It's reasonable for me to have a two-way foil for a second-level civilization, right?

A few hours later, the group of jellyfish lined up and moved again towards the Kraken-Mare Sea.

Contrary to everyone's cognition, this group of new jellyfish has consciousness!

If Zhao Zijie saw this scene, he would definitely express a sigh of emotion!

'It's so terrifying to say what you say! '

But unfortunately, with the departure of Xuannv No. [-], this scene will definitely not be known.

Chapter 251 Venus falls into the sun, the bunker plan

two months later.

Jupiter.

On the huge orbit of Jupiter, dozens of [rays] silently absorb the helium-[-] resources in Jupiter's atmosphere.

Although humans have begun the evacuation plan, they still have to stick to their posts until the last moment.

Even a negligible one gram of helium-[-] is extremely important to the human fleet that is about to sail away.

……

The back side of Jupiter.

The fleet composed of 1251 Nebula-class starships silently adjusted their course, keeping themselves on the side of Jupiter facing away from the sun at all times.

In the fleet, there is a starship that is particularly eye-catching.

Its incomparably huge size and its position in the center of the fleet all show its unique status.

That is the flagship of human civilization: [Earth].

The [Earth], which inherited the flagship name of the previous generation, has a length of 2500 meters, which is a full 1000 meters longer than other starships.

As the saying goes, one inch is long and one inch is strong. As the flagship of human civilization, [Earth] naturally possesses unrivaled performance of other Nebula-class starships.

In addition to having an independent large-capacity material storage unit and an independent large laboratory, [Earth] has thicker armor, a more powerful power system, and a more powerful weapon system!

In addition, there are also a large number of biological gene samples stored in the [Earth].

It is no exaggeration to say that even if there is an accident in the human fleet, with the [Earth], human civilization still has a glimmer of hope for a comeback.

……

【Earth number】.

In the huge command center, there is an atmosphere of restlessness and restlessness.

Thousands of top scientists and starship pilots sat nervously in their seats.

Everyone's eyes are fixed on the huge holographic image directly in front of them.

In the holographic projection, real-time observation images of the sun and Venus are impressively presented.

The observation images are provided by observation satellites orbiting Jupiter, so there is a delay of about 43 minutes with the actual images.

"Zero, how much time is left before the impact?"

Lu Yongchang, who was standing on the podium, frowned and asked in a deep voice.

The huge holographic projection screen directly in front of him changed instantly.

A countdown is presented in front of everyone.

【00:48:36】

"Venus is expected to fall into the solar atmosphere in 48 minutes and 36 seconds." Zero's voice did not fluctuate at all.

"Only 48 minutes left?"

Lu Yongchang's face changed slightly, and after a moment of pondering, he said again: "Everyone, check the status of each starship again."

"This bunker plan, no mistakes are allowed!"

Time passed by one minute and one second, and the countdown was reset to zero.

"Professor, the fall of Venus has already happened."

Zero's flat voice sounded in the command center.

In the next second, the countdown on the holographic screen is refreshed again.

【00:42:45】

This is the countdown to when humans can observe the specific picture of Venus falling into the sun.

……

The countdown resets to zero again.

The holographic image has changed slightly.

It is very similar to the scene of Mercury falling into the sun, except that the whole scene is more grand and spectacular.

Under the deceleration effect of the sun's atmosphere, Venus was unable to maintain its original orbit, and fell straight towards the interior of the sun.

At this time, Venus has lost all its atmosphere, and like Mercury in the past, it has become a huge lava ball.

The moment it fell into the sun, the sun's corona was "smashed" out of a huge hole!

The brightness of the impact area increased instantly, and at the same time, endless coronal matter was ejected into space!

The power of Venus falling into the sun is obviously much greater than that of Mercury. The ejected coronal matter was even accelerated to escape velocity in a short period of time, and flew straight away from the sun!

"The solar storm is expected to arrive at Jupiter in ten days." Zero's reminder sounded just right, "With Jupiter's magnetic field 14 times that of the Earth, we can safely escape this solar storm..."

Lu Yongchang didn't pay attention to Zero's reminder, but just stared at the ejected coronal matter.

"Zero, don't worry about the solar storm."

There was a bit of nervousness in Lu Yongchang's voice: "Calculate, the trajectory of that mass of coronal matter!"

In just a few seconds, Zero gave the answer.

"Professor, according to the simulation results, these coronal materials will be deflected by Jupiter's gravity and eventually be captured by Jupiter."

Lu Yongchang held his breath subconsciously: "How long will it take?"

Not only Lu Yongchang, but every scientific researcher present held their breath, waiting quietly for Zero's answer.

"Calculation results show that the time of capture is five years later."

There was a sound of exhalation in the command hall.

"Scared me to death..." Fang Xu wiped the cold sweat from his forehead with his hand, "What happens five years later has nothing to do with us."

"That's right!" Cao Liangcai's voice sounded, "I guess we were all outside the Kuiper belt at that time, so why does Jupiter have something to do with us?"

"Academician Fang, you don't know, at that moment just now, cold sweat broke out on my back!"

Different from the relaxed appearance of everyone around him, Lu Yongchang still had a solemn and serious expression on his face.

"Zero, according to the situation of Venus falling into the sun, simulate the scene of the earth falling into the sun."

A few seconds later, a simulated picture of the earth falling into the sun appeared on the holographic projection directly in front of it.

Slightly different from Venus, when the earth fell into the sun, helium flashes erupted at the same time.

But the same is that the earth's fall into the sun also "smashed" a part of the corona material.

"Zero, roughly estimate, if all these coronal materials are captured by Jupiter, how much will its mass increase?"

This time, Zero "thought" for a few minutes.

"Professor, there are too many variables, and the calculation results will be quite different from the real situation."

"It's okay, just tell me a range." Lu Yongchang waved his hand and said, "No precise data is needed."

"Jupiter's mass will rise to between 5.11 and 23.17 times its current level."

The moment the zero sound sounded, the [Earth] command center was silent.

"Brown dwarf?"

Fang Xu's voice broke the silence of the command center.

"Yes, Academician Fang." Ling responded methodically.

"After Jupiter has increased mass, the probability of becoming a brown dwarf reaches 27.96%."

The so-called brown dwarfs are equivalent to incompletely developed stars.

Its mass falls short of the minimum threshold for becoming a star, but it is much heavier than the usual gas giants.

Unlike stars, brown dwarfs are not massive enough to sustain the nuclear fusion of normal stars, but they can undergo deuterium fusion inside.

Therefore, the surface temperature of brown dwarfs will be much lower than that of stars, generally not exceeding 3000K.

"27.96%, this probability is not low..." Lu Yongchang muttered to himself.

ps. To add, the magnetic field strength of Saturn is slightly smaller than that of the Earth, and the magnetosphere only extends beyond the orbit of Titan.

Chapter 252 Double Star System

"Yeah, the probability is not low."

Fang Xu's emotional voice came from the side: "I didn't expect the sun to leave a legacy to Jupiter when it was dying. Maybe in countless years, the solar system will become a binary star system!"

"Double star system..." Lu Yongchang frowned the moment he heard this word.

He stared at the huge holographic image directly in front of him.

"No, that's not right!"

Looking at the huge crimson fireball in the center of the holographic projection, a flash of light flashed in Lu Yongchang's mind.

"We overlooked one thing!" He suddenly shouted loudly!

"Huh? What?" Fang Xu cast a puzzled look at Lu Yongchang.

"The mass lost by the sun itself during the red giant process!"

There was a bit of excitement in Lu Yongchang's voice, and he suddenly realized that he might be able to grasp the real reason for the sun's mutation!

"According to our previous models, in the process of becoming a white dwarf, the sun will lose about 50% of its mass."

"These ejected substances will exist around in the form of nebulae."

"But now, the sun's variation clearly doesn't fit the model."

NGC 5307 planetary nebula with white dwarf at center

Speaking of this, Lu Yongchang's eyes showed a complex look.

Not only does it not match, it's a world of difference!

Leaving aside the timing of the process of the red giant star, even the extent of the expansion is not right!

In normal prediction models, the red giant star formed by the expansion of the sun will reach the orbit of Mars.

But both the new model and the experience of the previous life tell Lu Yongchang that the red giant star formed by the sun had a helium flash before it even reached the earth's orbit!

The huge difference in the middle means the disappearance of a lot of mass or energy!

"Zero, according to the current state of the sun, how much material will the sun throw out during the entire red giant process?"

Ignoring the suspicious eyes of Fang Xu and everyone else, Lu Yongchang directly opened his mouth and gave orders to Ling.

"Professor, according to the current trend, the sun will eventually eject about 20% of its original mass." Zero quickly answered Lu Yongchang's question.

For it, the problem is not complicated.

Lu Yongchang's face darkened.

really!

A full 30% of the mass disappeared into the universe out of thin air!

Like Lu Yongchang, the faces of all the scientific researchers present also changed drastically.

30% of the mass of the sun, this is an incredible data!

Before the law of conservation of matter is overthrown, there are only two situations that can lead to this phenomenon!

First, the calculation is wrong.

second……
