Muma said: "How can this be seen as more advanced? ”

David's external computer said: "Just watch more science fiction movies." ”

Muma said: "The single ride is also a warp engine? ”

David's computer said, "Yes, the design pictures are almost identical, but the size is different. ”

After the computer finished speaking, a three-dimensional cross-sectional view of these vehicles was projected.

David said, "What is energy power? ”

David's computer said, "Electricity." ”

Mulma said, "How is that possible? Looking at the picture, how can these machines be supported by large batteries or generators that can drive energy at the speed of light. ”

David said: "That should be the problem of battery technology, my computer, how is their battery technology. ”

David's external computer said: "You must be very shocked, according to the analysis of the existing data, according to the calculation of the same cubic centimeter battery, the amount of power that can be stored is 100,000 times that of the current human technology. ”

Muma said, "What do you mean? ”

David's computer said, "It has to start with Cullen." ”

Muma covered her face and said, "Okay, thank you, no need to continue." ”

David said with a smile: "You usually don't study hard, indeed, if it is really a warp engine, plus they have such an amazing battery material technology, then the charging technology must be very strong, theoretically allowing the vehicle to reach the speed of light." ”

Muma said: "I also said in your human science fiction novels that I heard the Qiuqiu music player read aloud that the bottleneck of some technologies is not in the process, but in the material, just like your ancient jet engine vent that burns old oil, which cannot withstand the heat emitted by the fission of modern nuclear energy. ”

David said, "Your description is wrong, but the truth is correct. ”

Muma said: "That's not what you guys are at the same level as writers like 18 Kai Novels, what kind of stuff are you writing!" ”

David said, "Humph! Tell you not to read those messy web novels, you just don't listen. ”

Muma said: "Didn't you say that I only read it when you told me to read more?" ”

David said, "I'll settle accounts with you later." The last time I saw you, you were reading an ancient Chinese novel called "The Galaxy is Not as Good as the Peach Blossoms", also known as the ghost "Soul Star Brigade", what can you learn? The author still dares to call himself a professor without shame? Phew! Don't look at it again! ”

Muma said: "Okay, okay, don't digress, Mr. David's computer, no, in that video, why don't they use these faster-than-light vehicles to go to the earth, but use what shells to launch the cloning warehouse or something, it's the same low-end as the way humans come here, uh, I mean relatively low-end." Hehe, in your eyes, our card control is really even more scum. ”

David's computer said, "I looked, there is no answer or content in this computer that you described." ”

David said, "Where did they come from? Can you see it? ”

David's external computer said: "In addition to scientific and technological knowledge, there are also humanities materials, I took a look at the planet hologram, and the terrain and landform shown in it are definitely not Proxima B, nor is it the Earth." I have no way of knowing where they are, so I have no way of knowing where their planet is. It should have been deliberately concealed by them, because I looked at some pictures and videos, which also had knowledge of astronomy, but after I analyzed and investigated, I just didn't find any clues about the location of their own planet, and I will see if there is any such content after the text is deciphered by me. ”

David said, "Let me see what the planet they live looks like. ”

Immediately, the projection screen in front of me showed the whole picture of a planet.

I saw that the main color of the planet was light green, mixed with some blue.

Muma said, "Haha, this is definitely not the blue of the earth, nor is it the blue blue of the sunny side of Proxima Centauri b that you have taken from the satellite you have seen for me. ”

David said, "The earth is blue, but it's not the color of the earth itself. Since the Earth's surface is covered by 71% of the ocean, the blue color of the sea is determined by the composition of sunlight and the nature of the seawater. Sunlight is composed of seven components: red, orange, yellow, green, cyan, blue, and violet. They are arranged from left to right according to their wavelength, with the longest red light on the left and the shortest violet light on the right. Red, orange, and yellow have long wavelengths and are easily absorbed by seawater; The wavelength of purple light is very short, and it is mostly reflected by the sea surface; Only blue light and nearby green and cyan light can penetrate into the seawater, fold in the seawater, and then be fully scattered by the water molecules, and then reflect the seawater blue. At the same time, due to the presence of a large number of salt ions in the seawater, the scattering of light is enhanced, making the seawater appear blue. Therefore, the earth is a blue planet. In addition, Uranus and Neptune are mainly composed of hydrogen, helium and methane, while a certain concentration of methane is more conducive to the absorption of red light and the scattering of blue light, while hydrogen and helium have almost no effect on visible light of all wavelengths, so their color looks like the sky of the earth. As for Proxima Centauri, it is because, according to the above theory, the sunny continent here is larger, and it is covered with more vegetation, which is combined with the ocean, so it appears blue-blue. On the dark side, we can only conclude through analysis that if a giant turns it 180 degrees to face Proxima Centauri, it should be dark blue. ”

Muma said: "Although I know every word you say, but after connecting them, I don't understand what you said. But if I say a word, I can choke you, even if what you see must be true? The video can be photoshopped. ”

David shook his head and smiled, "Okay, I'm not as good as you when it comes to poor mouths." My computer, switch the field of view to the planet, zoom in a random point, not so fast. ”

The image in front of you, similar to the Google Map of the Earth, can overlook the Earth from the perspective of space, or you can find a point and zoom in all the way to the ground.

As the "lens" zooms in, you can see that most of the planet's land is covered with vegetation, and between the land, there are a few waters that resemble oceans or lakes at all.

Later, I found that many parts of the planet are cities, and the high-rise buildings in the city, both on the top and on the sides of the buildings, are densely planted with various vegetation.

Even the ground between the buildings is grass or low plants.

Although the image is still, many of the vehicles of various sizes shown above can be seen floating between buildings and in the sky.
