Earth Era

Five hours have passed. It was almost six o'clock in the afternoon, but the direction of the sun was always quiet. Neither satellites, observatories nor radio telescopes have received any signals with logical characteristics from the direction of the sun.

Perhaps, as the person in charge of the observatory said, "either that K2 civilization does not exist, or they ignore us." And now five hours later, because of the angle difference caused by the earth's rotation, even if The direction of the sun really sent a signal, and the Galaxy radio telescope could not receive it.

Obviously, because it is built in a valley, the Galaxy Radio Telescope cannot rotate freely to aim at different directions. It can only follow the earth and scan a certain range of the celestial sphere along a fixed orbit.

However, it does not matter if the Galaxy radio telescope cannot monitor the sun. At this moment, the freely rotating radio telescopes built in other parts of the earth are still chasing the sun's shadow until the sun sets.

The highest intensity monitoring operation will last for three days. If no information is returned after three days, the monitoring of the direction of the sun will not stop. There will still be at least two large radio telescopes for this task.

"Then wait three days." Zhao Huasheng said: "Maybe some people think that it is easier to communicate with extraterrestrial civilizations to change the current predicament than to rely on our own strength to change the sun, but I don't think so. I think if the sun is because of If our own physical mechanism changes, we still have some chances. If there really exists a K2-class civilization, we don't have any chance. So... I hope there will never be a reply from the direction of the sun."

"Anyway, wait for these three days." said the person in charge of the observatory.

Zhao Huasheng, Li Wei, Meng Zhuo and others stayed in the Galaxy Observatory. After the Galaxy radio telescope was pointed in other directions and could no longer observe the sun due to the rotation of the earth, the Galaxy Observatory re-entered its daily work rhythm.

This is the most sensitive ear built by human civilization. It can even pick up radiation emitted by distant river systems seven billion light-years away. Since the Galactic Radio Telescope was built, it has discovered at least 500 neutron stars and white dwarfs, and through gamma-ray monitoring, it has identified at least 300 new suspected black holes. There are many extremely important discoveries in the close binary star, Cepheid variable star, supernova explosion, double neutron star or white dwarf star system, and the compact star-main sequence star model.

There are huge amounts of radiation and signals in the universe all the time. The role of the Galaxy Radio Telescope is to monitor these signals, eliminate useless interference, and screen out signals that are valuable for astronomical research.

Zhao Huasheng is also an astronomer. Although the research direction is different from those of the Galaxy Observatory, this does not prevent Zhao Huasheng from participating. Zhao Huasheng stayed at the Galaxy Observatory for three days, until noon on the third day.

Seventy-two hours have passed, and the direction of the sun is still silent, still silent. Not a single receiver in the world has picked up even a suspected signal.

At this time, Zhao Huasheng received a notice from Wang Tang: "With the consent of the head of state, we have decided to restart the solar exploration program. There will be at least 30 probes and a manned spacecraft to leave the earth for the sun."

"Very good." Zhao Huasheng said, "When will it be launched?"

"Tomorrow the astronauts will set off from the earth."

"Okay, I'll go see them off too."

"Welcome." Wang Tang said.

When the communication was cut off, Zhao Huasheng said to Meng Zhuo: "There is still a period of time before the rocket launch. Let's go to the Vulcan solar telescope to take a look. Maybe we can find some clues left by Director Li Qi there."

"Okay." Mengzhuo agreed. After an hour of preparation, five helicopters took Zhao Huasheng and his party out of the Xinghe Observatory and started to set off for the Vulcan solar telescope.

The Vulcan Solar Telescope is an optical telescope, so it must be built in a place with clean air to reduce the influence of the atmosphere on light. Only in this way can the observation accuracy be improved. In fact, the construction site of the Vulcan telescope is a mountain range, which is more than 5,000 meters above sea level, and is dry all year round with little rainfall.

Located at low latitudes here, although the solar radiation has dropped a lot, the temperature of the plains here remains above zero. But it was different on the mountain. At an altitude of more than 5,000 meters, the temperature has dropped to about minus 30 degrees. In such severe cold, Zhao Huasheng's helicopter came to the open space in front of the Vulcan telescope.

The person in charge of the Vulcan telescope base received Zhao Huasheng and his party. After bringing Zhao Huasheng to the base from the cold and freezing outside, he left alone, and another person came to accompany Zhao Huasheng and others. This is a lanky middle-aged man with glasses and a pen in his jacket pocket. He looks like an intellectual of the last century.

"Yes, our telescope is indeed built by Director Li Qi." The middle-aged man said, "After the unfortunate death of Director Li Qi, at least seven people from the scientific research department have come here to check, all of them I haven't found anything of value. Why, are you also from the scientific research department? Come here to investigate what Director Li Qi has?"

Zhao Huasheng nodded, "Yes, we hope to find some clues left by Director Li Qi here."

"No, not at all." The middle-aged man shook his head with regret, "Director Li Qi also has the authority to use this telescope, but after the telescope is completed and put into use, in addition to receiving the observation data here , he never paid attention to this place again. How could there be anything left of Director Li Qi here?"

Zhao Huasheng asked: "Director Li Qi also has the authority to operate this telescope? So is it possible that this happens, that is, Li Qi directly operates the telescope with his own authority to conduct some observations without going through you? "

"Theoretically, this possibility exists." The thin middle-aged man said, "But the first seven investigators from the scientific research department have already investigated this matter, and they don't seem to have found anything."

"Yes, the staff of the scientific research department have investigated this matter." Meng Zhuo said, "the investigators did not find any traces left by Li Qi. There are two possibilities for this situation, one, Li Qi really did not do anything, and two, Li Qi did the operation, but he removed these traces perfectly. We don't know what kind of possibility it is. Because this information has no value, I didn't report it to you. "

"Well." Zhao Huasheng nodded, thought for a while, then turned to Li Wei and asked, "Since it is an optical telescope, did the people from your Institute of Optics participate in the construction of this telescope?"

"Participated." Li Wei said, "The investigators also investigated the construction drawings and technical parameters of the telescope, and found nothing strange."

"So..." Zhao Huasheng pondered again, and said to the thin middle-aged man, "Can we go and take a look at this telescope?"

"Of course." The middle-aged man said, "We can go there by car."

The group took a car to the huge factory where the telescope was located.

Optical telescopes are different from radio telescopes. It is not a pot-like surface, but a lens barrel structure in the traditional sense, but the volume is much larger. When it is to be used, the baffle above the factory building is removed, allowing light from a distance to enter its mirrored surface.

Although it has the same mirror structure, it is different from other telescopes. Because other telescopes are mainly used to observe extremely distant celestial bodies, and it is to observe the sun. The sun was too big and too close, and if left untreated, the sunlight gathered by the condenser would be enough to melt the steel. Therefore, there are several filter plates on the outside of the telescope, and the staff in the base can easily adjust the light intensity entering the telescope depending on the observation needs.

There are many workers busy here~www.NovelMTL.com~ On the huge screen in the factory, Zhao Huasheng also saw the real-time image of the sun. It was a fiery big fireball with a dark red color, and even after a very large amount of extinction, it still looked full of shocking power.

Because of the outbreak of the solar crisis, the number of observation tasks of this telescope has suddenly increased a lot, and even the staff here are three or four times more than before.

Zhao Huasheng didn't say a word, but just wandered around the busy researchers, looking at the layout here, looking at the data that was sent back, and occasionally looking at the huge telescope mirror.

After a while, Zhao Huasheng asked thoughtfully, "How much resolution can this telescope achieve for solar rays?"

"Resolution accuracy? What do you mean?" The thin middle-aged man asked with some doubts.

"Light intensity. For example," Zhao Huasheng said, "if its accuracy is adjusted to the highest, is it possible for it to find a specific area of ​​the sun - this area may be very small, let's say ten square kilometers, it Can you find the change in light intensity in these ten square kilometers?"

"Of course it can be found," said the thin middle-aged man. "This telescope is very powerful. It is one of the most advanced ground telescopes that we humans have built."

"What kind of precision can be achieved? Can a luminosity change of one in a million be detected?" Zhao Huasheng asked immediately.
