Chapter 328: Travel through time!

Found evidence of the possible existence of advanced alien civilization, normally Chen Yu should be ready to return to the voyage quickly and bring the same kind back to Earth safely.
But the existence of the r-type deep space ship makes him full of confidence.
Mankind in 6877 was definitely an advanced civilization spanning multiple planetary systems.
Chen Yu does not believe that Proxima will have a stronger civilization than human beings in the 60th century.
In the world of science and technology, the changes in every era exceed the sky and the earth, let alone the gap of thousands of years.
Therefore, with only a civilian ship, Chen Yu has the confidence to hang down the second-class civilization under the "Kardashev" system.
And this Trisolaran galaxy will not have a second-level or higher civilization, otherwise the solar system just a short distance away would have been colonized...
What's more, if the blue light ball is really a detector, then the existence of Chen Yu and his party has been detected. For the safety of the earth as far away as four light years away, he is obliged to investigate clearly and solve problems that may threaten the earth.
Standing in place, Chen Yu looked at the dazzling twin stars ahead, and his brain began to make various plans.
"I don't know if a star exploded here, four light-years away, will it affect the solar system..."
After a while, the spacecraft broke away from the scope of planetary gravity, and Chen Yu immediately manipulated the hull to push the normal sailing speed to the extreme and begin to revolve around the planet.
Looking at the rapidly rotating red planet under his feet, Chen Yu explained to the camera, "I'm scanning this planet to find out whether it has life in 360°. The spacecraft has two built-in scanning systems, one for the analysis of the same matter. The instrument and a circular polarization life scanner can cooperate with each other to complete the three-dimensional reconnaissance of the planet, which is very efficient."
"Analysis of the same element material, the theory was born in 3155, and the actual use is about 4000. As the name suggests, it is used to detect different nuclides of the same element with the same number of protons and different numbers of neutrons. Through the detection of these elements, You can keenly detect whether there are more than the standard amount of'artificial' manufacturing elements in the planet. If there are, it means that there is a smart civilization here. And the level of civilization has reached the atomic level."
"Circular Polarization Life Scanner, the theory was born around 2019, and it was actually used in the 30th century. The detailed explanation of circular polarization is very complicated, involving physics, optics, and various complex formulas. I will just say it briefly. It doesn't matter if you understand."
"The amino acids that make up human proteins are all left-handed versions of their respective molecules. When light interacts with these long chains, it becomes circularly polarized. Its electromagnetic waves will spiral clockwise or counterclockwise and travel outward. The so-called circular polarization scanning is to detect whether there is circular polarization in the planet. If there is, it means that there are living things here."
"Two systems, the latter determines whether living things exist, the former verifies and determines whether living things reach the level of intelligent civilization."
"Of course, it is ironic..." Chen Yu shrugged. "According to the knowledge I have obtained, the circular polarization life scanner was actually used for the first time, not for searching for alien life, but for war. The gathering place was determined by satellites. , And then attacked in a targeted manner. One hit and one accurate, it was cool."

[As expected of human beings. 】
[As expected of human +1. 】
[True mother is a genius...]
[It's over, the reminder of the up master, countries must start to study. 】
[Maybe it started long ago. 】
[The last issue, please cherish it. 】
During the explanation, the r-type deep space ship completed a circle of the planet, but neither system sent any hints.
Chen Yu was expressionless, turned around and continued flying along the equator.
After a few minutes, another flight was over, and there was still no sign of life.
"It looks like it's not on this planet." Chen Yu turned the spacecraft around and flew towards the two big stars. "It's normal. It's really not suitable for life here. Let's go to the double star to take a look. I guess there should be there. Quite a few planets."
"The journey to Tianmen II a and b is very long, and it is necessary to start the super-light speed navigation. But to start the super-light speed, you have to run out of the gravitational range of the red dwarf. Therefore, this period of time takes at least ten minutes."
"Then take advantage of these ten minutes, let's make a very fun game."
Then, Chen Yu pointed the direction of the solar system, "Look there, there is a star, right?"
The camera looked over at the same time as everyone in the boat.
"This beauty." Chen Yu walked to Xing Biqi in the corner. "I noticed that you have been looking at that star. Do you know what it is?"
"Solar system."
"How did you know?"
"I...I remember its location."
Xing Biqi looked a little nervous when everyone watched intently. And thinking that hundreds of millions of people would see her in the live broadcast room, my mind was dizzy.
"Yes, that is the solar system."
Patting the the shoulder, Chen Yu walked into the crowd and talked eloquently, "Someone must be very curious. We walked four light-years in four hours. Looking back, can we see the earth four years ago? ?"
As soon as this remark came out, the eyes of the interactors on the ship, the hundreds of millions of viewers in the live broadcast room, and the scientific researchers of various institutions all beamed!
This is an extremely interesting experiment for everyone.
"The answer is yes. The solar system we see now is the solar system four years ago, so the earth was also four years ago. With the telescope technology built into the spacecraft, most of the light information four light years away can be easily obtained. It is not a problem to restore the image of the earth through the filling of the 60th century model."
"Then start now and look at the Earth in 2017."
Chen Yu did what he said, without any verbosity, and turned on the zoom function directly in the direction of the solar system.
"Huh!"
"Huh!"
"Huh..."
As the distance gets closer, the solar system that originally shone like stars becomes like a full moon.
Jupiter and Saturn not far away are also clearly visible under the reflection of the sun.
"See? This is the solar system four years ago. The position of the planets is completely different from now."
With that, he continued to zoom in.
"Huh..."
The azure earth appeared in the picture...
[Great! 】
[The earth four years ago! 】
[I am crossing! 】
[Can you zoom in on the anchor? Look at the internal organs. 】
[Magic~EbookFREE.me~ I have decided! Learn astrophysics later! It's so romantic! 】
[Brother, believe me, I would rather go to study medicine than get involved in astrophysics. It's too late to look back now. 】
[This review is really high-energy throughout! It's the same as watching a movie. 】
"You are on the Earth in 2021, but you saw the Earth in 2017 through my live broadcast room. From a certain perspective, this is also a kind of time travel."
"But from my current position, I can't adjust the direction arbitrarily, so I can only see a corner of the eastern hemisphere, barely reaching the border of China. It should be... the boundary between Yunnan and Guizhou? Now continue to zoom in and test what can be seen by the spacecraft's telescope. degree."
When the words fell, he manipulated the screen to zoom in again.
Including Xing Biqi, everyone in the hall hurriedly moved behind Chen Yu, their eyes widened one by one, seriously waiting for the next magical scene...
