The Return of the Black Technology of Immortal World

You must know that the nature of the gravitational force generated in the distortion of space-time caused by massive objects is the same.

But looking at the gravitational field, we can find their differences, because the gravitational lines of objects with small masses are different.

In fact, there are no gravitational lines in a real gravitational field.

Just like in a magnetic field, there are no magnetic lines of force, but they evenly cover the nearby space.

Magnetic lines of force are just some easy-to-observe traces formed in the magnetic field by people using magnetic powder.

Gravity lines are naturally the traces produced by the gravitational field in some special substances.

It's just that this trace is hidden in dark energy and cannot be seen by the naked eye.

Gravity lines, like magnetic field lines, are closed. From this point, we can see that although different gravitational lines are actually the same thing, they just differ according to distance, mass, angle and sparseness of the gravitational lines. The degree of density will vary.

Once the gravitational line is found, the gravitational direction of the gravitational thruster can be placed in the same direction as the gravitational line. In this way, the maximum traction can be obtained, allowing the spacecraft to quickly change its flight direction.

"This gravitational line is very obvious. Why hasn't it been found on the Blue Star?"

Yang Qing looked at the dark energy image in the observation radar again and asked.

"On a blue star, gravitational lines and magnetic field lines are mixed together, and there is no way to distinguish them. Only in the universe, where magnetic field lines are insufficient, can the existence of gravitational lines be observed."

Xiao Ai said with a little grievance.

"Forget it, pay attention to the frequency of dark energy that can display gravitational lines. After we get to the moon, we will create a special instrument and we can easily display gravitational lines without worrying about interference."

Yang Qing said.

Once on the moon, his job obviously added another aspect, which was to transform the escape spacecraft on top of the spacecraft into a pure refrigerant-free engine aircraft.

Now with the discovery of gravitational lines, the fat spacecraft that looks bloated can now have flexible and changeable flight methods in addition to protective covers. Even the manned flying saucer left at home can also fly after modification. For more than half a century, there have been numerous flying saucer legends about various incredible flying skills such as sudden stops, rapid acceleration, and ninety-degree turns.

When we get here, we are already very close to the moon. Although the moon disappears from our eyes again, when it reappears, the place where it will meet the spacecraft will be between the Sea of ​​Tranquility and the Sea of ​​Steam. On the moon land.

Sure enough, many beautiful things can be seen from a distance, but not up close.

They took off on July 11th and were delayed for four days on the road, so by this time, the moon had already entered the dark night and began to face away from the sun.

Although it receives the reflected light from the blue star, the surface of the moon is not particularly dark, but it is dark and looks like a demon's lair.

Those craters hidden in the darkness, as well as the moon sea, seem to have countless monsters waiting inside.

Fortunately for Yang Qing, he didn't have many surprises in such an environment, but Zhao Yuxi was different. It was fine for a short while, but after a long time, he would always have some kind of shuddering feeling.

Time was advancing slowly, and the spacecraft also entered the deceleration process. Under the control of Xiao Ai, at the last moment, the speed of the spacecraft was reduced to zero, and it kept up with the speed of the moon's autobiography, passing over a large area of ​​desolate land. The land flew towards the predetermined location.

By this time, the outline of the earth could no longer be seen. The monitor showed a vast expanse of gray-black land everywhere.

Behind them, a satellite had been quietly released long ago. It was equipped with a high-resolution optical telescope and flew along the lunar orbit, turning into a real lunar satellite.

It is equipped with a repulsion engine, which can flexibly change orbit, accelerate, and stay above the spacecraft at any time. Combined with Blue Star's many years of observing the moon's map, it gives the spacecraft the best navigation.

Suddenly, the spacecraft suddenly fell from the suspended state, and it did not stop until it was more than ten meters above the ground. This was the place where they decided to stop.

Ten kilometers away from this location is the Sea of ​​Tranquility, and on the other side, about thirty kilometers away, is the Sea of ​​Steam, which is relatively small, like a lake.

The reason why we stopped here is purely because there is nearly ten meters of lunar soil on the lunar continent below.

After billions of years of solar wind and direct impact from cosmic rays, the rocks on the moon's surface have long been corroded and weathered, turning into extremely fine gravel, with countless glass-like materials among them, which were formed by asteroids. Something thrown over after the first impact.

There are all kinds of minerals in it, but the most important thing is missing, which is the retention of organic matter. Moreover, because the moon has no atmosphere, there is no vital oxygen retained in it.

The lunar soil has become extremely delicate due to years of corrosion. Also because there is no atmosphere, they have never rolled. Except for large moonquakes or asteroid impacts, they have not moved.

Therefore, the particles of the lunar soil broken from the rock are like newly broken glass, sharp and strong.

Therefore, when walking on the moon, these lunar soils are also a big trouble. Not to mention the extremely fine lunar dust, which can almost reach the nanometer level, and can easily penetrate into every mechanical equipment that is not completely enclosed.

But at this point, they are still not smooth and delicate, but still have sharp edges and corners.

Therefore, mechanical equipment on the moon must be specially protected from dust, and more attention must be paid not to raise excessive lunar dust, which may easily injure oneself.

Such soft lunar soil is naturally not suitable for the landing of a spacecraft. With the spacecraft's mass of three million tons, even if the gravity on the moon is only one-sixth of the Blue Star, it still weighs half a million tons.

Similarly, the density of the lunar soil is only one-sixth that of the Blue Star, and it cannot withstand the pressure of the spacecraft.

Landing a spacecraft is not a simple matter, because the composition of lunar rocks is different, and the ability of weathered lunar soil to withstand pressure is also different.

If the spacecraft falls and the ground breaks, causing the spacecraft to roll over, it will be a huge trouble.

Not to mention the damage caused to the hull by the rollover, there is no such a big crane here that can lift the spacecraft.

So after hovering more than twenty meters high, the spacecraft opened a side door, and several construction machinery were hoisted down from there.

Very ordinary excavators, forklifts, and bulldozers are not much different from their counterparts on Blue Star.
