Chapter 88: Not related to third parties
These extremely precious ice cores were divided into extremely small ice particles. Then people took out the part formed in the feudal era, placed it in a vacuum container, and slowly heated it, and the tiny bubbles hidden inside it were released.
Gas chromatography-mass spectrometry, used to analyze gas composition, began to accurately measure their composition.
Because so many ice core samples were collected, this analysis had to be repeated hundreds of times. But it didn't take too long. Thanks to the expedition team's overnight overtime, all the relevant data was generated and organized in just a few days.
After that, like other expedition teams such as the tree-ring analysis expedition team, the background radiation expedition team, the microplastic expedition team, the ocean expedition team, and the high-altitude atmosphere expedition team, the data from the polar expedition team was also sent out via radio waves and arrived at the Atmospheric Evolution Laboratory in Dajing City for final confirmation and summary.
A day later, a final analysis report was placed in front of Zhou Cheng.
“First, an analysis of the carbon dioxide content in the Earth’s atmosphere during the feudal era.
By analyzing age markers such as tree cores and ice cores taken between approximately 400 and 1,500 years ago, we have confirmed that the average carbon dioxide content in the Earth's atmosphere during the feudal era was 270 ppm.
Comparing geological research data, human activities during the feudal era increased the carbon dioxide content in the Earth's atmosphere by approximately 2.3%-2.5% compared to the slave age, the Neolithic Age, the Paleolithic Age, and before the birth of mankind.
Zhou Cheng frowned instantly.
Based on our previous speculation and research, we have confirmed that within a range of 10,000 light years, a change of only 1.5% in the carbon dioxide content in the Earth's atmosphere could be detected by an alien civilization with super technology.
And... even in the feudal era when technology was extremely backward, human civilization could have increased the carbon dioxide content in the Earth's atmosphere by at least 2.3%?
In this case... if my previous speculation, that "the Moon Goddess took action against humans because she was afraid of being affected by human civilization", locked the fertility of human civilization, and at the same time, refused to accept the human plan of "locking its own technology and regressing to the feudal era", it would be completely explained.
Because even in the feudal era, the impact of human activities on the planet could already be detected by distant unknown beings.
Going back to the feudal era will not eliminate the threat to human civilization.
After reading the first detailed study on the carbon dioxide content in the earth's atmosphere during the feudal era, Zhou Cheng looked at the second part of the thick report.
"Second, research on the quasi-permanent landmarks left by human civilization on Earth.
The research team conducted detailed measurements of background radiation, microplastics, and the interaction between the Earth's ocean and atmosphere. We have confirmed that human civilization has permanently changed the structure of the Earth's atmosphere.
The high concentration of radioactive isotopes formed by nuclear tests and explosions will remain in the strata and oceans for a long time, and their survival time may even be as long as hundreds of millions or even more than a billion years.
Microplastics and persistent organic pollutants, such as chlorinated biphenyls (PCBs) and dioxins, will also persist for a long time.
Based on the interaction mechanism between the strata and oceans and the atmosphere, we confirm that such substances will also exist in the atmosphere for a long time.
At the same time, because such substances are strongly related to intelligent civilizations - for example, plastics do not exist in the natural environment and can only be produced by intelligent civilizations.
It can be regarded as a marker of civilization, that is, no matter how much it contains, once it is detected, it can be confirmed that there is intelligent life on the planet.
Because it is extremely special and quite different from other natural substances, the super civilization that may exist in the distant starry sky is very likely to have special detection methods for this type of substance.
Even at a distance of tens of thousands of light years, it is still possible to detect it."
Um?
The second paragraph of the investigation report once again surprised Zhou Cheng.
The first paragraph shows that if the reason why the Moon Goddess exterminated human civilization was to "avoid being affected by humans", then it is very reasonable for the Moon Goddess to refuse to accept the plan of human civilization regressing to the feudal era.
But at this moment, the second paragraph shows that if the reason why the Moon Goddess exterminated human civilization was "to avoid being affected by humans", then it would be unnecessary and useless for the Moon Goddess to exterminate human civilization.
The reason is very simple. Even if you, Moon God, destroyed our human civilization, after the technological age, our civilization has left permanent traces on the earth.
This trace cannot be erased.
Even if our human civilization has perished, the super civilization that exists deep in the starry sky can still confirm the existence of intelligent civilization on Earth through these permanent traces.
Then, the blow that is supposed to come will still come, and those who are supposed to be affected will still be affected.
If this is the case, wouldn’t the extinction of human civilization be a futile effort?
If the reason is really to "avoid being affected by humans", then the only reasonable solution for the Moon Goddess is to destroy human civilization before it enters modern society.
In this way, no permanent markers will be left, and the content of various characteristic gases in the Earth's atmosphere will return to normal.
But the Moon God chose to wait until human civilization had already reached modern society before taking action. This...
Zhou Cheng's previous conjecture presented an unsolvable paradox in the face of real evidence.
If this is the case, it only proves that my previous guess that the Moon Goddess wanted to destroy human civilization in order to avoid being affected was wrong.
The Moon Goddess did not attack humans for this reason.
Although his guess was disproven, Zhou Cheng did not feel much disappointed.
The reason is simple. Just as he had said to the first decision-maker before, whether it is proven or falsified, his side's progress will be a big step forward.
At least, now one possibility has been ruled out. My future self no longer needs to invest energy in this conjecture or this direction.
Putting down the report, Zhou Cheng picked up another piece of paper.
There were four short sentences written on it.
“Threatened by us;
The threat model has nothing to do with technology;
The way of existence is unconventional;
Possesses a certain amount of wisdom.”
These were the five conditions Zhou Cheng had originally summarized to define the Moon God's existence. Of course, the first one, "existing on Earth," had been deleted, leaving only four.
Zhou Cheng picked up the pen and solemnly added another condition after the four conditions.
"The threat model has nothing to do with third-party presence; it comes from within us."
This short sentence is the final result of this large-scale scientific expedition.
