Xiao Yu quietly observed this small universe for hundreds of years until it was completely stabilized.

Yes, this small universe has now stabilized, its speed of light at this moment no longer changes, but is fixed to the same value as the speed of light in the large universe, the gravitational constant has also been fixed, the four fundamental forces have been determined, and all kinds of constants have been determined, which is the same as the big universe.

Xiao Yu watched like this, watching some of the most basic particles begin to appear in this small universe, and then these baryons, leptons, etc. slowly converge into the most basic atomic nucleus, and the atomic nucleus captures electrons, and finally forms a stable hydrogen element dust.

There are no stars formed in this small universe, so there will be no nuclear fusion reactions, and without nuclear fusion, then there should be no other elements in this small universe except hydrogen. However, this is not the case, when this small universe is just formed, the energy reaction is extremely intense, and at a certain time, under a special rule environment, a small amount of other elements may be formed.

The mass of this small universe is huge, and before the explosion, it had almost ten thousand stars. Now, after the rules have stabilized, these qualities are reappearing. The difference is that now they are in the form of dust clouds. As a result, Xiao Yu observed the scene of the dust cloud slowly condensing under its own gravity. Xiao Yu knew that after many tens of thousands of years, these nebulae would also condense into stars and planets and various celestial bodies, and the stars would reach the end of their lives. There will also be black holes, neutron stars and other celestial bodies. It will be a scaled down version of the three-dimensional universe, except for the difference in volume and mass. There will be no essential difference between this small universe and the three-dimensional large universe.

"In this small universe, when all kinds of different elements are abundant, there may also be complex polymers, and there may also be life and even intelligent life. At that time, these intelligent beings did not know how they would affect this small universe, and they did not know how they would understand the universe in which they lived. Xiao Yu thought silently.

These things are not important, Xiao Yu is still thinking about another question. That is, is there such a process in the three-dimensional universe in which you live? Perhaps, I think it's endless. The infinite three-dimensional universe is also separated from another larger universe?

Xiao Yu has no way to be sure of this. If this is confirmed, then this is another version of the parallel universe theory.

The theory of parallel universes in the absolute sense has been denied by Xiao Yu. However, Xiao Yu has no way to deny this restrictive multiverse theory. The reason is obvious. If the speculated higher-level universe separates itself from the three-dimensional universe in which it lives, then it is equally likely to separate the rest of the three-dimensional universes, and different three-dimensional universes may have different physical rules and developments.

"I can't prove this speculation in a short period of time." Xiao Yu thought silently, "Now what I need to think about is the so-called philosophical weapon, or rule weapon. There is a very obvious situation. It's because I sent a probe to this small universe, and the probe has been operating according to the rules of the three-dimensional universe. Therefore, this probe also brought the rules into this small universe, and finally affected the formation of the rules of this small universe. And if I can influence the formation of the rules of the small universe by some means and let it develop naturally according to my heart, then will it become my most solid rear base and fortress, a source for me to defend against enemies or develop technology? ”

To use the simplest analogy, the building materials that Xiao Yu needs now require an extremely complex purification and refining process to extract. And if Xiao Yu can modify the rules, then Xiao Yu can completely let this material form automatically through natural evolution. This undoubtedly saved Xiao Yu a lot of effort. At the same time, Xiao Yu can also modify the rules of this small universe, only to adapt himself to the environment here, and then if there is an invasion of foreign enemies, as soon as the enemy's spaceship enters this small universe, it will be destroyed because it does not adapt to the rules here, or its combat power will be greatly reduced. In this way, Xiao Yu will undoubtedly have a great advantage.

"In the three-dimensional universe, not to mention the powerhouses such as the Defenders and the Rebel Alliance, there are definitely not a few other seventh- and eighth-level civilizations. Among these civilizations, there must be many civilizations that have found this state of affairs as well. Then, it is almost certain that there will be civilizations that specialize in developing this small universe and formulating their own rules as the direction of development of their own civilization. If you encounter this kind of civilization, then be sure to communicate with them. Xiao Yu thought secretly.

Now, this small universe has completely stabilized, and there is no difference from an ordinary small universe. So there's no point in staying here. During this time, Xiao Yu has gained enough things.

"It's time to get out of here and continue my voyage......" Xiao Yu manipulated his fleet and gradually left here, heading towards the core of the Andromeda Galaxy.

The Andromeda Galaxy is not the same as the Milky Way, it has two cores instead of one. This is a situation worth observing, and in Xiao Yu's speculation, only the collision of river systems can form such a situation. Studying this situation is very beneficial to improve the theory of river system evolution.

Xiao Yu is about 100,000 light-years away from the core of the Andromeda Galaxy at this moment. Based on Xiao Yu's current speed, it only takes about a hundred years for Xiao Yu to get there. Of course, during the voyage, Xiao Yu will also explore the rest of the things he is interested in during the journey. This is an overarching exploration of the Andromeda Galaxy.

The elemental composition of the Andromeda constellation is somewhat different from that of the Milky Way, so there are also some astronomical wonders that cannot be seen in the Milky Way. For example, a star that Xiao Yu saw during his journey.

This star has a full 370 times the mass of the sun, and when Xiao Yu just saw this star, the shock in Xiao Yu's heart was indescribable. It's too big, too big to be true. The greater the mass of a star, the shorter its lifespan, and the total lifetime of a star at this mass level will not exceed a million years. In the long history of the evolution of the universe, a million years is only a fleeting short period of time, and it is not ordinary luck to be able to see this star while it still exists.

Any theory of stellar evolution does not apply to this star, at the beginning of star formation, after nuclear fusion is ignited, the stellar wind will blow away the interstellar dust around it, and it is this mechanism that prevents the possibility of the emergence of massive stars, so it is certain that this large, somewhat extraordinary star is definitely not formed by the condensation of nebulae.

In fact, it was formed by the collision of stars. By chance, two stars will collide and merge to form a new, larger star. There are clear traces of stellar fusion on this star - the composition of different regional elements in this large star is very different. This is obviously due to the fact that after the collision and fusion of stars composed of different elements, their constituent materials have not been completely evenly distributed.

At least such a large star is the product of the fusion of dozens of stars. Stellar collisions are inherently rare, and the probability of dozens of consecutive star collisions in the short lifetime of massive stars is simply negligible. And such a thing that is usually impossible to happen was presented in front of Xiao Yu's eyes under the magical manipulation of the force of nature.

If it weren't for Xiao Yu's impatience, Xiao Yu would be very interested in waiting here for hundreds of thousands of years, waiting for this super-large star to explode, and then observing its explosion. The explosion mechanism of a star of this mass is not the same as that of a normal supernova, it does not leave a neutron star or a black hole after the explosion, it will completely shatter its bones, and all its mass and energy will be ejected into the universe. This supernova explosion was named a photoinduced metamorphosis supernova by Xiao Yu. And it is precisely because the mechanism of the photoinduced transformation supernova explosion is different from that of ordinary supernova explosions, so even Xiao Yu, who has become a seventh-level civilization, has no way to make it explode and disintegrate in advance.

With this regretful mentality, Xiao Yu left here and continued to set off towards the core of the Andromeda Galaxy.

Along the way, Xiao Yu saw a neutron star and an ordinary star forming a binary star system, and the neutron star was devouring the mass of the star and emitting extremely bright X-rays; I saw a white dwarf being captured by a wandering black hole, helplessly revolving around an invisible black hole; I saw that the protostars were condensing, and I saw a three-body system composed of three neutron stars......

Journey all the way, all the way to the wonders. Xiao Yu kept walking through this strange river system, admiring all kinds of different scenery, and after more than a hundred years, Xiao Yu finally came to the core of the Andromeda Galaxy.

Seeing that these two huge black holes that had mastered the entire river system were revolving around each other, Xiao Yu's heart was full of emotion.

These two massive black holes come from two different river systems, and in the distant future, they will also merge together to form a new, larger black hole that will take full control of the entire Andromeda Galaxy. At the moment, they are in the process of rotating around each other. In constant rotation, they are constantly shortening the distance between each other. (To be continued......)
