Three bodies

Ever since she entered the Red Bank Base, Ye Wenjie never expected to go out. After learning the real purpose of the Red Bank Project (this top-secret information was unknown to many middle-level cadres in the base), she also cut off the spiritual connection with the outside world. , just buried in work.After that, she got more deeply involved in the technical core of the Red Coast system, and began to undertake relatively important research topics.Lei Zhicheng has always been worried about Yang Weining's trust in Ye Wenjie, but he is still willing to hand over important projects to Ye Wenjie - as Ye Wenjie, she has no rights to her research results; and in the base, only Lei Zhicheng had a background in astrophysics, and was a rare intellectual political commissar at the time. In this way, Ye Wenjie's achievements and papers were all taken up by him in the end, making him a typical red and professional political cadre in the army.

The original reason why Ye Wenjie entered the Red Bank base was the paper she published in the "Acta Astronomical Journal" when she was a graduate student, trying to establish a mathematical model of the sun.In fact, compared with the earth, the sun is a simpler physical system. It is only composed of two very simple elements, hydrogen and helium. Although its physical process is violent, it is very simple. It is just the fusion of hydrogen to helium. Therefore, It is possible to build a mathematical model to describe the sun more accurately.That paper was originally a very basic thing, but Yang Weining and Lei Zhicheng saw the hope of solving a technical problem of the Red Bank monitoring system.

The issue of Riling interference has always plagued Red Bank's monitoring operations.This term is borrowed from the communication satellite technology that has just emerged. When the earth, satellite and the sun are in the same straight line, the satellite that the ground receiving antenna is aimed at is the sun as the background, and the sun is a huge electromagnetic emission source. At this time, the satellite microwaves received by the ground will be strongly interfered by the electromagnetic radiation of the sun. This problem cannot be solved until the 21st century.The Sun Transit interference experienced by Red Coast is similar, except that the source of interference (the sun) is located between the transmitter (outer space) and the receiver.Compared with communication satellites, the sun transit interference of Red Bank occurred more frequently and more severely.The actual Red Coast system has shrunk a lot compared to the original design, and the monitoring and transmitting systems share the same antenna, which makes the time for monitoring more precious, and interference from the sun has become a serious problem.

The idea of ​​Yang Weining and Lei Zhicheng is very simple: find out the spectrum rules and characteristics of the electromagnetic waves emitted by the sun in the monitoring band, and use digital filtering to filter them out, so as to eliminate interference.Both of them are technical experts, which is rare in this era when laymen lead experts.But Yang Weining is not an astrophysics major, and Lei Zhicheng is a political worker, so it is impossible to know too deeply professionally.In fact, the stability of solar electromagnetic radiation is limited to the near-ultraviolet to mid-infrared bands including visible light, and its radiation is volatile in other bands.Ye Wenjie wisely clarified one point in the first research report: during periods of violent solar explosive activities such as sunspots, flares, and coronal mass ejections, the interference of the sun transit cannot be ruled out.Therefore, the research object is limited to the electromagnetic radiation in the red bank monitoring band when the sun is in normal activity.

The research conditions in the base were good, and the reference room could transfer relatively complete foreign language materials according to the subject content, as well as timely European and American academic journals, which was not an easy task at that time.Ye Wenjie can also contact the two solar scientific research units of the Chinese Academy of Sciences through the military line, and obtain their real-time observation data by fax.

Ye Wenjie's research lasted for half a year, with no hope of success in sight.She soon discovered that within the frequency range of Red Bank's observations, the sun's radiation was unpredictable.Through the analysis of a large amount of observation data, Ye Wenjie discovered the mystery that confuses her: sometimes, when the above-mentioned radiation in a certain frequency band changes suddenly, the activities on the surface of the sun are calm as usual. Thousands of observation data have confirmed this point.This is very puzzling to her.It is impossible for short-wave and microwave-frequency radiation to penetrate hundreds of thousands of kilometers of the sun’s surface and come from the core of the sun. It can only be produced by activities on the sun’s surface. When a sudden change occurs, this kind of activity should be able to be observed. If the sun does not have corresponding disturbances, What caused the mutation in this narrow frequency band?The more she thought about it, the more mysterious it became.

When the research came to an end, Ye Wenjie decided to give up.She admitted in her final report that she was powerless.This matter should be easier to explain. Similar studies commissioned by the military to several units of the Chinese Academy of Sciences and universities all ended in failure. Yang Weining just wanted to use Ye Wenjie's extraordinary talent to try again.Lei Zhicheng's real idea was even simpler, he only wanted Ye Wenjie's thesis.This research is very theoretical, and it can better show his level and level.Now, the wave of madness in society has gradually subsided, and the requirements for cadres have also changed. People like him who are politically mature and academically accomplished are scarce, and of course they have a bright future.As for whether the Riling issue can be resolved, that's not what he's most concerned about.

But Ye Wenjie did not submit the report in the end. She thought that if the research was over, the collection of data and subscriptions to foreign journals for this subject by the base reference room would stop, and she would never have access to such a wealth of astrophysics data. up.Therefore, she continued the research nominally, but actually devoted herself to developing her own mathematical model of the sun.

That night, as usual, Ye Wenjie was alone in the cold reading room of the reference room, and a pile of periodicals and documents were spread out on the long table in front of her.After completing a cumbersome matrix calculation, she sighed and picked up the latest issue of "Astrophysics" magazine with her frozen hands. Just as a rest, she flipped through it casually. A paper on the study of Jupiter caught her attention. Note that the abstract of the paper is as follows:
In the last issue of the newsletter "New Strong Emission Sources in the Solar System", Dr. Harry Bidson of the Mount Wilson Observatory released a batch of data about his gravitational attraction to Jupiter on June 6 and July 12. During the resulting rotation wobble observations, strong electromagnetic radiation emitted by Jupiter itself was unexpectedly detected twice, each lasting 7 seconds and 2 seconds respectively. This batch of data recorded the frequency range and other parameters of the radiation.During the radio bursts, certain changes in the state of the Great Red Spot on Jupiter's surface were observed and described by Petersen in the text message.Jupiter's radio bursts have aroused great interest in planetary academia. G. Mackenzie's article published in this issue believes that this is a sign of the initiation of nuclear fusion inside Jupiter; the next issue will publish an article by Inoue Yunshi, which will attribute Jupiter's radio bursts for a more complex mechanism: the motion of the inner metallic hydrogen plates, and gives a complete mathematical description.

Ye Wenjie clearly remembered these two dates and times. At that time, the Hongan monitoring system was strongly disturbed by the sun.She checked the operation log and confirmed her memory, but the solar transit interference from the sun arrived at the earth 42 minutes and 42 seconds later than the electromagnetic radiation from Jupiter. This crucial 42 minutes and [-] seconds!Ye Wenjie suppressed her violent heartbeat, and asked the relevant personnel in the reference room to contact the National Astronomical Observatory, and obtained the position coordinates of Jupiter and the Earth at those two times.She drew a large triangle on the blackboard, the three vertices were the sun, the earth and Jupiter, and she marked the distance on the three sides, and marked two arrival times at the vertices of the earth.From the distance from Jupiter to the earth, it is easy to calculate the time it takes for electromagnetic radiation to reach the earth directly from Jupiter. She then calculated the time for electromagnetic radiation to reach the sun from Jupiter, and then the time from the sun to the earth. The difference between the two is exactly [-] minutes and [-] seconds !

Ye Wenjie dug out the mathematical model of the sun's structure that he had created before, trying to find some clues in theory.Her eyes quickly locked on something called "energy mirror" in the solar radiation layer.The energy emitted from the solar nuclear reaction area is initially emitted in the form of high-energy gamma rays. The radiation area realizes energy transfer by absorbing and re-emitting these high-energy particles. The sun may take 1000 years), high-energy gamma rays gradually become visible light and other forms of radiation through X-rays, extreme ultraviolet rays, and ultraviolet rays.These are things that have long been established in solar research.A new result produced by Ye Wenjie's mathematical model is: there are many obvious interfaces between the conversion of these different frequency radiations, and the radiation area goes from the inside to the outside, and every time an interface is crossed, the radiation frequency will obviously drop by one level, which is the same as The traditional view is that the frequency of the radiation area is gradually different.Calculations showed that such an interface would reflect radiation back from the low-frequency side, so she came up with a name for it.

Ye Wenjie began to carefully study this erratic film suspended in the solar plasma ocean. She discovered that this kind of thing that can only appear in the high-energy ocean inside the star has many wonderful properties, the most incredible of which is Its "gain reflection" properties, which seem to be relevant to the mystery of the sun's electromagnetic radiation.But this characteristic is too outlandish and difficult to prove. Ye Wenjie herself can hardly believe it, and it is more likely to be caused by some misleading in the dizzyingly complex calculations.

Now, Ye Wenjie has preliminarily confirmed her conjecture about the gain reflection of the solar energy mirror: the energy mirror does not simply reflect the electromagnetic radiation at the low frequency side, but amplifies it!Those mysterious mutations in the narrow frequency band observed before are actually the result of the radiation from the universe being amplified, so no corresponding disturbance can be observed on the surface of the sun.

It is very likely that this time, the sun emits the electromagnetic radiation after receiving Jupiter's electromagnetic radiation, but the intensity has increased by nearly 42 million times!The earth received two radiations before and after amplification with a time difference of [-] minutes and [-] seconds.

The sun is a radio amplifier!

Here comes a question: the sun is receiving electromagnetic radiation from space all the time, including radio waves overflowing from the earth, why does it only amplify a part of it?The reason is obvious: in addition to the selection of the reflection frequency by the energy mirror, it is mainly the shielding effect of the sun's troposphere.Above the radiative layer is the convective, boiling surface, the sun's outermost liquid layer.Radio waves from space first have to penetrate the troposphere to reach the energy mirror of the radiation layer, and then be amplified and reflected.This requires the incoming radio waves to exceed a threshold in power. Most radio emissions on Earth are far below this threshold, but Jupiter’s electromagnetic radiation exceeds——

Red Bank's maximum transmit power also exceeds this threshold!
The problem of the sun’s transit interference remains unresolved, but another exciting possibility has emerged: Humans could use the sun as a super antenna, through which to send radio waves into the universe, which are sent out with stellar energy. Its power is hundreds of millions of times greater than all the transmitting power that can be used on the earth.

It is possible for the earth civilization to carry out the launch of Type II civilization energy level!

In the next step, it is necessary to compare the waveforms of the two Jupiter electromagnetic radiations with the waveforms of the disturbance of the Sun Transit by Red Bank. If they match, this conjecture will be further confirmed.

Ye Wenjie made a request to the leader to contact Harry Biederson to obtain the waveform records of the two Jupiter electromagnetic radiations.This is not an easy task, the channel is hard to find, and there are many departments to go through the formalities, if there is any confusion, it will be suspected of connecting with foreign countries, Ye Wenjie had to wait.

But there's a more direct way to confirm that: the Red Coast Transmitter system beams directly into the sun at a power above that threshold.

Ye Wenjie found the leader and made this request, but she didn't dare to express her thoughts directly. It was too mysterious and would definitely be rejected. She just said that this was an experiment for solar research, and that the Red Coast launch system was used as a test for the sun. The detection radar, by receiving echoes to analyze some information reflecting the sun's electromagnetic radiation.Both Lei Zhicheng and Yang Weining have deep technical backgrounds, and it is not easy to deceive them, but the experiment Ye Wenjie mentioned did have precedents in Western solar research. Radar detection of terrestrial planets is technically simpler.

"Ye Wenjie, you are getting more and more out of line. You can do your research theoretically. Is it necessary to make such a big move?" Lei Zhicheng shook his head and said.

"Political commissar, there may be a major discovery. The experiment is necessary, just this time, okay?" Ye Wenjie begged bitterly.

Yang Weining said: "Commissioner Lei, why don't we just do it once? There seems to be no major difficulty in the operation. The echo needs to be sent back after the launch..."

"Ten minutes." Lei Zhicheng said.

"This gives the Red Coast system just enough time to switch to the receiving state."

Lei Zhicheng shook his head again, "I know it's nothing technically and in terms of workload, but you... oh, Mr. Yang, what's missing in your mind is this string - sending super intense radio waves to the red sun, Have you ever thought about the political implications of this experiment?"

Yang Weining and Ye Wenjie were dumbfounded for a moment, they didn't feel that the reason was absurd, on the contrary, they were afraid because they didn't think of it.At that time, the political illustration of everything had reached an extremely absurd level. Lei Zhicheng had to carefully review the research report submitted by Ye Wenjie, and repeatedly revised the technical terms about the sun, such as "sunspot" and so on. Words cannot appear.Of course, there can be a thousand positive explanations for the experiment of sending super-powerful radio waves to the sun, but as long as there is one negative explanation, someone may face disaster.Lei Zhicheng's reason for refusing the experiment is indeed impossible to be overturned.

Ye Wenjie didn't give up. In fact, as long as she didn't take too much risk, it was easy to accomplish this.The launcher of the Red Coast launch system is an ultra-high-power device, all using domestic components produced during the "Cultural Revolution". Due to the poor quality and high failure rate, it has to be overhauled every fifteenth launch. After the overhaul is completed, a routine test run is required. There are very few people participating in this kind of launch, and the target and other launch parameters are relatively random.

During one shift, Ye Wenjie was assigned to conduct a test after routine maintenance. Since the test launch saved a lot of operations, there were only five people present besides Ye Wenjie, three of whom were operators who knew little about the principles of the equipment, and the other A technician and an engineer were exhausted and absent-minded after two days of overhaul.Ye Wenjie first set the transmission power to just exceed the theoretical threshold of solar gain reflection (this is already the maximum power of the Red Coast transmission system), set the frequency to the frequency most likely to be amplified by the energy mirror, and tested the mechanical performance of the antenna as Name, aim it at the sun that has been obliquely hanging in the western sky, and the content of the launch is still the same as every regular launch.

It was a sunny afternoon in the autumn of 1971. Afterwards, Ye Wenjie recalled that moment many times. She didn't feel any special feeling, but was anxious, hoping that the launch would be completed soon. On the one hand, she was afraid that the colleagues present would find out. However, it is not normal to carry out the launch experiment with the maximum power of the lossy components. At the same time, the positioning equipment of the Red Coast launch system is not designed to aim at the sun. Bad trouble will be big.The sun was slowly setting in the western sky, and Ye Wenjie had to track it manually. At this time, the Red Bank antenna was slowly turning towards the setting sun like a huge sunflower.She was drenched in sweat when the red light came on for the completion of the launch.Turning his head, he saw that three operators were shutting down the equipment one by one according to the manual on the console, the engineer was drinking water in a corner of the control room, and the technician was leaning on the long chair and fell asleep.No matter how later historians and writers described it, the real situation at that time was so ordinary.

As soon as the launch was completed, Ye Wenjie rushed out of the control room, ran into Yang Weining's office, and gasped, "Quick, let the base station receive on 12000 MHz!"

"What are you collecting?" Chief Engineer Yang looked at Ye Wenjie whose hair was sticking to his face with sweat in amazement. Compared with the highly sensitive Red Bank receiving system, the conventional military radio station used by the base to communicate with the outside world was just a toy.

"Maybe we can receive something, the Red Coast system doesn't have time to switch to the receiving state!" Ye Wenjie said.Under normal circumstances, it only takes more than ten minutes for the warm-up and switching of the Red Coast receiving system, but now the receiving system is also undergoing maintenance, and many modules have not been assembled after disassembly, so they cannot be operated in a short period of time.

Yang Weining looked at Ye Wenjie for a few seconds, picked up the phone, and ordered the confidential communication room to do what Ye Wenjie said. "The accuracy of that radio station is probably only able to receive signals from aliens on the moon."

"The signal comes from the sun." Ye Wenjie said.Outside the window, the edge of the sun was approaching the top of the mountain in the sky, blood red.

"Did you use the Red Coast system to send a signal to the sun?" Yang Weining asked nervously.

Ye Wenjie nodded.

"Don't tell others about this, it's not an example, it's definitely not an example!" Yang Weining looked back at the door vigilantly and said.

Ye Wenjie nodded again.

"What's the point of this? The echo must be extremely weak, far beyond the reception capabilities of conventional radio stations."

"No, if my guess is correct, I will receive an extremely strong echo, so...unimaginably strong, as long as the transmission power exceeds a threshold, the sun...can amplify the radio waves by billions of times!"

Yang Weining looked at Ye Wenjie strangely again, but the latter fell silent.The two waited quietly. Yang Weining could clearly hear Ye Wenjie's breathing and heartbeat. He didn't pay much attention to what she said just now. It was just that the feelings that had been buried for so many years came to his heart again, but he could only control himself and wait. with.Twenty minutes later, Yang Weining picked up the phone, wanted to call the communication room, and asked a few simple questions.

"I didn't receive anything." Yang Weining put down the phone and said.

Ye Wenjie heaved a sigh of relief, and nodded her head after a long time.

"The American astronomer replied." Yang Weining took out a thick envelope and handed it to Ye Wenjie, which was covered with customs stamps.Ye Wenjie couldn't wait to open the envelope, and first glanced at Harry Pederson's letter. The letter said that he did not expect that there were colleagues in China who studied planetary electromagnetism, and hoped to contact and cooperate more.What he sent were two stacks of paper, which completely recorded the waveforms of the two electromagnetic radiations from Jupiter. The waveforms were obviously copied from long strips of signal recording paper, and they had to be aligned. At this time, the Chinese were still Most have never seen a copier.Ye Wenjie lined up dozens of sheets of copy paper in two rows on the floor. Halfway through the row, she had given up any hope. She was too familiar with the waveforms of the two solar eclipses, and they definitely didn't match up with these two.

Ye Wenjie slowly picked up the two rows of copy paper from the ground.Yang Weining knelt down to help her tidy up. When he handed over a dozen papers in his hand to the girl he loved deeply, he saw her shaking her head and smiling. That smile was so sad that it made his heart tremble.

"What?" he asked softly, not realizing that he had never spoken so softly to her before.

"It's nothing, it was just a dream, I just woke up." After Ye Wenjie finished speaking, she smiled again, and walked out of the office with the pile of copy paper and envelopes in her arms.She returned to her residence, took her lunch box and went to the cafeteria, only to find that there were only steamed buns and pickles left.The people in the cafeteria angrily told her that the door was about to close, so she had no choice but to walk out with her lunch box, walked to the cliff, sat on the grass and ate cold steamed buns.

At this time, the sun had already set, and Daxing'an Mountains looked like a piece of gray, just like Ye Wenjie's life. In this gray, the dream was especially brilliant.But dreams will always wake up soon, just like the sun, although it will rise, but it has no new hope.At this time, Ye Wenjie suddenly saw that the rest of her life was only endless gray.With tears in her eyes, she smiled again and continued to eat the cold steamed buns.

Ye Wenjie didn't know that at this moment, the first audible cry from the earth's civilization into space had already centered on the sun and flew to the entire universe at the speed of light.The powerful radio waves with stellar power, like a majestic ocean tide, have crossed the orbit of Jupiter at this time.

At this time, on the 12000 MHz band, the sun is the brightest star in the Milky Way.
