Earth Era

Four thrusters were thrown out from the Xinghai spacecraft, and then began to roll continuously in space. ↑, but they only tumbled for a moment, and a pale blue flame shot out from their tails. Under the impetus of these fireworks, their motion status quickly stabilized, and then they began to fly toward the distant cosmic deep space.

All operations of this sailing to the signal source are automated and do not require Wei Feng to intervene. After the four thrusters were launched, Wei Feng entered the idle state again.

The so-called idle state does not mean that there is nothing to do all day, but that you need to do some boring and boring recovery training. Everyday life is step by step, exercise, then rest, and so on.

During the previous six years of sleep, there were also some notifications sent to Weifeng from the earth side. Wei Feng flipped through it and found that most of those things were edited and sent to him by the Time Traveler team, and most of the things described in it were some subtle changes in human civilization. Although these things have no exact value, they clearly describe the development trend of events. This made Wei Feng feel heavy again.

The longer it goes, the worse it gets. What happens when you wait until things get to a certain extreme?

"I hope all the things I think are just unfounded worries." Wei Feng comforted himself, "There are so many wise men in human civilization, how can they not think of what I can think of? They must already have it. There is a way to deal with it, or, my idea is simply wrong. I should do my thing first, an alien civilization probe, presumably the government will be interested in this thing. "

Time spent two months in this boring wait. At this moment, there is a distance of 15 billion kilometers between the Xinghai spacecraft and the four probes, and. This distance is still increasing rapidly with the passage of time. Every second that elapses means that the distance between the two increases by 3,000 kilometers.

The distance of 15 billion kilometers means that the one-way communication delay between the two parties has been as high as about fourteen hours. Each command is sent from the Xinghai spacecraft to the signal source and received by the thruster. Then the thruster will return the command result to the Xinghai spacecraft, which will take a total of twenty-eight hours. In other words, Wei Feng issued an order. It takes twenty-eight hours to get the execution result of the instruction.

However, artificial intelligence programs are incapable of performing such tasks. At the same time, different instructions cannot be performed at the same time, and they are causally related. That is to say, Weifeng needs the feedback result of the previous instruction as a basis to decide the next one. command, which means that Wei Feng cannot send all the commands in one go and hand them over to the thruster for execution, but must wait patiently. Do this task slowly at a rate of one more instruction a day.

And every day that passes, the two-way communication delay between the two parties increases by about an hour.

This is a job that is a great test of patience. Because there is no standard execution process for this task, Wei Feng must continue to explore and rely on his own experience to judge the correct task execution steps. If one step is executed incorrectly, it may mean that all the task steps performed in the previous ten days are wasted. Sometimes when receiving wrong feedback data, Wei Feng is so mad that he can't wait to rush out and do it himself.

A lot of time is wasted in this situation. The end result is that it took Weifeng more than a month to fix the four thrusters on the signal source, and set the propulsion and orbit parameter data for them.

But this time has greatly exceeded Wei Feng's expectations. In Ye Luo's calculations, even if everything goes well, the signal source must be pushed to a distance of 100 kilometers from the Xinghai spacecraft. The originally calculated thirteen years was far from enough. The latest calculations show that it will take forty-seven years.

Forty-seven years is equivalent to a quarter of a person's life cycle even for the average human lifespan today. For such a long time, all Wei Feng could do was to bring an insignificant little guy from deep space to his side.

The price is huge though. But Wei Feng had to do it. Because this is Wei Feng's only option.

"The ignition push command has been sent." Ye Luo still maintained a calm tone, "We will receive feedback on the execution of the command in about twenty-six days."

"Huh" Wei Feng let out a long breath. If you add the twenty-six days to the twenty-six days, Wei Feng has been awake for nearly five months this time. Compared to the previous two months of waking up every time, this time has exceeded too much.

In these five months, less than one day was actually used for work, and the rest of the time was wasted on the increasingly serious communication delay. Now, the delay time of two-way communication has risen to a terrifying twenty-six days.

Weifeng has never been so eager to have ultra-distance communication technology as it is now. If there was an ultra-distance communication technology, Wei Feng would have finished this matter long ago.

But at the same time, Wei Feng knew that the problem of communication delay was not only bothering him. It also plagues all human beings in the solar system. Although the footsteps of human civilization have stepped on the icy land of Pluto, the shortest two-way communication delay between Earth and Pluto is ten and a half hours. This has seriously hindered the communication between people.

Scientists have carried out a lot of research on the technology of ultra-distance communication, and many scientists have devoted their whole lives to this problem. But unfortunately, until Wei Feng set off, human civilization still did not see the dawn of mastering ultra-distance communication technology.

Difficulty in communication of information will inevitably lead to mutual isolation both psychologically and physically. The report sent by the time traveler team to Wei Feng clearly described this problem: "We found that people born in four larger human settlements, the Earth, the Mars base, the Jupiter base, and the Saturn base. People already have a deep psychological estrangement for the rest of the world. People tend to have a deep sense of identity with their birthplace, but they only have a broad concept of the entire human civilization and do not have much identity. Similarly, in the political arena, In China, people born in different places will naturally form their own small circles, and different small circles will often break out fierce conflicts in terms of the overall resource allocation and policy inclination of human civilization, etc. They look like countries The leaders of different countries of the era are generally not regional leaders of a unified human government."

This is due to the inconvenience of traffic and the consequences of communication delays. If either of the two can be resolved, it would be absolutely impossible for human civilization to form such a situation.

The existence of communication delay has not caused serious consequences in human civilization, but for Wei Feng, the consequences of communication delay have made Wei Feng unbearable.

Because of the existence of communication delay, Wei Feng must stay awake for a long time to maintain the continuity of task execution. If it is kept awake for a long time, the life support equipment of the spacecraft must also be turned on at the same time to ensure the survival of Weifeng, and the food will be continuously consumed, which will cause a great deal of material and energy reserves in the Xinghai spacecraft. challenge.

Wei Feng originally planned to wake up for two months each time and hibernate for ten years each time, but now Wei Feng has been awake for five consecutive months, which means that Wei Feng’s awakening this time has consumed a portion of his budget. Twenty-five years of material reserves.

This is the vast space, where Wei Feng can't get any resources to replenish. Therefore, every point of resource reserve Wei Feng in the spacecraft must be carefully calculated.

"I can't wait any longer." Wei Feng said, "Waiting for 26 days while waiting is a huge waste of resources, and our material reserves can't support it. I'll go for a short hibernation. Well, if there is an error in the execution of the task after twenty-six days, then wake me up, if the task is carried out smoothly, then replace the short-term hibernation with the long-term hibernation, and wake me up after ten years."

"Good captain." Ye Luo said, "You are very wise to do this."

Wei Feng went into hibernation again, and the Xinghai spacecraft entered an icy state again. But this icy state didn't last long. Even Wei Feng, who had woken up, felt this. Therefore, the first question Wei Feng asked after waking up was: "How long have I hibernated? I feel like I only slept for a while~www.readwn.com~ Yes, you have only hibernated for 20 years. Six days. The reason why I woke you up was because of an error in the execution of the mission." Ye Luo said calmly, "Our mass budget for that alien device is fifty tons. In order to prevent accidents, our actual operation is The fuel for the thrusters is based on a mass of 100 tons. However, the four thrusters were fully activated, and the alien device did not move at all. This means that its mass has far exceeded our expectations.”

"How could this be?" Wei Feng frowned deeply, "Then what's the mass you calculated?"

"I can't give you precise data, but I can give you the lower limit of the mass of this device. According to my observation accuracy and the thrust of the thrusters, the lower limit of the mass of this alien device is five million tons." To be continued
