As the portal continued to unfold, waves of professors were teleported, gradually filling the entire central courtyard.

He raised the document and looked at the list and confirmed that all scholars had arrived. Chen Yu then closed the portal, walked to the platform, deliberately glanced at the audience with a "deep" gaze, and said loudly: "Everyone is the top experts or educators in the natural discipline. I would like to take time out of my busy schedule. I would like to express my sincere thanks."

"Everyone is not a bureaucrat, and I am not in a meeting here. I shouldn't be talking nonsense and get to the point. But in addition to you, there are more than 14 million ordinary people paying attention to the scene. Most of them are not very clear about the world, technology, and the development and difficulties of human civilization. Therefore, some long-windedness cannot be left behind."

He raised his hands and recalled the copy in his mind for a while and said, "Through Hubble, 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 will appear 4.5 years ago. As we know, the earliest living organisms appeared 4 years ago. Dinosaurs became extinct about three weeks ago."

"The earliest Homo sapiens began to evolve in Africa 50 minutes ago. The Industrial Revolution took place 6 seconds ago. The First War took place two seconds ago. As for World War II, the birth of nuclear weapons, Hiroshima became a unit of measurement, human moon landing, electronic revolution, information explosion, etc., it was just the last second."

【Humans are awesome!】

【Awesome+1】

[What is the relationship between Hubble and the Big Bang? How do you know that the universe has a history of 13 billion years?]

【I was born 0.001 seconds ago.】

[Up master! Look at the standard of my kneeling posture.]

"Through such time comparison, ordinary people are prone to a cognitive error..."

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

“But unfortunately…”

"Ordinary people don't know that behind this glory is endless despair."

His voice gradually became deeper: "Humans have entered a bottleneck period. The scientific name of this bottleneck period is called development barrier."

"The reason why you and me, especially Chinese, feels like their lives are changing with each passing day is that it is not called a technological explosion. In fact, it is just that a single industry of information Internet is developing rapidly."

"In fact, the development of the most important energy, power, materials, semiconductors, and even more important basic physics has been slow to a point where ordinary people cannot understand it. It is not an exaggeration to say that it is completely stagnant."

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

"For example: Moore's Law has long been invalid. The Saturn V, which was planned fifty years ago, has not yet been broken through its carrying capacity. The theory of relativity and quantum theory founded by Einstein a hundred years ago, is still the forefront of human science in 2020. Mechanics founded by Newton a few hundred years ago, is still 95% of people who do not understand it in 2020..."

After a slight pause, Chen Yu turned his gaze from the camera to everyone in front of him: "You should know more about these questions."

The professors looked at each other and remained silent.

"In China's textbooks, there is a story that has been repeatedly mentioned, that is, how long it took for the Jianguo to study nuclear weapons and how long it took Su Weir. China only took a few years to develop it successfully. The same ones include computers, fighter jets, missiles, satellites, chips, etc.."

"We must admit that these progress is amazing, but in the end, they only followed the path of our predecessors and took many shortcuts. Few people know that before the Manhattan Project, there was no theoretical support for whether the nuclear bomb could be achieved. This also led to the difficulty of creating technology in what I want to talk about next."

"The most critical and difficult point of a scientific research technology is not the investment in manpower, energy, money, and time. It is because we are not sure whether this technology can be realized."

"Just like controlled nuclear fusion studied globally, this is the most critical technology for all mankind to continue civilization, no one. But ridiculously, the academic community is still not sure whether controlled nuclear fusion is a 'permanent perpetual motion machine' that seems beautiful but is actually useless."

"To put it simply, just like a question asked by a mentally retarded teacher, we are not sure whether these questions are wrong in themselves. After answering the questions, it is likely that they will be counted until they die on one question, and they will not get a result. This is the science and technology swamp, where the flat ground is full of abyss, and you will die if you step on it."

Speaking of this, Chen Yu was stunned for a moment and thought of the teachers of the No. 6 Middle School in his mind...

"A small fork in the technology tree point caused the disintegration of a once superpower."

"A big fork in the science and technology tree point will not exist anymore."

"When hearing this, do the audience in front of the screen still think that technology is in an explosion period?" Walking down the platform, Chen Yu waved and signaled everyone to follow him

Without hesitation, the professors followed closely behind, left the courtyard, walked through the corridor, walked around the hall, walked out of the castle, and came to the gate of a separate small castle.

"The legacy of modern scholars such as Einstein has been exhausted, and human development has inevitably reached a barrier."

"This also explains the Fermi Paradox, why the vast Milky Way is not filled with aliens from the Big Explosion of Technology. We have never seen aliens before."

"Because the continuous technological explosion does not exist, most civilizations will eventually be destroyed in layers of scientific barriers."

"Even we humans are almost locked in this tiny solar system by science in various fields such as physics, speed of light, energy, genes, astronomy, communications..."

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

With his feet, Chen Yu stretched out his hands and followed the gate of the small castle and smiled: "The answer is here."

"Squeak qqq..."

After saying that, he suddenly pushed open the wooden door, and the vicissitudes and ancient aura came from inside!

All the professors present suddenly had their pupils dilated.

The official personnel, scientific researchers, and even ordinary audiences in front of the screen were involuntarily shocked.

here……

It's a sea of ​​books.

Rows, rows, endless extensions, dense ocean of books!

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

【atmospherinobotdispeal】

【l-gateinsight】

【naniterepaiystem】

【syncthetis】

【darkmatterpower】

【enropireuion】

【mega-engineering】

【extradimensionalweaponry】

【seletedlineages】

【asensiontheory】

【…】

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

"Did you see it?"

"As a Lego parenting toy, there are no popular science books for children and teenagers in the thirty-century."

"And this..."
Chapter completed!
