Paranormal incident investigation notes

Simulating the impact on every region of the world when an asteroid hits the Earth, as well as the interaction between the impacts, is a very complex matter. To simulate once, the computing power required is so high that ordinary people cannot imagine it.

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 Asteroid Warning Center, it would take two full days to complete.

During these two days, all scientific research tasks will be suspended. But fortunately, it will not affect the daily observation work at the early warning center.

Because if it is just observation, there is no need to use supercomputing.

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

He transformed Lu Ming's requirements into detailed and rigorous 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 supercomputers, this first simulation only took a few milliseconds. In order to let the operators feel the simulation results more intuitively, it takes up to half an hour to present them on the screen.

Then, Lu Ming saw a huge asteroid rushing towards the Pacific Ocean of the Earth in a relatively inclined orbit.

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

It hit the Earth's atmosphere. At this moment, its surface turned red, releasing a dazzling light.

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

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

In just a few seconds, it passed through the Earth's atmosphere. At this moment, a bursting hurricane had formed due to the violent impact. Under extremely high pressure, strong winds spread around at speeds of thousands of meters per second.

Even the most violent typhoons have wind speeds of only a few hundred meters per second. At this moment, the power of this violent wind is more than ten times stronger than that of a typhoon.

Even an iron man would be blown to pieces in this area.

The strong wind alone is enough to cause great damage to the surface. But in the whole impact process, this is just an appetizer, not worth mentioning at all.

After that, the front end of the asteroid touched the Pacific Ocean, in an area of ​​5 kilometers by 5 kilometers, with a total area of ​​25 square kilometers, and was numbered 110265.

This is the center point of impact. Beyond the central point, because the asteroid is so large, it also covers several other surrounding areas.

The water in the center of the impact point was directly vaporized, and some remnants of the asteroid were even thrown back into space due to the violent impact. Huge waves as high as a kilometer were generated and swept across the world. Violent earthquake waves also started from this point and spread to the entire planet.

At weak points in the geology, plates fractured, and unprecedentedly violent earthquakes destroyed everything on the surface. Volcanoes began to erupt, and strong winds began to sweep around the entire planet. Mountain peaks were blown down, trees were uprooted, and tall buildings fell down easily like toys. Because there were enough condensation nuclei, thunderstorms and lightning began to appear in many places on the earth.

The earth has been ravaged violently enough at this moment. But this is still just the beginning.

Various severe geological disasters will last for several years, and it may not take hundreds of years to completely subside. Severe storms will also become the norm, and the climate will deteriorate to the point where it is completely unsuitable for human survival.

But that's still not the scariest thing.

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

The entire ecosystem collapsed completely, and more than 99.99% of species became extinct. The extinction rate of large organisms other than microorganisms in the wild may even be as high as 100%.

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

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

Director Wang whispered: "In an ideal situation, well, it is now four years and 56 days after the impact, and the last human has died. Humanity has become extinct."

Such is the power of an asteroid impact.

Several people looked solemn.

Lu Ming knew that if he did not prepare in advance, did not know in advance the least affected location, and stockpile enough supplies there, build suitable shelters, and place enough suitable people, then in reality, the outcome of human civilization would be , will not be better than in this simulation.

——There is a high probability that the doomsday organization is doing this now.

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

At this moment, dense numbers appeared on the earth above the screen. They are connected together and cannot be seen at all. Manager Wang enlarged it, and Lu Ming could clearly see what the 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 covering the entire core and occupying hundreds of blocks.

Obviously, compared to the core of the impact point, the impact on these places is slightly smaller. But this is of no practical significance.

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 can only be found at a distance of more than 400 kilometers.

"The place with the lowest score in this simulation is here."

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

"Rating 34."

"enlarge."

"good."

That area was enlarged, showing a quite realistic image. Then Lu Ming saw the screen shaking violently, and it took a long time to calm down.

"The magnitude was 6.2 on the Richter scale. It's not high."

An earthquake of this magnitude, if unprepared, could cause tens of thousands of casualties if it occurred in a densely populated city. But for some specially designed buildings, it is completely within the affordable range.

But this earthquake was just the beginning.

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

After the yellow sand, heavy rain appears. This place, which had been dry for who knows how many years, actually had floods.

The heavy rain reduced the amount of yellow sand, and the sky and earth regained a little clarity. But the wind still raged. At the same time, the sky was covered with dust, and the temperature plummeted, even to minus 70 or 80 degrees Celsius.

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

This place is completely unable to support human survival.

This does not mean that people will freeze to death, starve to death, thirst, etc. if they are in such a place, but as long as people appear in such a place without protection, the air alone is enough to choke them to death.

Lu Ming looked a little sad.

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

One can imagine how bad the environment in other places is.

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

In this place that has been least affected, a base with sufficient earthquake resistance is built underground. As long as enough supplies are stored, it can indeed support human beings to survive here.

Humanity's existing technology can do this. There is no doubt about it.

The smoke and dust released into space due to asteroid impacts will slowly dissipate over time. The structure of atmospheric elements will also be slowly optimized over time. The sun will eventually shine on this land again, the temperature will slowly rise, and the ice will gradually melt.

All this may only take a few years.

As long as we survive these few years in this underground base, the external environment will be enough to support human beings' unprotected survival. In some places with better conditions, planting can even be done.

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

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

However, the key to solving this problem is to determine which area of ​​the earth will be least affected when the impact really comes, and which will have the greatest probability of preserving this underground base.

The first simulation has ended. The second simulation process then begins to show.

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

The end result will always be that the world is frozen, earthquakes and volcanoes occur frequently, and only a small number of humans remain. In the end, they survive in the harsh environment for several years and then eventually perish.

No exceptions.

And in this continuous simulation, one block after another that always scored extremely high emerged.

No matter where that asteroid ends up impacting, the impact is always huge.

At this moment, less than an hour has passed, and the simulation has been carried out more than 300,000 times. After two days, more than 20 million simulations were completed.

Up to 510 million blocks, all the data generated in more than 20 million simulations were input into the statistical program. Then, all those with an average score above 60 were directly excluded.

Operation Team 2 was not idle during these two days. While the simulation was in progress, several people contacted some construction experts, as well as meteorological and geological experts, to conduct another assessment.

The assessment content is how severe a natural disaster a base built underground can withstand with the power of human civilization. After the evaluation results are combined with the scoring model here at the Asteroid Warning Center, the conclusion is that underground buildings built by humans have a high probability of surviving various types of natural disasters with a score of no more than 50.

Therefore, the underground base of the Doomsday Organization - that base is almost certainly built underground. Because if it was built on the ground, it would have been discovered by humans long ago. Moreover, in the face of the violent wind and rain after the impact, it is impossible for ground buildings to survive. Only if it is built underground can it be preserved.

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

Although the Doomsday Organization is so urgently in need of high-level human intellectuals, this proves that their technological level may not be very high, but it is inevitable that they will also have some abilities that humans have not mastered. Therefore, several members of the Operation Team 2 took their underground The base's resistance level was raised a bit and set at 60.

Among more than 20 million simulations, a place with an average score higher than 60 obviously means that the area has some shortcomings such as geological instability, climate instability, vulnerability to surrounding areas, and vulnerability to flooding. Hidden danger. This type of place, no matter where the asteroid struck, is not suitable as a construction site for an underground base.

There were as many as 510 million blocks. After this elimination, the number dropped sharply, leaving only less than 20 million blocks, corresponding to an area of ​​approximately 20 million square kilometers.

Although this simulation is relatively rough, the statistical methods and screening conditions are also rough, and many possibilities with low probabilities have not been ruled out. At this moment, it can still be believed that the home base of the doomsday organization, the underground base they call themselves the Ark, has a high probability. It is within this 20 million square kilometers.

But the area is still too large. They are scattered scattered all over the earth, and it is not feasible to conduct a complete search of these places.

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

The basis for this exclusion is still that "since doomsday organizations need high-level human intellectuals, their own technological strength is limited even if it is stronger than humans."

Since force is limited, the possibility of building the base on the seabed, lake bottom, or the like can be ruled out.

Zhang Dingshan said: "I agree."

He Wei and Lu Qingliang also expressed their agreement.

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

There are still 6 million blocks left, corresponding to a land area of ​​6 million square kilometers.

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

Small, just a few dozen blocks connected together. For large ones, there are at most three thousand blocks connected together. It is so fragmented that it is divided into more than 70,000 places in total, spread across the seven continents.

The total area of ​​the earth has shrunk from 510 million square kilometers to the current 6 million square kilometers, a total target reduction of 85 times.

But……

It is still too big to be fully searchable.
