When I traveled through time and became a chief, I ruined the system.

The land was empty in the cold dawn. There are no pyramids, no United Nations building, and the huge monuments are missing. Only the dark Gobi Desert stretches to the sky.

But Luo Xiaofei soon discovered that this was just his illusion. The densely packed small rocks on the Gobi Desert were actually human heads! It turned out that the ground was full of people.

Luo Xiaofei stood on a slightly higher hill and looked down. This dense sea of ​​​​people stretched as far as the eye could see. Luo Xiaofei roughly estimated the number. There may be hundreds of millions of people in the range of sight! He knew that everyone in Sanyang World might be gathered here. Silence enveloped everything, and the silence created by these hundreds of millions of people had a suffocating weirdness. This sea of ​​​​people at dawn was waiting for something.

Luo Xiaofei looked around and found that everyone was looking up at the sky. Luo Xiaofei looked up and found that the starry sky had undergone incredible changes:

The stars actually formed a neat square array!

But Luo Xiaofei soon discovered that this square of stars might just be in a planetary synchronous orbit, with the Milky Way's star sea becoming a dim background behind it, and the square obviously moved relative to the background.

In the square array, the stars on the side facing the morning light are the brightest. The silver light emitted can cast shadows on the ground, and the brightness gradually decreases toward the back. Luo Xiaofei counted and found that there were more than thirty stars on one side of the array, so the total number of stars in the array was about a thousand. This array of obviously man-made objects moves slowly as a whole on the background of stars, looking full of solemn power.

At this time, a man standing next to him gently pushed him and whispered: "Ah, great King of Light, why did you come so late? Three rounds of civilization have passed. What a great cause you have missed. !”

"What is that?" Luo Xiaofei asked, pointing to the array of stars in space.

"That's the great Sanyang Star Fleet, and it's about to set sail for an expedition."

"So, the Sanyang civilization already has the capability of interstellar voyages?"

"Yes, those magnificent spaceships can reach one-tenth the speed of light."

"Achieving one-tenth the speed of light, at least within the scope of my knowledge, is a great achievement, but it's still a bit slow for interstellar travel."

"A journey of a thousand miles begins with a single step," the man said. "The key is to find the right goal."

"Where is the fleet's destination?"

"A star with a planet four light-years away. It is the closest star to the three-sun world."

Luo Xiaofei was a little surprised, "The nearest star to us is also four light years away."

"you?"

"Earth."

"Oh, there is nothing surprising about this. In large areas of the Milky Way, the density of stars is very uniform. This is the result of the long-term adjustment of the gravitational force of the stars. A considerable proportion of stars are separated by three to six light years. between."

At this time, huge cheers broke out from the crowd.

Luo Xiaofei looked up and saw that the brightness of each star in the square star array in space was increasing sharply. This was obviously because they were emitting light themselves. This light soon drowned out the morning light on the horizon, a thousand stars quickly turned into a thousand little suns, and the world of Three Suns ushered in a glorious day. People on the earth raised their hands to the sky, forming an endless grassland of arms.

The Sanyang fleet began to accelerate, moving solemnly across the sky, passing over the top of the giant moon that had just risen, casting a blue halo on the mountains and plains of the moon. The cheers subsided, and the people of Sanyang World silently watched their hope fade away in the western space. They could not see the ending in this life, but in four or five hundred years, their descendants will receive news from the new world. That will be the rebirth of Sanyang civilization. Luo Xiaofei watched silently with them until the square array of a thousand stars shrank into one star, until the star disappeared in the western night sky.

"Ding! The Sanyang Civilization's expedition to the New World has begun, and the fleet is on its way..." the mechanical broadcast of the Daimao System came out.

"System system, stupid system, how far is the earth from our Sanyang star?" Luo Xiaofei called frantically in his mind.

"Ding! One hundred light years" was the mechanical broadcast of Daimao System.

"System system, stupid system, how long does it take to reach one hundred light years?"

"Ding! Theoretically, the fleet's fastest speed is 10% of the speed of light. If you just do mathematical calculations, it will take 1000 years to reach it." Daimao System's mechanical broadcast.

"System system, Dumao system, how long does it actually take to arrive?"

"Ding! First of all, you need to have an interstellar fleet. Secondly, you need to have the technology for interstellar travel. Then you need to install a strong magnetic field collector at the front of the spacecraft to collect antimatter in the universe while sailing and collect enough energy. If everything goes well, If so, it will arrive in a year." Daimao System mechanically announced.

"System system, stupid system, what is antimatter??"

"Ding! Matter is a substance composed of atoms in which protons have a positive charge and electrons have a negative charge. Antimatter is just the opposite, with protons having a negative charge and electrons having a positive charge. Under normal conditions, antimatter exhibits the same physical laws as matter , so antimatter can also exist normally in the material state.

But when positive and negative protons or positive and negative electrons meet, the two substances will annihilate. After the annihilation of matter and antimatter, all matter will be converted into energy, which means that the ratio of matter into energy is 100%.

Such an energy conversion ratio is more than a hundred times that of nuclear fusion reactions, without any pollution or by-products. If antimatter could be produced or collected in large quantities, space travel would become extremely easy.

Creating antimatter is not realistic. What if antimatter is collected in the universe? Can it meet the needs? Although the universe contains a lot of matter, the total amount of matter within a certain range even reaches a terrifying order of magnitude. Under normal circumstances, the density of matter in the universe is very low.

In other words, if we are in the universe, no matter which direction we sail, there is a high probability that we will not reach any planet in our lifetime. The scale of the universe is very large, so large that we cannot imagine it.

If a strong magnetic collector is installed at the front of the spacecraft, can antimatter be collected? Theoretically, it is feasible. Stars eject matter into the universe anytime and anywhere, and antimatter protons will also be ejected into space. There is a certain amount of these antimatter stored in space.

However, it is very difficult to collect enough antimatter in space. It is even more difficult than ionizing seawater to collect deuterium and tritium. The energy of antimatter annihilation is very attractive, but this collection method is difficult to maintain the operation of the antimatter engine.

Converting energy into plasma flow, the planetary engine obtains energy through the fusion of heavy matter, and then converts the energy into plasma flow. The plasma flow jet obtains reverse thrust and generates sufficient power. Therefore, whether it is an antimatter engine or a fusion engine, it is equivalent to installing a plasma jet at the tail of the spacecraft. "The mechanical broadcast of Daimao System.
