August 15, 1977, Columbus, Ohio, USA.

On the campus of the state university, a large radio telescope is mounted on the top of a tall building. On this day, while receiving radio signals from the depths of space on a daily basis, radio telescopes suddenly recorded an unusual signal. The signal lasted about 72 seconds, was extremely strong, far overshadowing all other background signals in the entire sky at the time, and the signal was very narrow, much like an artificial signal.

NASA immediately organized experts to decipher this signal, and after deciphering it, the content of the signal was translated into "WOW", which is the famous "WOW" signal.

Scientists further confirmed that this signal came from deep space 200 light-years away from the earth, but the scientific community was at a loss as to what the mysterious signal expressed, and the mysterious signal has also become an unsolved case in the history of the world's aerospace industry.

March 14, 2018, London, England, Hawkin's private residence.

In the early hours of that morning, Hawkin, who is known as the most knowledgeable about space life and parallel worlds on Earth, ushered in the last moments of his life. After saying goodnight to his family, he waited for the photographer to take one last photo of him. He was 76 years old, and at the age of 21 he suffered from amyotrophic lateral sclerosis, paralyzed and unable to speak, and doctors once asserted that he would not live to be 25 years old.

By this day, Hockin's nerves throughout his body were gradually necrotic, and only a small active muscle under his eyes was still active. This small muscle is implanted with a sensor chip, which allows him to control the cursor and let the cursor stay on the letters of the corresponding computer keyboard to "say" what he wants to say. In the past two weeks, Hawkin has presented his final paper in this way, proposing a mathematical approach to space exploration in search of evidence of a "multiverse", predicting that the universe will disappear into darkness when all stars lose energy.

"Can you give me one more word about what you want to say to the world?"

When it was time to leave after the photo shoot, the photographer finally couldn't hold back and asked Hawkin one last question.

"I'm sorry, Mr. Photographer, Mr. Ho-Kim is already very tired, I'm afraid he won't be able to finish it. In addition, the muscles under his eyes are also atrophiing, and he has been making mistakes a lot lately, and he may not be able to do it. Hokin's personal nurse preemptively said.

The photographer sighed helplessly and was about to leave when he suddenly heard the sound of the cursor flashing on the screen. Both he and the nurse stopped, and saw Hawkin directing the cursor to move with the small muscle under his eye, and finally resting on W.

The nurse said, "I'm sorry, Mr. Ho-King's typing has been often out of control lately, and sometimes the words typed out are meaningless. ”

However, the cursor moved again.

The second time, stay on the o.

After a while, the cursor moved again, and finally landed on the w.

WOW again!

January 14, 2020, Pingtang County, Guizhou Province, China.

The large radio telescope, known as China's Sky Eye, is located deep in the mountains of China. China's Sky Eye has the world's largest single-aperture aperture, with a total area the size of 30 football fields, and its sensitivity is more than 2.5 times that of the world's second largest single-aperture radio telescope. Since the trial operation, 146 high-quality pulsar candidates have been detected, and the maximum detection distance has reached 16,000 light-years.

This day is the third day that Tianyan has successfully passed the national acceptance and officially opened for operation, and astronomy enthusiasts from all over the country have flocked to the viewing platform.

The researchers in charge of monitoring sit in front of the screen as usual, and the Sky Eye detects that the space signal will be transmitted to the screen at the right time.

Drip, drip!

At 10 o'clock in the morning, a sharp and rapid sound suddenly came from the monitoring room, and the computer cursor flashed rapidly, and a series of wavy curves appeared on the screen. The amplitude of the curve greatly exceeds the fluctuations caused by the usual signal, and the peaks and troughs once reach the upper and lower ends of the screen interface.

The signal came very suddenly, and after 72 seconds, it came to an abrupt halt, and the signal map on the screen returned to normal.

At the same time of the unexpected change, the tourists on the viewing platform were like under a spell, frozen in place, without exception, their eyes were dull, their expressions were blank, and they maintained the posture of the previous moment. Immediately, the light of the Sky Eye was flourishing, and 4480 reflective surfaces reflected 4480 beams, the beams flickered, and finally converged into a point, forming a sphere of light above the Sky Eye. The sphere of light vibrated violently in the air, from large to small, and finally became the size of a ping-pong ball.

Shout!

The sphere of light sprang out like a meteor and disappeared in the northwest direction in an instant.

The reflected beam disappeared, the surroundings returned to calm, and the visitors on the observation deck were like being pressed the pause button and then the play button, resuming their normal demeanor and movements, and continuing to take pictures and post on Moments. What they didn't know was that time had slipped away from them for an extra 72 seconds.

Three days later, a signal decipherment research team composed of multidisciplinary experts concluded that the strange signal received by the Sky Eye could be translated into a Chinese interjection, "Wow", which in English is "WOW"!

January 18, 2020, Sanxingdui Museum, Guanghan, Sichuan Province, China.

It was a weekend, close to the Chinese New Year, and there were a lot fewer tourists than usual.

"The history of Sanxingdui can be traced back to 5000 to 3000 years ago, Sanxingdui civilization is a relatively independent civilization system, from the unearthed bronze production process, earlier than the known Central Plains civilization, some scholars believe that Sanxingdui civilization is the most direct continuation of civilization of the Chinese ancestors, from the unearthed cultural relics and "Classic of Mountains and Seas" and many other ancient records, can find clues. "The narrator is a handsome young man who is speaking fluent English to a group of foreign tourists," ...... Everyone, this way, please. ”

Sanxingdui Museum has a total of six units of theme exhibition halls, after browsing the first five, the docent will guide visitors to the last unit, that is, "Tongtian Tree - a symbol of the wisdom and spirit of the ancient Shu people".

"The remnant height of this sacred tree is 396 centimeters, and the lower part of the tree is a circular base...... In the middle of the branches of the sacred tree protrudes short branches, and on the short branches there are small circles and flower buds with hollow patterns, and on each bud there is a small bird with its head and tail up, and there are nine birds in all......"

"Actually, it should be ten birds. In the group of foreign tourists, a young man with an oriental face said suddenly.

"Oh?" everyone stared at the man.

"Oh, sorry. I'm a photographer who writes for a travel magazine and know a little bit about the Bronze Sacred Tree. The man pushed his glasses slightly embarrassed, "The Classic of Mountains and Seas" contains: "There is Fusang in the Tang Valley, and the bath for ten days is in the north of Moya." In the water, there is a big tree, which is on the lower branch for nine days, and the upper branch for one day. "The sacred tree is Fusang, and there are ten suns living on the tree, and it is said that the three-legged black is carried on duty in turn every day, and the sun sets in the east and the sun sets in the west, so there should be ten birds on this tree, as for why there are only nine instead of the legendary ten, it is probably damaged and not found. ”

As if realizing that he had said too much, the man quickly apologized again, "Sorry to disturb you." ”

"Not much, thank you. The docent didn't care, and led the tourists on.

The young man didn't follow any further, and stayed in front of the sacred tree, thinking about taking a few pictures of the sacred tree for the magazine. He used his professional eye to lock on the best shooting angle, held up the camera, and fine-tuned the focus until the sacred tree was fully and clearly displayed in the lens.

Then he stood there motionless.

If anyone else is around, they will think that he is waiting for the perfect moment to press the shutter. But in reality, he was given something and couldn't move.

Suddenly, the bronze divine tree flashed brightly, and a beam of light sank into the man's right eye along the camera lens, and a wisp of divine consciousness overflowed from the man's head and headed straight for the sacred tree.

The man fell to the ground with a thud, and before he was out of breath, two syllables came out of his mouth clearly, "Wow"!

In English, it's "WOW" again!
