In "The Three-Body Problem", human beings discovered the fleet of the three-body civilization four light years away by analyzing the trajectory in the dust cloud.

Now, the eyes of hundreds of millions of people in the live broadcast room have also penetrated the distance of four light years and seen the blue earth.

The difference is that the technology of the 69th century is far more advanced than the human civilization in "The Three-Body Problem", and it can clearly zoom in on the resolution to a level beyond imagination.

Mountains, rivers, Gobi, forests...... and slightly vague urban agglomerations, all of which come into view.

This is the Earth four years ago.

The history of mankind has long passed......

As the picture continues to zoom in, the originally vague urban agglomeration gradually becomes clearer. If you look closely, you can barely see the endless flow of people and vehicles in the streets.

【I'm Nima!Mingkun City!】

[I saw the Science and Technology Museum.] 】

[The science and technology museum four years ago, now the backyard has been built early. 】

[It's still a little hard to see, can you zoom in a little more?]

[I was born in 17 years!]

[You will become a fine in 21 years. 】

[If you fly two thousand light years away, will you be able to see the Qin Dynasty?]

[Theory is possible, but the light information at such a distance is lost, and it is impossible to magnify it so clearly.] 】

[Maybe the products that will be evaluated in the future will be able to do it.] 】

[Then I want to see the Qinglou. 】

[I'm going to see it too.] 】

【Green House +1......】

"The magnification is at its limit. ”

When the image is zoomed in to 1 scale, the telescope technology built into the spacecraft can no longer guarantee clarity. If you continue to zoom in, you will only produce random simulated fake pixels due to insufficient light information.

Turning to the side and giving the best observation angle to the interactors, Chen Yu spread his hands regretfully: "The distance is so far that I can only barely see the traffic." And where there are clouds, you can't see anything. I feel that if the distance is only two light-years, I should be able to zoom in to see people's faces. ”

"Speaking of this, I suddenly came up with a brainstorm, if in the future, thousands of such telescopes are installed one light-year or two-light-year around the solar system, and the monitoring of crime should be better than the eye of the sky. Wherever a case occurs, fly directly to that location, look at the 'historical record' from a day ago to two years, and you can directly solve the case. ”

[You're such a genius. 】

[Theoretically feasible, practical fucking.] 】

[Wipe your ass with Victoria's Secret.] 】

[What kind of mentally retarded metaphor is this?]

[I can't hold it back, where did the female assistant go?!, no one is paying attention?!]

……

"She's so hot......"

Earth, Chen's house, living room.

Chen Yike held his mobile phone, and saw Xing Biqi's crazy rise in the amount of attention around his neck, and the roots of his sour teeth itched.

I don't know what method the vast number of netizens used, in just a few hours, they dug up all the information of the interactors of this live broadcast of "Super Time and Space Evaluation".

Among them, the most popular is the women's clothing boss whose ID is Luoxia. Secondly, it is the exquisite-looking Xing Biqi.

The original 6 fans also rushed to 2.1 million.

instantly became popular all over the Internet and became an Internet celebrity.

Under the latest news, the comments exploded.

【Goddess!】

【Meimei Meimei ......】

[@碧空白旗, are you interested in developing in the entertainment industry? 】

[You are the real god of Europe!]

[Can the gift given by the UP owner be sold? The price is negotiable. 】

[It's a pure sister paper, it's powdered. (Dog's Head)】

[Such a beautiful goddess, can she pull a big lump of poop, right?]

【……】

"If others knew that the UP master was my brother, I would definitely be even more popular!"

Pouting, Chen Yike slid his phone to click on his scarf page, and sighed deeply when he saw the 12 fans.

"Sure enough, men like the new and hate the old. ”

"Obviously I ...... first"

……

Proxima Centauri galacies 4.2 light-years away.

The white light and shadow slowly glided through deep space, away from the red dwarf.

After passing through 300 astronomical units, the spherical spacecraft that represents the majesty of humanity finally left the strong gravitational range of the red dwarf, and immediately began to travel faster than light.

"I don't know if you've noticed. Inside the spaceship, Chen Yu pointed to a building in the Mingkun city of the earth, and said: "A tall building on the left is rapidly decreasing in height, this is because we are moving away from the earth at the speed of light, resulting in the phenomenon of time reversal. To put it in one word, it's upside down. ”

"The faster we go, the faster we see the Earth 'going back in time'. When the spaceship flew out a thousand light years later, I could see the Earth a thousand years ago. ”

[Rewind the praise!]

[It would be better if I could zoom in a little bit, I just want to see how the pulled out poop is retracted.] 】

【？】

[You can also look at the noodles you eat and spit them out again.] 】

【？？】

[The rescued wounded are stuffed back under the car.] 】

【？？？】

[The world is so beautiful when it is reversed.] (funny)]

[To be reasonable, the more people, the greater the chance of sand sculptures. 】

[No one cares if there is a bug?] It's so fast that it's faster, why can you still see the picture of the earth?!The light can't catch up with your spaceship, okay?】

Raising his wrist, Chen Yu was stunned when he saw this barrage, and then explained.

"I saw some of the audience's doubts. That's a great question, since the spaceship is already faster than the speed of light, why can we still see the scene behind it? It stands to reason that photons can't catch up with us, shouldn't it be pitch black behind us?"

"That's exactly the right idea. When supersonic speed, nothing is heard from the rear either. But how does the ship see the effects from behind?"

The answer is actually quite simple. ”

Chen Yu took a few steps forward and reached out and knocked on the wall of the ship that could not be seen by the naked eye: "I also said before that the transparent spaceship that everyone sees is actually not transparent. It can be understood as a layer of high-definition screen. The so-called front, back, left and right scenery is nothing more than the light signal collected by the external 'camera' of the spacecraft, and then the light signal is converted into a video output and played inside the ship. ”

"Just like the maglev train I once reviewed, the glass windows in the passenger compartment are just screens. ”

"So when the spacecraft travels faster than light, the 'camera' collects all the photons it can receive. Some of these light information come from the front, and naturally there are also from the rear and left and right. Therefore, we can see our surroundings clearly even at the speed of light. It doesn't mean that because the light behind us is slower than the ship, we won't be able to see anything. ”

[Sweep the dead!]

[Can you still do this?]

[Technology is amazing. 】

[This wave of sophistry is full marks.] 】

[Look!The Earth is turned upside down!]

When the spacecraft traveled to fifty times the speed of light, everyone could see the Earth as it was speeding upside down.

"It was great to be able to enjoy the rest of the place. Chen Yu immediately manipulated the telescope and moved the camera to the location of the capital of China with great interest: "Show the global audience the ** ......"

But then, no matter how he zoomed in, he could only see layers of dense and opaque gray haze......

170 million viewers: "......"

"Hmm. ”

"It is worthy of being an important weapon of the country! Not only can it prevent missile targeting, but it can also block the prying eyes of higher civilizations......

(Note: Writing a chapter a day is really slow to this extent...... The transformation failed, and it was extremely irritable. Some themes are really only suitable for brain-opening, and they can't change the direction of the plot.

Don't toss, start the fourth watch tomorrow, and finish the book in one wave. ）
