The boy sat still, Wu Mo couldn't see from this angle, his eyes were about to lose focus.

For a scholar, or for a student, this refers to a real student, a person who really focuses on learning knowledge, delving into knowledge, and taking exploration as their ambition, they have made great efforts, and have gone through a long time to obtain what they think is 'right' through reading, calculus, doing problems, exams, experiments, and practice, and in the process they have poured their lives and blood, and if one day a person suddenly comes to them, points to their nose and tells them: "You idiots, Everything you've studied all your life is wrong! What's even more sad is that you are foolish enough to believe that it's true. ”

Will they really accept it?!

Hundreds of years ago, the theory of relativity was proven correct, and after Newton's classical mechanics was overthrown, the established physicists in physics committed suicide by at least three digits.

This boy is the elite of the School of Physics, he chose this major is to become a generation of scholars, he has worked hard to this point and paid a lot of effort, from the first day of his freshman year, he started studying in the laboratory at four o'clock every day, and ended at eleven o'clock in the evening, in the past four years, he has read thousands of professional books, it is intensive reading, every page, every formula, every theory, he has studied it accurately, not like Wu Mo's rough reading, he also applied to his tutor for hundreds of laboratory use rights, He has successfully carried out all the experiments he knows, looking at hundreds of millions of students all over the world, he is the ultimate in learning, his talent is also one in a thousand, and he is confident enough, as long as he is given enough time, he will definitely be able to go farther than most people on this road.

After paying so much and spending so much effort, now it is almost ruined by these words of Camille.

He didn't doubt the authenticity of Camille's words, with the identity of the other party, there was no need to lie to him, or rather, this is a good thing, it is much better to know the mistake in advance than to know it in the future, but if this mistake is pointed out, then what he has learned in the past few years will basically have to be reconsidered.

"I'm sorry to say this to you, I hope it doesn't affect you." Camille owes money.

This is indeed a very fierce news, Wu Mo speculated in his heart, this matter Camille has never said to others, especially not to the Europa League, if it is an unknown junior who announced the news, then others will definitely listen to it as a joke, but if it is Camille..... With her popularity, even if people in the industry don't believe it, it will cause a big fluctuation in the scientific community, although they are still students, but with their level they are half of the 'industry', there is no reason not to know.

So what is she trying to do here today when she is talking to us students about this? Wu Mo pondered.......

Then, a flash of light flashed through his mind.

He stood up, and all eyes were on him for that moment.

"Professor, you just said that some of the humans have successfully reached an alien galaxy a hundred light-years away?!"

"Yes," Camille affirmed.

"Professor, then I have some problems, even at the speed of light, it will take at least hundreds of years to reach a place beyond a hundred light years, and it will take hundreds of years for the signal to pass back, and it will take at least two hundred years to come and go, even if the speed of light changes at this stage, it is impossible to deviate this time to more than 30 years, which does not make sense in time."

This is a question, and one of these students today who is the first to question it.

Hundreds of light years away, it means that it takes hundreds of years to transmit information back to Earth at the speed of light, in terms of time, this is really unreasonable, two hundred years ago human beings have not even made the first rocket, no, the problem of rocket propulsion fuel has not been solved, so it is impossible to set off at that time.

"That's the second concept I'm going to talk to you about today, spatial folding." Camille said calmly.

"This concept must be familiar to everyone, as early as a hundred years ago it was proved that space will be distorted in a state of strong gravity, just now I said, you should be able to see a big black hole at the edge of the world in that game world, that is, a hundred years ago, the Herschel Space Observatory discovered the supermassive black hole Sagittarius A type in the center of the Milky Way, with a calculated mass of about four million times that of the sun." "At the center of the line between the Earth and that world is the 'warp point' created by the black hole, or the point of spatial folding," Camille said. ”

"Wouldn't it be captured by the gravitational pull of the black hole when you pass through there?!" Mo Youlai asked.

Sagittarius type A, of course, he knows that this is one of the largest celestial bodies discovered by human beings in the last century, from the observation distance is the immediate proximity of the solar system, the universe is extremely dangerous, there is not enough energy for human beings to go deep into space just to send them to death, among them, being captured by gravity is one of the most terrible ways to die, with the distorting force of a black hole, any matter in this world can be crushed into nothingness in a moment.

"After calculation, the rate required to get rid of the gravitational pull of the black hole there is a relativistic speed of '0.8', which is 0.8 speed of light, and before passing there, the person was riding in the vehicle had already entered the speed of light, so it was not captured by gravity."

"Is that the signal using electromagnetic waves? With such a long-distance signal transmission, electromagnetic waves will not be affected by various rays in the universe, how to solve the problem of transmitting information?! ”

Camille shook his head at this moment and said helplessly, "I'm sorry...... This is confidential, and the secrecy level is 'top secret', and I have no right to disclose it....... Don't talk about this, I'm talking to you about this today, it's actually a crime, or it's not for ......."

She stopped, changed the subject, and continued, "Actually...... That's not the point, I'm here to talk to you today...... It's an interesting theory about my friend who seems to have discovered the phenomenon of 'time reversal' in that world. ”

！！！

hat？！！

Wu Mo twitched as if he had been stimulated by electricity, and the other three were also dumbfounded.

Time is a topic that has been debated in the scientific community for many, many years, from Einstein's connection between time and the speed of light to Schrödinger's cat to the later parallel world theory of time paradox, the butterfly effect, etc., but in the end, the answer given by the scientific community is: there is no solution, time cannot be reversed.

"Hehe, even the speed of light is not a constant value, and who can say for sure when it comes to time."

"It should be said that it is impossible for an object with mass, but quantum information is not necessarily, 12 years ago, after the success of the space string connection experiment, someone once made a small extended black hole in the Blanck laboratory, and then successfully sent the quantum entanglement information through the black hole to the supercomputer thirteen seconds ago with high energy, this thing is called the information transfer revolution, but the experiment was terminated......" The only one who had been sitting there The girl from the computer information department finally spoke.

This girl is the quietest, but she is the most important one among the students present today, after all, she is the winner of the first prize of the National Science and Technology Innovation Award, it is said that she is also very famous in Jinghua University, and she is basically already a student of 'internal determination'.

"The ability to send information to the past is a major revolution, using the principle of warping, where the strong gravitational pull of a black hole distorts space and also causes distortions similar to 'dimensions', and two different points in time also overlap under strong gravity, which can be caused by the fact that the information is penetrated with enough energy....... However, in practice, there is no significance in practical application, and the penetration of information at the warping point at the edge of the black hole will cause the phenomenon of 'attenuation', and after calculation, even a large amount of information of 50 trillion T, within 20 seconds of sending a signal, will decay to 0 or infinitely close to 0, so this research has no meaning. ”

.......

Camille was suddenly silent for a few seconds.

None of the people in the classroom spoke, and there was an eerie absolute silence for a few seconds.

Camille suddenly asked, "Kid, what's your name?!" ”

The girl stood up very respectfully and introduced herself, "Hello Professor Camille, my surname is Yin, Yin Yanbai, a student of the Department of Computer Science. ”

"Very good..... You're good..... It's not easy to have such insight at this age. Camille said.

To tell the truth, Camille herself is not disgusted with Chinese students, because there are still many outstanding people here, at least at the same age, they are not inferior or even far superior to some so-called European and American top students, but she has long heard that China has been heavy on politics and light on science since ancient times, and what is even more terrifying is that a scientific researcher in China actually has an administrative level division, and the president of the university is actually at the same level as the department-level cadre, which is unimaginable in the European League.

This is what Camille is most disgusted with, and with the thinking of the European Union, it is not an insult to academia to directly link science and politics? How can the nobility of scholarship be measured by power?! She is averse to politics, not to students.

She is very happy that the students she met today are very good, at least in terms of knowledge.

Especially this girl named Yin Yanbai, she has always been very quiet, but as soon as she opened her mouth, she was amazed, including Camille herself, who was also amazed by her.

It's just that she is still a little immature, although it is a piece of beautiful jade, she still needs to be patient and carve.

"Son, the quantum information you spoke of is still of quality, but we're ignoring it." Camille suddenly felt that she was right to be here today, she said, "We call a message signal with mass that can be transmitted stably at the speed of light 'medium wave', you know, the attenuation that occurs when the information penetrates is because the signal source you use to transmit the information itself has mass and the loss caused by friction when penetrating in an extremely gravitational environment, what if you really use a signal source without mass to transmit the signal?!" ”

"And this kind of signal source?!" Yin Yanbai's pair of eyes opened slightly, and asked with some surprise.

"Yes, this kind of signal source we call 'shortwave', specifically...... It's not convenient for me to disclose, it's also top secret. ”

She didn't say it, but there were huge waves in Yin Yanbai's heart.

Quantum entanglement encodes information to penetrate the gravitational field of the black hole because the mass of the quantum itself will wear out, so humans use this method to transmit information for a maximum of 20 seconds, and it is still incomplete information.

And if there really is a so-called quality-free source of information, it will be different...... There is no decay when it penetrates the gravitational field, and theoretically, the time that can be transmitted is infinite......

Camille gave a spooky smile.

"Hey..... Children, let me tell you another message, although short-wave can transmit information, short-wave cannot be captured by any electronic device, that is, with the current equipment of human beings, it cannot capture any short-wave information. ”

........

Everyone didn't understand the meaning of Camille's words for a long time, and so did Wu Mo, but many years later, Wu Mo, who had experienced everything, remembered Camille's words today, and finally broke out in a cold sweat. When he summed up all the hidden information in this sentence, he really thought about it carefully.

1. Short waves can cross infinite lengths of time and space through warp points.

2. Short waves cannot be captured and detected by any electronic equipment and instruments

So to conclude 1: Perhaps in the future, countless future beings have sent short-wave messages to the past, but no one has been able to capture them so far.

Proceed to conclusion 2: We may be surrounded by countless short-wave messages from the future today, but we cannot perceive them.

It's just that at this moment, at this moment, he hasn't realized the true meaning of Camille's words.

Because at the time, he felt that information that could not be interpreted had no value.
