The Science Fiction World of Xueba

Liu Xin said: "Professor Pang, in this case, please explain your thoughts!"

Pang Xuelin said: "In fact, this method is not difficult to say. The reason why we are difficult to detect asteroids with a diameter of less than 500 meters is that the main reason is that these asteroids have lower apparent magnitudes. The larger the brightness, the darker it is. For humans, the sun has the highest apparent magnitude, -26.7, followed by the full moon, -12.6). It has a weak ability to reflect sunlight, and it is not strong to reflect radar waves. But We can try to enhance the signal feedback capabilities of these asteroids. For example, we can create large-scale artificial interstellar dust clouds in the 10 million kilometers of space near the earth ’s waterways. These interstellar dust clouds have strong electromagnetic wave reflection characteristics. When an asteroid passes through an interstellar dust cloud, it will feed back a strong electromagnetic wave signal. The asteroid with a diameter of ten meters can even increase its signal value by more than 100 times. "

"In this case, as long as an asteroid passes through the interstellar dust cloud, a clear trail can be left in the space of the universe. This is like when people walk on the snow, they leave a clear trail of footprints, so I call this This project is a snow project! "

Xi Pang Xuelin's words fell, and the entire conference room was quiet for a little while, and soon fell into a noisy state.

No one expected that Pang Xuelin proposed such a wonderful plan.

I won't say whether this solution has realistic feasibility. This idea alone is very valuable for discussion.

All of a sudden, there was a lot of discussion, and there was fierce debate over the feasibility of this plan. Some people supported it, and some opposed it.

欣 Liu Xin and Seedorf glanced at each other, flashing in surprise.

Liu Xin had to pat the table and said, "Quiet everyone, Professor Pang, I have a few questions about this plan. The first and most important point is what you said is used to create artificial interstellar dust. Cloud material, do we have such a material? Second, the range of the Earth passing through the asteroid belt is close to 200 million kilometers. The most dangerous flight segment is about 50 million kilometers. If you follow the minimum requirements of the snow project plan, We have arranged an interstellar dust cloud with a diameter of 10 million kilometers within the most dangerous 50 million kilometers of waterway. The required material is an astronomical number. Is the material reserve sufficient? Third, how to use these materials? How many spaceships need to be deployed in such a wide universe, have you considered these issues? "

The conference room became quiet again. Liu Xin was undoubtedly at the key of the snow project, and everyone focused on Pang Xuelin.

方案 The scheme he proposed is really clever, but the earth will cross the asteroid belt half a month later. It is really a big question whether human beings have time and ability to perform such a huge project.

Xi Pang Xuelin smiled slightly and was prepared for these issues.

"Secretary Liu, regarding the first question, I can tell you clearly that we have such a material, that is, metal-based graphene nanocomposites. This material has a strong electromagnetic wave reflection effect, and it is currently available in Jiangcheng The underground city is mass-produced. As far as I know, the factory's reserves have exceeded 200 tons. My idea is that we can wrap this material in a 100-ton equivalent hydrogen bomb, as long as the hydrogen bomb is delivered to the predetermined location After the hydrogen bomb explodes, each ton of metal-based graphene nanocomposite can form at least an interstellar dust cloud with a diameter of more than 100,000 kilometers. In addition, we do not need to arrange this dust cloud with the radius of the earth channel as the orbit of the asteroid in the asteroid belt With one-way consistency, we can arrange such interstellar dust clouds on one side of the earth's waterway. The only question now is whether we have enough hydrogen bombs and sufficient vehicles to drop the hydrogen bombs to the intended location. "

欣 Liu Xin's eyes narrowed slightly, he did not expect that Pang Xuelin had even considered the specific implementation plan of this project.

欣 Liu Xin said: "This question should be answered by General Bell Arnold, Commander of the Space Fleet."

He said, Liu Xin turned his attention to the middle-aged man in the space fleet military uniform sitting beside him.

Arnold said: "Professor Pang, I can tell you that our military has enough vehicles to deliver what you call metal-based graphene nanocomposites. As for the hydrogen bomb problem, I think flint is a suitable option. Our As long as the flint is modified, it can directly become a super hydrogen bomb with an equivalent weight of more than 100 million tons. In order to prevent problems with planetary engines, we have stored more than 20,000 flint, just take a small part of it With modification, it can meet the needs of snow projects. "

Pang Xuelin could not help but hesitate. Flint is a black technology that only appeared in the "Wandering Earth" movie. It is used to restart the planetary engine.

I just didn't say exactly what flint was in the movie. Someone on the Internet speculated that it should be a thermonuclear bomb to ignite the fusion planetary engine.

Pang Xuelin did not expect that this thing turned out to be a hydrogen bomb with an equivalent weight of more than 100 million tons ~ www.readwn.com ~ This is double the nuclear tsar equivalent of the nuclear bomb that the Soviet Union dropped on the Xindi Island nuclear range. It is almost comparable to the stellar hydrogen bomb in the three-body.

欣 Liu Xin said: "In this case, do you have any opinions on the snow project?"

The meeting room became quiet again, everyone looked at me, I looked at you.

Soon, one of the astrophysicists took the lead to state: "I have no opinion, Professor Pang's plan is indeed feasible. If this is successful, it can greatly reduce the risk of the Earth crossing the asteroid belt!"

"I have no opinion, this is a genius idea!"

"I have no opinion……"

Uh ...

Soon, everyone in the congregation expressed their opinions.

欣 Liu Xin said: "That being the case, then let's focus on the discussion of snow projects!"

Then, scientists began to discuss snow projects.

Xi Pang Xuelin just gave the general idea and feasible engineering scheme of this plan. The specific engineering details naturally require scientists to plan and calculate it in detail.

For example, the specific location of the hydrogen bomb, how to detonate, how to accurately calculate the asteroid's orbit through the metal dust cloud, what role the space fleet needs to play, and so on.

For these problems, naturally you do n’t need to go to Pang Xuelin anymore. The United Government has a large team of scientists and engineers who can come forward to solve these problems.

Squinting as the crowd in the conference room fell into a heated discussion, Liu Xin smiled and walked to Pang Xuelin with a smile, and said, "Xiao Pang, are you interested in talking with the old man?"

"my pleasure!"

Pang Xuelin nodded.
