Reborn Before the Apocalypse: My Backing is the Nation

Chapter 216 Earth Ship
All eyes were on Jiang Yang.

As Jiang Yang thought rapidly, he carefully chose his words: "The main difficulty we face now is how to prevent excessive solar radiation from reaching the Earth."

The solution of achieving this goal by building a barrier is not feasible; we do not have that kind of engineering capacity.

So, is it possible to increase the distance between the Earth and the Sun? We certainly can't do that with our own power alone, but that black hole can!

A hint of madness crept into Jiang Yang's eyes, and his voice grew louder: "Use the gravity of that black hole to fling our Earth out of the solar system! Leave the sun!"

This would increase the distance between the Earth and the Sun, reducing the amount of solar radiation received. Even if the Sun expands into a red giant, we could still survive!

At this moment, the huge conference room fell completely silent.

Regardless of their scientific background, whether they were scientists or administrators, everyone stared at Jiang Yang in shock, momentarily forgetting to breathe.

Using the gravity of a black hole, the Earth can be flung out of the solar system!

This this……

Putting aside whether it's even possible, who among normal people could, or would dare to, come up with such a crazy plan!
I'm afraid that before the idea even took shape in my mind, it was subconsciously rejected.

Only someone like Jiang Yang, who has experienced multiple life-and-death cycles and whose mindset is completely different from that of normal people, could come up with such a crazy plan.

But, but, is this plan really not feasible?
Before the attendees could express their opinions, Jiang Yang turned directly to Professor Lu Zhaoming: "I'd like to know, theoretically speaking, is it possible for that black hole to eject the Earth from the solar system?"

Professor Lu Zhaoming had previously organized simulations of black hole orbits, so he clearly has a deep understanding of this type of problem.

Faced with Jiang Yang's question, he almost instinctively entered a state of thought:
"The Earth's orbital speed is about 30 kilometers per second, and the Sun's escape velocity at that orbit is about 42.1 kilometers per second. To free the Earth from the Sun's gravity, an increase in speed of 12.1 kilometers per second would be needed."

Meanwhile, the black hole has a mass three times that of Earth, and its initial orbital velocity is 3.7 kilometers per second…

One set of data after another flowed from Lu Zhaoming's mouth, then spun wildly in his mind. A moment later, he abruptly stopped reciting, paused, and looked up at Jiang Yang:

"Although it has not been actually verified or calculated, theoretically speaking, it is entirely possible to use a black hole with a mass three times that of Earth to apply a speed increase of 12.1 kilometers per second to Earth, causing it to break free from the Sun's gravity!"

"Is it feasible in reality?"

What is theoretically feasible is different from what is actually feasible. What is theoretically feasible means that the trajectory and velocity of a black hole are exactly under ideal conditions.

In reality, that black hole has its own orbit and speed. Furthermore, it is constantly influenced by various celestial bodies within the solar system as it moves forward. The only influence we can exert on that black hole is the ability to determine "when to break its gravitational shield."

Professor Lu Zhaoming quickly replied, "It's not clear yet; we need to do a simulation."

"for how long?"

Professor Lu Zhaoming gritted his teeth and said, "4 days... no, 3 days!"

In the large conference room, only the questions and answers between Jiang Yang and Professor Lu Zhaoming could be heard one after another.

All the other attendees remained silent, seemingly processing the information from the conversation between the two.

Jiang Yang shifted his gaze from Professor Lu Zhaoming to the members of the decision-making and deliberation groups.

"Distinguished decision-makers and deliberative bodies, I would like to know, assuming we can truly achieve the continuation of civilization in this way, should we do it?"

The leader of the decision-making group slowly stood up, his eyes filled with determination: "For the continuation of civilization, we can bear any price."

If destroying the moon can ensure the continuation of civilization, then destroy the moon;

If civilization cannot continue without solar energy, then let's leave the sun.

Furthermore, if destroying the Earth would not affect the survival of human civilization, but instead allow us to continue, then destroying the Earth would not be out of the question!
A solar system without humans, a universe without humans, means nothing to us!

The meeting room remained quiet.

The participants did not voice any objection to the seemingly extreme remarks made by the head of the decision-making group.

He paused for a moment, then continued, "But the most crucial issue now is not whether we have the ability to control the orbit of that black hole to fling Earth out of the solar system, but whether we humans can survive and continue on a planet that has turned into an ice ball after leaving the solar system."

I need a more detailed and reliable simulation report.

Professor Lu, you are in charge of simulating the actual orbital data of the black hole to see if it is possible to pass through that black hole and eject the Earth out of the solar system.
Professor Sun, you are responsible for simulating the changes after Earth is ejected from the solar system, and assessing whether our civilization can continue without the sun.

Having made these two arrangements, he looked at the many attendees and asked, "Does anyone have any objections or additions?"

The meeting room remained silent.

"Then let's do it this way!"

Three days passed in the blink of an eye, and another meeting was held. The first to report to the attendees was Professor Sun, who was responsible for assessing the environmental changes after Earth leaves the sun and whether humans could survive on such an Earth.

"The process of the Earth moving away from the Sun is also the process of the Sun being affected by black holes and gradually expanding and brightening."

Within this dynamic equilibrium, the total solar radiation received by the Earth does not actually fluctuate too much.

In other words, there will not be a situation where the Earth rapidly cools and freezes after breaking free from the Sun's gravity; it will be a relatively slow process.

Our data shows that for at least the first 20 years, before the distance between the Earth and the Sun increased to about 90 billion kilometers, the environment on the Earth's surface was able to be maintained at the minimum level suitable for human activity.

We will have at least a 20-year buffer period.

But after that, the situation will begin to deteriorate rapidly.

His voice began to grow heavy: "The Earth's surface will gradually freeze completely, all oceans, lakes and rivers, all liquid water will turn into solid, and even the Earth's atmosphere will freeze completely."

The Earth's surface would become a vacuum, and without the protection of an atmosphere, massive amounts of violent radiation from the sun and interstellar space would be able to reach the surface.

The freezing of the earth's surface will also severely affect our extraction and utilization of various resources, and the efficiency of mineral utilization will drop to less than 1% of the current level.

All of humanity will be confined to underground cities, living like rats in the dark, and the resulting social and psychological problems are currently beyond our ability to assess.

In summary, whether we can make good use of the initial 20-year buffer period will be the key to the continuation of our civilization.

Even if we make good use of these 20 years and build sufficiently advanced underground facilities while the Earth's environment is still relatively good, the probability of our civilization continuing to exist is no more than 50%.

The main reason is that civilized activities require a continuous input of external resources and energy, and cannot rely entirely on advance reserves. Furthermore, changes in the Earth's environment have made the acquisition of resources and energy extremely difficult.

Please note that the above assumptions are based on the premise that in the near future, our technology will make rapid breakthroughs and we will master mature, large-scale controlled nuclear fusion technology in a short period of time.

The situation would be even worse if the technology remained at its current level, that is, inefficient and unable to be used on a large scale.

And most importantly…

Professor Sun paused for a moment before saying in a low voice, "Even if our civilization continues, we will not have the ability to change Earth's orbit in the foreseeable future."

We have absolutely no control over how fast the Earth will travel or where it will ultimately go.

This vast universe is a sea of ​​stars, and our Earth is a giant ship. We humans are microorganisms that live on this ship.

We can only drift along in this ship, on the vast ocean of stars, not knowing where we will go or what we will encounter ahead.

Even if this ship were to capsize at any moment, we could only follow this vessel of Earth and perish together in the sea of ​​stars.

He raised his head and looked at the attendees: "The environment in the solar system is stable, and we have long since adapted to this stability."

We have adapted to the sun rising in the east and setting in the west; the sun rises every morning and sets every evening.

We have adapted to the changing seasons: spring brings forth all things, and winter brings ice and snow.

We have adapted to the phases of the moon, to the ebb and flow of the tides, and even the menstrual cycles of women, who make up half of the population, are shaped by the moon.
Leaving the solar system, everything we know will cease to exist; the future holds only the unknown. Whether our civilization will thrive in this sea of ​​stars or be instantly destroyed, no one knows.

Jiang Yang knew that Professor Sun's assessment represented the most authoritative and accurate opinion in the entire scientific community.

They would consider countless factors and gather the opinions of countless brilliant minds before finally arriving at this conclusion with utmost care.

Their assessment results, however, did not seem very optimistic.

A shadow quietly fell over Jiang Yang's heart.

The head of the decision-making team did not express his opinion on the assessment results, but instead looked at Professor Lu Zhaoming.

"Professor Lu, what are your evaluation results?"

Professor Lu Zhaoming's expression was equally solemn.

"Just a little short."

He murmured repeatedly, "It was just a little bit short..."

If the black hole's orbit could be altered even slightly, or if its speed or mass were increased even slightly, we could achieve our goal.

but now……"
