An Wen listened to Director Shen talk about system issues for three hours.

He was dizzy when he listened.

Such a social system problem is really difficult to understand with his experience.

However, after listening to it, he understood one thing, that is, the country is playing the next big game of chess.

He didn't care about this, it didn't affect him much anyway.

"It's past ten o'clock, let's rest early."

An Wen ran away after speaking, he found out for the first time that Director Shen had the potential of Tang Seng, and he was too able to say.

"Alas...... Why are you leaving? I'm not done yet. ”

Seeing An Wen leaving, Director Shen was a little regretful.

Nothing was said all night.

The next day, after breakfast, An Wen drove the spaceship to the outside of the Dawning Galaxy.

"Mastermind, release the optical imaging equipment."

"Okay, Commander."

Who's Ann Wen ordered the spaceship cargo hold to open.

Thousands of robots fly out of the warehouse with a variety of equipment.

Half an hour later, a massive bee-mesh optical device unfurls on the periphery of the Dawning Galaxy.

"Mastermind, point the device at the earth and collect light wave information."

"Okay, Commander."

Huge optical devices are aimed at the Earth and begin to collect light waves coming from the direction of the Earth.

Soon, a projection of the earth appeared on the holographic projection screen in front of An Wen's eyes.

However, this is not the current Earth, but the Earth of about 200 years ago.

The Dawning Planet is 201 light-years away from the Earth, and he set up optical equipment outside the planet, and the image of the Earth taken is almost 200 years ago.

"Amplify the capital of China." An Wen said.

Earth model zoom in.

The capital of 1821, that is, the capital of 200 years ago, appeared in front of An Wen's eyes.

But...... After zooming in, the capital looks like a bunch of mosaics.

Through the mosaic, you can vaguely see the scene of the capital.

This scene is a real-time image, but what appears to be a mosaic that is constantly changing.

"There is too much information lost, and no matter how strong the optical equipment is, there is no way to completely restore the scene at that time."

An Wen muttered as she thought about how to solve the problem.

"Let's add more optical equipment and collect as much information as possible, as for the information that cannot be collected, we can only rely on quantum supercomputing to make up for it."

Thinking of this, An Wen traveled directly to the other world and asked Shuguang to make 100 sets of optical equipment.

He returned with the equipment, and then let the spacecraft make a space jump, to the cosmic void on the same timeline, and place the optical equipment again.

When this set of optical equipment began to collect information, the capital on the holographic projection screen was a little clearer.

"This time it's really a little clearer, and it's good to have an effect."

In fact, such a way of casting a wide net is a bit silly, but if you want to restore the historical scene to the greatest extent, this way of relying on big data optical information simulation is much more realistic than using the brain-supplemented restoration of quantum supercomputing.

And the more this optical information is collected, the faster the supercomputing brain will be supplemented.

Even when the order of magnitude of the information reaches a certain level, he can play these video materials as documentaries.

"Keep setting up the equipment."

If there is an effect, Anwen will be motivated.

For an entire day, he piloted the spaceship, constantly dropping optical equipment around it for 100 light-years.

But one day is definitely not enough.

Therefore, after An Wen returned to Dawning Star, he specially sent someone to put the equipment.

In the afternoon of the next day, when the surrounding optical equipment reached 28 sets, the capital on the holographic projection screen had become very clear.

Of course, this clarity is, at most, HD.

But it doesn't matter, the supercomputer can be made up by the brain casually, and it can be turned into 4K image quality in an instant.

"Tell Director Shen to come over."

An Wen said to the mastermind.

"Okay, Commander."

After a while, Director Shen came to the bridge.

"What's the matter?" Director Shen asked curiously.

At this time, An Wen was mysterious and secretive, and he didn't know what he was doing, but An Wen didn't take the initiative to say, but he didn't want to ask.

"Look at this."

An Wen said with a smile, pointing to the holographic projection screen.

Director Shen turned his head to look, he hadn't paid attention to it before, thinking that An Wen was watching a movie.

Now that I look at it, I realize that what is playing in front of me is not a movie.

"This is the Forbidden City? Which Qing court drama is this? The scene restoration is really good, but this perspective is wrong. Director Shen watched it for a long time, but he still didn't understand.

"This is the Forbidden City 200 years ago, and the pretending criminals in the Imperial Garden should be Daoguang." An Wen said with a smile.

Although he also wants to enlarge the characters, the problem is that the faces of the characters in the back are all supercomputered.

The information carried by light waves has been floating in the universe for 200 years, and there is too much missing.

Even if Anwen uses powerful scientific and technological means, it cannot be 100% restored, and the missing information can only be made up by relying on supercomputing.

It's easy to talk about architecture or anything, but there's no way about the characters.

Don't look at the bird's-eye view in front of you, the characters in the Forbidden City are vivid.

But if you look closely, you will see that these people all have similar faces.

Because all the moving characters may be a pixel collected by a certain set of optical equipment, and this pixel is finally restored by supercomputing simulation to become a character.

The scene in front of you, except for the building, is real, and the other characters and plants are all filled in by supercomputing.

"The Forbidden City 200 years ago? Light? Director Shen was stunned.

It took him a moment to figure out what was going on.

"Can optical devices collect such accurate information?" Director Shen was very surprised.

"If it's the whole picture of the earth, it's very accurate, but the more you zoom in, the less accurate the information is.

Now we are looking at the magnification of the highest multiple, and if we continue to magnify the characters, it will not make any sense at all.

Because the movements of the characters are all simulated by supercomputing, and continuing to zoom in is to watch a movie.

If it is reduced to the size of a city, it is still possible, at least the flow of people in the city is real. ”

An Wen shrugged and said helplessly.

It's just the information collected by the optical equipment, and it's not about adjusting the timeline and reversing time to see the historical scene, and it's good to be so clear.

"So, if you send optical equipment billions of light-years away, wouldn't you be able to see the image of the Earth forming?" Director Shen said with a big brain.

"Dream, billions of years away, the little light reflected by the earth, I don't know where it went." An Wen shook his head and replied.

"How far back can you collect information?"

"It's hard to say, the farther away from the earth, the more information will be lost, I'll try to find the universe with that star field around it and there are no obstacles, and when the time comes, I put the optical equipment over there, and there should be more information that can be collected there."

An Wen thought for a while and said, even he was not sure how many years ago the information could be collected, but at least no more than 10,000 years.

At a distance of 10,000 light-years, the various radiations in the universe are enough to wipe out most of the information carried by light waves.

At that time, even if the information of the earth is collected, it will be all mosaics, all relying on supercomputer simulation, and there is actually no difference between the brain supplement, and there can be some mosaics as evidence.

The next day, An Wen drove the spaceship away.

Last night, he really found a place suitable for optical observation through the star map scanned by the deep space probe.

From there, you can directly observe the orbit of the solar system over 30,000 years, without any planets in between.

There must be a lot more information stored there than there is here in the Dawning Galaxy.

"5,000 years of optical information is not bad, and a lot of information can still be collected with multiple sets of optical equipment, so the timeline starts here."

An Wen tried it and found that although there was little optical information 5,000 years ago, there were still some of them, and it was still possible to make up for it with supercomputing brains.

In this case, he has been recording since 5000.

"When all the information is collected, I will make a documentary, called Up and Down 5,000 Years, which is the original history."
