True Nanotechnology
However, these are all outdated.
And to be serious, these are not real Nanobots; at most they can be called nanomachines, and adding the word "human" to them mostly adds an element of exaggeration.
Because these nanomachines in the medical field are not intelligent at all, and are far removed from the word 'robot'.
Even in 2100, scientists made breakthroughs in the field of nanomedicine, successfully developing a large number of precise and controllable micro-machines and achieving precise nanomedicine treatment. However, these cannot be called 'Nanobots' because they are actually drug delivery tools or nano-drug delivery systems.
We are still a long way from creating true 'Nanobots'.
However, precisely because of this, humans are not unfamiliar with the term "Nanobots".
However, this familiarity can be divided into two types: one is a true understanding of 'Nanobots', and the other is only superficial.
The former was quite shocked by Yu Nanfeng's words, while the latter had an expression that said, "It doesn't seem like such a big deal."
Yue Yuan belongs to the former group because he has not lived in vain all these years. He has not spent his days in hibernation; he has almost always forced himself to learn all kinds of knowledge, so he certainly knows what a real Nanobots should look like.
What's even more outrageous is that these Nanobots are used for mining, and they handle the entire process from collection, separation, and refining.
Each step requires extremely high intelligence and precise operation. Just as the chemist said before, the most likely way to collect metals in this way is to break the chemical bonds between compounds through some mechanism.
The technology involved is self-evident.
This requires each Nanobots to have an Intelligent Program, an energy supply system, metal recognition capabilities, metal separation sites, and a series of other microscopic features.
It is important to know that most metallic elements exist in the form of atomic bonds, which means that the operating parts of these Nanobots are at least at the atomic level, otherwise they would not be able to separate metals at all.
Humans do not know the size of each unit in the 'Silver Mist', but from the phrase "Nanobots," we can roughly guess that the basic unit of the 'Silver Mist,' that is, the individual Nanobots that make up the 'Silver Mist,' is at least at the mist level.
Otherwise, it wouldn't have resembled fog so much.
As for the size of fog, the smallest fog droplets are only about 1 micrometer.
One micrometer is 1000 nanometers.
Based on this calculation, if the smallest unit of the Silver Mist is a 1000-nanometer Nanobots, then the components that make up this Nanobots must be at least at the picometer level, only in this way can its functional parts manipulate the bonds of metal atoms.
The picometer level is for components, but what about the basic units that make up Nanobots components? Wouldn't they be at the Femtometer level? Just like a chip is very small, but the circuits that make up the chip are even smaller.
To create intelligent programs on such a tiny scale is no different from being a god to humans.
Moreover, it's hard to believe there are so many of these things.
How did that civilization create so Nanobots? The more Yue Yuan thought about it, the more he felt the gap in technological strength, and the oppressive feeling brought by that insurmountable gap came over him.
This unbelievable thing is actually a mining tool.
That's too luxurious.
What kind of existence is that Unknown Civilization that creates the Silver Mist? Could it be that they "use golden hoes to farm"? The story of "the emperor using a golden hoe to farm" suddenly popped into Yue Yuan's mind.
Poverty limited his imagination, making it impossible for him to envision what a civilization that could mine with real Nanobots would be like.
First there was the civilization that blew up stars, and now they've encountered a civilization that Nanobots to mine minerals. Yue Yuan couldn't judge which of these two civilizations was more advanced, but that didn't stop him from sensing the malice emanating from the depths of the universe.
What sins has humanity committed to deserve so much suffering? In our Solar System, everything was fine until the sun suddenly exploded. After barely surviving and reaching another distant Star System, we encountered this damned Nanobots.
In his heart, Yue Yuan had cursed the civilization that created the "Silver Mist" more than ten thousand times.
Why not leave behind a Silver Mountain? That way, when humanity becomes prosperous one day, they might even thank us. But why did they have to leave behind something as dangerous as "Silver Mist"? Of course, Yue Yuan also knew that any curses were just impotent rage, and that the civilization that left behind "Silver Mist" was likely in trouble, otherwise they wouldn't have abandoned such a mining planet.
But no matter what, and whatever the truth may be, it's not something that humans can touch right now.
"A gentleman takes revenge even after ten years. Ross 154-4, 'Silver Mist', one day, we humans will return. We will never forget the blood debt of our two hundred and eighty-one compatriots." Yue Yuan buried this hatred deep in his heart.
The seven days passed quickly.
After all the personnel and salvageable supplies and materials were brought back to the Hope, the Hope, with its aging gait, slowly flew out of the orbit of Ross 154-4 Planet and traced a path in space toward Ross 154-7.
Because of the fear of the 'Silver Mist', the Hope didn't even dare to change its circular orbit to an elliptical one. Instead, it activated the Fission Thruster while still on the circular orbit and used the engine's power to push itself off the orbit.
This method of acceleration without relying on Planetary Gravity is quite laborious, but fortunately, Ross 154-7 is not far from the Ross 154-4 Planet.
Ross 154-7 is only 1.82 Astronomical Unit from its Main Sequence Star, while Ross 154-4 has an orbital radius of 0.18 Astronomical Unit. Theoretically, the shortest distance is 1.72 Astronomical Unit, but ideal routes are not always available when traveling in space.
For example, Ross 154-7 is currently positioned on the opposite side of the Main Sequence Star relative to humanity, so humanity would have to make another trip after setting off to rendezvous with its orbit.
Humans have become highly skilled at adjusting attitude, changing orbit, and entering orbit within a galaxy. The Hope spacecraft took just over twenty days to dock in orbit around Ross 154-7.
This planet is very small, with a diameter of only 5333 km, smaller than Mars. It is the smallest planet in this system and is likely composed of scraps from the galaxy's evolutionary process.
Its orbital period is very long, a full 8.1 Earth years. Living on it, one year is equivalent to 8.1 Earth years. It has a thin, almost negligible atmosphere, mainly composed of nitrogen.
The surface temperature is -234.1 degrees Celsius year-round.
Due to its great distance from the Main Sequence Star, the solar energy available here is an order of magnitude less than that at Ross 154-4, but its rotation tilt is extremely large, at 80°12′ 41′′. The Rotating Shaft is almost aligned with its Main Sequence Star.
This brings one benefit to mankind: the solar panels can always be used because there is an area on them that is perpetually sunny.
It also contains a large amount of frozen water, from which humans can directly extract water through water purification processes. In addition, it has an ice-covered satellite with a diameter of 1,101 kilometers.
