Jiang Bo's eyes narrowed slightly: "Is the situation true?"

Zeng Wenhe said: "It is true, through tens of thousands of deductions on the quantum computer, it was found that there are five asteroids with a probability of more than 90.5 hitting the earth within a week, and one of the asteroids has a diameter of 4.2 kilometers!"

The result of the quantum computer deduction is that the asteroid has a 100% chance of hitting the Earth because of its large mass, and there is a 99.99% chance that it will fall in the shallow waters of the Gulf of Guinea, and only a 1 in 10,000 chance that it will fall into the deep Atlantic Ocean. ”

Zeng Wenhe said in a deep voice: "Once this asteroid hits the shallow water area of the Gulf of Guinea, it will cause an impact crater with a diameter of more than 30 kilometers, and within a radius of 500 kilometers, all the 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 the sea water to evaporate, rocks, mud and countless sulfuric acid substances will be vaporized, and the speed of more than ten kilometers per second will rush into the sky, and then form a global climate change.

This was followed by earthquakes, tsunamis, volcanic eruptions, and even large-scale movements of land plates and the melting of icebergs at the poles.

It is conservatively estimated that this disaster will cause the global population to plummet by more than one billion, and although China is far away, the global climate change, volcanoes, tsunamis and earthquakes will cause immeasurable losses. ”

Jiang Bo was shocked to hear that an asteroid with a diameter of 4.2 kilometers caused such a powerful asteroid.

After being surprised, Jiang Bo's brows couldn't help but furrow deeply.

He asked, "Why does the gravitational pull of the asteroid belt occur abnormally, have you found out?"

Zeng Wenhe: "We have some inferences, but we don't know if they are correct.

The gravitational anomaly, apparently attracted by massive objects, and the subsequent inexplicable disappearance of some asteroids, also confirmed this hypothesis, but images from the Sky Survey space telescope showed that there were no visible objects in that area.

So we deduce that there was a small mass black hole that passed 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 capture of gamma rays by NASA's space gamma-ray detector also indirectly proved the existence of black holes.

It is because the black hole captures and eats asteroids as it passes through the asteroid belt that it emits large amounts of X-rays and gamma rays. ”

Zeng continued: "However, based on the available astronomical data, we have found that such a small mass black hole is almost non-existent, 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 not more than 10 kilometers.

Its mass is the size of several Earths, which is too small for a black hole.

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

Even a celestial body as huge as the sun, when it runs out of fuel, it is impossible to form a black hole, because the mass is too small and the gravitational force is not enough!"

Jiang Bo was surprised: "Isn't it impossible? I have read some works on this subject before, and I also have some understanding of this, if a very small black hole formed when a star dies, it is only a few times the mass of the sun.

In a region with a relatively high degree of nothingness, there is no object around to eat, and it itself emits radiation, and its mass decreases, so that in billions or tens of billions of years, it will not become a black hole with a small mass?"

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

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

So this black hole emits less radiation than it absorbs.

In this case, if the universe continues to expand, the temperature of microwave radiation will need to wait 66 0 years after 1 to be lower than the temperature of the black hole, and the black hole will emit radiation and lose mass.

Therefore, in the current cosmic context, it is almost impossible for the mass of black holes formed by the collapse of stars to decrease, and they will only get bigger. ”

Jiang Bo: "You're a bit esoteric, but under normal circumstances, you can't form a small mass black hole, but maybe there are special circumstances?"

Zeng Wenhe was stunned: "Special circumstances?"

He has always considered within the scope of rational observability, and has not thought about special cases.

Zeng Wenhe's eyes suddenly lit up slightly: "Don't say it, after you mentioned it like this, boss, I am a little enlightened, under special circumstances, if you consider the early days of the Big Bang, when the pressure was high, the primordial black hole formed is not impossible to appear with a small mass."

The smaller the mass of the black hole and the higher the temperature, the more radiation will be emitted, and the mass will be lost.

As long as it is maintained at a relatively stable level, it is indeed possible that a low-mass black hole will appear more than 10 billion years later. ”

And the celestial body that passed through the asteroid belt, if it is a black hole, is nine out of nine is the primordial black hole.

Yes, yes, it's right in theory and in fact, boss, you're really ......."

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

Zeng Wenhe: "No, the black hole is almost chamfered to the asteroid belt, there is no angle to the earth, and the speed of this black hole is extremely fast, and it will not stay in the solar system for more than a month.

Alas, this is the primordial black hole discovered and observed by mankind, this black hole is not very massive, if it can be captured, it will be a natural energy reservoir.

With a massive object to pull it around Mars, even if there is no nuclear energy and the sun in the future, mankind will not have to worry about running out of energy.

It's a pity that the speed of this primordial black hole is too fast, and even if it is captured, humans currently do not have the means to convert radiation into usable energy.

It's a pity, it's a pity. ”

Skip Zeng Wenhe's words of regret.

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

Zeng Wenhe: "No, it's not just that, it's five!"

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

Zeng Wenhe: "At present, the five asteroids are 1.62 astronomical units away from us, about 243 million kilometers, and at their current flight speed, if they do not encounter a meteorite on the way, it will take about 110 days for the first asteroid to reach the earth." ”

Jiang Bo: "In other words, there are more than three months left?"

Zeng Wenhe: "That's right, on July 11, the first asteroid will collide with the earth, but the time of more than three months is fleeting, and in the face of five high-speed asteroids, even one with a diameter of 4.2 kilometers, it is too difficult to stop them from hitting the earth." ”

Jiang Bo: "Is it difficult?

Zeng Wenhe: "That's right. ”

Jiang Bo: "Has this news been announced to the outside world?"

Zeng Wenhe: "No, we don't dare to publish the news at will until we have used the quantum computer to check and get accurate results many times, on the one hand, for fear of causing unnecessary panic, and on the other hand, we are afraid of making mistakes and making oolongs." ”

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

Zeng Wenhe: "Okay. ”
