As the host, Wallace is not a fool. He frowned and thought, and asked slowly: "Has humans been considered to have passed this kind of civilization filter?"

"It's possible," said biochemist Dr. Pim, "The big filter is not a conventional species evolution, for example, from apes to humans,

And at least one in a million or even one in a billion can pass the level of the chance to be regarded as a large filter.

For example, the first blocking filter is likely to be set at the beginning of life, that is, the emergence of prokaryotic cells, or the evolution from prokaryotic cells to eukaryotic cells."

"That's right." Reed Richards further explained: "It took the Earth a billion years to produce prokaryotic cells, and it took two billion years to evolve into eukaryotic cells.

If this is the first wall, it means we have successfully passed."

Nair DeGras Tyson, who once filmed the documentary "Traveling to the End of the Universe", interjected: "This is also the reason why humans want to explore other planets in the solar system."

"Oh?" Wallace smiled and said, "If we can find prokaryotes, eukaryotes and even intelligent creatures on Mars, then it would prove that the large filters are real, and we humans are not alone?"

All the scientists looked at each other, and finally Yuraj smiled bitterly and said in an Indian accent English: "No, no, no, no, no, whatever we found on Mars, is extremely bad news."

"What does it mean?" Wallace became even more confused.

"That's right." Raj spread his hands and explained: "If we discover prokaryotes on Mars, it means that prokaryotes are likely to be everywhere in the universe, which means that the emergence of prokaryotes is not the first big filter.

If we discover eukaryotes and even complex life on Mars, it means that the emergence of complex life is not the first big filter.

This means that human beings are not special, not survivors are deviating. The first big filter is still ahead of us. As the human civilization on Earth is developing, it may hit the filter at any time and encounter rapid destruction."

Raj's Indian accent in English looks a bit funny, but the content makes people fall into an ice cave.

Wallace felt that breathing was a little difficult. He took off his tie, poured himself a glass of water, swallowed it, and then said, "It sounds scary."

"It's really scary." Li Ang smiled and said, "In the Fermi Paradox, no news is the best news. For humans, no matter what they find, it's bad."

"But now..." Wallace pointed at Schwarz's throat in the screen with his finger, "Is this good news?"

"To some extent, yes." Li Ang laughed: "With the Zitari people as samples, it is at least proved that humans will not encounter the blows of large filters before entering the wormhole."

"Huh, this is equivalent to the Chitari people walking in front of us to explore the way?" Wallace breathed a sigh of relief and said with a smile: "What is this? Cross the river by feeling the stones?"

Everyone smiled, and Nair said casually: "Not necessarily, and the Zitarry people may not be able to resist the large filters.

If the effect of the large filter did not exist in the past, then it is very likely that the Milky Way happened to be in a golden period conducive to the development of intelligent life.

There is a giant black hole in the center of the Milky Way. All kinds of terrifying disasters erupt, such as gamma-ray bursts that radiate outwards periodically.

This disaster will cleanse all life in the galaxy every once in a while and act as a filter.

In short, we are likely to be in the tranquility stage before the arrival of the Great Filter and in this stage of the universe - there are not many higher civilizations ahead of us, let alone third-level civilizations."

This mysterious theory made the host Wallace frown in pain. The old man struggled to digest the information. After a long time, he slowly said: "The Zitaris, who created Schwarzsy's throat in the sky in the New York, are the higher civilizations in this quiet stage, just like us?"

"It's still possible."

Li Ang smiled and said, "But from another perspective, the emergence of the Zitari people, who are also of higher civilizations, is likely to prove that the large filter does not exist.

If the large filter did not exist, why did we not contact the Zitaris before them, and even observed any traces of higher civilizations?”

"Oh?" Wallace frowned and said, "It is impossible that we happened to encounter an advanced civilization at this time point?"

"There is such a possibility, but a bigger problem has come. The emergence of the Zitaris proves that the earthlings are not alone, and at the same time, it also proves that there must be more advanced civilizations in the Milky Way.

Tens of thousands of higher civilizations have transformed their surrounding environments in various ways in the Milky Way, and they can be discovered by humans no matter how they say it is."

Li Ang spread his hands and said, "There are several reasons why we have not observed it.

1. Higher civilizations have long visited the earth with a history of 4 billion years, but we have no relevant records.

2. Higher civilizations are clustered in the middle of the Milky Way, and humans are like remote areas, savages in the mountains and valleys, and they don’t know at all. After all, we cannot observe beyond the speed of light.

3. For higher civilizations, there is no need to conduct extraterrestrial colonization. They can drag planets or build Dyson balls and build a livable zone next to Dyson balls. Even all members upload their consciousness to the online world and enjoy happiness there.

4. Dark Forest Theory. All higher civilizations in the Milky Way are extremely aggressive. Any behavior that exposes its own position will be fatally hit by other civilizations, so no civilization has exposed its own position.

5. There is a supreme super civilization. This civilization monitors everything in the Milky Way. When any intelligent species develops to a certain extent, it will start to destroy it. In other words, there is only such a super civilization in the Milky Way.

According to mathematical models, this possibility is extremely great - humans can cross from modern times to modern times in 200 years, so if humans are given 20,000 years or even 200,000 years or 2 million years, we might really be able to grow into super civilization.

However, the appearance of the Zitari people denied this point. If there was such a super civilization, the Zitari people would have died long ago."

"Oh?" Wallace frowned and said, "Can't the Zitaris be super civilized?"

"It's still far away." Li Ang spread his hands and said, "Their Schwarzish throats are magical, but they are not as magical as they can monitor the entire Milky Way.

The sixth possibility is that human cognitive structures are very different from alien species. If the human brain operates much faster or slower than other civilizations, then we cannot understand their message at all."

"The brain runs at a speed?" Wallace frowned and said, "What does this mean?"

"Haha, assuming that the brains of alien species are ten thousand times faster than humans, it means that they only need electromagnetic waves with very short frequency to communicate - humans cannot extract sufficiently effective information from it."

Reed Richards said calmly: "If the brains of alien species are far slower than those on Earth, then it may take them years or even decades to finish the word "Hello" - humans are also unable to extract effective information from it. We will only treat those fluctuating electromagnetic wave communication as meaningless white noise."

"So that's it." Wallace nodded and let out a breath of turbid air: "Then we can only hope that there is not much physiological gap between the Zitaris and us."

"Haha, everything is possible in the world. Even if the Chitari people are a group of white silk maids who are light and soft and easy to knock down, I wouldn't be surprised."

Li Ang said calmly: "The seventh possibility is that higher civilizations know and detect our existence. They are like a group of generous elders, looking down at our free growth, and have extremely strict restrictions and prohibiting contact or direct interference with lower civilizations.

Or, higher civilizations exist around us, but we simply cannot effectively observe them.

Just as ants cannot understand humans, we cannot understand the way of existence and communication methods of higher civilizations - they may even be abstract existences like the laws of the universe, standing quietly, neither sad nor happy."

This abstract expression puzzled Wallace. He glanced at the scientists present and said slowly, "Well, dear doctors, you are the smartest people on earth. Please tell me how can we confirm that the Zitaris came with a peaceful attitude?"

Hank Pim was silent, Reed Richards was thinking, Tony Stark raised a dull smile on his lips, but his fingers were tightly holding the suitcase and refused to let go.

In the end, Li Ang broke the silence, "Of the possibilities I mentioned before, the first to the fifth are the most likely, but no matter which one is, the Zitari people will not have the third type of civilization."

Wallace spread his hands and smiled bitterly, "But you also said that only a few hundred or even thousands of years of technological generation difference will be enough to form a comprehensive crush."

Li Ang just smiled plainly and lay heavily on the sofa, "No matter whether they have the power to crush the earth or not, they will sit down and negotiate."

"Who can guarantee peace?"

"Peace is not obtained through guarantees, Mr. Wallace." Leon said gently: "Peace is rewarded by the strong to the weak."

Before he finished speaking, Schwarzsey's throat suddenly shone brightly in the picture, and the pillar of light penetrated into the sky was like a miracle, overtaking New York.

The steps of aliens are approaching.
