There is little chance of a breakthrough in computational science in the short term, but the construction of Cluster-class warships is within the predictable timeframe. In the previous construction tasks, when building those planetary-class and stellar-class battleships, Xiao Yu had already accumulated enough industrial base, so building Star Cluster-class battleships was a matter of further development, rather than something from scratch.

This saved Xiao Yu a lot of time. But even so, Xiao Yu estimated that it would take five hundred years to build the first Cluster-class battleship he owned.

Time slipped away quietly in such a busy, Xiao Yu was developing his own technology, focusing on space technology and computing technology, while searching for the disappearing small universe, and at the same time building a Cluster-class battleship.

In the quiet starry sky, countless stars are slowly moving according to their own orbits, and everything is in order. Even the most chaotic places are still sophisticated, like meteorites flying in the asteroid belt, where the seemingly chaotic places are still governed by the laws of physics that are extremely precise in the behavior of these substances. This is true of the black hole in the middle of a river system, which is 100 million times the mass of the sun, and the smallest speck of dust at the edge of the galaxy. It's as if there is an invisible hand in this vast universe, manipulating everything in the universe. Xiao Yu knew that the name of this big hand was the law of physics.

Xiao Yu sometimes takes out a little computing power and energy, and while carrying out various complicated work, he quietly looks at the vast and deep universe, thinking about nothing, just staring blankly. Feel the mysterious power that exists behind this universe.

In Xiao Yu's words, any phenomenon in the universe, any behavior of any matter, can be explained. A meteorite suddenly changed its trajectory and rushed towards another meteorite. This phenomenon cannot be without roots, and it cannot change its course for no reason. The fact that it has changed its orbit only means that another force is attached to it. A meteorite changes its orbit, a star explodes, planets condense, collide, and nuclear fusion. Wait, all the terms and behaviors that Xiao Yu can come up with can be explained by the laws of physics.

"So. Are there any phenomena in this universe that do not need to be explained? For example, if a planet explodes, it has no cause, no basis. It is not governed by any laws of physics. It exploded like this for no reason, could there be such a situation in this universe? If such a place exists, it must not be in this universe in which I live. In that place, there must be a lot of unexplained mysteries...... If there is such a place, then this place must be beautiful and wonderful. Xiao Yu muttered to himself.

At the same time, Xiao Yu also extended a little idea of the so-called philosophical weapon, or the weapon of the law of cause and effect.

There must be an effect, and there must be a cause. This is something that is determined by the laws of physics in this three-dimensional universe. It's like a meteorite changes its orbit and hits another meteorite, which is the effect, and the cause is that another force acts on it. The law of cause and effect, or philosophical weapon, that Xiao Yu had previously conceived, was based on this principle, first assigning the effect, first letting this meteorite hit another meteorite, and then assigning the cause by the natural forces of the universe and the laws of physics. Cause and effect is the basis for the existence of this universe, the basis for the existence of all physical laws, and the universe has some kind of self-healing ability, which is something that Xiao Yu has determined, so it is very likely that the universe also has self-healing ability in terms of the law of cause and effect.

At the end of the day, the universe does not tolerate anything that violates the law of cause and effect. It doesn't allow the unexplainable, such as a planet exploding for no reason. And if the result cannot be changed, then the universe has to create its own cause for such events in order to maintain the normal operation of the law of cause and effect. This is the principle of causality weapons.

Xiao Yu's previous assumption was the same. But Xiao Yu has now discovered a new possibility for the existence of a causality weapon. In this mechanism, the law of cause and effect does not exist or is temporarily shielded, and in this mechanism, something can happen for no reason without any reason. When a planet explodes, it just explodes for no reason, and if you ask the reason, ask why it explodes, unfortunately, there is no reason, there is no reason. There is no cause and effect, no laws of physics to support this phenomenon, but it just exploded.

This is the second possibility of existence of the weapon of the law of causality.

Of course, these things that Xiao Yu is thinking about now have no practical meaning for Xiao Yu at this stage. However, the development of science stems from this kind of wild thinking in a large sense, and in the future, maybe Xiao Yu can really create a weapon of the law of cause and effect according to this principle, which is a bad thing.

In such a quiet situation, time passed little by little. The manufacture of the Cluster-class battleship had been completed for the most part, and at this time, Xiao Yu had made some other discoveries.

Xiao Yu finally noticed a trace of the existence of a small universe. After disappearing for hundreds of years for unknown reasons, Xiao Yu finally found the trace of this small universe again. At Xiao Yu's location, through spatial fluctuations and gravitational detection, Xiao Yu once again determined the location of this small universe.

"What has happened within you in the course of hundreds of years? Where did you go during this period of vanishing? Xiao Yu thought secretly, "Let's launch a probe into you first." ”

Xiao Yu did detect traces of the existence of this small universe, but the data parameters were a little different from before. Specifically, the gravitational force and spatial fluctuations detected by Xiao Yu are very weak, unexpectedly weak. This seems to indicate that this small universe has only a very low mass. This is not the same as the previous probe. Xiao Yu clearly remembered that when he entered that small universe before, there were nearly 10,000 stars in the small universe.

Xiao Yu wasn't sure if this small universe was not the one he had entered before. But even if it wasn't, it was suspicious enough for a small universe to suddenly appear here, and Xiao Yu still decided to probe it. If it is still the original small universe, then by exploring the changes that have taken place in this small universe during this time, it may be possible to give Xiao Yu some new gains.

A special probe was launched by Xiao Yu, but an accident happened, and the Luoya round cup technology based on the five-dimensional space could not complete the connection between the large universe and the small universe. This is a situation that Xiao Yu did not expect, and similarly, Xiao Yu still can't make a reasonable explanation for this phenomenon.

Then there are only two options left, one is to build a space bridge into this small universe, and the other is to cut the space, create a small universe again, and then put the detection equipment into this small universe, and then promote the fusion of this new small universe and the original small universe, and send the detection equipment to this small universe in this way.

Among the two options, Xiao Yu chose the latter. Because Xiao Yu was worried that if he directly connected the small universe with the big universe by building a space bridge, it might destroy the original environment in some small universes.

As a result, this detector was put into a new, extremely small universe by Xiao Yu. In order to maintain the stability of the entropy of this small universe, Xiao Yu also had to provide energy for this small universe uninterruptedly. After everything was ready, this small universe, driven by the initial momentum, began to move closer to the original small universe. Through gravitational and spatial fluctuation detection technology, Xiao Yu can grasp the state of the two small universes in real time and accurately.

After drifting in the four-dimensional void space for a while, this small universe carrying the detection instrument finally reached the side of the original small universe. According to Xiao Yu's calculations, based on gravity and the power of space fusion, this small universe should easily attach to the original small universe and begin to merge. But the accident happened again, and the force of the calculation that drove the fusion did not appear. However, because the initial calculation was very accurate, the subsequent launch of the small universe was still attached to that small universe. The fusion of the small universe has finally happened, but at a much slower pace than expected.

And with the process of cosmic integration, Xiao Yu discovered more unexplainable phenomena. Specifically, the signs of the previous small universe were very weak, and Xiao Yu could only detect them with extremely high accuracy, and with the beginning of the cosmic fusion, this sign of the existence of the small universe was rapidly expanding, and it was rapidly moving towards a normal level.

The cosmic fusion has not yet been completed, and Xiao Yu has no way to observe this small universe, so Xiao Yu does not know what happened in this process, and there is no way to explain these strange situations.

Xiao Yu became more and more curious, and looked forward to the detection results of the probe.

Finally, after a few years, the fusion of the two small universes was finally completed, and the probe built by Xiao Yu finally successfully entered this small universe that was detonated by Xiao Yu and then restored again.

What is presented in front of Xiao Yu is a magical world. After receiving the detection data of the detector and seeing this small universe for the first time, Xiao Yu couldn't help but stay there. (To be continued......)
