When Professor Huo was giving a report, Li Erdan also listened carefully, resting his hands on his cheeks, he had the image of a quiet and handsome man, and he would smile when he came across interesting points of knowledge that he could understand and agree with. He nodded, and he would frown when he encountered something he didn't understand.

Professor Huo didn't say it alone, he has a full-time report meeting team to serve him.If his thoughts were unclear, or the speech synthesis was wrong, one of the men on his team would pick up the microphone and explain.In addition, a large projector in the lecture hall is also playing a ppt, and a team member is helping him turn the pages, and the clear knowledge points in the ppt are exactly what the professor is talking about.

It can be seen that the professor's report meeting has also been prepared hard in advance

After flipping through the brochure, he stopped flipping through it. Through the introduction of the brochure, he already had a great understanding of the professor's life.

Professor Huo is definitely a genius!

Principal Hamilton was a little surprised to see that Li Erdan seemed to be really interested in the professor's report. He was surprised that a Chinese medicine practitioner was interested in cosmology.He prepared a booklet about the professor's life for Erdan before, just because he was worried that Li Erdan would not be interested in the professor's report, and asked him to read it when he was bored to pass the time.He invited Li Erdan to listen to Professor Huo's lecture, not as simple as listening to the lecture, but with Xiao Jiujiu.

"Do you understand?" Principal Hamilton asked Er Dan.

"I don't understand." Dumb.

"Then you,?" Hamilton asked.

"Can't I just pretend?"

Principal Hamilton, suddenly broke out in sweat!

The professor's voice synthesized by the intelligent voice system sounded again in the spacious and bright lecture hall. He said: "Our world now has a highway network of nearly 40 kilometers, of which the Huaxia Kingdom in the East takes the lead. In the next five years, the total mileage of the expressway network will exceed 50 kilometers, which can circle the earth's equator more than ten times. The existence of expressways connects a country, and even countries, continents and continents. People's travel, living, and transportation have become more convenient. Now I want to tell you that in our universe, there is also a complex and closely intertwined 'highway network'. This highway network not only connects a planet and Another planet is connected, and a galaxy is closely connected to another galaxy, even if they are separated by trillions of light years, and even if they are not in the same time and space, this close connection is always there. This highway network is nothing else, it is The wormhole that existed in our theory for a long time. In order to distinguish it from the narrow channel of the Einstein-Rosen bridge that we are familiar with, my expressway network channel is called a wormhole in the narrow sense for the time being, because it is relatively large, then Einstein- Rosen Bridge is a generalized wormhole, and it is relatively small."

Cosmic wormholes, even kids know it, and even compared wormholes to highways, as someone said earlier, but the wormholes in the universe are intertwined into a dense and complicated highway network, the professor’s The formulation is very novel.

Li Erdan, who has not graduated from elementary school, has no reason not to understand the professor's words.At this time, his facial muscles were relaxed, and he was smiling, showing that he was very interested in the professor's words.

The professor continued: "Wormholes formed by space-time distortion in a broad sense, that is, Einstein-Rosen bridges, are also called quantum wormholes, and miniature wormholes are relatively narrow, so narrow that even the tip of a needle cannot be inserted. Its entrance is difficult to open. The narrow wormhole I want to talk about is just the opposite. Its aperture is generally relatively large. Even a small one can accommodate a Boeing 747. A large aperture can accommodate a star or even a galaxy. Once, We want to build a lunar ladder to connect the earth and the moon, so that we can connect the earth and the moon, exploit the mineral resources on the moon, and even settle on the moon. Of course, this lunar ladder is only limited to the mind so far. In fantasy, it is not so easy to build it, and the resources consumed will be astronomical. If it is feasible to build a ladder to the moon, then it is not so easy to build a ladder to Mars. Building a ladder to Jupiter is even more It is even more difficult, and it is impossible to build a ladder to climb Sirius nine light years away from our earth."

The teachers and students in the audience burst into laughter. Of course, the applause is also indispensable, not for anything else, just to teach this profound and simple statement.Professor Huo's words also aroused the interest of the teachers and students in the audience.

The cosmic highway that Professor Huo talked about, is it a magic horse?It's so amazing.

"Actually, the ladder to the moon is unnecessary, the ladder to Mars is unnecessary, the ladder to Jupiter is unnecessary, and it is equally unnecessary to build a ladder to Sirius. You must all want to ask me now, Professor Huo, why is the ladder Don’t need it? Well, even if you didn’t ask, I still want to tell you the answer. The answer is the cosmic highway I want to talk about. I can tell you without any concealment that there is a ready-made highway between the earth and the moon. There is also a highway between the earth and the fire, and there is also a highway between the fire and the moon."

A student in the audience couldn't help asking, "Is there really only one? If there is only one, there will be traffic jams. Is it okay to have two? Actually, I think there are a hundred or a thousand."

The student's words were clearly skeptical!

The professor would not get angry because of a doubt, he didn't take it as disobedience, and then said: "One, and there will only be one."

When the professor was speaking, the ppt turned to a new page with the help of the assistant.This page of ppt is a picture. In the picture, there is an earth and a moon. There is a channel connecting the earth and the moon with a spiral spring. The channel is long and thin, with two large ends and a small middle.

The professor's wheelchair turned in one direction, and now he was facing the ppt, and said: "The existing ladder to the moon is like this, a spiral ladder made of gravitational waves, and a wormhole that only belongs to the earth and the moon. This wormhole is An accidental discovery when I was doing theoretical derivation, I don’t know much about many aspects like everyone else.”

Of course, there is only one picture, which certainly can't explain anything.When the assistant turned another page of the ppt, and a wave of dazzling formulas appeared, the suspicion and disdain in my heart dropped by more than half.

It’s not a bragging, the formula deduced by Professor Huo on the picture, not many people on the whole earth can understand it, so that the eyes of the teachers and students here are all black, and most of the teachers and students don’t look at it after a few glances , Immediately took out the paper and pen and wrote down the formula.
