Super Battleship Reborn

Chapter 33 Unusual Signals Since the first time Homo sapiens looked up at the starry sky millions of years ago on the earth, human beings have never stopped exploring the mysterious universe.

Until today, Xiao Yu has taken a crucial step.

Humans finally moved a whole light-year distance.

Although, in the universe, only Xiao Yu is left as a human being.

Here, is the Oort Cloud. Here, it is one light-year away from the sun, about 9.5 trillion kilometers away. Looking at the sun here, it is better to see Sirius bright on the earth. The sun has truly become an ordinary member of countless stars.

In the distance, a dark meteorite block of about ten cubic meters flashed past and quickly ran towards the sun.

Xiao Yu smiled bitterly. Because he observed, because of the influence of the quality of his fleet, the orbit of this meteorite has been changed. According to calculations, after thousands of years, it will enter the inner solar system, and after emitting a spectacular tail, it will be evaporated by the sun.

Here, there are hundreds of billions of meteorites scattered in the vast darkness, and their total mass is estimated to be about ten times the mass of the earth. They are the remnants of the sun. Due to the influence of Jupiter and other large planets, they were not fortunately aggregated into a large planet like Earth or Mars, but were driven out of the interior in the gravitational war billions of years ago. The solar system has come to this lonely place. Only a few meteorites can get the chance to meet the sun again.

It's too far from the sun. Being as far away as the rest of the stars may also have an effect on them. It is expected that in millions of years, a star called Gliese 710 will pass them at close range. At that time, part of the Oort Cloud will be captured by it, and another part of the star may be captured by it. banished to the inner solar system.

Xiao Yu commanded a village-level spacecraft, flexibly approached a meteorite block with a volume of about tens of cubic meters, and captured it inside the hull. These meteorites contain some traces of the early formation of the solar system, which is very helpful for Xiao Yu to study the evolution of stars.

Except for the two meteorites Xiao Yu observed, the Oort Cloud is still as empty as the rest. Xiao Yu's footsteps did not stop at all, and continued to pass through at high speed.

The Oort Cloud is the final boundary of a star's sphere of influence. Beyond the Oort Cloud, there will no longer be any stars controlled by the Sun's gravity. Except for a faint starlight, the sun will not be able to make any influence here.

Perhaps, five billion years later, when the sun died, the planetary nebula she formed might spread here.

Countless times have passed in a hurry, and more than two thousand years have passed since Xiao Yu left the Oort Cloud.

When 1,600 years passed, all the replacement parts that Xiao Yu had in reserve were used up, so in the next 400 years, fifty village-level spaceships were abandoned. The parts on them were removed and installed on the rest of the ships, replacing their damaged parts. These fifty village-level spaceships only have an empty shell left. Without their power systems, they will not have the ability to continue to follow the large army, and Xiao Yu will not have the ability to carry them additionally. Abandoned, they can only drift along a fixed track in the endless universe, forever.

Along with the fifty village-class spaceships, there were also two township-class spaceships. Although the three county-level spaceships have also undergone an overhaul, they still have the ability to continue sailing.

Forty percent of the entire voyage has been covered, a distance of four light-years. If Xiao Yu's goal is the chosen Alpha Centauri star, Xiao Yu has now reached his destination.

Alpha Centauri, commonly known as Proxima Centauri, is a triple star with three stars orbiting each other in a chaotic motion. According to observations, there will not be any stable large planets there,

So although it was the closest there, Xiao Yu didn't choose it.

In these two thousand years, Xiao Yu has passed through at least four large gas clusters. Every time he passes through a gas cluster, Xiao Yu's speed is reduced once, and then Xiao Yu has to accelerate and correct his course.

And every acceleration and course correction consumes a lot of fuel. However, thanks to Xiao Yu's reserves as much as possible at the beginning, the nuclear fusion fuel reserves are still optimistic, enough to support Xiao Yu's voyage to the Tianyuan four-star system.

The largest of these gas masses is a light-year long and a dozen light-days wide. It took Xiao Yu more than 20 years to pass through it.

There are quite a few such large gas clusters in the universe. Even the solar system was born from such a gas mass. That was billions of years ago, when the gas mass began to slowly shrink toward the center, disturbed by a nearby supernova explosion. In the end, in the center of the gas mass, the density of matter became higher and higher, and the temperature became higher and higher, which finally triggered the nuclear fusion reaction, and the original sun was born.

The powerful stellar wind of the original sun blew away the dust that surrounded itself, and then the dust slowly condensed into planets one by one. After billions of years of development, it stabilized and became what it is today.

If at this time, a star exerts a certain influence on this gas mass, in the endless future, a star may also be born here.

It's a pity that Xiao Yu doesn't have such ability, otherwise Xiao Yu would be very interested in creating a star.

This gas mass completely reduced Xiao Yu's speed from 563 kilometers per second to 506 kilometers per second, and shifted Xiao Yu's course by one thousandth of a degree.

Interstellar navigation must be absolutely precise, and its accuracy requirements are even more precise than hitting mosquitoes on the moon on the earth. Because the distance is too long, the initial small error will be magnified countless times. If you let this one-thousandth of a degree error, Xiao Yu will pass tens of billions of kilometers away from the destination.

Fortunately, Xiao Yu has a pulsar navigation system. With the help of the signals of the six pulsars, the course was re-corrected, and Xiao Yu continued to gallop towards Tianyuan Si.

Here, it is five light-years away from the sun and four or five.5 light-years away from Tianyuan. The voyage is about to finish halfway, and it has been 3,700 years since Xiao Yu set off from Saturn.

The loss of village-level spaceships increased to one hundred and thirty-five, and the loss of township-class spaceships reached eight. However, the three county-level spaceships are still the same, and everything is running normally. The reason is very simple. The county-level spacecraft has the greatest value. Usually, Xiao Yu removes the parts from the village-level and township-level spacecraft and installs them on the county-level spacecraft. By sacrificing the small spaceship, the health of the big spaceship was exchanged.

Xiao Yu's fleet is like a group of refugees who have fled. Along the way, refugees continue to die of cold and starvation, and then they are ruthlessly abandoned.

Although nuclear fusion is the most efficient energy source at this stage, the materials used to build the spacecraft are the embodiment of Xiao Yu's highest material technology, but they are still somewhat powerless in the face of a long time. Before Xiao Yu's technology made new breakthroughs, these losses were inevitable.

Here, five light-years away from the sun, the brightness of the sun further weakened, and it finally disappeared from the stars, and could no longer find any features. The luminosity of Tianyuan No. 4 keeps getting brighter. Even without the shielding of a few gas clusters, Tianyuan Si is brighter than the sun when viewed here.

During these nearly 4,000 years, Xiao Yu's technology has been developing, but only at the technical level. For example, Xiao Yu has an updated photonic computer construction model. It is expected that after the model is perfected, Xiao Yu will be able to create more Today's photonic computers are dozens of times faster, but have much smaller energy consumption and volume than new computers, such as more efficient nuclear fusion application technology, and the internal mechanism of wood spirit reinforcement materials. Now Xiao Yu can use some kind of strong magnetic field to simulate the process of wood spirit strengthening materials, but the efficiency is not as high as that of wood spirit.

Another most significant breakthrough is about laser application technology. Laser application technology can be divided into two aspects. The attack aspect is traditional laser guns, laser cannons, etc. The defense aspect is the legendary shield technology. Now Xiao Yu has a preliminary inference about the technology of the energy shield, which is nothing more than using a strong magnetic field to constrain high-energy photons to form a protective film outside the hull of the spacecraft. It's just a specific verification, and it still needs to wait until the Tianyuan four galaxies have obtained sufficient material supplements before it can be carried out.

In contrast, there is still no breakthrough development at the fundamental physics level. However, Xiao Yu was not in a hurry. Xiao Yu believes that it is only a matter of time before the breakthrough of basic physical theory will occur after reaching the Tianyuan 4 galaxies and obtaining enough material supplements to build a large particle collider around Tianyuan 4.

Xiao Yu even had a vague speculation in his heart that if the four large particle colliders in Huantianyuan really found the Higgs boson, thus verifying the Higgs field, Xiao Yu would have the hope of obtaining a near-infinite particle collider. The source of energy, at that time, all the difficulties that hinder Xiao Yu's voyage will be annihilated by ash.

From here, we can also see the greatness of relativity and quantum theory. Even now, with the ability of interstellar navigation, Xiao Yu, who is many years more advanced than human technology, in the final analysis, is still living on the basis of relativity and quantum theory.

The endless voyage continues. The village-level spaceship that was playing the vanguard suddenly detected an unusual fluctuation.

It was a burst of radio waves with a certain pattern. Xiao Yu could confirm that the radio wave was not sent out by himself.

This radio wave immediately attracted Xiao Yu's full attention. But because the duration of this radio wave was too short, Xiao Yu had no way to locate its source. After thinking for a while, Xiao Yu made a decision.
