Voyage of the Stars

This celestial body simulation system uses the sun as its coordinates, so it is obvious that the rapid changes in the numbers indicate that the planet is moving rapidly relative to the original position of the sun. This is a normal phenomenon, but Callisto is abnormal.

In order to be more intuitive, Gander motioned to the small fish to shrink the overall size so that most of the solar system could be displayed on it.

"We were thrown out!!!" Yue Yuan saw it clearly this time.

"According to the observational data, it is indeed the case." Gander was silent for a while, and said in a calm tone: "As we can see, the super powerful shock wave generated by the solar explosion and the loss of most of the mass due to the explosion cause The gravity decreases, directly changing Jupiter's original orbit.

At the same time, Callisto and the other satellites of Jupiter that had not been destroyed by the shock wave were all blown away by this series of complex effects. Jupiter eventually became a wandering planet because it lost the gravity of the sun. "

"The Callisto we are on was initially protected by Jupiter, but its surface temperature once exceeded 2,500 degrees Celsius. As the space temperature in the solar system skyrocketed, no planet was spared. .”

Gander continued to talk about the answers obtained based on observational data, "Fortunately, our base on Callisto is strong enough and buried deep enough, otherwise we would never have the chance to return to the ground again."

Yue Yuan knew this, so he nodded and interjected: "I heard that the first batch of staff who went up said that when they stepped on the ground, there was still uncooled magma everywhere around the cave entrance. If the engineers hadn't calculated accurately, we would have There will also be a risk of magma intrusion."

"Yes, if only one link goes wrong, we will be in danger." Gan De sighed.

As he spoke, he straightened his aching back, lamented that people's bodies are not as good as before when they get old, and then continued: "Now, the Jupiter we are on has escaped from the gravitational range of Jupiter, and is based on the ecliptic plane of the sun. The angle is 17.3 degrees, heading towards the dark universe.

Not only Callisto, but also several satellites that were not destroyed in the disaster, such as Saturn, Phoebe, and Phoebe, were also thrown out of the solar system. "

Speaking of this, Gander couldn't hide the look of fear on his face: "Actually, we are very lucky. Many satellites fell towards Jupiter during this process, and then were torn to pieces when they crossed Jupiter's Roche limit. , the sky has eyes, we are lucky not to suffer the same fate as them."

Who would have thought that, unknowingly, the surviving humans had escaped another disaster.

It stands to reason that humans on Callisto would be able to detect such a big change in the orbit through instruments, but at that time, in order to save energy, basically all kinds of scientific detection instruments were stopped.

However, according to speculation, when the catastrophe came, the strong shock wave caused great chaos in various solar systems. Under the influence of the chaotic gravitational field, the orbits of various stars underwent a series of complex changes and chain reactions, leading to what they are today. situation.

"Doesn't it mean that Callisto will become a wandering planet, and we will fall into the vast dark universe with Callisto?!" Yue Yuan murmured, this seemed like a question, but Contains too much surprise.

"Yes, with the current relative speed and position of Callisto, it will cross the original orbit of Uranus in three years, and completely fly out of the original solar system in thirty years." Gander gestured on the screen and said,

"In other words, we will get further and further away from the stellar debris until we can no longer get a trace of light. No, it should be said that we are already in darkness now. Because the sun did not become a white dwarf, but was blown into a A nebula. So it's clear that we, like many other planets in the solar system that have not yet disappeared, are still in this cooling nebula of debris."

What a terrible, terrible news!

The sun has been blown into a nebula, and the entire solar system will no longer be the same. There is not enough gravity to bind the planets that have not disappeared, so these planets will slowly go their separate ways.

This means that surviving humans will enter a dark age. In the long future, humans will not be able to obtain a trace of energy from stars, and will fall into a real energy crisis in the not-too-distant future.

It will even gradually wither in the cold universe along with Callisto and perish in an unknown corner of the universe.

This is fatal, and it is also the outcome that Yue Yuan can foresee now.

Because humans do not have the ability to travel to the stars.

Although humans have been able to build such a huge base on Callisto before, the distance from the Earth to Jupiter is not a distance at all in interstellar space, or it is not comparable at all.

Really, the house leaked, it rained all night, the boat was late, and there was a strong wind. Misfortunes never come singly.

"Where is Callisto heading?" Yue Yuan was silent for a moment before speaking, his tone full of expectation.

Gander smiled bitterly. Why didn't he hope that there would be a star system in the direction of Callisto? However, this place in the solar system is already a wilderness of the Milky Way, and the nearest Centauri triple star system was also bombed and was destroyed in the chaos. The probability of a randomly thrown Callisto heading towards the star system is almost zero.

"There is no star system. Judging from the current direction of Callisto, we will pass through the empty space where the Van Manen star, Epsilon indi A, and GJ9066 star systems are located in the future. However, this is only a preliminary analysis, and more accurate data will have to wait. It would take a sweep of ejected material from the Centauri triple star system to determine it."

Because this knowledge is all areas Gander is familiar with, he is basically the one doing the talking.

Perhaps because he had been standing for a long time, Gander, who was a little tired, pulled a chair from the side and sat down, and then continued: "The diffuse debris gas cloud formed by the material ejection of the Centauri triple star system will probably be around thirty years old." We met three years later, but I think the impact will not be big, after all, the distance is already very far.

With our technological strength, if we hide underground on Callisto for a while at most, electronic equipment may be affected. We need to let experts in the related field think of a solution in this regard. "

Yue Yuan understood that Gan De was trying his best to remind himself from the information he had and from his perspective that the disaster was not over yet.

"Well, I will ask experts in various fields to discuss it later. It is always right to prepare for a rainy day." Yue Yuan happily accepted Gan De's advice.

Because he also knew that what Gander said was true. The sun had been blown up to the point that it was no longer qualified to become a white dwarf star. Presumably the Centauri triple star system would be no exception.

"The good news is that after Callisto is heated, we don't need to worry about energy issues in the next few decades." Gander said again.

Before Yue Yuan could be happy, he opened his mouth to break the bad news: "But because of this, we may have to worry about other resources."

"This shouldn't be a big problem." Thinking it was a problem, Yue Yuan breathed a sigh of relief.

"Oh?" Gan De did not expect that Yue Yuan actually said that the problem he was worried about was not a big problem.

"We have Callisto." Yue Yuan smiled.
