() As the portal unfolded, a ** professor was teleported in, gradually filling the entire central courtyard.

Lifting the document and looking at the list, to confirm that all the scholars had arrived, Chen Yu closed the portal, walked to the high platform, deliberately scanned the field with a "profound" gaze, and said loudly: "You are all the top experts or educators in natural sciences, and I would like to express my sincere gratitude for taking time out of your busy schedules to come here." ”

"You're not a bureaucrat, you're not in a meeting here, I should have stopped talking nonsense and got straight to the point. But in addition to you, there are more than 14 million ordinary people at the scene. Most of them are not clear about the world, science and technology, and the development and predicament of human civilization. Therefore, some verbosity cannot be left behind. ”

With his hands behind his back, he recalled the copy in his mind for a long time, and said: "Through the Hubble telescope, we know that the universe came from the Big Bang more than 13 billion years ago. If 13 billion years are compared to 13 years, then the solar system appeared 4.5 years ago. The earliest living organisms as we know appeared 4 years ago. The dinosaurs became extinct about three weeks ago. ”

"The first Homo sapiens began to evolve in Africa 50 minutes ago. The Industrial Revolution happened 6 seconds ago. The First Great War took place two seconds ago. As for World War II, the birth of nuclear weapons, Hiroshima becoming a unit of measurement, the landing of man on the moon, the electronic revolution, the information explosion, and so on, it was only a matter of the last second. ”

Humans are awesome!

T +1

What is the relationship between Hubble and the Big Bang? How do you know that the universe is 13 billion years old?

I was born 0.001 seconds ago.

You see, my kneeling posture is not standard.

"Through such a time comparison, it is easy for ordinary people to produce a cognitive error......"

Chen Yu looked at the camera and stretched out a finger: "Human technology has started a big explosion, and the flames of this explosion will continue for a long, long time." ”

"But sorry ......"

"Ordinary people don't know that behind this brilliance, there is endless despair. ”

His voice gradually deepened: "Human beings have entered a bottleneck period. The scientific name for this bottleneck period is called developmental disorder. ”

"At present, the reason why the lives of you and me, especially the Chinese people, feel changing with each passing day, as if they are changing day by day, is not called the explosion of science and technology. In fact, it is just a single industry of the information Internet that is developing rapidly. ”

"In fact, the development of the most important energy sources, power, materials, semiconductors, and even more importantly, fundamental physics has slowed to the point where it is beyond the comprehension of ordinary people, and it is not an exaggeration to say that it has completely stagnated. ”

"Did the audience in front of the screen notice? The darkness hidden under the glory?"

"For example, Moore's Law has long since failed. Fifty years ago, the Saturn V of the Apollo program has not yet been broken through its carrying capacity. The theory of relativity and quantum theory, founded by Albert Einstein a hundred years ago, are still at the forefront of human science in 2020. Mechanics, which was founded by Newton hundreds of years ago, is still unknown to 95% of people in 2020......"

After a slight pause in his voice, Chen Yu shifted his gaze from the camera to the people in front of him: "You know these questions better." ”

The professors looked at each other in silence.

In Huaxia's textbooks, there is a story that has been repeatedly mentioned, that is, how long did it take Jianguo to research nuclear weapons, how long did it take Suwell, and Huaxia only took a few years to develop it. In the same way, there are computers, fighter jets, missiles, satellites, chips, and so on. ”

"Admittedly, these advances are amazing, but in the end, they are just following the path of their predecessors and taking many shortcuts. Few people know that before the Manhattan Project, there was no theoretical support for whether a nuclear bomb could be realized. This also leads me to what I want to talk about next - the difficulty of technology creation. ”

"The most critical and difficult point of a scientific research technology is not the investment of manpower, energy, money and time. It's that we're not sure if the technology will be possible. ”

"Just like controlled nuclear fusion, which is studied by the earth, this is the most critical technology for human civilization to continue, and there is no one. But ironically, to this day, the academic community is still unsure whether controlled nuclear fusion is a seemingly beautiful but useless 'perpetual motion machine'. ”

"To put it more simply, it's like a mentally handicapped teacher who asks questions, and we're not sure if they're inherently wrong. After burying your head in answering the questions, it is very likely that you will die on a question, and you will not get a result. This is the swamp of technology, where the flat ground is full of abysses, and stepping on it is death. ”

Speaking of this, Chen Yu was stunned for a moment, and thought of the teachers of the sixth middle school in his mind......

"A small fork in the tech tree can lead to the disintegration of a former superpower. ”

"The technology tree is a big fork, and even human civilization will cease to exist. ”

"Hearing this, do the audience in front of the screen still think that technology is in an explosive period?" Walking off the high platform, Chen Yu beckoned, signaling everyone to follow him

Without hesitation, the professors followed, leaving the courtyard, through the corridors, around the halls, out of the castle, and into the door of a small castle that was separated.

"The legacy of Albert Einstein and other modern scholars has been exhausted, and human development has inevitably reached a barrier. ”

This also explains the Fermi paradox, why the vast galaxy is not filled with aliens with the Big Bang. We've never seen aliens either. ”

"Because the ongoing tech explosion doesn't exist. Most civilizations will eventually be wiped out in layers of scientific barriers. ”

"Even we human beings are almost locked in this tiny solar system by science in physics, the speed of light, energy, genetics, astronomy, communication and other fields......"

"Why did I add the word 'almost'?"

Under the footsteps, Chen Yu stretched out his hands and pressed on the gate of the small castle and smiled: "The answer is here." ”

"Squeak Quack......"

After the words fell, he suddenly pushed open the wooden door, and the vicissitudes of life and the ancient breath came from within!

The pupils of all the professors present suddenly dilated.

The official staff in front of the screen, scientific research workers, and even ordinary viewers couldn't help but be shocked.

Over here......

It's a sea of books.

Rows and columns, infinite extensions, dense sea of books!

In the high-definition picture of the camera, everyone can see the text on the bookshelf tag in front of them.

……

Turning around, opening his arms, facing the camera, Chen Yu's voice was sonorous and powerful.

"See?"

"As a Lego parenting toy, there are naturally no popular science books for children and teenagers in the 30th century. ”

"And this ......"

"It is the time when human civilization shines the most!"
