Simulating the impact of an asteroid hitting the Earth on every part of the globe, and the interaction between the impacts, is a very complex matter. Once simulated, the computing power required is unimaginable to ordinary people.

But now, according to Lu Ming's requirements, such simulations need to be carried out more than 20 million times. Even with the supercomputing power of the Minor Planet Warning Center, it will take two full days to complete.

During these two days, all scientific research tasks will be suspended. Fortunately, it did not interfere with the daily observation work of the early warning center.

Because if it's just an observation, you don't need to use supercomputing.

In the face of Lu Ming's request, the supervisor surnamed Wang agreed with a serious expression and immediately started the operation.

He translated Lu Ming's requirements into a meticulous computer language, and then input them into the simulation program. On the visualization screen, Lu Ming saw the detailed process of the first simulation.

Of course, for supercomputing, this first simulation only took a few milliseconds. In order to make the simulation results more intuitive for the operator, it will take up to half an hour to present them on the screen.

As a result, Lu Ming saw a huge asteroid, with a relatively inclined orbit, rushing towards the earth's Pacific Ocean.

The asteroid is more than 20 kilometers high at its longest point, and its width and thickness are about 10 kilometers and 7 kilometers respectively. It has a dark black color as a whole, and is mainly composed of iron, silicon, carbon, oxygen, etc.

And so it hit the Earth's atmosphere. At this moment, its surface turns red, releasing a dazzling light.

Its surface temperature climbed to thousands of degrees Celsius in an instant.

This process lasted only a few seconds. Because it's too fast, and the Earth's atmosphere is too thin.

In just a few seconds, it passed through the Earth's atmosphere. And at this moment, the bursting hurricane has been formed because of this violent impact. Under extremely high pressure, the wind spreads out to the surroundings at a speed of several kilometers per second.

Even the most powerful typhoon has a wind speed of only a few hundred meters per second. At this moment, the force of this strong wind is ten times greater than that of a typhoon.

Even the Iron Man will be blown to pieces in this area.

This wind alone is enough to wreak havoc on the earth's surface. But in the midst of this impact, it's just an appetizer, and it's not worth mentioning at all.

Later, the asteroid's foremost tip touched the Pacific Ocean, a five-kilometer by five-kilometer area with a total area of 25 square kilometers, numbered 110265.

This is the central point of impact. Outside of the central point, the asteroid is so large that it covers several of the remaining chunks around it.

The water in the center of the impact point was directly vaporized, and some of the debris of the asteroid was even thrown back into space because of this violent impact. Huge waves of kilometers high were generated and swept across the globe, and violent seismic waves also started from this and spread to the entire planet.

Geological weak spots, plate fractures, and an unprecedented earthquake destroys everything on the surface. Volcanoes begin to erupt, and winds begin to sweep around the entire planet. Mountains were blown down, trees were uprooted, tall buildings fell like toys, and thunderstorms and lightning began to appear in many parts of the earth because of the abundance of condensation nuclei.

At this moment, the earth has been ravaged hard enough. But that's just the beginning.

All kinds of drastic geological disasters will last for several years, and if they are to be completely calmed down, I am afraid that it will not be possible for hundreds of years. Violent storms will also become the norm, and the climate will deteriorate to the point where it is completely unsuitable for human life.

But that's still not the worst of all.

The most terrifying thing was that too much dust and ash were released into the sky as a result of the impact. They are so dense that they block out most of the sun. As a result, the earth has become cold, and even the equator, which is hot all year round, will be frozen for thousands of miles.

The entire ecosystem has completely collapsed, with more than 99.99% of species extinct. Large organisms other than microorganisms can even have extinction rates of up to 100% in the wild.

Only humans who have mastered advanced technology can survive in a small number of bases. But in the face of continuous natural disasters and harsh natural conditions, these people will all die in the next few years.

At the top left of the screen, that number finally goes to zero.

Director Wang whispered, "Ideally, well, it's the fourth year and 56 days since the impact, and the last human has died. Humanity is extinct. ”

That's the power of an asteroid impact.

Several people looked solemn.

Lu Ming knew that if he hadn't prepared in advance, didn't know in advance the location that would be least affected, and hoarded enough supplies there, built a suitable shelter, and placed enough suitable people, then, in reality, the outcome of human civilization would not be better than in this simulation.

In all likelihood, the Doomsday Organization is doing this right now.

"Hmm, the results of the first simulation are out."

At this moment, dense numbers appeared on the earth above the screen. They are all connected and completely invisible. Director Wang enlarged it, and Lu Ming could see clearly what those numbers were.

The number at the core of the impact point is 1000. Around the core point, it is 999, 998, 997, etc. They are densely connected, completely enclosing the entire core, occupying hundreds of chunks.

Obviously, these areas are slightly less affected than the core of the impact point. But that doesn't make sense.

It wasn't until more than a hundred kilometers away from the impact point that Lu Ming saw a number below 990. Numbers below 900 are found at a distance of more than 400 kilometers.

"This simulation, the place with the lowest rating, is here."

Director Wang dialed the image of the earth and pulled out a block in a desert more than 10,000 kilometers away from the impact point.

"Rated 34."

"Zoom in."

"Okay."

That block was zoomed in, revealing a fairly realistic image. So Lu Ming saw that the picture was shaking violently, and it took a long time to calm down.

"The magnitude of the earthquake was 6.2 on the Richter scale. Not too high. ”

An earthquake of this magnitude, if it were to appear in a densely populated city without warning, would be enough to cause tens of thousands of casualties. But for some purpose-built buildings, it's completely affordable.

But this earthquake is just the beginning.

Soon, Lu Ming saw the wind rising in the sky. The wind carried the yellow sand, obscuring the sky and the sun, and nothing could be seen.

After the yellow sand, a torrential rain appeared. In this place that has been dry for I don't know how many years, there was also a flood.

The torrential rain has reduced the yellow sand a little, and the clarity between heaven and earth has slightly restored. But the wind continued. At the same time, the sky was covered with dust, and the temperature plummeted, even to minus seventy or eighty degrees Celsius.

In addition to strong winds and low temperatures, there are also continuous aftershocks.

It is completely unsustainable.

It's not that people will freeze to death, starve to death, die of thirst, and so on if they are in such a place, as long as they appear in such a place without protection, the air alone is enough to choke people to death.

Lu Ming's expression was a little dark.

Such a harsh environment is still the best place on the earth for humans after being hit by an asteroid.

One can imagine how harsh the environment is in the rest of the place.

However, this simulation also verified Lu Ming's previous conjecture.

In this place that has been least affected, build a base with sufficient earthquake resistance level underneath it, as long as there are enough supplies in reserve, it can indeed support human beings to survive here.

Humanity has the technology to do this. There is no doubt about it.

The smoke and dust released into space by the impact of an asteroid will slowly dissipate with the passage of time. The structure of atmospheric elements will also be improved over time. Eventually, the sun will return to the land, the temperature will slowly rise, and the ice will gradually melt.

All of this may only take a few years.

As long as this underground base survives for several years, the external environment is enough to support the unprotected survival of human beings. In some places where the conditions are better, it can even be planted.

In this way, human civilization will slowly recover. As long as there is scientific planning, it is not impossible to reproduce enough people, reoccupy this earth, and restore it to its heyday state.

However, how to survive this period of harsh environment is the biggest problem.

The key to solving this dilemma is to determine which area of the earth will be the least affected when the impact does come, so as to have the greatest probability of preserving this underground base.

The first simulation has ended. The process of the second simulation then began to be demonstrated.

This time, the asteroid crashed into a mountainous area. Then Lu Ming found that compared to such a violent impact, the overall impact on the earth, whether it hit the ocean, mountains, or plains, was actually not much different.

The end result is a global freeze, frequent earthquakes and volcanoes, and only a small number of human beings remain, and finally die out after a few years of survival in a harsh environment.

There was not a single exception.

And in the midst of this constant simulation, one block after another, which always scores extremely highly, emerged.

No matter where that asteroid ends up impacting, the impact will always be enormous.

At this moment, less than an hour has passed, and more than 300,000 simulations have been carried out. Two days later, more than 20 million simulations were completed.

Up to 510 million blocks, all the data generated in more than 20 million simulations is fed into the statistical program. Then, those with an average score of 60 or more are all directly excluded.

The second team was not idle during these two days. While the simulation was underway, several people contacted some construction experts, as well as meteorologists and geologists, to conduct another assessment.

The content of the assessment is how severe a natural disaster can be withstood by the base built underground with the power of human civilization. After the evaluation results, combined with the scoring model of the Asteroid Warning Center, it was concluded that the underground structures built by humans have a higher probability of surviving in various types of natural disasters with a score of no more than 50.

So, the Doomsday organization's underground base—almost certainly that base was built underground. Because if it had been built on the ground, it would have been discovered by humans a long time ago. And, in the face of the violent wind and rain that followed the impact, it was impossible for the buildings on the ground to survive. It is only possible to preserve it if it is built underground.

The rating of their underground base's resistance to natural disasters was set at 60 after discussion among several members of the second team of the operation.

Although the Doomsday Organization is in such a desperate need for high-level human intellectuals, this proves that their level of technology may not be very high, but it is inevitable that they will also have some abilities that humans have not mastered, so the members of Operation 2 have increased the resistance level of their underground base to 60.

Out of more than 20 million simulations, an average score above 60 clearly means that the area has some hard hazards such as geological instability, climate instability, vulnerability to surrounding areas, and susceptibility to flooding. Such places, no matter where the asteroid hits, are not suitable as a place to build an underground base.

As many as 510 million blocks, after the completion of this exclusion, the number has plummeted, leaving less than 20 million, corresponding to an area of about 20 million square kilometers.

Although this simulation is relatively rough, and the statistical methods and screening conditions are also relatively rough, and many possibilities with low probability are not ruled out, it can still be considered that the lair of the Doomsday Organization, the underground base that they call themselves the Ark, is more likely to be within the range of 20 million square kilometers.

But it's still too big. They are scattered throughout the globe, and it is not feasible to search these places completely.

Lu Ming pondered for a moment and said, "I think that oceans, lakes, rivers and other places can be excluded. ”

The basis for this exclusion is still that "since the Doomsday Organization needs high-level human intellectuals, their own scientific and technological strength is limited, even if it is stronger than that of humans."

Since the strength is limited, the possibility of building a base on the bottom of the sea, the bottom of a lake, etc., can be ruled out.

Zhang Dingshan said: "I agree. ”

He Wei and Lu Qingliang also agreed.

As a result, up to 70% of the blocks were excluded.

At the moment, there are still 6 million blocks left, corresponding to 6 million square kilometers of land area.

Lu Ming manipulated and marked the 6 million blocks on the earth image. As a result, a few people saw that these 6 million blocks were like sand, scattered bits and pieces on the earth.

Small, with only a few dozen blocks connected together. The big ones are only about 3,000 blocks at most. In this way, it is divided into more than 70,000 places on seven continents.

From 510 million square kilometers of the total area of the earth, it has been reduced to 6 million square kilometers at the moment, and the target has been reduced by a total of 85 times.

But......

It's still too big to be fully searchable.
