Mimiyuria took a deep breath and covered her eyes with her hands, holding back that she didn't faint. Pen ~ fun ~ Pavilion www.biquge.info Well, in fact, her age is already eighty summers old, and I have emphasized this many times about this, but I don't know why this little human girl who is only sixteen summers old insists on calling herself "sister", no matter how she explains it, she refuses to change her words, which really makes the elf nerve-wracking.

"Uh, little Linya, I'm five times older than you! you can't call me sister!" Mimiyuria said as she decided to make one last effort. But unsurprisingly, this human girl, who was only a small baby in the world of elves, deliberately ignored her own words as before. In the end, she could only give up and vomit blood and acquiesce. It's the same as this dwarven girl who has become accustomed to it.

Ignoring the poor elven girl's protests, Linya used the magic of light, the magic of water, and the magic of earth to summon three magic orbs and levitate them. "First of all, let me assume that the largest ball of light is the sun, this medium-sized ball of water is our Noah, and the smallest ball of earth is the moon......"

But she had only said a few words, and Mimiyuria was already stunned. "You...... Do you know three types of magic? No, no, I remember you used fire magic! You also used our natural magic! This, how is this possible?" Mimiyuria opened her mouth in a daze, and the two long pointed ears also trembled, and she looked so cute in fright.

"Hmm...... Actually, I don't know earth and dark magic yet. That's why I can only summon such a magic orb from the earth system. Linya replied truthfully. But her answer made the Elven Ranger completely stupid. People with magical talents, whether they are humans or elves, are one in a hundred, and magicians who can practice both types of magic at the same time are even rarer. The reason for this, if the Lord really had to mention the principles of magic and other professional knowledge, it may not be enough to say it for a long time.

And this human girl can not only practice a full range of magic at the same time, but what is even more terrifying is that she actually uses the magic of light, water, and fire at the same time!! pay attention, it is used at the same time! God, she was not exploded by the magic energy in her body?

She suddenly realizes that this human girl is mysteriously terrifying. If you really don't have a dazzle...... Among the elves, I am afraid that only that legendary figure can compare with it. "What's wrong with that?" asked Makriel with some confusion on the side, and Mimiyuria suddenly sneered secretly, dwarfs are dwarfs, a bunch of magical idiots!

"Uh...... It's nothing. Realizing that she had inadvertently exposed some kind of ability that ordinary people should not have, Linya hurriedly pulled the topic back, "Our Noah, like the sun and the moon, is essentially a big ball, and we are actually just very, very small people living on this super big ball." I think this can be understood, right?" the other three girls nodded as if they didn't understand.

"The sun is the center of this cosmic space, this star system, the most massive and can shine and heat, and Noah is a planet revolving around the sun, yes, it is a planet that is constantly rotating in such a circular orbit. The moon is Noah's moon, and it has been revolving around Noah in a circular orbit. Well, to use an analogy...... For example, a king has a noble knight who accompanies and guards him day and night, and this noble knight has an ordinary soldier who is always on standby...... That's how the relationship looks, but this example doesn't seem appropriate......

It took one year, or 365 days, for Noah to revolve around the sun. Since Noah is circular, when sunlight hits Noah, the intensity and direction of the light received vary from place to place, so there will be a change in temperature. In addition, Noah himself is not vertical, but rotates obliquely at a certain angle, so when you go around the different areas of this circular orbit, there will be different seasonal changes in spring, summer, autumn and winter due to the change of light intensity.

At the same time, Noah himself is constantly rotating itself around the earth's axis, and the time of rotation is one day, that is, twenty-four hours. That's the real reason why we see the sun rising and setting on Noah -- it's not the sun revolving around Noah, it's Noah himself!"

"What? is this possible?" cried out the three girls, of course, in disbelief. "Little Linya, you're not joking with us, are you?" "What we see is obviously the universe revolving around Noah!"

Well, science popularization is really a chore, and after a lot of saliva, Linya finally reluctantly convinces them, in fact, at best, half-believed, to make them fully believe this, it is simply an impossible task. Linya suddenly regretted that she shouldn't have nothing to do at all, and after saying so much, she ended up getting endless trouble for herself...... But now she's struggling to ride a tiger. In the puzzled eyes of the three of them, Linya could only continue to speak.

"The moon revolves around Noah in this little circular orbit for a month, or thirty days. The moon, like Noah, does not shine on its own, so the light we usually see is essentially just the sun's light reflected off the moon. Now, let me tell you why the moon waxes and wanes.

Please see clearly that when the moon turns between Noah and the sun, we can no longer see the moon on Noah because of the angle at which the light is reflected - the sun is blocked, the moon itself does not shine, and our eyes must have light to see.

And when the moon turns behind Noah, we can see a full full moon on Noah - because the light from the sun to the moon is reflected by the moon in its entirety, and it can be seen clearly on Noah. And when the moon turns to either side of Noah, we can only see half a moon - again because of the angle. And in the same way, the phenomenon of the full moon and the crescent moon is also caused by this reason.

Due to the spherical nature of the moon and Noah, they are practically the same, with half bathed in the light of sunlight and the other half shrouded in darkness without sunlight. If you stand on the moon and look at Noah, you will actually have the same round profit and loss. ”

Linya manipulated three magic balls to create a simple model of the solar system, and while explaining it in the most popular language and examples possible, the three girls were extremely intelligent and soon seemed to understand something. But the three of them unexpectedly didn't say anything this time, and what Linya didn't know was that her last sentence "If you look at Noah on the moon, it will also be the same" made the listener have an inexplicable feeling, among which Susanna's feeling is the most profound, but of course she will not show it easily with her calm personality.

Susanna's eyes seemed to have become more strange when she looked at Linya, and her mood was really mixed now. Noah was half dark, and she could understand and accept it. But the moon is also half dark...... Then she had to think back to the mythical story of the bard just now.

"Oh yes, there's one more thing I forgot to mention. If the sun, Noah, and moon are on the same line, there will be some kind of extremely rare astronomical spectacle...... When the moon moves between the sun and Noah, there is a small chance that the sun will block the sunlight from the sun to Noah, and without the sunlight, the sun will look like it is obscured by something dark from Noah's view—this is a solar eclipse.

When the moon moves behind Noah, there is a small chance that Noah will block the light from the sun to the moon - without sunlight, the moon looks like it has been swallowed up by something dark from Noah, which is a lunar eclipse.

No, what I'm demonstrating now is these two situations, when there is a small chance of an occasional occurrence when the three balls are in one line. The nature of solar and lunar eclipses should also be said to be caused by changes in the position and angle of the moon, but due to the distance, this probability is very, very small. Taking advantage of this opportunity, Linya simply continued to do popular science.

"What? The eclipse is because the moon is blocking the sun, and it is the moon that is blocking the sun?" Mimiyuria was completely stunned at this time, and today she felt that her brain capacity was a little insufficient. "The lunar eclipse that happened last month turned out to be because Noah blocked the sun, and the dark shadow that ate the moon turned out to be Noah himself?"

"Yes. I think everyone will be very frightened when this happens, but in fact, the waxing and waning of the moon is the same as the eclipse of the moon, the rising and setting of the sun, the rising and setting of the moon, spring, summer, autumn and winter, etc., in essence, this is an inevitable natural phenomenon, and it has nothing to do with any god, so there is no need for everyone to panic. Linya's whim of popular science knowledge made the three girls completely petrified.

"Actually, I don't want to comment on the mythical story of that bard. Right and wrong are always relative. In this world, no one can know everything. What we know is really only what we want to know, or what we want to believe. Truth only exists in the heart of every human being. Believing or not is a matter of the heart, and you don't have to pay much attention to what I say. Feeling like she was talking a little too much, Linya decided to cool them down at the end.

Back in her tent, Suzanne was still in a state of distraction until she fell asleep in her arms. Linya didn't know what to say, it was a bit difficult for a person with a medieval level of knowledge to understand the scientific knowledge of the end of the Age of Enlightenment and even the industrial and information ages.

"Sister Susanna, in fact, I am telling you this so that I can dispel your doubts and have a good night's sleep, I don't want you to lose sleep all night!" said Linya, caressing Susanna's beautiful cheek.
