Dear my reader, unfortunately, I have to write this warning: everything stated in this book is fiction. Attention: the author is not responsible for any consequences from reading, as well as for your individual perception according to your worldview.

And now off the record: my dear reader, in this work, as in all my previous ones, you will find solid science fiction, plenty of historical facts, an alternative view of known history, cold analysis, as well as humor and satire. It's your right to take each of these definitions in your own way.

The human hearing organs can distinguish between 16,000 and 20,000 hertz. Below that threshold is infrasound. Above that, ultrasound. For example, at a frequency of 7 to 13 hertz – a natural wave of fear emitted by typhoons, earthquakes, volcanic eruptions – sounds that encourage all living things to leave the centers of natural disasters. Now, think about it: people didn't know this once, but they were influenced. That is, something influenced them, made them act, made them afraid, but the reason was unknown to them and, accordingly, was attributed to the will of some mysterious powerful forces. So the message from the past, which has reached us in the form of a word, including the one that was "in the beginning", influences our consciousness, prompting it to make this or that decision, often with unknown consequences. Believing in the Creator, we hope for good in the content of this message, but in the message itself there is a prediction of tragedy expressed in a mythical phenomenon called "the end of the world". And supposedly this phenomenon should happen as a result of the actions of people. Only it is unknown whether there is a method to avoid this phenomenon or it should happen naturally, because the one who should allow this phenomenon to happen was created by the Creator Himself. Perhaps it is some method of transforming the object of creation, that is us. Even if you hold to a strictly empirical worldview, you must agree: without natural cataclysms, i.e. changes in nature, man would not have come into existence. If you adhere to a religious worldview, you will consider even such a remote in time event as the Cambrian explosion ,1 as an act of God, and if you adhere to a scientific worldview – as a natural natural process.

Now imagine a situation, when an unpleasant event should happen to you (or remember when it happened), and possibly a tragic one, which you, naturally, would like to avoid. Simulate the possibility of going back in time and, knowing the consequences, take measures to prevent this event, i.e. behave correctly. In ordinary life we cannot go back, but we try not to repeat similar mistakes, knowing the consequences. Both the instinct of self-preservation and intelligent decision-making are based on this. It gives experience, unless, of course, the event ended your life or the life of all mankind.

Accordingly, if there is an event in the past that killed many people, that is, it was massively tragic, and repeated many times, then people cannot either determine or change the root cause of that impact. In any case, the global consequence of that impact has not yet occurred, for as yet our reasoning about what it is is still a fact.

Now, based on this understanding, let us ask ourselves the question – is not the religious teaching, the essence of which is to preserve our life (given to us, we think, by the one who created us), the root cause, which, protecting us from death, inspires us not to be afraid of this death, because it itself exhorts us to the possibility of being in a better world – in paradise. And most importantly – and more tragically – it predicts the end of the world, promising a new and better one. Based on this, let us answer frankly to ourselves: is not our belief in what is written above an incentive to allow the use of weapons of mass destruction? Although we know about its ability to destroy mankind many times over. The very illogic of creating nuclear weapons in such quantities speaks of our faith in miraculous salvation or in the possibility of life after death.

And now let's talk about an event which, strange as it may seem, according to the previous logical series, is either natural, or possible, or at least occurred in other worlds. Here I must stipulate: for all my empirical method of judgment, I adhere to the biblical statement about other worlds, that is, I believe that they are real. Agree, the belief that there are other worlds is much stronger than the doubt in their existence. Proceeding from this attitude and from the logical conclusion about the influence of religious writings on us, the contradiction "if they exist, why don't we hear them" comes across the hypothesis "we don't hear them because at a certain stage civilizations destroy themselves for some paradoxical mysterious reason". And this reason, though not confirmed in reality, is considered to be logically natural, a natural process of intelligence development. That is, civilizations destroy themselves, as intelligence itself creates what will destroy it. And the reason is banal, it is in the very essence of existence of the cognitive system of a thinking being. The essence is in the properties or, more precisely, in the nature of intelligence, as such a function of the brain – in the very method of its development. It is expressed in the following: intelligence appears, exists and develops only if it gains experience by trial and error. But in the process of development, sooner or later one of these "trials and errors" becomes a global catastrophe. Of course, the scale of globality is proportional to the level of intelligence development – simply put, it is equal to the method of self-destruction he himself has invented. In the process of development, the levels of his inventions, i.e. his own work, are equal to the scale of destruction of the carriers of this intelligence, i.e. people, with the help of these inventions. What the intellect invented was not originally created to destroy itself, but do not forget about the method of trial and error – more precisely, about what it lives at the expense of. Such is the unity and struggle of opposites. The final chord may come when intelligence develops civilization to the point where it invents the technology with which to potentially find and communicate with other worlds. Since even by means of radio waves, the speed of which is equal to the speed of light (300 thousand kilometers per second), we need about two and a half million years to communicate with the nearest galaxy, we most likely use a method that does not fit into the laws of physics – communication by the method of quantum entangled pairs2 . And since the "life" of intelligence, or rather, its food is contained in the method of finding the right solution through trial and error, eventually one of them becomes global. Such is the paradox.
