At this moment, the closest star to Xiao Yu is the C star. Its color is yellowish-white, which indicates that its surface temperature is higher than that of the sun, and correspondingly, its mass is also greater than that of the sun, about 1.8 times that of the sun.

Depending on the surface temperature, the star will appear in different colors, from low to high, red, yellow, white, and blue. Generally speaking, the higher the surface temperature of a star, the more massive it is, but it is not absolute. For example, the red giant star is also red in color, but it can be many times larger than a red dwarf. It has a red color because it reaches the end of its life, when it grows in size and its temperature decreases.

Star C is a yellow-white star that is the largest of the four Aquila galaxies. Right now, the poor planet is orbiting it. Xiao Yu's destination also points to this star.

Generally speaking, the orbits of planets orbiting stars are predictable, for example, the Earth, at a certain time of the year, the distance from the Sun is fixed, even if there is an error, it can be ignored, which leads to the Earth's orbit is also stable. But this planet is not. At a certain point in time when the star is orbiting, there are often big changes from the previous week to the current week. This means that its orbit is extremely unstable. It doesn't look like a stable planet, but rather like some comet in the solar system that has arrived from interstellar space.

It is clear that this instability is due to gravitational perturbations from the rest of the stars. Moreover, this perturbation is extremely strong, causing it to frequently change host stars.

Before arriving at Aquila 41 years, Xiao Yu had already carried out observations of this planet. Over the course of the year, it changed its host star six times, on average, every two months. The degree of instability of its orbit can be seen.

After approaching this quintary star system. Xiao Yu really felt its magic.

Since there is no diffuse reflection in the universe, the cosmic matter, whether it is a planet or a spaceship, when it is close to the star, is day on the side facing the star, and night on the side facing away from the star. But there is no such thing as night in this galaxy. Xiao Yu's fleet, whether it was front or back, front or back, was all illuminated by the stars.

Xiao Yu observes the data of these stars. While carrying out their own journey. At this moment, the distance from that planet is only 300 million kilometers.

Xiao Yu has fully penetrated into the interior of this star system.

At this distance, Xiao Yu suddenly observed that the five stars twinkled at the same time. At this moment, the position of these five stars. At the same time, it is offset by about 0.3 degrees. But the next moment, they were back to normal. It's like this change. Never happened in general.

This phenomenon aroused Xiao Yu's vigilance.

"What's going on? Will they still be able to teleport? Xiao Yu thought suspiciously. I retrieved all the observation data at that moment and analyzed it carefully.

But the results of the analysis made Xiao Yu even more puzzled. Because Xiao Yu saw that at that moment, the mass of all the stars, the luminosity. All parameters, such as tracks, are normal. This made Xiao Yu begin to wonder if there was something wrong with his observation instrument.

But Xiao Yu quickly ruled out this conclusion. If a single instrument fails, it's okay to say that thousands of instruments fail at the same time? The odds are too small. Negligible.

Xiao Yu was faintly excited.

"I can't explain this phenomenon yet. In the girl's diary, it was said that within this five-star system, there is a mystery about the theory of great unification, could this strange phenomenon be related to the theory of great unification? ”

This is the most plausible explanation.

"At the moment, I don't know anything about how this phenomenon came about or how it works, but as long as I stay here for a long time, I can always find a way to figure out everything about it. As long as this phenomenon is clearly explained, I believe that it will not be far from me mastering the theory of great unification. ”

Xiao Yu was even more energetic. The unknown is not scary, and the scary cannot discover the unknown, and think that he is in control of everything. For example, in Newton's time, the people who summarized the three laws of mechanics and discovered Uranus and Neptune with the help of this tool even thought that they had mastered the operation of the entire universe. Correspondingly, scientific theories began to stagnate in this era, until the genius scientists represented by Einstein discovered new unknown phenomena, and through the study of these unknown phenomena, they put forward new theories again, which promoted the accelerated progress of human society and entered the atomic age.

Quantum mechanics and the theory of relativity both emerged in this great era, which strongly and powerfully promoted the development of mankind and drove people to study more unknowns and obtain more knowledge.

Xiao Yu's spaceship gradually approached the planet and entered the orbit that orbited it. At close range, Xiao Yu clearly saw the surface of the planet.

It was smooth ground that took on the shape of black crystals, and there was basically no big undulation, no mountains, no valleys.

"It's really pathetic." Xiao Yu muttered to himself, and in his heart, his sympathy for this planet rose another point.

The condition of its surface is a clear indication of how it has suffered. The black surface is all rocks that have melted in the past. It is conceivable that in the past, it has been close to the star countless times, and then it has been burned by the star's massive heat, causing the rock surface to melt away, and then when it is far away from the star, it has cooled and condensed again, and it continues to melt until the next time it is close to the star......

In this repeated process of condensation, melting, condensation, and melting, all geological details of its surface are erased.

It doesn't have an atmosphere, and in fact, even if it had an atmosphere when it was first formed, it was already stripped away by the stars in the midst of this endless torment. Just like now, it is only about 50 million miles away from star C, less than half the distance between the Earth and the Sun. In addition, the stellar activity of star C is also much higher than that of the Sun, and at such a distance, if the Earth were here, the Earth's atmosphere would be completely stripped away in a million years.

Under the light of star C, its surface temperature reached about 400 degrees Celsius, and at this temperature, its rocky surface began to glow a faint red light, like a terrifying lava hell.

In addition to the C star, the D and E stars are not too far away from it, at a distance of 170 million and 200 million kilometers, respectively. On this planet, star C is the size of a millstone and is dozens of times brighter than the sun, star D is the size of a basketball and slightly fainter than the sun, and star E is the size of a football and is a faint red color, a dozen times brighter than the sun, but still a thousand times brighter than the full moon.

There are three stars in total, shining on this hellish shijie.

On the back of it, the view is even more fantastic. Since it is now gravitationally locked by the C-star, it always faces the C-star with one side. On its back, there are stars A and B at a distance of 770 million kilometers and 800 million kilometers from it. At this distance, the two stars each emit a dozen to a hundred times the brightness of the full moon, reflecting its surface in a dusk that is roughly equivalent to the twilight above the earth, and if someone were to read a book here, he would not need to rely on the rest of the light sources to read the words on the book.

The temperature on its back is about 10 degrees.

The place where Xiao Yu wants to stay is probably like this.

"The environment is not very good, so I can barely do it." Xiao Yu smiled bitterly in his heart.

This place, compared to the Aquila three-star system and the mother star of the beast, is nothing less than a world of difference.

In such an environment, Xiao Yu began his own preparations.

First of all, the Large Particle Collider is a must. Here, though, it's not appropriate to orbit the star. So Xiao Yu chose to downsize it and let it orbit the planet. Secondly, in addition to studying various unknown phenomena here, Xiao Yu also plans to upgrade the fleet, so a large dock is also a must.

There are no gas planets here, so the source of fuel is an issue. In order to solve this problem, Xiao Yu had to carry out mineral exploration on this planet, intending to replace nuclear fusion energy with nuclear fission energy.

In Xiao Yu's planning, nuclear fusion fuel is an emergency material and cannot be used lightly. The energy sources in the Aquila four star system will be dominated by solar energy and fission energy.

At the same time, in order to obtain enough building materials, Xiao Yu also needs to build a base on this planet. In order to combat the heat of the stars, these bases need to be built underground, which undoubtedly increases the amount of work. But Xiao Yu was not in a hurry. Overcoming the theoretical barrier of great unification is a long-term process, and Xiao Yu does not expect to make a breakthrough in a short period of time.

After launching many satellites for geological exploration and gaining a detailed understanding of the planet, Xiao Yu transported many modified robots to the surface of the planet and began the construction of the base.

In the midst of all the busyness, Xiao Yu still did not leave behind the observation of the five stars.

Three days after coming to this star, Xiao Yu observed this strange instantaneous shift of the star again. Unlike the last time, this time the phenomenon happened on the dark side of the planet.

Two huge and bright moons, in Xiao Yu's field of vision, suddenly disappeared and appeared in another position, offset by about 0.6 degrees. It lasted about three thousandths of a second, and then returned to its original position, still hanging faintly in the air, as if nothing had happened.

"Is it finally happening again?" Xiao Yu's heart became excited. (To be continued......)
