"But ......," Hai Ge still didn't quite believe, "if the Earth-Moon Tai route is connected by three fixed space stations from the U star, why haven't the space scientists on Earth discovered their existence until now?" ”

Success sighed and replied, "You must know that Wedel-U was not destroyed yesterday. Billions of years later, space stations built by ultra-ancient extraterrestrial civilizations have long since lost their original appearance and become as inconspicuous as floating meteorites. The three routes were also covered in interstellar dust, and the earthlings would not have been able to spot them anyway if no one had clearly marked them. ”

Haige has seen humans launch spaceships into space on launch vehicles on live television. The spacecraft of the earthlings will set a target before setting sail, and the route is definite but not fixed, and if it wants to move forward along a fixed trajectory, I am afraid that the earth's space technology will not reach such a high level in a few hundred years.

As early as billions of years ago, U stars have laid interstellar rails in the universe like laying train tracks, and this level of advancement is really beyond the reach of earthlings!

Presumably, before the establishment of the solar system, the interstellar traffic in this cosmic space was very busy, right? Every day, a variety of strange-looking space vehicles shuttle through different routes.

Haige imagines what a magnificent world it used to be for the U-Stars to come and go through the air communication stations located at different Lagrange points, and even to trade in space!

But a large-scale space transportation network must comply with space traffic regulations, right? This is just as the various modes of transportation used by humans on Earth will be managed by managers, and space navigation should also have strict traffic regulations and enforcement personnel. What do those law enforcers look like?

Hai Ge thought about it for a while, realized that it was too far off topic, and quickly retracted his thoughts, but after thinking about it carefully, he felt that it was wrong, the space transportation network of the U star had long since ceased to exist, and why didn't the Blue Whale 700 fly directly from the earth to the sun?

So he complained and asked Success: "When has this been, and is it still guilty of paying attention to those red tapes?" Wouldn't it be faster for us to save some trouble and fly directly from the earth to the sun in a straight line? ”

After successfully seeing Haige's stubbornness, he had to patiently explain the reason: "Don't forget, our trip in the shadow is not just to say goodbye to the sun. This will involve the future plan to save the earth, and one of the most important projects in the rescue plan is the construction of interstellar orbit. Even if Mr. Wedell had found a Lagrangian point that could have been artificially established through complex measurements, the pilotage equipment for the triangular space orbit would need to be supported by ultra-high-power energy, which would simply not be met by the Earth's current comprehensive power supply capacity. ”

"In other words, if there is no energy supply, the stationary space station will not work, right?"

"Exactly. Taking this Earth-Moon Pacific route as an analogy, the amount of electricity required to ensure its normal operation of the earth time for one month can supply the entire earth for ten years. Therefore, the power generation equipment of the space station must be countless times more powerful than that of the earth, otherwise the orbit will be like a virtual one, unable to attract spacecraft to sail along the established route. ”

"And how advanced can your generators be? Is it more powerful than solar energy? Haige thinks that success is boasting, and is a little unconvinced.

Chenggong smiled and said, "In a universe with darkness as the background, it is not easy to collect solar energy on such a large scale, sir, you are really joking. ”

Hai Ge knew that he had said something ignorant again, and his face turned red and he stopped making a sound.

Success continued: "To solve this dilemma, Mr. Weedel decided to use the hydrogen pump magnetic generator that the U-stars used in the past. This type of generator generates electricity by using isotopes of hydrogen and helium as nuclear fuel, mimicking the process of fusion in the sun's core. The advantage of the hydrogen pump is that it can not only ensure that the rail is not interrupted, but also can operate on its own without AI operation, and continue to generate electricity for tens of thousands of years. ”

"Well, in this way, hydrogen pumps are a good thing, but why don't earthlings use them?"

The successful answer was simple: "The Earth is a water planet, and it does not have the heat of the Wedel-U star that exceeds the sun's rays several times, so it cannot use hydrogen pumps to generate electricity, otherwise if the equipment fails, the entire planet can be blown into dust in one second." ”

"Mom~ I see!" Hai Ge was scared into a sweat, and the heaviness hit his brain again. But his mind was still spinning fast, and in a blink of an eye, he thought that if the train derailed, it would cause a major railway accident, so he couldn't help but ask: "If the spacecraft deviates from the intended trajectory, how serious will it be?" ”

Chenggong replied: "Sir doesn't know, the function of the Lagrange point is to find the most stable flight path in space, to ensure that the spacecraft can always travel on a fixed trajectory, so as not to cause space traffic accidents." Space may seem calm, but there are countless potential threats in the darkness. They are untold black holes and unnamed dark matter, like reefs hidden behind the waves in the ocean, ready to sink a giant ship in motion. The route of the fixed orbit has been precisely surveyed to ensure that the aircraft travels according to the safe route. ”

"I'm not afraid of 10,000, I'm afraid of what if, are you really so confident?" Haige pursued this issue relentlessly.

After a pause, Success replied, "If the ship deviates from orbit, the problem is not only a potential threat, but also the disintegration of the hull under the sudden change in air pressure. The only thing the passengers could do was to flee to the nearest space docking station in their space survival suits and wait for the rescue spacecraft to arrive, provided they could make it to the docking station alive. ”

"It seems that if you don't follow the track, the consequences are not ordinarily serious!" Hai Ge wiped his forehead, and finally stopped asking.

At the end of the 22nd century, the aerospace level of mankind has reached the point where it can use manned spacecraft to take ordinary people to space for a circle, so Xijin City, as a global metropolis, has indeed erected a space tower that runs straight into the sky and is used exclusively for interstellar civil aviation far away from the city center, and is named Xijin Interstellar Spaceport. The successful take-off location was in that space tower, and the name of the place made Hai Ge sound more intimate, but also inevitably sad.

The Blue Whale 700 civilian spacecraft began to glide and soon to enter the alien-built orbit with the help of a rocket. Haige's eyes widened, curiously waiting to see how the scenery outside the porthole would change.

According to Chenggong, the Earth-Moon Tai route had another name in the heyday of the U star, but after the destruction of the U star, this was the first time he restarted the route, and since one of the fulcrums of the triangular orbit was located on the earth, it was renamed the Earth-Moon Tai. There are a total of five pilot feeder stations on this route, and the operation of the feeder stations has long ceased to operate after the power consumption in the feeder stations has been exhausted. Successfully started the hydrogen pump magnetic generator, but there was no intention of reactivating the connection station.

After taxiing for some distance, the Blue Whale 700 spacecraft suddenly exploded with great force and rose from the ground, rushing towards the vast mist in the rising white mushroom cloud. Hai Ge longed to enjoy the vast starry sky, but when he left the earth, all he saw was a white light flying past his ears.
