In today's regular meeting, Zhang Hong, the head of the institute, counted today's observation data, and then said: "I have a new idea about the phenomenon of abnormal disappearance of stars. I can't find any evidence for my idea, so I'm not responsible for the authenticity of the idea. I'm just bringing it up in the hope that it can give you a little inspiration. ”

"The focus of anomalous disappearances is all about their distances, and everyone is trying to find something above the distance, using dust clouds or gravitational lensing, spatial mechanisms, etc., but let's not forget that distance also means time. Those stars that disappeared abnormally all existed in the early days of the universe billions of years ago, and the cosmic environment at that time may not be the same as the current cosmic environment. Therefore, you may be looking for some possible explanations from the aspect of time. ”

The principle of "distance is the ratio of time to one" that is followed by the change of the cosmic environment to explain the disappearance of stars is also barely explained, so everyone began to discuss Zhang Hong's new idea.

This idea is only a general directional proposal, and it is very difficult to verify it, but it is certainly not a new direction to prove. But Zhao Lan felt that this explanation was untenable. Because there is one most obvious loophole that cannot be answered: if the disappearance of such a star anomaly is caused by the difference in the cosmic environment, then ...... Why has this phenomenon never been discovered before? Why has this phenomenon not been seen in high concentration until now?

Any attempt to explain such phenomena in terms of "necessity" will be countered by this logic.

"Director Zhang, I don't agree with your point of view." Zhao Lan stood up and said, "I think...... The disappearance of the astral anomaly is not an inevitable event, that is, it is not actually caused by some mechanism that will inevitably occur in the evolution of the universe. Whether it's nebula occlusion, gravitational lensing, or the cosmic environment you're proposing now, I can use a logic to refute it: if that's the case, then why haven't we ever found this phenomenon before? Why has it been that we have never found a star that has completely disappeared due to dust obscuration, nor have we found a star that has disappeared due to changes in the cosmic environment? ”

Zhao Lan's words silenced all the colleagues who attended the regular meeting. Because everyone found that what Zhao Lan said seemed to be very right. It seems that this is indeed the case.

"I think...... The anomalous disappearance of the stars is not due to some "inevitable" reason, but to chance. Zhao Lan continued: "Only a fortuitous phenomenon can explain this event, and can explain the logical loophole of "why we have never found it before". I think...... The direction of our work in the future. There should be a move towards the search for contingencies. ”

Zhang Hong was silent for a moment, and then said slowly: "Is it an accident...... Zhao Lan, you seem to be implying that this incident was deliberately committed by certain forces...... You seem to be hinting at the existence of aliens with superpowers. ”

Zhang Hong's words seem to be a bit headless and tailless, but just like Zhang Hong can easily understand Zhao Lan's words, Zhao Lan can also understand Zhang Hong's words clearly and clearly.

A star was formed. Then after a long time, it had different endings due to the difference in mass, or it gently turned into a white dwarf, or it turned into a neutron star after the supernova exploded, or it turned into a black hole after the explosion of the extreme supernova...... These are inevitable events, and they follow the laws of physics.

Inevitable events are repeatable and verifiable. For example, something like the explosion of a star is not only once in the universe. It has appeared in the past, and it will be found in the future as well. It can be observed and then investigated. Serendipitous events are different. Chance events are arbitrary, and they may be repeated within the scope of the universe, but at least relative to the human civilization as a whole. It has no or only very low frequency repeatability.

Suppose there is a physical law in the universe that causes the universe to flicker once every 10,000 years, and assuming that the lifespan of human civilization is less than 10,000 years, then in the entire life cycle of human civilization, human beings can only see this kind of flickering once, and this flickering will only occur once relative to human civilization. Then it is contingent for human civilization. Because it only appears once, it will undoubtedly be more difficult for humans to parse it.

Since this phenomenon has never been observed in the past since the advent of astronomical observations, it can be inferred that the cause of the anomalous disappearance of stars has never occurred in the past few hundred years. If we work backwards, we can conclude that all the physical processes that have been understood by people have been discovered and understood in the past few hundred years. None of this is likely to be the cause of the disappearance of the astral anomaly. Even if the physical process were involved in the event, it would necessarily be only a part of it, not all of it, and there must be something outside of the physical process that has never been understood. A completely new physical process.

This is the difference between an accidental event and a necessary event. This distinction may seem complicated, but to simplify it, it can be explained in one sentence: any theory that attempts to explain the phenomenon must first satisfy the premise that the theory must have a cycle interval of at least four hundred years. Because 400 years is the length of time that human beings have the corresponding observation technology, and at the same time, if the theoretical interval is less than 400 years. It must have caused a similar astral anomaly to disappear within 400 years, and if that were the case, then humanity would have seen it at least once in the past.

And by this standard, nebula occlusion is undoubtedly unqualified, and gravitational lensing is also unqualified. Because these two possibilities have always existed in the universe, and in the past, they have never caused such a star anomaly to disappear. At the same time, Zhang Hong's theory of the cosmic environment is also unqualified, because it also fails to meet this criterion.

Therefore, from now on, any theory that attempts to explain the anomalous disappearance of the astral body must first meet two conditions: first, the phenomenon has nothing to do with the astral body itself, and second, the phenomenon is an "accidental phenomenon" that cannot be explained by any existing theoretical system.

In this way, the possibility that the astral anomaly disappearing event is a "cosmic natural event" is greatly reduced, and correspondingly, the possibility that the astral anomalous disappearance event is "caused by human forces" is greatly increased. And this person among humans naturally cannot refer to human civilization, so ...... It must be talking about some kind of powerful and self-conscious individual or aggregate of individuals.

The term individual aggregate is often called ...... in the common language of human civilization Alien civilizations.

Zhang Hong can naturally figure out the twists and turns, so Zhang Hongcai directly said that Zhao Lan was hinting at the existence of an alien civilization with super power.

In the face of Zhang Hong's questioning, Zhao Lan did not flinch: "The astral anomaly disappearance caused by the intervention of some extraterrestrial civilization with super powers, this explanation is not at all correct. ”

"What kind of extraterrestrial civilization does it take to have the ability to affect many river-level celestial bodies in different parts of the universe at the same time......?" Zhang Hong muttered, "I can't imagine it. ”

"If it is divided according to the classification of the Kardashov index, the civilization that can use the energy of an entire river system is K3 civilization, the civilization that can use the energy of an entire galaxy cluster is K4, the civilization that can use the energy of an entire supercluster is K5, the civilization that can use the energy of an entire supercluster complex is K6, and the civilization that can use the energy of the entire visible universe is K7...... Well, I think that a civilization that can use scientific means to cause the disappearance of so many river-level celestial bodies is at least K6.5. And our human civilization has just stepped through the threshold of K1-level civilization at this moment. Zhao Lan said without hesitation, "That kind of civilization is a real god-level civilization for us, and in the face of such a civilization, we can't have the slightest ability to resist." This is different from the original solar civilization. The solar civilization has reached the K2 civilization level above the reverse fusion layer technology, but their comprehensive scientific and technological strength is not even comparable to our original human civilization. ”

The term "K6.5 civilized ......" silenced all the staff members in the regular meeting.

It was an almost unimaginable super civilization, and for such a civilization, it was possible to destroy a star with a backhand, destroy an entire river system with a blow, or even cause some kind of process to destroy the entire universe. With the meagre imagination of mankind, it is never possible to imagine the existence of such a civilization.

That's a hopeless gap.

"If there really is a K6.5 civilization, and it is really caused by this civilization, then what is the point of all our efforts? Even if our technology develops for another 10,000 years, the most optimistic estimate is that it will only develop to the level of K2.6 civilization...... And we don't know if our human civilization can last for 10,000 years. A colleague muttered. (To be continued.) )
