned), then the development limit of the total human population still needs to be 77% in the existing world. Only after 65.438+0.227 billion times of crazy expansion, reaching 945.10.728 trillion, can the total population reach its limit.

And this has not counted the development of ocean area 100%, which accounts for 7 1% of the earth's area. Just now we only calculated 29% of the land area.

So what is the final total population of the super earth?

7 1%/29%=2.4483.

2.4483*945 1728 trillion = 23140665000 billion population.

If we divide by the world population of 7.7 billion in 2020 today, we will get 3005280000 times.

In other words, if human civilization wants to fill the habitable space of the earth 100% (excluding the mantle, bottom shell and ozone layer), it needs to develop a population of 3005280000 times on the basis of the global population of 7.7 billion.

Eight: it's not over yet ~ ~

Absolute population evolution of "brain in a vat"-as long as you take the brain and soak it in dopamine solution, you will be a human being. How many people does the earth need to be saturated?

The figure below is a schematic diagram of the brain capacity of some species on the earth.

The conclusion of brain science is that the bigger the brain, the smarter it is, and the smaller the brain.

The human brain seems to be naturally "gentle"

So, what does the human brain contain? What is the surface area?

Professional data: The human brain is composed of about 1400 billion cells, weighing about 1400 grams, and the thickness of the cerebral cortex is about 2-3 mm, with a total area of about 2,200 square centimeters. It is estimated that about/kloc-0 per million brain cells die every day (the more brain cells are not used). The main component of the human brain is blood, accounting for 80%. Although the brain only accounts for 2% of human body weight, its oxygen consumption accounts for 25% of the whole body oxygen consumption, and blood flow accounts for 15% of cardiac output. The blood flowing through the brain is 2000 liters a day. If the energy consumed by the brain is expressed by electric power, it is equivalent to about 25 watts.

Because we have always adopted the surface area formula of standard yellow race: height 170cm, weight 70kg, and the surface area formula of standard yellow race = 0.0061*170+0.124 * 70 =1.905. ..

Because 1 m2 = 10000 cm2.

So: 19050 cm2 (whole human body) /2200 m2 (brain) =8.66.

That is to say, 866 * 2310.40665 billion population = 20039810.589 billion population.

If you divide by the total population of 7.7 billion in the world today.

That's 26025724800 times.

The final super big conclusion:

Conclusion 1: if the ultimate pursuit of human society is that everyone lives in dopamine solution in the brain in a jar, then according to the area of the earth and the rough natural environment. 2 1 century human society has a population of 7.7 billion. To cover the whole earth space and realize a productive society in which everyone is in a jar, it has to expand and develop 26 billion times crazily.

Conclusion 2: If human society does not follow the brain in a jar algorithm, and follows a standard yellow person, with a height of 1.7m, a weight of 70kg and a surface area of 1.905 m2, then the whole earth will be full of yellow people, who will be able to breathe and sleep regularly. Then it is necessary to develop a population of 300,528,000 times (about 3 billion times) on the basis of 7.7 billion people.

At the end, write a poem for everyone.

On the poem "The Ultimate Population"

On population, the British wrote "On Population" 200 years ago.

I suspect that this is already a masterpiece of the British to beautify the white people.

Because everyone knows what happened afterwards.

It only took white people less than 500 years.

From a small race, it has become the largest race of mankind.

And no one has ever doubted the dirty history of TA's rise.

A few years ago, an old professor at china environmental science Research Institute.

He wrote a work that defeated the British "population principle" 200 years ago.

What I don't know is, what does Guo Jia mean?

But now that I think about it, I beat someone 200 years ago.

What's so rare?

The world is changing rapidly.

In 200 years, the human population has increased from less than 500 million to 7.7 billion.

What about World War I and World War II?

What about the first or second feminist movement?

Many people are worried about "overpopulation"

Yes, I'm also very worried about overpopulation.

But I calculated it carefully today.

Under the guidance of the brilliant research direction of the institute of ultimate problems

Even China's science fiction master Liu.

The two projects will drive only 5 billion people to Australia.

So what if we go to the Colosseum in Rome?

What about the capitalist paradise?

Have we applied the basic knowledge of geography and space science?

And applied 198 1 year "brain in a jar" thought experiment.

Including the Nobel Prize in 2000.

The invented "dopamine" super brain nutrient solution

Useful, classic sci-fi movies

Matrix trilogy

Because there is not enough time, there are fewer movies to find.

There are many aspects, but none of them can answer the final population question.

For overview only)

Of course, we also saw it.

20 16 American entrepreneur star musk

The progress of the established human brain interface company

Including Chen Tianjiao, director of TCCI Institute of Shanda University, and his wife.

They are all committed to

Using scientific and technological means to achieve a major breakthrough in human brain science.

But unfortunately, there is no strategy involving the "ultimate crowd".

We are the only people here who knock the theme to death.

Perhaps, some people will feel meaningless when they see it.

But we believe

This "ultimate population" project

But anyone with ambition and pursuit

Entrepreneurs, including future children, have seen it.

TA people can definitely learn from this topic

Smell, unlimited business opportunities for mankind are growing.

Not seen by the world, superficial

Politics, economy and ecology

Blinded by literature and poor education and technology

See a brand-new big blue ocean ...

What blue ocean?

In the future, mankind will expand on a large scale.

The single rate in today's world and the low birth rate in developed countries.

Japan looks aging, unmarried and infertile.

No one wants to buy cabbage prices for real estate in cities below the third tier in Japan.

Is that all?

As long as artificial uterus technology

Gene editing technology

Egg sperm freezing

Moreover, the modern country has completely taken over the scientific reproduction of children.

For millions of years, traditional parents and children

And the disappearance of the so-called "raising children to prevent old age"

But adopt a more advanced financial and insurance system.

Then, everyone can fall in love and die.

Today, regardless of sex,

It also eliminated "Martian immigrants" and "space cities"

Including the creation of urban elements in the crust and mantle.

Let the surface of the earth

Calculation method of eaves fill

We have come to such an amazing conclusion.

7.7 billion people

Need to develop 26 billion times.

Realize the utopia of everyone's brain in a jar

7.7 billion people

It needs to be developed 3 billion times.

Realize that everyone flies over the eaves and walks over the wall, filling the small three-dimensional space of the earth.

This makes me more convinced.

The next model of the human world

The population continues to increase exponentially.

If the west does not make the population scientific and technological and innovate new ethics,

Then there is no successor, and it will inevitably decline.

Just the polarization of the world.

Or * * * materialism, basic necessities of life.

How will the game be played?

I know I will definitely continue to rewrite many rules of the game.

We entrepreneurs also need to be involved.

Share the bonus with knowledge, ultimate wisdom and diligence.

Finally, we have one more thing to say.

After all, human power is limited.

The only meaning of learning knowledge is to be able to make strategies.

By thinking about the ultimate question

Discover many big blue oceans in the future world.

What's more, in the era of digital economy

We can also use the ultimate digital strategic thinking
