This is the end of this historical meeting, without much discussion, and the people slowly leave in silence. Ｘ

The appearance of the "Great Filter" is too shocking, and the extinction of a powerful civilization is revealed to the world.

Yes, it's right in front of you, and you can completely touch its coldness.

Even if humanity knows, so what?

Got it, so what?

Yu Yifeng frowned and left the venue, his mood was dim and low, and he couldn't even hear what the people around him were discussing.

Controlled nuclear fusion, a problem that the Knick civilization has not solved in the end, is a huge problem that mankind is about to face......

Humanity will have to contend with it......

Whether we can get through this hurdle is really a question.

On the surface, the "big filter" is a scientific and technological barrier formed by the ultra-high difficulty of "controllable nuclear fusion technology".

Without the enormous energy provided by nuclear fusion, the sea of stars would be an empty word.

If the vast majority of civilizations have not even invented "controlled nuclear fusion", what kind of interstellar civilization can we talk about? Therefore, interstellar civilizations are so rare.

All I can say is...... A dark, hopeless future.

"Controlled nuclear fusion, because of the oversimplification of theory, directly lures almost all low-level civilizations to the same incorrect path of 'magnetic confinement'. This trap wears away every civilization's confidence and patience in it. ”

Or ...... It's not that the path is incorrect, it's that it's so difficult, so high that it's inconceivable, unimaginable, so high that there's no end in sight. ”

The great sage of the Knicks civilization did not completely deny this path in the end.

According to this reasoning, no matter how difficult it is, "magnetic constraints" are not impossible, they still have a certain degree of feasibility, but the difficulty is outrageous.

"If a civilization has enough time, it can keep progressing. When the technology accumulates to a high enough level, it can still come up with "controllable nuclear fusion technology"! ”

"Yes, theoretically possible."

It's just that the Nix civilization is unlucky, it is a geothermal civilization, and in the case of a lack of sustainable energy, their population explodes uncontrollably. So when they ran out of nuclear energy, they fell into a state of apocalypse.

"But...... What if it's a light-based civilization? Yu Yifeng frowned and thought, deducing this situation.

Take, for example, the earth.

Even if the earthlings run out of fossil energy, will humanity be desperate enough to fall into a state of apocalypse?

High probability...... No, because the earth has an infinite amount of solar energy, at least it can survive without a life-and-death crisis.

The energy of solar radiation is huge, and the total power of solar energy reaching the earth's surface is 1.7*10^17 watts, which is equivalent to hundreds of thousands of times the world's electricity consumption!

Almost all wind, hydro, fossil fuels, are essentially due to solar energy.

Therefore, even if the people of the earth run out of fossil fuels, they will not fall into a state of despair and economic recession if they only use solar energy. According to the size of the population before the destruction of the earth, even if the fossils can be used up, they can still barely survive.

If this is calculated, the earthlings have almost infinite time to develop......

According to the reasoning of scientists, most civilizations in the universe should belong to a light-type civilization similar to the earth! The vast majority of civilizations, as long as they do not die, can develop steadily for a long time.

But...... It is also a fact that the universe is so silent.

In other words, these illuminated civilizations with almost infinite development time are still blocked by "controlled nuclear fusion"!

The reason can only be attributed to civilization itself!

"The first possibility is that after the fossil energy is used up, the earth's civilization is plunged into war due to economic recession. Especially when fossil fuels are about to run out and haven't run out yet...... Particularly dangerous! ”

"The second possibility is that civilization does not progress indefinitely because of the existence of certain internal factors. After their technology has developed to a certain extent, it has come to a standstill. ”

Yu Yifeng laughed self-deprecatingly: "In the later stage, after the economic recession, civilization will barely survive, how can we develop high technology?" ”

From the development of the Knicks civilization, we can already get a glimpse of the leopard...... Many of their technologies came to a near standstill in the later period, and only a few were developed. This is actually a social problem.

"It's really desperate, sometimes ignorance is a good thing......" Yu Yifeng thought silently. When he went from a technological problem to a social problem, he felt a deep sense of despair.

However, these social problems are not the ultimate essence.

If this social problem, which most civilizations encounter, has a creepy identity, then there must be a deeper reason......

In other words, he and Yuriko once discussed, and there are some problems with the "essential philosophical system" that constitutes the genes of life.

It needs to be traced back to ...... essential philosophical question of "why life is alive".

Yu Yifeng believes that this is the ultimate explanation, and it is the best explanation for the "big filter".

Because of genetic problems, after civilization has developed to a certain height, it has fallen into the trap of "pleasure", "comfort" and "capital", and has lost the momentum to move forward.

It's not just the Knicks, it's ...... The vast majority of civilizations in the universe!

He sighed again, at this moment, the joy of obtaining Nix technology was gone, and there was only a deep sadness in his heart.

Like a white mist, blindfolded.

It is not only sad about the tragic fate of the Nixes civilization, but also worried about the ultimate fate of the new human civilization, and even sad for the vast majority of civilizations...... They were all bothered by the same question!

The baton has been passed to the hands of the new human civilization.

If the new human civilization cannot produce nuclear fusion, humanity will remain on this dark planet until ...... Perish!

Yes, although there is a large amount of methane left here, there is also a large amount of oxygen, and human beings will not need to worry about energy for tens of thousands or even hundreds of thousands of years.

But...... The Knicks once had 100,000 years of energy!

They...... That's how it perished!

It's not just Yu Yifeng who is smart.

A long-lost sense of despair hangs over Noah's society, and almost all scientists toss and turn, unable to sleep.

The Great Filter is so desperate that even if we know the truth about it, it is difficult to overcome, difficult to bypass.

There it is, impartial, impassable; It is a majestic mountain that straddles the universe and blocks the path of countless civilizations.

Long nights, hard to sleep, hard to sleep.

The long night is eternal in the universe.

Professor Ding Yidong sat up from the bed in the middle of the night, and suddenly ran outside to hug his head and cried, tears rolling down his eyes. This crazy giant of science has never been so vulnerable.

Dr. Rimbaud leaned against the head of the bed, wiping away tears. Her wife whispered comfort, but didn't know what was happening......

Dr. Felix was working non-stop in front of the computer. The screen was blurry, and he wiped his eyes hard and continued to work.

The strength of the individual seems so weak in front of this mountain, like a mayfly shaking the mountain, and he can't even take the first step of this mountain.

Only ...... The power of the entire civilization can confront the mountain peaks!

Yu Yifeng got up from the bed,
