Of course, Xiao Yu did not actually observe a gamma ray burst in the Andromeda Galaxy five million years ago. When he was in the Andromeda Galaxy, Xiao Yu once reached the remains of the neutron star collision. Two neutron stars collided.
A black hole was formed, and around the black hole there was some material thrown out during the collision, forming an accretion disk orbiting the black hole. Through the analysis of these relics, Xiao Yu determined
What happened here millions of years ago, and it was determined that a gamma ray burst occurred here, and the intensity of that gamma ray burst was also measured.
This is something that should only exist in inference, and it should not be measured by Xiao Yu in reality. But now, Xiao Yu has actually observed this gamma ray burst, and all the data of this burst, and
The explosion that Xiao Yu deduced was exactly the same. Such a coincidence is basically impossible.
Xiao Yu once again fell into an inexplicable shock. So Xiao Yu immediately launched a follow-up observation of the Andromeda Galaxy. For this extragalactic galaxy closest to his hometown, Xiao Yu has never had the ability to sail into the universe since he had the ability to travel far into the universe.
Xiao Yu has relaxed his observation of it. In the past more than 100,000 years, Xiao Yu has accumulated a large amount of information about the Andromeda Galaxy. At this moment, the light carrying this gamma ray burst has been observed by Xiao Yu
When it arrives, it means that the light carrying the rest of the change information has also arrived in the Milky Way.
After observing the Andromeda Galaxy for a month, Xiao Yu was completely certain of this incident. He confirmed the authenticity of the time-reversal event that also occurred in the Andromeda Galaxy.
"What does this mean? Why did the Milky Way change when I left the Milky Way? I left the Andromeda Galaxy. The Andromeda Galaxy also changed?" Xiao Yu thought silently, "Among these things,
There seems to be some pattern. This change seems to be following my footsteps.”
"Then, according to common sense, the Large Magellanic Cloud, the Small Magellanic Cloud, and the Ursa Major Dwarf Galaxy should also have changed. After all, I have been to those places."
So Xiao Yu immediately shifted the focus of his observations and aimed a large number of high-precision long-distance observation equipment at these three dim Milky Way satellite galaxies in the celestial sphere. However, the data obtained from the observations once again exceeded Xiao Yu's expectations.
Among the three satellite galaxies of the Milky Way, the Small Magellanic Cloud and the Ursa Major Dwarf Galaxy have not changed. On the contrary, the Large Magellanic Cloud has undergone some changes. Xiao Yu observed that the size of the Large Magellanic Cloud has decreased a lot, and its mass has also decreased.
Reduced by at least 60%.
"It's understandable that the Small Magellanic Cloud and the Ursa Major Dwarf Galaxy have not changed. It's just that the change has not spread to them. Or they have not changed at all. What is the explanation for the Large Magellanic Cloud?" Xiao Yu was thinking at this moment.
It's full of fog.
After thinking for a moment, Xiao Yu made a decision. Dozens of voyage fleets were sent out by Xiao Yu, heading towards dozens of satellite galaxies in the Milky Way. Xiao Yu decided to search for the Pegasus civilization in these satellite galaxies.
Traces. During the period of his absence, the Pegasus civilization is unlikely to make a technological leap, which means that it is very likely that they are still in the sixth-level civilization stage. As long as they are in the sixth-level civilization stage, then
Basically, they do not have the ability to sail across the galaxy, but can only transfer between the Milky Way and the satellite galaxies of the Milky Way. While these voyage fleets are looking for the Pegasus civilization, they are also tasked with exploring those satellite galaxies.
Xiao Yu's huge tentacles have been fully extended. He is searching for all information that can help solve the current predicament.
The fleet heading to the satellite galaxy of the Milky Way has not yet reached its destination, and the exploration fleets within the Milky Way have already reached their targets. The main targets of this round of exploration are the various advanced civilization relics hidden inside the Milky Way known to Xiao Yu.
The first thing Xiao Yu detected was the relics of the mechanical seventh-level civilization around the galactic center. The relics of this mechanical seventh-level civilization were cleverly hidden using space technology, but now Xiao Yu is also a seventh-level civilization.
A super civilization naturally has the ability to find it.
Xiao Yu measured the space curvature and fluctuations in various areas around the galactic center in detail. After more than ten years of exploration, the final result was nothing. According to the information from the last time he came to the galactic center, Xiao Yu was sure
, if the ruins of the seventh-level civilization are still here, then with such an intense search, I can definitely find it. But the current result is nothing, which is worth pondering.
"Is it gone? The true sense of turning back time in the galaxy should not be like this. If it is a true sense of going back in time, then the scene in the galaxy should not change so much, at least for the two sweepers and guardians.
Civilization should exist, and this ruin here should not disappear." Xiao Yu thought slowly. At this time, another exploration fleet had arrived in the Eagle Nebula.
The Eagle Nebula is an important stop on Xiao Yu's galactic journey. It was in the Eagle Nebula that Xiao Yu encountered the white dwarf alien beast called the Mirage, and obtained the body of his compatriot, the earth girl Zhang Shengya, and
According to the diary prompts left by Zhang Shengya, he found a way to unify the four basic forces in the multi-body system, finally mastered curvature navigation, and became qualified to truly enter the vast universe.
Xiao Yu quickly found the star he named Aquila A, and then extended it further to find the binary star system where the mirage once lived.
The white dwarf alien beast once said that it was injured by the Taihao civilization and trapped here for nearly tens of millions of years. According to common sense, if the time of the Milky Way goes back 2.5 million years, this alien beast should still be there at this moment.
It's better to stay on top of that white dwarf. But when Xiao Yu's fleet arrived here, they didn't find any clues on this white dwarf. This white dwarf, like other white dwarfs in the Milky Way, is orbiting its companion star.
The common center of mass of the two stars moves quietly without any abnormalities.
It is just an ordinary white dwarf star. Apart from having a companion star, there is nothing special about it. Xiao Yu did not find a powerful beast on it that has become a level six.
Xiao Yu felt disappointed in his heart. Xiao Yu had already anticipated the situation he would encounter next, but Xiao Yu still set off.
The destination of this departure is a more ordinary star system ahead. It is the home of the Yaju. According to Xiao Yu’s understanding of the history and evolution of the Yaju clan, Xiao Yu knows that, according to common sense, at this moment
The Yaju clan should still be at the level of second-level alien beasts, and the entire clan only has about 10,000 animals.
Xiao Yu found a planet with an ecological environment very similar to that of the Earth. There were a large number of animals and plants on this planet, and the ecological environment was good, but Xiao Yu found no trace of the beasts.
Mountains, rivers, oceans, lakes, forests and deserts, the terrain on this planet is diverse. There are birds, animals, carnivores, and herbivores. Tens of millions of species live on this planet.
They reproduce quietly. They have long formed a stable food chain and are closely integrated with the planet's environment. Everything is natural.
The scenery here is beautiful, at least from Xiao Yu's perspective. But the robot that represents Xiao Yu's will felt a biting chill while standing in this picturesque scenery.
There is something missing here. Without the Yabushi race that already possesses wisdom, Xiao Yu always feels that something is missing here.
Xiao Yu also found nothing here. At the same time, another fleet arrived at the ruins of the seventh-level silicon-based civilization that Xiao Yu had visited. But unfortunately, it was also empty there, with only a white dwarf star and a
A binary star system composed of ordinary stars. There is also a planet rotating around them in this binary star system. Xiao Yu explored this planet. As expected, the dilapidated and huge suspected seventh-level civilization on this planet
The factory buildings have also disappeared. It is completely an ordinary planet without life. On it, there are only gentle plains and mountains, and occasionally there is a canyon. Because the core activity of the earth has stopped long ago, it
There are no mountain-building movements, volcanoes or earthquakes on it. Only the dense craters dotting it tell the story of the experience of outsiders coming here.
The broken seven-level silicon-based civilization neutron battle star naturally disappeared. It seemed as if such a thing had never existed here.
Xiao Yu also went to the ruins of another seventh-level civilization, the star gate left by the seventh-level or eighth-level civilization in the direction of travel. It was with this star gate that Xiao Yu was able to cross hundreds of years in just a few years.
The distance is ten thousand light years, but what is presented to Xiao Yu at this moment is nothingness.
I don’t know where the star gate went.
Xiao Yu frantically explored the galaxy. Xiao Yu did not let go of any place he could set foot in, but he still found nothing. Everything here was so similar and yet so different from what Xiao Yu remembered. It was like the entire galaxy.
Although time went back, some things were lost in the process, and these things happened to be crucial to Xiao Yu.
Xiao Yu even couldn't help but have some doubts about his memory: "Did I really walk out of the Milky Way? There is nothing in the Milky Way at this moment that can prove my existence..." (To be continued
