The second volume of this book is also over, which is both a summary and a testimonial.

The first volume deals with controlled nuclear fusion and potential thermal crises, and changes in the social system caused by controlled fusion as a result of changes in the political situation of various countries, the development of science and technology, and the alleviation of resource and energy problems.

The second volume writes about the Muba civilization of the producers, some questions about the nature of intelligent life, questions of faith, and blue people, explaining part of the interstellar background, and explaining my understanding and views on the lack of aliens.

A lot of the content is not written in detail, but the complete framework is also explained, and they are scattered in each chapter of the text, which may be a sentence or a narration, which needs to be carefully read.

Online article, talking to readers about reading books carefully, I'm afraid I'm the first one in these years, maybe that's why I hit the street.

In the second week of its release, the outline of this book was overhauled, and the content of the second volume, that is, the Martian Muba civilization, the blue people, and the interstellar background are all plots after 600,000 words.

The original outline was to finish the plot of the follow-up to the heat crisis, let the protagonist pretend to be forced on the earth, establish a relatively complete scientific and technological system, and explain the background of the political situation of various countries clearly......

I'm going to finish writing this, and then the plot will develop into outer space.

However, it may be that I wrote too realistically, which led to the emergence of uncontrollable factors, and these plots were cut.

During that time, due to the overhaul of the outline, the mood was very bad and the plot was also very chaotic.

Originally, the relationship between the three heroines will not be determined until the end, and the protagonist will choose one of them, instead of cutting off the emotional line like the current 152 chapters.

There is no emotional line, which is a taboo in online articles, and the subscription dropped by one-third at that time, and a large part of female readers and some readers who want to read the emotional line have abandoned the book.

Then there are chapters 158 and 159 where the blue man appears, and the style of the book changes from the earth city to the alien world, and many readers here abandon the book.

Subscriptions plummeted, from nearly 900 to less than 300.

300 subscriptions, I code a chapter of 2000 words for almost two hours, 2000 words a chapter of the income is only about 12 yuan, an hour 6 yuan.

In addition, I thought about the heat crisis for a long time, and I checked a lot of information before I could write the perfect plot, which was a big blow to me.

At that time, my mentality was really a bit broken, and I thought about eunuchs cutting books more than once.

But at the time, I thought that it would be nice to finish writing about the Martian Shepherds, my thoughts on the Fermi paradox, and my understanding of the Great Filter.

Looking at the Fermi paradox from the perspective of the development of the universe:

Regardless of the fact that the universe was born 13.8 billion years ago, the earth is really the first planet to have life.

It's just that life on Earth evolved very slowly, and it took 3.8 billion years from the emergence of life to the emergence of humans.

This means that there are many intelligent and civilized beings in the universe that evolved earlier than humans, and most of them may still be in the process of gestation.

So there should be extraterrestrial life in the universe, but either it hasn't left the planet like humans, or it's vast and sparsely populated, so we don't see it.

From the perspective of scientific and technological development and physical rules, Fermi's refutation is as follows:

The attenuation phenomenon of electromagnetic wave communication, in the interstellar space, which is often light-year, human beings use the maximum power to transmit electromagnetic wave communication to Proxima Centauri, and under the premise of not using a relay station, this electromagnetic wave communication will become a clutter after a distance of 4 light years.

Maybe Tianwan Four, maybe the Aquila Galaxy, and even Proxima Centauri and other galaxies have the same civilization as humans, and everyone is desperately shouting into outer space, looking for other civilizations other than themselves.

It's just that the electromagnetic wave communication sent by everyone, after spanning such a long distance, contains regular information that has long been lost, so we can't hear it, we can't see aliens, and aliens can't hear it, and we humans can't see it.

And the more advanced civilizations, the civilizations that can carry out interstellar voyages, electromagnetic waves, a communication method with many drawbacks, are still eliminated.

They may be communicating with gravitational waves, or they may be communicating with tachyons, but either way, it's beyond human technology, and even if they speak in your ear, you can't hear it.

As for searching with telescope arrays, only planet-level objects will be seen light years away.

Kilometer or 10 kilometer warships, in the image scanned by human telescopes, do not have the size of a single pixel, which also leads to the inability of human beings to see the activities of advanced civilizations.

It is even very possible that advanced civilizations have not used working engines, but used curvature navigation or other space-time engines to travel faster than light by changing the structure of space-time.

Changing the structure of space-time and space to sail is invisible to humans flying outside the earth, after all, human gravitational wave research is just in its infancy.

The Fermi paradox from the perspective of the big filter:

The Great Filter is a view that was put forward decades ago, and according to this view, corresponding institutional contradictions, obstacles to scientific and technological development, and civilizational potential were born.

The viewpoint of institutional contradiction points out that the contradictions between various social classes are always on the rise, and that in the modern era when civilization has developed to the present, and in modern times when nuclear weapons can bathe the earth, it is very likely that the contradictions between various social classes and countries will erupt until one day, and thus destroy themselves.

Not to mention that aliens are different from us humans, aliens are also intelligent beings, and with wisdom there must be desires, classes, and contradictions.

Without desire, without class, without contradictions, it is impossible to stand out in natural evolution, destined to be eliminated by nature, and there is no chance of developing civilization.

Therefore, except for the collective intelligent life and the producer intelligent life, the contradiction in this regard is not so strong, and the rest of the civilizations developed by individual life will have classes and social contradictions.

They are likely to perish in self-consumption and in the outbreak of war because of the existence of social contradictions.

It may also be like the decline of the modern fertility rate and the inhibition of reproduction by the shepherds in the text, the social survival pressure caused by institutional problems, and the inhibition of reproduction by organisms seeking advantages and avoiding disadvantages, will lead to the demise of civilization.

The problem of scientific and technological barriers from the perspective of large filters, everyone should have seen a lot of science fiction like this.

Controlled nuclear fusion of energy, engine technology for interstellar navigation, light-speed barriers, life support in outer space, biological lifespan, etc., are all considered to be a point of view of the Great Filter.

Civilization potential, in fact, can be attributed to the lifespan of civilization members.

Newton once said: I succeed because I stand on the shoulders of giants.

But with the development of science and technology to this day, this giant has been stacked into the sky like a stack of arhats, and it takes more than one-third of a person's life to climb from the ground to the shoulders of this giant.

With the continuous advancement of science and technology, this climb to the shoulders, and the time to learn knowledge will become longer and longer.

Perhaps a hundred years later, when human beings have completed the accumulation of knowledge and can conduct research on topics, they will be 40 years old at that time.

In other words, if the lifespan of the members of the civilization does not increase, the potential of this civilization will stop there.

The Fermi paradox from the perspective of the humanity of intelligent life:

This is the theme of the book, and it is also a possibility that the praying mantis himself came up with, extending from the conjecture of rule technology.

The universe is so big that the latest research suggests that the universe may have 2 trillion galaxies like the Milky Way.

In such a vast cosmic space, there will definitely be civilizations that break through the Great Filter and develop into advanced interstellar civilizations.

There is a winner-takes-all phenomenon in society, which is known as the Matthew effect.

In fact, the universe can also be seen as a huge society, and every civilization is a member of this big society.

Just as there are no two intelligent beings who are exactly the same, even if the material composition of the two people is completely reproduced with high technology, their thoughts and thinking will be different.

Intelligent life is not exactly the same, and civilizations are not exactly the same, they are all unique.

Since there is uniqueness, there must be some value in it.

For advanced civilizations, the study of intelligent life and civilization may be able to gain some inspiration and benefits.

The difference between civilizations, the currency of human beings is not accessible in alien civilizations, and the currency of aliens will not be recognized by human beings.

And the resources and materials, out of the planet, the entire galaxy and the entire river system are dug with you.

In the vast and sparsely populated universe, if you dig up a few planets to extract the energy of a few stars, no one will care about you, so until the number of civilizations reaches a certain level, the value of material resources will not be very high.

However, although civilizations are different, currencies are not universal, and resource value is not high, there is still an absolute hard currency between interstellar civilizations, that is, scientific and technological data information.

If this advanced civilization wants to get more research materials, the easiest and most effective way for them is to let other civilizations in the universe work for themselves.

Use technology that is relatively low-level to them and will not threaten them as a reward and bait, tempting other civilizations in the universe to harvest civilization information and then exchange it.

In this way, this advanced civilization has a continuous source of research materials, and for them, what they pay is only some scientific and technological data information that can be copied countless times, which has become outdated.

People die for money, birds die for food, and the weak follow the rules set by the strong.

I think there may be such a high-level civilization in a corner of the universe, who are studying civilization, studying the nature of wisdom, and in order to obtain more research materials, they have launched such a dark feast of civilization harvesting......

The specific situation, why the advanced civilization conducts such a civilization study, etc., will be revealed later in this book, which is also the theme of the next or even the next two volumes.

In the process, you may see all kinds of low-level and high-level civilizations, see some strange life, see the appearance of dying civilizations, see the praying mantis sail on curvature, and conjectures about higher technology.

These contents are almost extended from the existing scientific theories of science and technology, and the praying mantis will try its best to ensure that little bit of hardcore, and even the existence of the system will have a reasonable science fiction explanation.

Of course, the length of this book may not be very long, not millions of words, and it is estimated that it will be over a million, although my outline can support more than 3 million pages.

I'm updating the code word now.,That is, I rely on my hobby to stick to it.。

300 subscriptions, I have to spend three or four hours a day on code word updates, and then I get more than 600 yuan a month.

600 yuan a month in Pengcheng, let alone eating instant noodles, I can't even afford to live in the worst house.

So reality is reality after all.

Now because of the hobby of writing and writing, the family has been urging marriage, one day the praying mantis is off the list, if the subscription results of the book have not improved, the book has no results, and there is no need to insist on writing if the income is not proportional to the pay.

After all, I also want to live, and in the face of life, hobbies must stand aside after all.

At the end of the volume, I would like to thank those readers who have been supporting and even rewarding, quite a lot, there are 300 people, and some of them have supported since the last book, thank you for your support and give me motivation.

Thank you from the bottom of my heart.

In addition, book friends who look at pirated editions, if you can, come and see the genuine version, it's only a few dollars a month, a subscription is nothing to the gods, but for the street, that's the motivation to persevere.
