Sasang has too many unknowns, not only her, but also other sisters who grew up on technologically backward planets, and she asked: "Brother Jun, what is the Yang Domain?" Jun Xia answered all the questions, and said: "The Yang Domain is also the same as our Yin Domain, there are also people who have planets, but the Yang Domain has the opposite feeling of temperature. The space is symmetrical in the yin and yang domains, a bit like when we look in a mirror, and the outside and inside of the mirror are two symmetrical worlds. ”

continued: "It's just that the two domains of yin and yang are not in the same space, and it is not appropriate to use a mirror as an analogy. The scene in and out of the mirror can be seen in a space where the flow of time is displayed. In the Yang Domain, light simply cannot cross from the Yin Domain to the Yang Domain, and vice versa. The mirror image is just a hint to us. ”

He continued: "According to the temperature of our Yin Domain, the feeling of the people on the Yang Domain is that starting from the lowest temperature of the yin medium of minus 273.73 degrees, the lower the temperature, the hotter the people in the Yang Domain will feel, and the boiling point of the water on their side, if calculated according to the temperature on our side, is minus 647.46 degrees in our Yin Domain. ”

Although Sasang didn't understand what he heard, he asked again: "Brother Jun, do you earthlings know all this?" Junxia shook his head and said: "Earthlings don't know that there is a yang domain, let alone that the lower limit temperature of the negative medium is minus 273.73 degrees, and they don't even know if there is a negative medium. ”

continued: "Also, whether it is the yin domain or the yang domain, those electromagnetic waves use the medium of their respective domains as the medium of operation. Just as a horse-drawn carriage uses a road as its medium, a ship uses the relative water surface as its medium, and sound waves use matter as its medium. The medium of our yin domain is called the negative medium. The medium of the yang domain that is symmetrical with our yin domain is called the yang medium. ”

Zuo Sang frowned, and then asked, "Brother Jun, since the medium is invisible and intangible, how can you say that this can be discovered?"

Jun Xia explained: "In fact, if people pay attention, they can still find it, and even the temperature difference between the upper and lower parts of the negative medium is suggested. For example, the saturation temperature of steam at the critical pressure is 374.3 degrees, and we use this temperature to subtract 100 degrees of water from ice to boiling, which is equal to 274.3 degrees, and then subtract 273.16 degrees from 274.3 degrees, which is equal to 1.14, and divide 1.14 by 2, which is equal to 0.57. This 0.57 is the temperature difference between the upper and lower parts of the negative medium. ”

After that, Jun Xia ordered Peng Cheng to turn on some dim lights, and everyone in the recreation room of the prayer boat could look at each other again, and the feeling of loneliness was lost. Jun Xia's explanation, although some of the sisters here don't understand it halfway, but Zuo Sang still thanks: "Brother Jun, I still can't understand a lot of what you said, but I still want to thank Brother Jun!"

Junxia also saluted: "Because I don't tell you systematically, you haven't been exposed to the most basic knowledge of many terms such as electromagnetic waves and sound waves, let alone those temperature points, so it's normal to not understand, let's learn it slowly in the future, learn as much as you want, in the future, when you officially become a Shenying warrior, some major knowledge will be directly transmitted to your memory bank by high-tech methods, so you don't have to learn everything, or you will learn for a thousand years and 10,000 years without an end." ”

Zuo Sang smiled and said, "Brother Jun, did you say that you don't need to learn, and directly pour knowledge into your head, right?" Jun Xia smiled even more and said: "That's what it means, but it is a wrong understanding to be poured into the brain, to be precise, into the soul of the super-quality program system." It is best to understand the most basic knowledge that can be learned, because it is better not to instill too simple knowledge. ”

Sasang Yile said, "That's great, Brother Jun, isn't that move called Daigo empowerment?" As soon as Sasan said this, Junxia, Yilan, Kiyoshi and they all laughed. Yi Lan smiled while pointing at Junxia and said to Zuo Sang: "That's right, your brother Jun was enlightened by Daigo!"

After laughing for a while, Junxia said, "Okay, don't laugh, let's go to Yikong for a swim!" After that, Junxia ordered the prayer boat to go to the Yikong area outside the earth and stars, and Junxia ordered the prayer boat to extinguish all the dim lights in the ship, and it was dark inside and out in an instant, without a trace of light. Junxia introduced: "This is Otoku, and you can't even see the starlight." ”

In this kind of darkness, it is even more lonely, and Sasang asked again: "Brother Jun, where did those stars go?" Junxia explained: "Those stars are in the Uma, we are outside the Uma, and the outside of the Uma is the Oto, there is no medium in the pure Oto, and there is no medium for light to spread, so it can't be penetrated, and the space occupied by the Otoku in a domain is much larger than the space occupied by the medium in the Uma." ”

Sasang asked inexplicably: "Brother Jun, the light can't penetrate through, how do we get in?" Jun Xia explained: "In the B air, matter cannot exist directly, I have already said before, and our prayer boat is not made of matter, it is automatically grown by ethyl according to the design program by absorbing the ethyl essence in the space by itself, just like the process of our material people absorbing material nutrients from the most basic genetic program to adulthood, so the prayer boat is also alive, it is an ethyl lifeform. ”

Junxia continued, "To put it more simply, the prayer boat is grown from seeds. Ethyl lays out space, allowing the medium to exist in ethnine, and the medium lays out the space, allowing the substance to exist in the medium. Media are clustered, i.e., media like to be close together, but they don't like crowding. Substances not only like to be close together, but also tend to be crowded, which is called the cohesion of substances in a specific environment. ”

Junxia continued, "If there is no specific environment, matter is not cohesive. On the contrary, matter is discrete. Ethyl has neither clustering, nor cohesion, nor discreteness, and is a neutral existence, but there is overlap, that is, if there is more ethyl, it will overlap. ”

Junxia continued: "Ethyl itself does not solidify energy, so pure Eto-emptiness has no temperature. Due to the limitations of our scientific and technological level, we earthlings call the space without matter a vacuum, but in fact, that is wrong, and the space without the existence of matter is roughly divided into medium space and B space. ”

Zuo Sang asked again: "Brother Jun, the substance, the medium, and the ethyl substance, is there any quality after the ethyl substance?" Junxia explained: "Yes, there is also superquality." Super-quality and point-in-time flow programs are the two most basic elements that form a flow space. Therefore, what can exist directly in the space of flow at the point in time is ethyl. The medium cannot exist directly in space, that is, the medium must exist in space. ”

Junxia continued: "There is no absolute vacuum, the vacuum is filled with ethyl, so the medium can naturally exist freely in space. If we don't have the protection of the prayer boat, as soon as we go out to the outer emptiness, it will melt away very quickly, and almost all the energy stored in the matter will be released and turned into a medium.

Junxia continued, "So, matter is a cornucopia of energy. I grew up on the earth, and the technology on the earth has not yet reached the point where the energy is obtained by using matter to dissolve into a medium, otherwise we earthlings would not have to use backward material nuclear energy. As for what is material nuclear energy, this will be discussed later. The upper limit temperature of the medium is the bottom temperature of the existence of the substance, that is, the temperature at which the substance exists. ”
