Voyage of the Stars

A fleet is very complete, not just battleships, but also various types of robots and various functional small spacecrafts in each battleship, and of course aircraft used for internal exploration of the planet.

A sea-class battleship is three kilometers long, and the Tianqin is even five kilometers long. Such a huge volume can fully accommodate supporting facilities with various functions, and even production lines. It can be said that every sea-level spacecraft is a city.

With the deepening of the exploration, the three planetary bases left by the Chiyan Civilization were gradually revealed to mankind. This did not take long. After all, the number of robots invested by mankind was very large.

During this process, human exploration robots received some attacks from the base defense system, and many robots were killed here, but humans did not care because there were many robots.

After more than six months of exploration, humans finally turned the bases on three planets upside down.

Six months is already a short time. After all, the Red Flame Civilization has been operating on these three planets for hundreds of years. Their traces are everywhere in almost every corner of the planet, and their various facilities are everywhere. If humans didn't have a large number of detection robots, they really wouldn't be able to complete the exploration in such a short time.

It is a pity that in the subsequent exploration, except for getting some answers about the functions of various buildings of the Red Flame Civilization, humans have never been able to obtain any useful information from these planetary bases.

Since no useful information can be obtained, there is no need to stay here.

Immediately, Yue Yuan ordered the fleet to return. The First Fleet and the Second Fleet needed a round of supplies and fuel replenishment before they could set sail, so their return destination was the Thirteenth Planet Base.

When leaving, Yue Yuan did not order the destruction of the three planetary bases left by the Red Flame Civilization, not because he was merciful, but because it was unnecessary.

Destroying it is a waste of time.

Next, the First Fleet and the Second Fleet spent a year carrying out material replenishment, fuel replenishment, and maintenance and repair work, and then it was time to leave.

"Commander Yue, the First Fleet, the Second Fleet, and the Third Fleet are ready. The strong artificial intelligence of the four planetary bases has completed the work of gathering the facilities and equipment in their respective areas of responsibility and is ready to set sail at any time."

"Countdown to sailing is 3 minutes, target: JM18756"

After the brief voice sounded, the huge fleet composed of three human fleets finally officially set foot on a new route, or in other words, the route to pursue the Red Flame Civilization.

Like the Red Flame Civilization, humans did not destroy the base they originally built when they left. However, one difference is that humans moved cleaner, except for some temporary buildings, such as some facilities built with reinforced concrete materials. , the others were packed away by humans.

Various human facilities themselves are designed with the concepts of modularity, foldability, and mobility. In other words, the mining bases of human civilization are essentially landing spaceships. They are designed according to the established rules after landing. Programs constitute facilities with different functions.

Just like the combination of "I will form the body, I will form the head, and I will form the arms", humans have been able to easily make these large machines achieve such decent deformations.

Three minutes passed quickly, and the three fleets that were reorganized into a large fleet finally officially embarked on their journey.

More than 12.2 million magnetic thrusters were activated one after another, and each battleship was under unified command, and the propulsion gear was set to the same position. At this moment, a wonderful physical phenomenon that can only be detected by a third-level civilization appeared at the end of the magnetic push. A powerful force appeared at this moment.

There is no bright light, no charming colors, and no passion for the intertwining of light and heat. There is only the invisible phenomenon of the moment of monopole phase transition, and the faint metallic luster that reflects the light of distant stars.

At this moment, the scene of more than 12.2 million human warships setting sail at the same time does not look as shocking as the second-level civilization, but the quality is undoubtedly higher.

It was as if nothing had happened. They accelerated from a relatively stationary state towards the same direction in the starry sky. The advancement of science and technology has made human fleets become more and more sci-fi. Such a fleet, in terms of concealment alone, , enough to defeat any second-level civilization.

In fact, humans are now completely unable to detect the Red Flame Civilization fleet through optical means. One and a half years is enough for the main fleet of the Red Flame Civilization, which left earlier, to disappear from the sight of any low-level civilization.

But that doesn't mean humans can't find them.

Before the big fleet set sail, humans had already sent some advance warships to conduct scattered detection in the direction where the Red Flame Civilization fleet disappeared, just like the scouts sent out during marching operations.

It is through the detection information fed back by these warships that the human fleet plans its route, thereby tracking the Red Flame Civilization Fleet.

For a fleet that uses magnetic thrust technology, the greater the thrust, the more obvious the track, and the longer it will remain detectable. So far, humans have no technology that can erase the traces of these phase changes.

Similarly, the Red Flame Civilization cannot, or even the third-level civilization cannot.

The main fleet of the Red Flame Civilization has more than 70 million spacecraft, and the tracks brought by the huge fleet are very obvious. Even if more than a year has passed, humans can still detect them easily.

The pursuit in the starry sky is actually boring. It is nothing more than batches of detection spacecrafts probing the tracks in front, while the fleet behind them steadily bites the opponent's fleet.

The target star is still twenty light years away. The human fleet needs to accelerate to 50% of the speed of light, and then reduce the speed to the level before setting sail when it reaches the destination. From the perspective of outside observers who are stationary relative to the human fleet, this process takes forty years. But for mankind itself, time only took thirty-five years to reach its destination.

This process can be said to be the dilation of time for a stationary observer in the outside world, or it can be said to be the shortening of the distance traveled by humans. This is the so-called clock slowing effect.

The effect occurs during the acceleration and deceleration of the fleet, rather than during the 50% light speed route. Therefore, the key physical quantity for the clock-slowing and shrinking effect on humans is not speed, but acceleration.

The reason for this is that speed itself is meaningless after losing the reference frame. When the fleet travels at 50% of the speed of light, you can also say that the fleet is stationary.

Because the speed of light does not change, no matter how high your speed is, for light, you are still.

In other words, A moves away from B on the planet at 50% of the speed of light, and conversely, it is also true that B on the planet moves away from A at 50% of the speed of light. But why does A eventually become younger than B after the two speeds are synchronized again? , that’s because the acceleration and deceleration process occurs on A.

This has been verified by humans in the age of the earth, and there is no problem. But know that the reason for all these changes is acceleration.

It is acceleration that changes the properties of space and time.
