Edward Witten was a Jew, with gray hair, a warm smile, and deep, bright eyes, as if he had a visible intelligence.

Lin Han also smiled and shook hands with him: "Hello, Professor Witten." ”

"Please come in. ”

When he entered the villa, he met Professor Witten's family again, and after greeting him, Lin Han sat on the sofa and chatted with Witten.

Vientiane has been digging the foot of the wall quite a lot recently, and Witten certainly knows Lin Han's intentions.

So while chatting, he said, "Lin, several of my friends have been invited by you to work in the Vientiane Laboratory...... To be honest, I'm curious about you guys, like the "fermion vertical traction meter", how does it work? It seems to me that it is completely outside the theoretical framework of modern physics. ”

"This ...... I'm sorry, but I can't share any information with you. ”

Witten said a little half-jokingly: "If you tell me how the fermion vertical traction meter works, I will pack my luggage and go to Huaxia Yunzhou now, what do you think?"

It has to be said that this condition does have a certain attractiveness. As one of the world's top scientists, Witten will be treated as a guest of honor wherever he goes, and Vientiane is no exception.

Although there have been many Nobel Prize-level scientists settled in Vientiane Laboratory, and Yao Qizhi is responsible for a lot of scientific research and administrative work at the Singularity Research Institute, no one will be too big.

If the so-called "fermion vertical traction instrument" does exist, or if there is such a related physical theory, Lin Han may have to reveal some to Witten.

"I think you should understand that Vientiane First Laboratory has a close relationship with Huaxia officials, and I really have no right to disclose it due to strict confidentiality requirements. He didn't hesitate to dump the pot on the government.

Witten didn't doubt it, but nodded with some regret: "Alas, I originally thought that I could find some breakthroughs in you, those two tractors are really amazing." ”

Lin Han said: "Although there are some confidential contents that cannot be disclosed, there is no doubt that Vientiane Laboratory is one of the best laboratories in the world, so this time, I sincerely want to invite you to join us." ”

"I know that the Vientiane laboratory is very good in all aspects, with sufficient funding, a strong scientific research atmosphere, and of course, that surprising private office......"

Under Lin Han's great attention, the private office of Vientiane Laboratory soon developed, and the service became more and more thoughtful, and the reputation was excellent.

Housing, medical care, and children's education for scientific researchers...... Even for all private matters such as emotional problems, interpersonal contacts, personal disputes, etc., the private office can provide professional counsel and necessary assistance.

There is even an "application for private trusteeship", as long as the scientific researcher takes the initiative to apply, then all his private affairs in the future will be represented by the private affairs office, except for scientific research tasks, there is no need to think about anything, and he does not listen to things outside the window.

The private office is very convenient, especially for some introverted scientific researchers, this office is simply a godsend.

Based on this, some high-functioning autistic patients have also joined the Vientiane laboratory and devoted themselves to the scientific research work that they adapt to and love.

Now, the private office has become one of the trump cards of Vientiane Laboratory to attract talents, attracting many outstanding scientific researchers.

Of course, the importance of private offices is mainly for middle-level scientific and technological workers, and for senior scientists and engineers with huge reputations and rich net worth, it is not so attractive.

After all, with their personal wealth and social connections, they will not encounter any trouble in private matters.

For a scientist of Witten's calibre, a private office is at best a convenient and comforting idea.

He continued: "But these shouldn't be that important, at least I don't think it's enough to attract Yang and Yao." ”

Lin Han smiled: "Professor Witten, if you take a walk around the laboratory, you can experience that unique atmosphere. ”

As he spoke, he took out a document from the bag he was carrying and handed it over: "Abundant funds, a strong and cohesive scientific research team, it is not as simple as it sounds. ”

"We have a lot of ambitious plans in place, and I'm sure you know a little bit about the Global Environmental Report. In fact, there's a plan here, and it's a lot like it's made for you. ”

Witten took a look and was immediately surprised: "Pangu plan?"

He glanced at Lin Han, and then said, "I know 'Pangu', he is a god who opens the chaotic world in Chinese mythology......"

"Yes, I think this plan is as magnificent as the myth of the opening of the heavens. Lin Han smiled slightly, "The third content of it, which I just said, is like a plan tailored for you. ”

Witten did not directly turn to the third item, but kept reading it at an astonishing browsing speed, and at the same time exclaimed: "Transform the biological chain, transform the geography...... It was truly an incredible idea. ”

"Obtaining hydrogen?" he couldn't help but stare at the third item.

Lin Han said: "As we all know, hydrogen is the lightest element in the universe, and the gravitational pull of small celestial bodies cannot bind a large amount of hydrogen, and hydrogen is precisely the core component of water and organic matter, which makes the content of hydrogen an innate restriction on the reproduction of life on planets. ”

In the endless universe, the conditions for the birth of life are harsh.

To derive life, basic chemical elements are first needed. Looking at the periodic table, the elements suitable for "building" life are none other than carbon, hydrogen, and oxygen, and only they can easily form a long chain with infinite variations.

Carbon and oxygen are nothing, but celestial bodies that contain a lot of hydrogen are all huge beings, such as the Sun, Jupiter, and Saturn.

If nothing else, these celestial bodies can wipe out all life with just a huge gravitational pull.

Life needs hydrogen, but where there is the most hydrogen, life cannot survive. This harsh condition is almost paradoxical.

“…… In my opinion, when people look for planets with water, they are actually looking for planets with hydrogen. If there is a way to obtain hydrogen in large quantities, the water problem will be solved. ”

Looking at the "Pangu Project" in his hand, Witten's expression was a little serious, as if he was contemplating.

After a while, he said slowly: "As the plan says, obtaining a large amount of hydrogen requires a major breakthrough in physics...... However, I believe that there is only one most critical problem, and this is the biggest problem facing humanity for a long time. ”

Lin Han's expression moved: "What do you mean ......?"

Witten lifted his glasses and said:

"Energy. ”
