For twenty-seven days, Du Xingyu was thinking about a plan to make the asteroid change its orbit!

    This requires a super large force to act on it in a certain direction and make it deviate from its existing orbit.

    With human technology, only hydrogen bombs can produce so much energy! Moreover, more than one hydrogen bomb with the explosive power of more than 170 million tons of TNT, such as the Soviet czar bomb, is only tickling in front of this high-speed high-mass asteroid.

    Adding up all the nuclear warheads owned by humans on earth, the power seems to be a little poor, and the most difficult thing is that these explosions still need to be carried out in space, focusing on a few force points of asteroids in a short time

    Even if the asteroid is really blown up, the debris of the asteroid will form a huge meteorite rain. Each giant meteorite is enough to destroy a human city, so blowing up is not an ideal scheme.

    On the science and technology simulator, Du Xingyu has created a new science and technology research and development column - asteroid impactor.

    Under the asteroid impactor, there is a blank for the time being. Because Du Xingyu has insufficient data at present, he needs to know the mass, accurate speed and orbital direction of the asteroid, so as to calculate the kinetic energy that the asteroid impactor needs to give and push backward step by step.

    "The asteroid impactor must be launched at a distance away from the earth, otherwise it will still be dangerous, and the ideal launch site should be Mars." Du Xingyu continued to calculate along this idea.

    "Then Mars needs a space launch station, and humans also need to send a large number of masses and nuclear warheads to Mars... In addition to asteroid impactors, we also need a space defense system as the second layer of defense..."

    Du Xingyu found that this is definitely a big project. Only with the joint efforts of all mankind can there be so little hope.

    To create asteroid impactors and supporting space defense systems, humans must first provide space transportation capabilities.

    It is imperative to build a spaceport in this way; Then there are space warships, Mars military bases and so on.

    No country has the strength to complete each project independently, and if we want to build these projects within 20 years, we should not consider economic benefits and spend our lives.

    ……

    Time passes day by day. Tomorrow is the Nobel prize awarding ceremony. Du Xingyu is going to Stockholm, Sweden. At that time, the king of Sweden will present the Nobel Prize winners in person.

    "Academician Wang." before leaving, Du Xingyu found Wang Qing and said, "I''ve bothered you at the observatory these days. My research has finally yielded some results."

    "What achievement?" Wang Qing said strangely.

    Du Xingyu has been observing Neptune and the Kuiper belt, but no one knows what he found.

    What puzzled Wang Qing was that Professor Beth of Haleakala Observatory, who had been in contact with Du Xingyu, was insane.

    "It''s all in this encrypted USB flash drive." Du Xingyu handed him a USB flash drive and said, "the things in it are very important. I''ll give it to you. When I arrive in Sweden, I''ll send you the password and you can open it."

    "What? It''s like acting in a movie." Wang Qing was even more confused. Du Xingyu was going to attend the award ceremony, not to fight. Why?

    "I''m leaving!" Du Xingyu handed Wang Qing the USB flash drive and turned away. Outside, his bodyguard Yue Chen and Secretary Shangguan Zihan are ready. A special plane will pick him up to Sweden to attend the Nobel Prize ceremony.

    After Du Xingyu left, Wang Qing was wondering what was in the encrypted USB flash drive left by Du Xingyu. He wanted to open it immediately.

    Capital time is six hours faster than Swedish time. When Du Xingyu arrived at the Royal Hotel in Stockholm, Sweden, it was already 9:00 midnight local time.

    The Swedish Royal family sent a royal protocol minister to receive him personally.

    "Mr. Du, you are very busy. Your majesty doesn''t want to bother your guests at this time, so please stay in the hotel temporarily. Tomorrow, your majesty will give you awards and hold a dinner." the Minister of protocol said respectfully.

    Du Xingyu''s name has long been spread all over the world. Everyone knows that this young man brought China into the space age at one stroke. He is a figure with the ability to change the world. Therefore, even the traditional aristocrats in Europe respect him very much.

    "Thank you for your kindness, and I''m looking forward to seeing your majesty," Du Xingyu replied politely.

    At the moment, China is 3 a.m. at the Licheng observatory.

    If it were normal time, Wang Qing would have fallen asleep. But Du Xingyu''s words before he left yesterday made his heart itch and couldn''t sleep over and over.

    At this time, Du Xingyu sent him a string of passwords, which is the key to unlock the USB flash disk.

    "Finally, it''s come. Xiao Du has tortured me all day!" Wang Qing couldn''t wait to unlock the USB flash drive and check the contents.

    "It''s all astronomical observation images and data. Has he found a new celestial body?" Wang Qing wondered. He called the night shift students of the two observatories to compare and calculate these data together.

    Two hours later.

    "This... How is this possible?" Wang Qingyue was more and more frightened. He realized that Du Xingyu might have found a terrible truth!

    "Teacher, I have calculated the light change data near Neptune for seven consecutive days..." a student said. "It can be concluded that a KBO (Kuiper belt) object has changed its orbit by Neptune''s gravity and is flying to the interior of the solar system!"

    "Teacher, its orbit direction intersects with the earth''s orbit! Its flight speed is expected to reach the earth''s orbit in 20 years." another student''s voice is a little frightened. "According to the calculation, it is bound to be attracted by the earth''s gravity and fly to the earth!"

    Wang Qing himself also calculated some data. He looked at the calculation results in shock and said in an unbelievable tone: "the diameter of this celestial body is about 30 kilometers. It is an asteroid! It is three times larger than the diameter of the asteroid that killed the dinosaurs!"

    "In other words, it will hit the earth!"

    "Teacher!" the two students looked at him with pale faces, "what should we do?"

    "What should I do?" Wang Qing also asked himself. The discovery was so shocking that it was more terrible than the news of the outbreak of the third world war!

    He can''t imagine what will happen once the news is released!

    Can humans stop the asteroid? Wang Qing can''t think of any way. Now humans can send at most a few people into space. In the face of such a world destroying star, I''m afraid there''s nothing they can do!

    "Teacher?" the two students have been completely flustered. When they know the news that the world will be destroyed in 20 years, even those with strong psychological quality will be at a loss!

    "So it is!" Wang Qingnan said to himself. He finally knew what Du Xingyu was observing, why he was so careful, and why Professor Beth went crazy. It turned out that they foresaw the end of mankind!

    He breathed deeply and tried to calm his mood. Even if it was the end of the world, there would still be twenty years, wouldn''t he?

    "You two!" Wang Qing looked at the two students with an extremely dignified expression. "From now on, don''t tell anyone about it! Don''t leave this room for half a step!"

    He paused for a long time, gritted his teeth and said, "I''ll report it to the top!"
