The Science Fiction World of Xueba

In the following time, the coalition government began to mobilize in all directions and officially started the construction of the "Snow Project".

As an advocate of the "Snow Project", Pang Xuelin was also appointed by the coalition government as the chief scientist of the project and participated in the construction of the "Snow Project".

To Pang Xuelin's surprise, two days later, he met Yao Bingxia, Du Jiaxiang and others who escorted the first batch of metal-based graphene composite materials to Hope City.

The earth crosses the asteroid belt, and various accidents are inevitable. Hope City, where the coalition government is located, is one of the safest areas on the entire earth. The arrival of Yao Bingxia made Pang Xuelin feel at ease a lot.

With the official launch of the snow project, Pang Xuelin has truly seen the level of aerospace technology in this world.

According to the preliminary plan of the snow project, humans will launch 2,000 nuclear bombs equipped with metal-based graphene composite materials, and make them park in the designated positions calculated by engineers.

All 2,000 nuclear bombs were launched from the earth, and the vehicles carrying these nuclear bombs were actually fusion-powered aerospace planes.

Compared with the three-body world and the Martian world that Pang Xuelin experienced before, the aerospace engineering level of the wandering earth is obviously higher than that.

These aerospace planes have a self-weight of more than 500 tons, and a take-off weight of more than 1,500 tons. They can carry nearly 1,000 tons of fuel and cargo, travel freely to and from geosynchronous orbit, and have a self-sustaining force of several tens of thousands in space. moon.

Compared with the combined power space shuttle used in the Martian world, this aerospace aircraft is not a product of an era at all.

Pang Xuelin also looked for the technical materials of these fusion-powered aerospace planes and space warships.

He discovered that the fusion reactor used by the aerospace plane is a miniaturized product of deuterium-tritium nuclear fusion, and its maximum power can reach the level of one million kilowatts, which can almost meet the power consumption of a small and medium-sized city in the real world.

With such a huge energy output, it is no wonder that dozens of modified flints can be loaded into the air at one time.

If it weren't for the volume of Flint, its loading capacity could be even greater.

As for those space battleships, it is even more exaggerated. The total mass of any one of them exceeds 100,000 tons, which is several times larger than the International Space Station in the world of The Martian.

It is said that these space warships can accelerate to a maximum speed of 2,000 kilometers per second (in principle, if a warship has enough fuel in space, it can accelerate infinitely until the relativistic effect occurs, but in general, after the warship accelerates, it needs enough The fuel guarantees deceleration, and the basic operation of the battleship must be maintained, so the maximum speed will be calculated according to the maximum speed that can be achieved by consuming one-third of the fuel acceleration), and can persist in space for two to three years under the condition of lack of supplies .

Of course, what shocked Pang Xuelin the most was the Navigator International Space Station. It was said to be a space station, but in fact it was also a super warship.

Its total tonnage exceeds one million tons, almost equivalent to a space city, and can accommodate more than 100,000 astronauts at most.

It is said that there are three nuclear fusion reactors inside the space station alone, which are mutually redundant, which can ensure that even if two fusion reactors are damaged, the remaining one can still maintain the normal operation of the space station.

Pang Xuelin has never seen the real body of the Navigator space station, but it can be seen from the pictures that the Navigator space station is many times larger than the space station shown in the movie.

Therefore, for humans, it is not a problem at all to deploy hydrogen bombs at fixed points in the asteroid belt.

The space plane carries the Flint and docks with the space warships parked above the geosynchronous orbit, and then these space warships transport the Flint and drop it to the corresponding position near the Earth's waterway in the asteroid belt.

Time passed day by day, and the progress of the snow project was orderly. Before the earth officially entered the asteroid belt,

The snow project finally completed the deployment of all hydrogen bombs.

Subsequently, these hydrogen bombs were detonated one by one, forming giant dust clouds 10 million kilometers west of the earth's waterway.

After another week of testing, it was soon discovered that the tracking effect of these dust clouds on asteroids was even better than Pang Xuelin's prediction.

Any asteroid with a diameter of more than ten meters can show a clear trajectory on the radar screen 10 million kilometers away after passing through these dust clouds.

The snow project was a huge success.

The only regret is that due to the limited production of metal-based graphene materials, these dust clouds cannot cover all waterways, and can only monitor key waterways.

But even so, the existence of these dust clouds has greatly reduced the workload of the space fleet, which has expanded the space fleet's alert range to the Earth's waterway to 2 million kilometers, greatly increasing the Earth's response time.

...

Half a month later, the earth officially began its journey through the asteroid belt.

Except for a very small number of staff who must be on duty on the ground, most people on the ground have withdrawn into the dungeon.

The space fleet also began to get busy. In the earth cab, Pang Xuelin was in the planetary engine control center and saw the scene of antimatter bombs destroying asteroids for the first time.

Through the pictures captured by the external camera of the space battleship, Pang Xuelin saw that an asteroid with a diameter of 200 meters appeared in the warning range of the space fleet.

Subsequently, the space fleet launched an interstellar missile equipped with an antimatter bomb warhead. The missile traveled tens of thousands of kilometers and accurately hit the asteroid.

At the moment when the antimatter bomb exploded, even tens of thousands of kilometers away, the lens of the camera was completely covered by a white light. After more than ten seconds, the white light gradually disappeared. At the position where the asteroid was before, the asteroid with a diameter of nearly The two hundred meter asteroid has completely disappeared.

It is said that on the ground, the flash produced by the antimatter bomb instantly illuminated the entire eastern hemisphere in the dark night, as if a super sun suddenly appeared in the sky.

Such bright light, if viewed directly with the naked eye on the ground, may directly cause blindness.

And this is just the burst of energy after one hundred grams of antimatter is neutralized with positive matter (the energy produced by one gram of antimatter is equivalent to a 40 million-ton equivalent thermonuclear bomb), but it is enough to smash this asteroid into Thousands of pieces.

Due to the gravitational effect of the earth, these asteroid fragments descend on the earth after a day or two.

Countless spectacular fireballs began to appear in the sky.

Of these bolides, only some burn up in the atmosphere, and most of the rest fall in the southern hemisphere.

From the pictures captured by drones and ground surveillance cameras, it can be seen that a bolide, like a punishment from heaven, turned into a gorgeous fireball under the friction of the atmosphere, and instantly hit the frozen ocean.

A white mushroom cloud formed by water vapor soared into the sky, and the thick layer of ice shattered rumblingly. The plane within a few kilometers was completely shattered. ocean decay.

Finally, in the footage from the drone, the ice sheet within a few hundred meters of the impact point has remelted into seawater.

And this is just the damage caused by a bolide with a diameter of less than one meter.

What is even more frightening is the scene when a bolide with a diameter of tens of meters or hundreds of meters hits the ground.

In the early twentieth century, an asteroid with a diameter of 20 to 30 meters fell near the Shiquan Tunguska River in the Krasnoyarsk Territory of Russia and caused a big explosion. This explosion will cover an area of ​​about 500,000 acres (2,000 square meters) km) of the Siberian forest was flattened and an impact crater with a diameter of 100 meters was formed on the ground.

Scientists later believed that the power of the Tunguska explosion was approximately equivalent to 10 to 20 megatons of TNT, which was 1,000 times more powerful than the atomic bomb dropped on Hiroshima.

Impact scenarios like the Tunguska explosion happen every day.

And sacrifices followed.

On the second day after the earth entered the asteroid belt, a space fighter jet cleaning up the asteroid was hit by asteroid debris, causing the pilot to die.

Even a week later, a space warship was hit by a high-speed asteroid fragment and the fusion reactor, and more than 10,000 people in the warship died instantly.

The biggest tragedy occurred when the earth entered the asteroid belt for a month, and an asteroid nearly 100 meters high entered the atmosphere. In the atmosphere, the asteroid broke into three pieces by friction with the atmosphere. One of them changed its orbit. It hit the New Delhi No. 2 engine, which directly caused the fusion core module of the New Delhi No. 2 engine to melt.

The core cabin burned down the emergency exit connected to the underground city, coupled with the lack of sufficient electricity, the underground city was unable to stop the magma invasion. In the end, the 400,000 people in the New Delhi underground city were finally buried alive by hot magma.
