Silently opening the file bag and taking out stacks of documents and explanations, the Chinese representative turned on the microphone, looked around at the polite smiles of everyone present, and then spoke, going straight to the topic without any courtesy.
"The problem of Bell's asteroid is very difficult. Without the reminder of "Time and Space Review", human civilization will definitely be hit hard. Even if we have three months and a portal that can enter and exit space at will, it will be difficult to solve this problem. not easy."
"Just now, the respected President of the Astronomical Union, Mr. Smith, has explained that the most difficult part of changing the orbit of the Bell asteroid is that its spin is very fast, and the centrifugal force has reached the critical value of its current mass."
"What's more difficult is that its internal structure is very loose. Once it is damaged by external forces, it is very likely to disintegrate. Then we humans will completely lose control of it, which is unacceptable."
"So, after detailed analysis, multiple considerations, and research by many experts, we have planned the following plan."
As she spoke, the female representative opened the first page of the document and projected it on the big screen: "Please look at the big screen."
In the conference hall, everyone raised their heads and looked at the big screen seriously.
"The name of this plan is - Reverse Yarkovsky."
As soon as the words fell, suppressed whispers sounded in the hall.
The female representative ignored everyone's comments and continued: "The Yarkovsky effect, simply put, refers to the tiny push force that asteroids produce on stars when they absorb sunlight and release heat. All professionals present , I won’t go into details.”
"Your representative, I have a question." A blond researcher raised his hand: "Do you want to set up solar reflectors on asteroids? Let the sunlight shine on the rock mass to reflect the kinetic energy of heat photons? But this kind of The approach is too slow and we only have three months to go before we have time to realize the power of this effect."
"That's why it's called reverse Yarkovsky." The female representative smiled: "The momentum of the heat photon is too weak, so we don't use the momentum of the photon, we only need its heat."
"The main body of the plan is as follows. Set up a reflector with a radius of more than fifty meters to focus the sunlight on the axis of the asteroid's spin, heat the rock mass, and cause gas ejection."
Everyone at the scene stopped talking, and many people picked up their computers and started calculating.
"The continuous ejection of gas will bring continuous acceleration to the asteroid. After analysis and calculation by our three teams, if everything goes well, in three months, the Bell asteroid will pass by the earth. This distance It’s 190,000 kilometers.”
"190,000 kilometers..."
The host of the meeting frowned and thought deeply. After a moment, he asked: "Has the Earth's gravity been included in the calculation? Have the parameters been corrected?"
"It has been calculated." The female representative nodded: "My assistants will send the detailed data to everyone's terminals."
The person in charge frowned deeper, stretched out his index finger and tapped his forehead hard: "What about enhancement? Is there an enhancement plan?"
"Yes, please look at the big screen." The female representative opened the document to the second page: "The most appropriate enhancement plan is to deploy the solar reflector and match it with 130 laser emitters. When the structure of the Bell asteroid is stable, Down, the laser is emitted at a frequency of one-fifteenth of a second to enhance gas emissions."
"There are several other conventional heating methods, but they are difficult to control and may cause the asteroid to disintegrate."
After finishing speaking, the female representative spread her hands: "The only angle we can find is to push the asteroid forward. This is the safest and most stable way. As for the problem of Bell being torn apart by gravity when it gets close to the earth, it cannot be avoided. We can only rely on it. I hope the plan works well and can be pushed far enough.”
"Enough!" The person in charge stood up with bright eyes: "The spin problem of the Bell asteroid is too difficult. It is not easy to push it down 90,000 kilometers away. But..."
"but what?"
"Simple reflective heat energy isn't that great. Do you want to smear oil on the asteroid?"
"Yes, applying oil is the most important step." The female representative nodded: "Three days ago, we had contacted British Nano Company and jointly developed a special paint with a light absorption rate of 99.965% for painting On the surface of an asteroid.”
"So..." The person in charge suddenly shook his hands: "We want the Master of Time and Space UP... to paint?"
As soon as the words fell, the conference hall fell into silence.
"..." The female representative looked down at the document and corrected: "To paint a lot of paint..."
…
"I'm fully armed! I have a lightsaber, a protective suit, and I almost removed the cannon barrel of the island-building ship, but you tell me to paint it?"
A week later, in the Purple Mountain Observatory Square, with more than nine million viewers watching, Chen Yu looked at the person in charge in front of him with shock on his face.
"I'm sorry, Mr. Wang." The middle-aged person in charge bowed repeatedly: "Due to the special characteristics of the Bell asteroid, no weapons can be used to attack it unless necessary. Only by pushing the rock mass through the heating method of the Yarkovsky effect can the Safely changing the orbit of an asteroid."
"But..." Chen Yu stretched out his hand, pointed at the oil drums piled up in the square, and roared: "Isn't this too much? How long will it take to clean up?"
"The diameter of the Bell asteroid is six kilometers, and the area near the axis is very small." The person in charge wiped the sweat from his forehead and stretched out two fingers: "You can only brush two kilometers at most..."
Chen Yu: "..."
"Or...or a little more..."
"...Isn't there a very majestic plan, like the plot of a heroic movie?" Chen Yu stretched out his hands and tried to describe the picture in his mind: "Experiencing danger, hardship, hard work and wisdom, saving the world in the spotlight, cheering , shouting, applause, and flowers showering on your face, isn’t there a plan?”
"No...no..." The person in charge swallowed and said bravely: "You said it was a movie. Now...in reality, we only focus on efficiency and effect."
[Hahaha, laugh to deathヽ(≧≦)]
[I am a painter with strong painting skills]
[I saw at least a hundred barrels of paint.]
[I feel sorry for the owner of UP for a second.]
[Red and fiery roaring hahaha... ]
[I just realized it’s six kilometers in diameter! Ward day!]
[It seems to be spinning too fast and cannot be touched, otherwise it will disintegrate.]
[Bell: Try touching me? He exploded on the spot.]
[But painting is too silly, right? Is there really such a way to intercept asteroids?]
[never heard of that.]
[The plans formulated by professionals are definitely more effective than those fabricated by the media.]
Turning his head and looking at the densely packed paint buckets, Chen Yu refused to give up: "Is there really no other plan?"
"Mr. Wang, no more."
“…”
Three minutes later…
Chen Yu was holding a big brush on his left shoulder and a paint bucket in his right hand. He stood in front of the portal, reluctant to take a step.
"Mr. Wang, time is tight, let's start now." The person in charge, leading a large group of staff, experts and professors, bowed and said, "We will transport the oil barrels for you here."
"Mad! This picture of saving the world is not epic at all..."
Cursing, Chen Yu stepped through the portal and rushed towards the gray-green Bell asteroid...

There is only one chapter left in tonight’s extra update.
We have to admit that there are ups and downs in status, so continue coding and try to get back to the fifth update tomorrow!
