Wang Han said: "There are many questions, so let's not go through them in detail one by one, let's choose a few representative questions!" ”

Xu Linfei was also curious to look at the big screen behind her, when she was at home, she also asked her boyfriend about the use of anti-gravity.

It's just that she doesn't have enough knowledge to know too much. Moreover, some may also involve national key projects, and she did not ask in depth.

Ji Zhen browsed the questions presented on the screen and sifted through them one by one.

These topics can definitely only be chosen by Ji Zhen himself, because Wang Han and others don't know the inside story, so the topic selection may involve more in-depth aspects, so they will not take the initiative to choose.

In case of picking a very sensitive issue, they said that they would not be investigated. As for the reason, it is suspected of spying on state secrets.

"Hey, that's an interesting question. When will we enjoy the dividends of anti-gravity technology? ”

Ji Zhen read out the question asked by netizens, and then said with a smile: "I can say here that private individuals and even private enterprises cannot enjoy the dividends of anti-gravity technology." ”

There is no doubt that anti-gravity technology is controlled by the state.

"However, private individuals can enjoy the benefits of anti-gravity technology."

Ji Zhen's words are very inspiring, as the world's first person in anti-gravity technology, he knows the most about anti-gravity technology, and no one must doubt it when he says this.

Not only did the audience sitting below listen more carefully, but the host group on the stage also asked excitedly.

"When will you be able to enjoy this convenience? What kind of convenience is it? ”

Ji Zhen tilted his head and thought about it, and said, "If nothing else, it should be the high-speed rail at the beginning." On the one hand, the state is upgrading the track of the high-speed railway, and on the other hand, it is also introducing anti-gravity devices on the Fuxing. ”

"Once these jobs are completed, the new high-speed rail will be faster, more stable, safer and consume less energy."

Many people wonder why the country has vigorously developed high-speed rail in recent years, instead of developing civil aviation like Europe and the United States?

There's a reason for that.

Huaxia does not have its own large-scale aircraft manufacturing technology and relies entirely on imported Airbus and Boeing, and from the perspective of national defense and security, it cannot hand over all the skies to foreigners.

Although it has developed its own domestic large aircraft, there is still a technological gap with foreign countries.

But that's not the point.

The focus is on oil: our country is a complete oil importer. Don't look at Daqing back then, the current Xinjiang Karamay propaganda oil reserves are very large, in fact, China now relies on imports for more than 90% of its annual oil consumption, mainly in the Middle East, Iran, North Africa, Sudan and other countries.

And the maritime transportation of oil accounts for more than 70% of all oil imports, and the sea must pass through the Indian Ocean and the Strait of Malacca, both of which are controlled by the United States.

Therefore, no matter how large-scale the development of civil aviation is, it will only send our necks to outsiders to pinch, not a long-term solution.

Although China used to be a big country lacking electricity, it is not the same now, and there are more sources of electricity, and it is not easy to be controlled by others.

More importantly, high-speed rail also has many advantages in terms of strategy, such as short- and medium-distance domestic transportation (within 2,000 kilometers), more advantages than airplanes in time, less susceptible to abnormal weather than airplanes, and the volume of transportation is not comparable to airplanes, which are of great benefit to China, a populous country.

The same is true for the military.

Therefore, whether it is civilian or military, the development of high-speed rail is more in line with national conditions. Of course, airplanes are also a must.

It's just that now it's more focused on high-speed rail.

Not to mention the advent of anti-gravity technology now, which has greatly enhanced the practicality of high-speed rail construction, although some of the rails need to be upgraded, but compared to the return, it is really not worth mentioning.

"So when will we be able to ride the gravity-defying high-speed train? Is there a specific time? Wang Han asked.

Since Ji Zhen has already said it, it means that this matter can be discussed by Zhengda Guangming.

Therefore, Wang Han continued to ask in depth.

Ji Zhen shook his head, "It's hard to say, it depends on the progress, but there should be no problem within five years." ”

The country is still very enthusiastic about the construction of anti-gravity high-speed rail, and now although Ji Zhen is not involved in it, other experts are responsible for overcoming it, but once they encounter problems, they will still come to the door.

In this regard, Ji Zhen has been prepared for a long time. Not only high-speed rail, but also other aspects such as aircraft, ships, aircraft carriers, rocket launchers, etc., the project department will come to him when it can't solve it.

"Five years may not be a short time for an individual's life path. But for the anti-gravity scientific research task, it is actually not long, five years, anti-gravity high-speed rail, we are looking forward to. ”

Wang Han said calmly, as if to let people know the difficulties of scientific research, so that people can't help but have respect for such a group of people.

After this topic came together, the audience seated below all raised their hands to indicate that they wanted to ask questions.

Wang Han motioned to the staff to hand over the microphone.

Soon, Ji Zhen clicked on a classmate in the front row, and then the other party stood up and asked Ji Zhen, "Professor, can you tell us more about the situation of the anti-gravity high-speed rail?" For example, you just mentioned that it is faster, more stable, safer, and more energy-efficient. ”

Ji Zhen smiled, "I can only say that from the perspective of anti-gravity technology, high-speed rail will produce these better changes, but I am not from the high-speed rail project team and I don't know what the specific and detailed changes will be." ”

"After all, it's not just a matter of anti-gravity devices, it's about high-speed rail technology."

The classmate sat down, and then someone stood up and asked.

"Professor, does the launch of anti-gravity high-speed rail within five years mean that we are going to enter an anti-gravity society in an all-round way?"

Ji Zhen smiled and waved his hand, "First of all, there is no concept of an anti-gravity society. ”

"Secondly, the current anti-gravity technology is not particularly strong, so there is still a long way to go before the full use of anti-gravity."

"The various anti-gravity cars in the movie, and even the anti-gravity community built in the air, are not realistic for the time being. Not for at least a decade, because it involves more than just anti-gravity technology, but also requires other technological breakthroughs. ”

There were a lot of people who wanted to ask questions, but Wang Han still grasped the rhythm, and Ji Zhen didn't reveal much when he answered the questions.

Ji Zhen who can say it will say it, and he will definitely not say what he can't say, as for the ambiguity and inconclusion, Ji Zhen is also cautious.

Because the audience is very enthusiastic, and Ji Zhen's status is not ordinary, the recording time this time is very long.

Fortunately, the program team was prepared, and the sofa on the stage did not make Ji Zhen and Xu Linfei tired.

Moreover, there were also staff members who handed over a few bottles of Cestbon over.
