Wallfacer: I suggest that humans be bad

Chapter 75 Forced Landing Comet Movement
In the modern age where material life is extremely rich, everyone has their own pursuits.

Many people are addicted to the virtual world, because in the virtual world, things that are difficult or even impossible to do in reality can be easily done: war, magic, battleships, different worlds...

But there are also people who love the most authentic game—reality.

For example, extreme athletes who enjoy pushing the limits.

They said: Challenge the limit in the game, what kind of limit is it.

With the improvement of physical fitness and the changes in the physiological structure of new humans, the conventional extreme sports on the blue star can no longer meet their needs for pleasure, and they set their sights on the vast universe.

Downhill, surfing, tornado gliding... For new humans, the dangers of these extreme sports on the ground are not worth mentioning compared with the dangers of extreme sports in the universe.

Conquering and overcoming this danger has become the source of happiness for some people, and fighting against the sky is a great joy.

Among them, one of the more popular extreme sports in the universe is a life-threatening sport called forced landing on a comet.

The so-called forced landing on a comet refers to the artificially piloted spacecraft starting from the comet's tail and landing on the comet's nucleus.

A comet consists of two parts, a head and a tail.

The comet head includes the coma and the comet nucleus. The comet nucleus is the core of the comet. It is generally composed of stones, iron, dust, ammonia, methane, ice and other substances. Its diameter is very small, and the diameter is several kilometers to more than ten kilometers. , the smallest is only a few hundred meters.

The comet tail begins to appear when the comet is only [-] million kilometers away from the sun, and gradually changes from small to large, from short to long.

The comet tail is composed of carbon dioxide, hydrogen, dust, etc., and its longest length exceeds [-] million kilometers. To land on the comet nucleus from the comet tail, the speed of the spacecraft needs to exceed the speed of the comet, the resistance of the dust needs to be overcome, and the influence of the complex environment needs to be corrected at all times.

Accidentally, the ship crashed and the death rate was extremely high.

Extreme athletes usually spend several years building a small nuclear-powered spacecraft by hand, usually weighing about [-] tons.

Through the credits issued every month, they order various materials and instruments, rent the top industrial equipment, and build their own cars bit by bit.

Each of these people is the top elite of human civilization, because there are not many doctorates, and the credits issued every month are not enough to buy nuclear fusion fuel.

Time goes back to 202 in the Era of Crisis, the year before the Trisolarans surrendered, the explorer and field survivalist Reynolds set off from Jupiter to challenge.

Renault lived alone in an abandoned city for three full years, and finally returned to the settlement of human civilization with a hand-built helicopter. He is one of the top survival masters.

The comet he wants to challenge is named Temple Tuttle, with a nucleus nearly 2000 meters in diameter and a tail tens of millions of kilometers in diameter.

The period around the sun is about 33 years. When it is closest to the sun, it is only one astronomical unit, which is about the same distance from the blue star to the sun. The Leonid meteor shower is caused by it.

According to the black box found, Reynolds was driving the spacecraft, galloping in the tail of the comet at a speed far exceeding that of the comet, ignoring the gas and dust, but the spacecraft had problems when it landed.

The specific reason is unclear. Experts speculate that there should be a problem with a certain sensor, which caused Renault to fail to make a correct judgment in time, resulting in the ship crashing and death without a whole body.

This is normal. It's no wonder that something as precise as a spaceship operates in such a complicated environment as a comet's tail.

In this way, there is another pile of scrap iron on the comet. There are a lot of superconducting materials and scarce nuclear fuel in the scrap iron.

The protection measures for nuclear fuel are always very strict, and the container that houses it cannot be damaged by a mere stall, fall or collision.

The nuclear fuel contained in these containers is reserved for the return voyage.

In the solar system, there are about hundreds of millions to billions of short-period comets. The return period around the sun is within 200 years, and most of them are within ten years. The diameter of the comet nucleus is between several hundred meters and several kilometers.

On the eve of the doomsday battle, hundreds of people go to challenge the forced landing on the comet every year, and it is unknown how many of them are left behind.

After the doomsday battle, human civilization no longer has enough resources to support individual super extreme sports. The cosmic extreme sports that have been glorious for half a century have declined in an instant and cannot be recovered in a short period of time.

There is no man's land around the comet.

……

In Crisis Era 209, the proposal to carry out dirty bomb bombing on extraterrestrial planets was passed. Anyway, after the nuclear weapons industry is completed, it will operate almost fully automatically. It will be enough for everyone to work hard for 3 or 4 years.

However, the proposal to push comets to hit planets and stars was not passed, with only about 50.00% approval rate, because building a large number of comet engines requires the industrial strength of the heyday of mankind, which is not realistic at all, and will threaten the survival and development of individual civilizations .

For this result, the leftists are very pleased.

The industry for making nuclear bombs couldn't be placed on Blue Star, so it moved to Jupiter's asteroid belt.

Since it is going to be bombed, it must be thoroughly bombed. The star-level nuclear bomb is buried deep in the ground, and a large number of dirty bombs are detonated on the ground. They vowed to leave a mess for the Trisolarans.

Everyone is doing this seriously, no matter whether they know about the Snow Mark Project and?The true strategic purpose of the plan.

The Trisolarans don't care, as long as they can't blow up the sun, their attention is all on the Starfleet at the moment.

Digging a well requires industry and personnel, so after the recovery of the nuclear fuel extraction industry and the civilian spacecraft repair industry, the coalition government began to emigrate.

Immigration is dangerous, and it's all voluntary, but there are still many people who are willing to go: Come on, blowing stars is so cool.

It was also in this year that Ding Yi returned to the moon and started the lunar particle collision experiment that he had been thinking about.

Human beings have successfully unfolded protons in low dimensions, and in two dimensions, but just unfolding is useless. Humans do not have the ability to raise protons to high dimensions, nor do they have enough time to etch circuits.

At the same time, the curvature engine research and development project was launched, and it was built on the moon at the request of Sophon, because the water droplets are located between the earth and the moon, and human laboratories can be destroyed immediately if there is a problem.

After Venus completed the emigration, everyone tried to repair the relatively intact dock and build new warships. As soon as they made a move, the water droplets flew to Blue Star slowly, without telling the coalition government why.

The coalition government was taken aback, and immediately understood that someone had violated the ban, and quickly notified the off-terrestrial base to stop illegal activities. Later, they severely punished a group of people. If there were no casualties, they were only imprisoned for life.

After this trial, the left-behind faction determined that the sophons in the solar system have probably been nailed to water, gold, earth, moon, fire, wood, and Neptune, exactly seven. Even if there are one or two free sophons, they probably won't Wandering around the solar system.

……

In August 210, the Era of Crisis, the navigator formation, the Natural Selection, everyone woke up from hibernation.

At this moment, the three warships have finished decelerating, and they will search for the tombstone 8 nearby to take away the civilization inheritance on it.

Radar quickly spotted the craft.

Sending a radio, Tombstone's brain didn't reply.

Zhang Beihai put on his spacesuit and asked worriedly, "Dongfang, that unmanned ship has been in operation for more than half a century. Has its computer been damaged? I remember you said that the lifespan of an electronic chip is only 20 years."

All warships use electronic computers, and photonic computers will be affected by sophons on the optical path, which is not safe.

Dongfang shook his head and said, "I don't know, but the database should be fine. The way it records data is very primitive. In short, it is to engrave words on stones. From the perspective of database design standards, information retention is very important. Hundreds of millions of years will not be a problem."

Dozens of people took small aircraft and approached the ancient battleship that was significantly smaller than the star-class battleship.

The hull of Tombstone is full of pits and pits, and there are traces of rust and micrometeorite impact everywhere. It does not have laser weapons to clear obstacles.

After searching around, they didn't find the door, so the group stopped on the deck and carefully cut the armor of the battleship with the laser weapon that came with the aircraft.

After working for half an hour, everyone entered the inside of the tombstone. It was extremely dark inside and there was no power supply.

Zhang Beihai called up the design drawing of the tombstone, compared the signs, and confirmed the location, "We are now in the aisle between the industrial area and the material storage area. Under our feet is the nuclear fusion reactor."

"Through the industrial area, it is the database."

Someone held up the lamp and looked at it for a while, then pulled out a metal tank from the wall, observed for a while and said: "There is also liquid helium three, it seems that there is a problem with the intelligent central control."

"Restart the reactor?"

Dongfang shook his head: "For safety's sake, don't activate it. If it blows up, we will all die."
