Five months later, the Chinese Academy of Sciences Particle Astrophysics Laboratory celebrated its first anniversary at Sias International College.
Because of Pan Tianyi's extraordinary computer talent and outstanding study abroad experience, he was recommended by the leaders of SIAS to continue his graduate studies at the Chinese Academy of Sciences. Now, the mentor who leads him is Professor Yang Yitong, a man who was murdered by hostile forces outside the country a few years ago but was rescued by him.
In a dark laboratory, Pantian connected a Pierce-type electron gun to a voltage and began an electron double-slit interference experiment.
An electron gun emits a steady stream of electrons, passing through two slits A and B. The electrons arrive at the detection screen one after another, accumulating messy bright spot marks like stars, and then producing several more obvious streaks. interference fringes, with the middle fringes being the brightest.
"These diffraction patterns you see illustrate the wave-particle duality of electrons."
Professor Yang walked in from the door of the laboratory and saw Pan Tianyi concentrating on the double-slit interference experiment. He commented with some surprise: "The principle of quantum superposition implies two very common features of quantum theory. One The first is uncertainty. There is no clear physical image in the quantum world. The second is the superposition state. When consciousness participates in the observation, the measurement results of the quantum world will have a probabilistic superposition state."
"The electron double-slit interference experiment is horrifying. In other words, human subjective consciousness affects the movement of microscopic particles."
Pan Tianyi listened to Professor Yang's footsteps and recorded the alternating light and dark interference fringes on the detection screen. Then, he installed a camera lens in the instrument box to determine which slit the electrons passed through to cause interference.
When an indivisible single electron passes through the instrument, through which slit does it pass to reach the detection screen?
After a series of experimental statistics, it was shown that the relative probability of a single electron passing through the two slits was half, but the interference fringes on the detection screen also disappeared.
Professor Yang looked at the experimental results, frowned and said: "Electronic double-slit interference is like a shy girl, not letting you see it at all. It seems to have consciousness and eyes. As long as you are looking at her, she can notice it and will show Different results.”
"Indeed, Professor Yang!"
Pan Tianyi was originally curious about the phenomenon of quantum superposition and wanted to study the experiment alone, but Professor Yang came in and discovered it, but he did not blame himself for this.
"Science is long and tortuous. Today's ignorance and doubts will definitely have many answers in the future!"
Professor Yang Yitong looked at Pan Tianyi's face full of doubts, and comforted: "This afternoon we are going to attend the Xiangshan Conference with cutting-edge scientific planning to discuss the conceptual planning of the CEPC collider. Maybe we will meet my old friend A good friend and an authoritative expert in the field of quantum communications."
"Are you attending the High Energy Circular Electron Positron Collider meeting?" Pantian asked with a look of confusion on his face. "An authoritative expert, who could it be?"
"He is Academician Pan Yun, and you can learn a lot of theoretical knowledge about quantum entanglement from him."
Professor Yang looked at Pan Tianyi and thought for a short time, and then said meaningfully: "Studying the hadron collider is the core content of this meeting. The main discussion is the conceptual design and optional construction location of the CEPC accelerator, which is estimated to be available by 2030." It was officially completed and put into scientific research use.”
"At that time, a stream of high-energy particles close to the speed of light will be injected into the collision ring, causing particle collisions to produce Higgs bosons or other unknown particles." Pan Tianyi showed curiosity on his face.
"Maybe there are more unknown discoveries!" Under Professor Yang's silver-rimmed glasses, a pair of brighter eyes flashed.
...
At the Xinglong Observatory of the HB Provincial Observatory, a huge white building points obliquely at the starry sky. This is the newly built Guo Shoujing Telescope, LAMOST.
"The stars in the sky are dazzling, and only in this quiet night can we observe the joy of the depths of the universe with the help of a survey telescope."
A young researcher named Liang Zhaokun said to Nan Boming, a scientist from the Sky Eye Project, with his back against the white building exterior wall.
At this time, Nan Lao sat on a stone on the ground, lit a cigarette, and was silent for a while. "This is the most authoritative and high-yield spectroscopic survey telescope independently designed by our country. It can realize automatic observation and data processing." information capabilities.”
Above the eastern horizon, the Orion constellation appears. Several meteors seemed to fly towards the earth from there, rushing into the atmosphere and disappearing.
"Yes, Professor Nan!" Liang Zhaokun then found a stone on the ground and sat next to Nan Boming.
"Through the telescope's spectral detector monitoring, it was discovered that a large number of abnormal band celestial rays were discovered near the Orion spiral arm of the Milky Way. According to the analysis of massive celestial body spectral data, a large number of new stars are likely to have been born in the nebula near Orion. These stars In different evolutionary sequences, some of them evolved into neutron stars, while others merged into larger blue supergiants..."
"And these large numbers of moving star groups are likely to be affected by the space density waves of the Orion spiral arm. They follow the nebula with a diameter of thousands of light years and continue to spread away from the outer reaches of the Orion spiral arm."
At this time, Professor Nan Boming pondered and thought over and over again, recalling the study of spectral data last night. He found that a large number of stellar objects had red shifts and blue shifts. Finally, he expressed his opinion: "These outwardly diffusing The Moving Star Group contains a total of 206 stars and a small number of unknown celestial bodies. However, their trajectories are not exactly the same. Most of their stars are rapidly rushing towards the Sagittarius spiral arm. What is incredible is that some of them are rushing towards the Sagittarius spiral arm. During the journey, they disappeared from the Milky Way. In addition, a small number of celestial bodies and comets appeared passing through the solar system and flying towards the earth."
At this time, a late autumn chill was blowing in the mountainous area, and another meteor shower flashed across the starry sky.
A voice broke the silence between the two. A young, tall and thin man ran over with excitement on his face: "Professor Nan, Dr. Liang! We received a response from the ESA Astronomical Observatory. They based on the celestial spectrum provided by our observatory. Data, monitoring and verifying the moving star cluster near the Orion Nebula in the Milky Way, I am deeply shocked and recognized by the observation data of our observatory!"
This young man is Yang Zhou. Regardless of the objections of Professor Yang Yitong, he privately applied to the school to graduate early. Now he is following Professor Nan Boming to engage in astronomical research on cosmic observation.
"This young man is as stubborn and courageous as his father. This is what I highly value about him!"
Nan Boming smiled at colleague Liang Zhaokun, and then the two stood up and returned to the spectral data analysis room of the observatory.
The next morning, there was a meeting in Xiangshan, the imperial capital.
After the meeting, Pan Tianyi and Professor Yang were walking in a Chinese-style corridor. A middle-aged man walked across from them, wearing a gray suit and black-rimmed glasses.
"Hello, Academician Yang! Building accelerator experimental devices is the development trend of future particle physics research."
"Nice to meet you, Academician Pan Yun! Quantum communication will bring about earth-shaking changes in human life in the future." Yang Yitong saw his old friends and stepped forward to greet him.
Pan Yun looked at the young man next to Yang Yitong with doubtful eyes, appearing extremely surprised. He had never seen such an outstanding student win the favor of Professor Yang. Professor Yang saw this, smiled slightly at Pan Yun, pointed his palm to Pan Tianyi and introduced:
"This is my student Pan Tianyi. Maybe you have a common topic about quantum mechanics! Just yesterday, my student studied the wave-particle duality of microscopic particles alone in the laboratory. "
At this time, Pan Tianyi showed surprise for the first time, and then greeted Academician Pan Yun with full respect: "I am very happy to meet Academician Pan. I have admired his name for a long time! I have a question to ask you. Is it okay?"
Pan Yun looked at Pan Tianyi with appreciative eyes, his handsome and delicate face shining with a pair of clear and energetic eyes. Faintly, his heart felt the fluctuations coming from the depths of his spirit, as if a quantum cloud was projecting an unpredictable flow of information into his heart.
He was silent for a long time, and then showed a friendly smile: "I only know the problems in the field of quantum communication. If you raise a problem of high-energy particle collision, it will be difficult for me!"
"Does quantum entanglement also exist from the ground to distant space?" Pan Tianyi seemed to ask specifically.
"Of course it exists. If a quantum communication satellite is launched into deep space, the receiving station on the ground can obtain safe and reliable information through the quantum key."
"Oh, that's it... Maybe there is an entangled relationship between people and time and space..." Pan Tianyi stood there with a blank look on his face, muttering to himself in a low voice. With. At this time, Professor Yang and Academician Pan burst out laughing, looking at the maple forests all over the mountains and fields, dyeing the sky red like fire. ,
After a burst of laughter, a mysterious man in sunglasses walked out of the pavilion next door. He looked at the peaceful and sparse crowd around him, and cautiously walked up to Professor Yang and Pan Yun:
"Hello! I am Secretary Yan of the National Supernatural Bureau of the Second Expeditionary Base. According to the instructions of the Central Fire Project, I will lead you to the Second Expeditionary Base to perform a special mission..."
Two days later, two Chinese Aegis ships set off from the Bohai Sea, passed through the East China Sea, and docked at the Zhoushan Military Port of the Second Expedition Base. A group of scientific workers secretly docked with the military personnel to rest.
Pan Tianyi followed Secretary Yan in a military off-road vehicle, passed through several buildings in the valley, and arrived at the mountainside a few kilometers away. A huge natural cave appeared in front of them. There were several sculptures carved on the top of the cave. A big red letter: Nanjing Military Region 8587 Armor Project.
Below the cave, there were several familiar faces standing. As soon as Pan Tian got out of the car, he saw a figure wearing green casual clothes, with a slender face full of proud expectations.
"Big! Big!"
"Tianyi, you are so proud of our family!"
When the father saw his son appearing in front of him, Panyu was so excited that he slapped his back with her hand. "I haven't seen you for a year, your shoulders have become much stronger!"
Pantian showed joy, looked at the crowd around him, and smiled shyly.
My father works here, and his mental state has regained a new lease of life. He no longer has the depression of losing his mother in the past. In this regard, Pan Tianyi was full of gratitude to the comrades standing around, especially Gao Jianhua, who was standing next to his father. The reason why his father could work here was that Director Gao had spent a lot of thought on this aspect.
"Pan Tianyi! Pan Tianyi!"
A sweet and ethereal girl voice came from Pantian's side, and Han Yuting was seen walking over from a distance accompanied by her mother. When she learned from her father Yan Ming that her boyfriend was coming to the base, she came to the tank camp repair center early. After Pan Tianyi finished talking to his father, she walked over quickly like a white cloud and threw herself tightly into Pan Tianyi's arms. Under the gaze of everyone, her fair face revealed a blush that was difficult to conceal.
Pan Tianyi hugged Han Yuting and remained silent for a long time without showing any shyness. He simply regarded the people around him as transparent air.
"Look at this girl, she has been too pampered since she was a child." Han Yun looked at Yan Ming beside him with an embarrassed look, but Yan Ming showed a cold look.
"Haha..." A burst of laughter came from Gao Jianhua, and he then smiled and said, "Today's young people value love more than anything else. I think I will be the go-between to help you. Let's tie the rope and complete the marriage..."
After a while of envy, everyone left and returned to the cave, talking about various problems they encountered at work.
Only Pan Tianyi and Han Yuting were left at the scene. They smiled at each other, then held hands and walked into this huge natural cave with curiosity.
The space of the cave is open and clear, separated by dozens of independent rooms. Going inside is a military secret space, and Pan Tianyi's father usually works here, drawing complex dynamic drawings and splicing certain parts of armored vehicles. parts...
