"Wrapping nuclear material with conductive material?" A scientist next to him seemed to have guessed Hu Feng's train of thought, and his eyes lit up a little as he asked.

It stands to reason that neutrons are not charged and protons are positively charged, so nuclear materials should also be positively charged.

However, after actual testing, the nuclear material of the blue people is indeed invisible.

Human beings speculate that the nuclear materials of the Qinglan civilization should have used a special technology to use the chargeability of protons as the connecting bond between matter, so this situation was caused.

Obviously, the non-electrostatic nuclear material cannot be accelerated by electromagnetism, so if you want to launch the nuclear material with a mass cannon, you can only use conductive materials to carry it.

"Yes, there are 5 nuclear spheres in the wreckage of the battleship of the Blue Civilization, on which we can wrap a layer of conductive material for electromagnetic acceleration, and then set the program to carry out conventional acceleration in the early stage and overload acceleration at the last moment.

In this way, even if the conductive material disintegrates under overload acceleration, the nuclear material can withstand it, and the conductive material has already transferred most of its energy to the nuclear material in the process of disintegration. ”

Hu Feng picked up a notebook, wrote a string of data and material disintegration coefficients of human mass projectile materials, walked up to Lin Meng and said, "Professor Lin, help calculate these formulas, and then import the calculated results into the acceleration function of the mass cannon, and see how much the speed of the mass projectile can be increased by using this method?" ”

The disintegration of matter at high speed does not mean that too high speed will cause the matter to collapse, but it should be said that the acceleration overload will cause the matter to collapse.

Speed does not cause matter to collapse, even if it is infinitely close to the speed of light.

Usually it is said that the speed is too fast and causes a crash, which is caused by too fast acceleration.

It's like a rocket accelerating, and it's okay to spend dozens of minutes accelerating to the first cosmic velocity into space.

But if it accelerates to the first cosmic velocity in a second or two, the rocket will directly disintegrate and perform a grand celestial maiden scattered flowers.

Daily driving to 200 kilometers feels like the car is floating, the window glass is vibrating and seems to be falling apart, it should not be said that the speed is too fast to make the car unbearable, to be precise, it should be the air resistance to make the car unbearable.

In addition, the substance does not collapse with a bang under the overload, and such a manifestation is a causal weapon, not an overload exceeding the limit.

The collapse of matter in ultra-limit overload is an evolutionary process, which is like the separation of five horses, not that you will split the body as soon as the horse runs, but that there is a pulling process in the middle.

First, the rope is straightened, and the pulling force acts on the human body, and then beyond the limit of the human tissue, the tissue begins to tear, and then completely shredded...... If you have a high-speed video recorder, this process can be recorded perfectly.

Mass bullets require a solid spherical type, which is for balance and accuracy of launch.

If it is not a solid spherical type, it will cause an imbalance in the energy of the mass elastic when it collides with interstellar dust, resulting in an imbalance in the mass elastic force and tearing itself apart or changing direction slightly.

"With this approach, an accelerated orbit of 73,000 kilometers can be accelerated to 148,000 kilometers." With the support of huge computing resources, Lin Meng evolved the equation and calculated the result in a few minutes.

148,000 km...... This is not enough.

"What about the circumlunar mass cannon in this way?" Zhang Qing walked over and asked anxiously.

"199,800 kilometers per second."

The higher the speed of the mass projectile, the more difficult it is to accelerate, and the method proposed by Hu Feng is only to accelerate at the end of the explosion, and it is not about the acceleration of the front, middle and late stages, so it can be increased by almost more than 40,000 kilometers per second, and the mass cannon around the moon can be increased by 9,800 kilometers per second.

148,000 km and 199,800 km, the formula v=(v1+v2)/(1+v1v2/c^2)= 261,900 km.

Not enough!

"Can you increase the energy output and increase the acceleration at the end?" A scientist next to him asked anxiously.

"This is the highest energy output, and there is a limit to the acceleration." Zhang Qing shook her head, her eyes quickly dimming.

There is an upper limit to speed, and there is also an upper limit to acceleration.

The upper limit of the speed is the speed of light, and the upper limit of the acceleration is the allowable energy value of the Hilbert space.

In 1984, Caianelo derived the formula for the upper limit of acceleration of mass particles, a≦2(mc?? /h）。

where a is the acceleration of the particle, m is the mass of the particle, c is the speed of light, and h is Planck's constant.

This upper limit of acceleration is determined by the fundamental rules of physics, which determine that there is an upper limit to the amount of energy a particle can receive per unit of time.

This image point is like the size of the cylinder of a car, two cars of the same weight, the acceleration effect of a car with a 2.0T cylinder hitting the accelerator is definitely higher than that of a 1.5T.

The 1.5T can increase the acceleration to 10 meters per second with one foot of throttle, and the 2.0T can increase it to 14 meters per second.

However, the basic rules of physics determine that the maximum cylinder cannot exceed 3.0T, so no matter how hard you press the accelerator, the acceleration cannot exceed 20 meters per second.

"If we squeeze the productivity of human beings, we can increase the orbit of the space mass cannon to 76,000 to 77,000 kilometers, and in this way, it can reach 263,700 kilometers per second."

A sociologist next to him turned out the latest data on human productivity and quickly shouted: "And the nuclear industrial bases of the former five major countries are already urgently producing nuclear bombs, and we can still produce a batch of nuclear bombs in these dozens of hours, and the time for electromagnetic interference to persist can be extended by about one hour."

In this way, we have more time to build an acceleration orbit that can be built longer, two mass cannons are fired opposite each other, and the collision of mass shells can break the space-time distortion of the fourth-level intelligent battleship! ”

As soon as these words came out, they were injected into the hearts of everyone present like a heart booster, and Zhang Qing even looked at Lu Yi.

"Lu Lu ......"

To change the plan and mobilize the productive forces of the entire human civilization, only Lu Yi has this authority among the people present at present.

"You can try."

In the eager eyes of everyone, Lu Yi was silent for a while and said: "But everyone goes to the starship first, and be ready to evacuate to the Human Ship at any time, the success rate of this method is less than 1 in 100 million." ”

"Why?" Everyone was stunned.

Looking at the people who had no time to rest except for intermittently squinting for more than ten minutes for several days, and their mental state and thinking had obviously dropped a lot, Lu Yi shook his head and said two words.

"Precision."

Precision, this is the most fatal point of this method proposed by Hu Feng.

When the end accelerates beyond the load, the conductive material collapses, leaving the core of the nucleon material to inherit the velocity and launch out.

In the process of the collapse of the conductive material, the core of the nuclear material will inevitably be affected, resulting in unpredictable subtle deflections.

The nuclear material left behind by the blue civilization is not electrically significant, which means that once the deflection occurs, humans cannot adjust it through technical means.

Such a deflection has little effect on the range at close range, but in space with a range of hundreds of thousands of kilometers, it is deadly.

Even if it is only deflected by one hundredth of a degree, it is impossible for these two mass bombs to collide with each other in the end, and it is impossible to break the fourth-level intelligent warship.

To make matters worse, after overloading acceleration at the end, the collapsing conductive material will eject and explode within the acceleration track, destroying the acceleration track.

The acceleration track of the mass cannon is not too technical, and it is easy to manufacture and repair, but humans have no time to repair it at that time.

In other words, there is only one chance to launch, a chance to launch with a success rate of less than 1 in 100 million.

......

The final plan was determined, and all the potential of human civilization completely exploded, and factories and equipment began to produce the accelerated orbit of the mass gun, the cooperative control scheme of the mass gun starship platform, and more than 100,000 people began to improve on the basis of the original starship system.

At this time, the people in the command center were idle, making up for sleep, connecting with their families, and walking alone to connect the memories of the time.

Everyone understands that in two days, they will probably leave the earth for eternity.

When the sun set, Lu Yi did not go to rest, but came to the roof to watch the sunset.

"Lu Lu, aren't you going to rest?"

Zhang Qing and Lin Meng, who had rested for a few hours, came to the roof and sat next to Lu Yi and looked at him with some concern.

"Can't sleep." Lu Yi smiled and shook his head, his eyes were a little fascinated when he watched the sunset in the sky.

People, who are always about to lose when they arrive, will wake up to the preciousness of everything they have in the past.

At this time, there are less than 24 hours left before the electromagnetic interference, and the time that nuclear bombs and electromagnetic pulse bombs can last is only 33 hours.

The weather forecast suggests that Yangcheng will be cloudy tomorrow and turn to moderate rain in the afternoon, which means that today's sunset is likely to be the last sunset Lu Yi saw on earth.

As night fell, the ambient air became better and better in the past two years, the stars twinkled in the deep night sky, and the large moon hung in the sky and sprinkled the bright moonlight.

In the distance, fireworks are blooming in the sky, reflecting the beauty of the world.

"Today seems to be the Mid-Autumn Festival."

Professor Lin looked at the brilliant fireworks for a while, and suddenly said, "My mother called me in the morning, and I hung up before I could say a few words when I was busy." ”

"Now video with Mom?" Lu Yi reached out and touched Lin Meng's hair, and took out his mobile phone to her.

"Nope."

"Mom knows that I'm busy, and I don't usually have any time to rest, but she just called me in the morning and I'm calling back, she is more sensitive and will think wildly."

Professor Lin bit his lip and shook his head, his eyes suddenly turned red: "I just don't want to leave, I'm afraid I'll miss them in the future......"

Before Lin Meng's words could speak, tears poured out, and Zhang Qing, who was on the other side, couldn't suppress her tense emotions for a few days at this time, and the tears were silently left.

There used to be a very controversial issue on the Internet, when the end came, only tens of thousands of human beings could survive and escape to the stars on a warship, at this time you have a ticket, do you choose to leave or choose to stay?

Stay, and sleep forever on Earth with 7 billion compatriots.

Boarding the ship, carrying the hope of the entire civilization, carrying the future, and carrying the mission of inheriting civilization, always under great pressure, always bearing loneliness, longing, confusion, and despair, and launching an unknown dark star journey in the starry sky.

Everyone has their own answer in their heart.

Lu Yi didn't coax him, just looked at the endless fireworks in the sky with red eyes, and reached out to hug Zhang Qing and Lin Meng, who were crying silently.

The night was getting deeper, and Zhang Qing and Lin Meng had tears on their faces, and they were already leaning on Lu Yi and falling asleep.

Woooooo

A few kilometers away from the railway line in the laboratory area, a freight train suddenly sounded its whistle, as if it had noticed something in front of it.

The sound of the whistle spread far and wide in the silent night, waking up pieces of sleeping dreams, so that the security personnel took a coat and was about to cover Zhang Qing and Lin Meng, Lu Yi, was suddenly stunned when he heard the whistle.

Whistle? Rail!

Lu Yi seemed to have thought of something......
