Douluo see you soon

The main engine of Natural Selection is ignited, and controllable nuclear fusion has become a relatively mature technology after years of technological accumulation. Although true propulsion without working fluid is still far away, interstellar navigation is no longer a problem.

The propulsion medium of Natural Selection is high-energy particles that accelerate close to the speed of light. There are two symmetrical high-energy particle accelerators inside the spacecraft, which can save the working medium to the greatest extent.

According to the law of conservation of momentum, it is not difficult to see that the faster the propelled material is, the greater the acceleration it will bring to the spacecraft.

If it is an ordinary spacecraft, even if it saves propulsion medium, it will be difficult to achieve interstellar navigation. The reason is very simple. If a traditional rocket wants to carry more things, it needs to carry more fuel. However, the fuel itself

It also has weight. If you want to transport this fuel, you need to carry more fuel.

However, the newly loaded fuel still has weight, forming a vicious cycle. The mass of material that a huge rocket can carry may only be a pitiful little bit. Most of the fuel's power is used to carry other fuels.

As a result, it will be difficult for a rocket-propelled aircraft to achieve interplanetary navigation. If you want to fly that far, the total amount of fuel you need to carry is simply terrifying.

That kind of cost is probably just transporting one person to Proxima Centauri, and the resources consumed can bankrupt a civilization.

The black technology in another world is different. In this other world, space technology is rampant. If a traveler doesn’t have a space ring, it’s hard to talk to anyone... It’s embarrassing...

As for Chengying, he started his business by manufacturing storage equipment, so there will naturally be no shortage of such things.

Ever since, the problem was solved, and the vicious cycle no longer existed, because there was no need to worry about transporting fuel. In theory, he could even create and reserve a large amount of chemical fuel, and he could fly to Proxima Centauri with a chemical fuel rocket.

The propulsion medium and fuel carried by the Natural Selection can even propel it to sail thousands of light years.

A light year is the distance that light travels in a vacuum for one year, and the Douluo star's sun is only about four light years away from Proxima Centauri.

With such energy reserves, it is more than enough to sail to Mars.

In addition to the energy system and thrusters, an interstellar spacecraft also requires many devices, including life support systems and gravity simulation devices. The navigation system is also indispensable. Navigating in the starry sky is even more difficult than navigating on the sea.

Be difficult.

The only things that the spacecraft can use as a reference are the stars in the sky, and when the distance is far away, these stars are extremely small. If you want to judge your own position, you must accurately calculate the changes in the positions of these stars in the sky.

In order to overcome various difficulties, this spacecraft was delayed for nearly ten years before it was finally built. But this time, Cheng Ying planned to go to Mars with the ship himself.

His purpose is to leave a teleportation gate on Mars, so that next time there will be no need to drive the spacecraft back and forth so hard. You can teleport through the office.

But there was one thing that he couldn't figure out, and that was what the coordinates of space transmission were based on. You know, no matter which planet in the solar system, they are all rotating and revolving.

So here’s the problem. You left the coordinates here. The next time you come here, the planet under your feet may have rotated, or it may have orbited and left its original position. Then it should appear in space after teleportation.

.But the actual location that appears is the original place where you left the coordinates.

Even if we don’t talk about the rotation and revolution of the planets, the entire solar system is still in motion. If you think about it this way, the space coordinates should appear somewhere in the universe.

From this perspective, all space capabilities have big problems. If we have to forcefully explain this phenomenon, we can also say that space coordinates are positions in a certain inertial system, which can barely explain why there are

The coordinates will not suddenly go into space.

However, as the saying goes, practice is the only criterion for testing truth. In order to prevent himself from leaving behind space coordinates and accidentally teleporting to space later, Cheng Ying conducted a series of relatively rigorous experiments.

Designing experiments is actually not difficult. The practical purpose is to explore the performance of space coordinates in different inertial systems. When designing experiments, you only need to artificially create an inertial system. You cannot stop the earth from rotating and revolving. But a car

A train traveling in a straight line at a constant speed can easily control its speed and even stop it directly.

The experiment was conducted on a section of railway that was close to a straight line. First, spatial coordinates were set at the rear of the train to keep the train running in a straight line at a constant speed.

Then he jumped off the train and started teleporting.

The result is very amazing! After jumping off the train, the teleportation position is not above the rails behind the train, but directly inside the train.

This seems to prove that the spatial coordinates indeed move with the inertial frame. A train moving in a straight line at a uniform speed is regarded as an inertial frame by the spatial coordinates.

But this is only the first step of the experiment. The experiment is repeated for the second time. This time, the spatial coordinates are at the front of the train, so that the train keeps running in a straight line at a constant speed. The spatial coordinates are arranged, and then the train brakes urgently and transmits again.

If the spatial coordinates are set in the inertial frame, the location where the transmission occurs is on the rails in front of the train, and the location of this coordinate will continue to move in that direction at the constant speed of the train.

But it turns out that the location where the teleportation occurs is the location where the teleportation coordinates were originally arranged on the locomotive. This goes against the previous conjecture, and there are only two possibilities left. One is the spatial coordinate, which is actually a kind of substance. Left

in something.

Another possibility is even more terrifying, that is, the spatial coordinates are actually an idealistic setting. The person who arranged the spatial coordinates will only be transported to the location he wants to go.

It seems that the practice in the third part proves that space coordinates are material or set against one's will.

Now that the possibility of an inertial frame has been ruled out, time does not require a straight railway. Just a lunar car that can travel on the lunar surface is enough.

First, leave the coordinates on the car. Then let the car drive between supply stations on the lunar surface. Each time it passes a Buji station, a part is replaced and a transmission is performed to confirm the location of the transmission.

Keep driving until every part on the car is replaced with a brand new one. This was originally a philosophical question. But now it seems to have affected reality.

The results of this experiment will also determine the development direction of space technology.
