Asteroid Crisis 2

Jiang Bo narrowed his eyes slightly: "The situation is true?"

Zeng Wenhe said: "It is true. Through tens of thousands of deductions by quantum computers, it was found that five asteroids had a chance of hitting the earth in one week. One of them had a diameter of 4.2 kilometers!

The result of quantum computer deduction is that because of its large mass, this asteroid has a 100% chance of hitting the earth, and a 99.99% chance of falling into the shallow waters of the Gulf of Guinea, and only one in ten thousand chance of falling into the Atlantic Ocean deep sea.”

Zeng Wenhe said in a deep voice: "Once this asteroid hits the shallow water area of ​​the Gulf of Guinea, it will cause a crater with a diameter of more than 30 kilometers. Within a radius of 500 kilometers, all buildings and plants on the ground will be destroyed by the scorching shock wave.

People can only survive by hiding in caves or underground bunkers, but this does not mean the end. The huge heat generated by the impact will cause seawater to evaporate, rocks, soil and countless sulfuric acid substances to be vaporized, rushing towards the sky at a speed of more than ten kilometers per second, and then forming global climate change.

Following this, there are earthquakes, tsunamis, volcanic eruptions, and even large-scale movements of land plates and the melting of icebergs on both poles.

Conservatively estimated that this disaster will sharply reduce the global population by hundreds of millions. Although China is far apart, the losses caused by global climate change, volcanoes, tsunamis and earthquakes are also immeasurable."

Jiang Bo was shocked when he heard this. The power of an asteroid with a diameter of 4.2 kilometers was so great.

After being surprised, Jiang Bo's brows frowned deeply again.

He asked, "Why does the gravity in the asteroid belt have abnormal imagination? Have you found out?"

Zeng Wenhe: "We have some inferences, but we don't know if it is correct or not.

The gravitational anomaly was obviously attracted by massive objects. Later, some asteroids disappeared inexplicably, which just confirmed this inference. However, the pictures sent back from the Space Telescope of the Skyscraper showed that there were no visible celestial bodies in that area.

So we infer that there was a small-mass black hole passing through the asteroid belt at that time.

This morning, news from FAST about the release of a large number of X-rays from the edge of the asteroid belt and the National Space Administration's space gamma-ray detector captured gamma-rays also indirectly proved the existence of black holes.

It is precisely because black holes capture feeding asteroids when they pass through the asteroid belt that they release a large number of X-rays and gamma rays.”

Zeng Wenhe continued: "However, based on existing astronomical data, we have found that this small-mass black hole almost does not exist through calculations, because the diameter of the event horizon of this black hole is less than 100 meters, and the gravitational capture range of the asteroid is no more than 10 kilometers.

Its mass is only the size of a few earths, which is too small for a black hole.

When it was formed from the death collapse of a star, how could its own gravity cause its matter to collapse inward? It is absolutely impossible.

Even a celestial body as huge as the sun will not be able to form a black hole when its fuel is exhausted, because its mass is too small and its gravity is not enough!”

Jiang Bo said in surprise: "Impossible? I have read some works on this before and have some understanding of it. If a star becomes a newly formed extremely small black hole when it dies, it is only a few times the mass of the sun.

It is in a relatively high-imperfect area, with no objects around it feeding, and it will emit radiation itself, and its mass will decrease accordingly. In this way, will it become a small-mass black hole in billions of years or tens of billions of years?"

Zeng Wenhe smiled bitterly and said, "No, radiation is related to temperature. The higher the temperature, the greater the radiation emissivity.

A black hole with a mass of several times the sun has a temperature of only one ten millionth of a degree, which is much lower than the temperature of 2.7K for the microwave radiation that fills the universe.

Therefore, the radiation of this black hole is less than it absorbs.

In this case, if the universe continues to expand, the temperature of microwave radiation needs to wait 1 for 66 years before it will be lower than the temperature of the black hole. Only at this time will the black hole emit radiation and lose mass.

Therefore, in the current cosmic context, it is basically impossible to reduce the mass of black holes formed by star collapse, and they will only become larger and larger."

Jiang Bo: "You are a bit profound, but under normal circumstances, small-mass black holes cannot be formed, but maybe there are special circumstances?"

Zeng Wenhe was stunned: "Special situation?"

He has been considering it within a rational observable range, but has never thought about special circumstances.

Zeng Wenhe suddenly had a lit up in front of him: "Not to say that, after you mentioned this, I was a little enlightened. In special circumstances, if you consider the early stage of the Big Bang and when the pressure is high, the Taichu black hole formed is not a small-mass black hole.

The smaller the mass of a black hole and the higher the temperature, the more it will radiate and the mass will be lost.

As long as it remains at a relatively stable level, it is indeed possible that small-mass black holes will appear in more than one billion years."

If the celestial body passing through the asteroid belt is a black hole, ninety percent of it is the Taichu black hole.

Yes, it's both theoretically and in fact. Boss, you really..."

Jiang Bo waved his hand at him and did not discuss the formation of a small-mass black hole with Zeng Wenhe. He was more concerned about the issue of the earth: "I want to know, will this black hole hit the earth?"

Zeng Wenhe: "No, the black hole and the asteroid belt are almost circular and tangential, and there is no angle to rush towards the earth. The speed of this black hole is extremely fast and will not stay in the solar system for more than one month.

Alas, this is because humans discovered and observed a black hole in the primeval area. The black hole has a small mass. If it can be captured, it will be a natural energy library.

Then use a large-mass object to pull it around Mars. Even if humans do not have nuclear energy and the sun in the future, they will not have to worry about energy exhaustion.

It’s a pity that this Taichu black hole is too fast, and even if it is captured, humans do not have a good means to convert radiation into available energy at present.

What a pity, what a pity.”

Skip Zeng Wenhe and express regrets.

Jiang Bo breathed a sigh of relief: "In other words, the only issue we need to consider now is that asteroid with a diameter of 4.2 kilometers?"

Zeng Wenhe: "No, it's more than that one, it's five!"

Jiang Bo: "How much time do we have left now?"

Zeng Wenhe: "The five asteroids are currently 162 astronomical units away from us, about 243 million kilometers. According to their current flight speed, if they have not encountered meteorites in the middle of the journey, the first one will take about 110 days before they can reach the earth."

Jiang Bo: "That is to say, there are more than three months left?"

Zeng Wenhe: "Yes, on July 11, the first asteroid will collide with the earth, but in the past three months, it's a blink of an eye. Facing five asteroids traveling at high speed, even one of them has a diameter of 4.2 kilometers. It's too difficult to stop them from hitting the earth."

Jiang Bo: "Difficult? Don't you do it?"

Zeng Wenhe: "That's right."

Jiang Bo: "Is this news informed to the outside world?"

Zeng Wenhe: "Not yet, before using quantum computers to verify the accurate results, we dare not publish the news at will. On the one hand, we are afraid of causing unnecessary panic, and on the other hand, we are afraid of making mistakes and causing a mistake."

Jiang Bo: "Then don't tell the outside world first, just pass the news to Director Tan and let them make the decision."

Zeng Wenhe: "Okay."
