Yang Meng also felt the same way about Xiaoguang's sigh.

As human beings living on Earth,

If this speed is placed on the earth, it is beyond the scope of human understanding.

In the kingdom in which he lives,

There is an ancient city called Xi'an, and there is also a new city of Shenzhen with developed technology.

The distance between the two places is extremely far in the eyes of ordinary people, and the distance in a straight line reaches about 1,700 kilometers.

But at one hundredth of the speed of light, which is 3,000 kilometers per second,

It only takes 0.57 seconds to get from one city to another.

Of course, such an exaggerated speed is inappropriate to be placed on Earth,

If a supersonic plane hits a bird during flight, it will cause a lot of damage to the aircraft.

In this state of 8800 times the speed of sound, not to mention hitting something,

Just by the friction and collision with various gas molecules in the air, there is no material that can resist the high-temperature wear caused by friction with air for a long time.

Even if there is such a material,

On the spatial scale of the Earth,

There is also not enough time and distance to accelerate the aircraft to such a speed at the limit of what humans can withstand gravitational acceleration.

In the universe, although it is close to a vacuum,

But there are still some particles and dust with tiny masses.

When the spacecraft touches these tiny substances with mass at a certain speed, it will still cause imperceptible damage to the spacecraft.

And when the Boundless Orient he was riding was moving forward in the universe,

It's not just one hundredth of the speed of light

At a speed of 5,000 kilometers per second, it is not enough to reach the Rutan galaxy at a distance of 12.36 light-years from Earth in a time frame of 100 years.

If you sail through the universe at a faster speed,

The problem of wear and tear on the ship is also more serious.

After Xiaoguang understood the problem of speed and wear, another problem popped up,

"What kind of technology did you use to achieve this speed?"

For such a question, Yang Meng just dealt with it simply, and did not answer it in detail.

After all, the knowledge of aerospace is too complex and difficult to explain in a short time.

Regarding Yang Meng's answer, Xiaoguang did not continue to ask, but continued to lie on the radioactive material and kept making strange sounds.

Although he didn't explain the principle of the thruster to Xiaoguang,

But Xiaoguang mentioned the thruster, which made Yang Meng think of something,

At the time of the last communication with the Earth, on the side of the Earth, a technical update was made to some of the equipment on the spacecraft,

Among them is the update on the thruster.

"Xiao Yi, what was updated on the thruster last time I communicated?"

"In this communication, the ground is optimized for ion-assisted propulsion units.

According to the experimental data on the earth,

When the propulsion unit is improved, the ship's current maximum speed can be increased by 0.0036%! ”

"Speed up?"

Although the increase is small, the speed of the ship itself is large, and this increase is already considerable.

But thinking of the lack of external materials for the spaceship, this increase in speed made Yang Meng even more distressed,

After all, the faster the speed, the faster the spacecraft wears out, and this wear and tear is also one of the important reasons for limiting the spacecraft to infinitely close to the speed of light.

"Anyway, let's break this metal down before we can figure out anything else?"

"Xiao Yi continues to explore other planets in the Rutan system?"

"Understand, the probe has been going according to plan!"

……

Time continues to pass,

This giant piece of metal floating in the universe has basically been decomposed by the efficient decomposition of small lights.

And the green light on the metal block also disappeared into the universe.

At this time, it was already the ninth month since Yang Meng left Lutan B.

It was also his 276th day in the microgravity environment of space.

On this day, Yang Meng was operating a robotic arm on the spacecraft and was putting the finishing touches on resource recovery.

And Xiao Yi, who has been monitoring his physical condition in his body, issued a reminder:

"Note that due to the environmental impact of weightlessness, your skeletal muscles and body functions have fallen below the sub-healthy average.

Please enter the modified anomaly gravity centrifuge in time to recover and correct! ”

Hearing such a reminder, Yang Meng didn't care, but replied lightly:

"Got it!"

As an astronaut, a weightless environment can lead to a decline in human body function, as an astronaut, he naturally knows.

This situation has been taken seriously by human beings since they landed in space.

Therefore, for astronauts who are in a weightless environment for a long time, they will maintain the healthy function of the body in various ways.

While he rests according to his routine,

The hibernation chamber where he is located will rotate at a certain angular velocity in the manner of a centrifuge.

For the human body in the cabin, a certain gravity is applied to simulate the gravitational environment on the earth.

In addition to the recovery of gravity while sleeping, Yang Meng also uses some exercise machinery to maintain his body functions.

But even so, staying in the cosmic environment for a long time still can't perfectly solve the damage caused by weightlessness to the human body.

Yang Meng knew this, but he didn't have time to go to the device prompted by Xiao Yi to recover now.

And the reason why I don't want to get into that device,

Or is it because the anomaly centrifuge requires him to go into a cryogenic hibernation state,

In that state, he would soak in the repair solution and then perform a 10-day gravity intervention before he could leave the anomaly gravity centrifuge.

At such a time, it is obviously inappropriate to go dormant for ten days.

He needs to reclaim resources and repair the ship, and the more important reason is because of Xiaoguang......

Just when Yang Meng rejected Xiao Yi's suggestion to resume dormancy,

The last piece of metal was also recovered into the ship,

With the last piece of metal coming back there is a small light,

Seeing Xiaoguang come back,

Yang Meng left the command cabin and floated to the front of the barochamber.

As the hatch opened, Yang Meng saw a small light flickering at a certain frequency,

After a few months of familiarity, this kind of flickering frequency, without Xiao Yi's translation, Yang Meng can also read some of it.

He seemed to see a trace of loss in the flickering frequency of the small light, as if he had lost something he loved.

And when Xiaoguang saw Yang Meng, he immediately put away the strange flickering frequency on his body, and then asked:

"Well, the last matter has been recovered, can these resources allow you to embark on your way back!"

Hearing Xiaoguang's question, Yang Meng shook his head gently,

Seeing Yang Meng shaking his head, Xiao Guang could read their flickering frequency, and he could also discern the meaning behind this simple action, so he flashed again and asked:

"Still lacking resources? What are your plans? ”

"Are you going to?"

Yang Meng recalled that during this period of time, other planetary exploration data transmitted by various probes,

He looked out of the porthole to a spot,

And Xiaoguang followed Yang Meng's gaze and saw that there was an extremely bright point of light outside the porthole.

This point of light was interfered with by the spacecraft's lights, and under the red light of the Rutan star, it became the only exocele object that could be seen in the porthole.

And Xiaoguang naturally knows what this celestial body is:

"It's a scourge! You wouldn't want to go there, would you? ”

"No! It was a terrible and risky decision! ”
