Dancing Circles on the Horizon of Events

"Waltz. It's that plan, but as adjusting the general position of the moon is done with Mr. Lucia's metastatic magic, fine tuning —— for example, fine tuning the position, or adjusting the speed -- what do you do around it? Are you going to do all that with metamagic, too?

That allegation by Deprexa implicitly said that "metastatic magic is not possible alone". It has a reason for its metastatic magic properties.

Metastatic magic is the magic that moves objects. That was a story limited to a relatively short distance on the planet, which was only perceived by a convenient degree of magic that, from the user's point of view, could travel in an instant.

But actually traveling in an instant on a planet is not that simple of a story. Because the planets are rotating, because the velocities vary depending on the latitude, simply moving the coordinates in a linear fashion, because from the law of motion volume preservation, the surgeon should be dragged by the planet's rotation and blown away. Of course, even if you subtract the kinetic energy generated when traveling.

To avoid that, metamagic incorporated a variety of safety devices. For example, the ability to adjust the amount of motion, even if the speed is different from the destination. Alternatively, such as the ability to prevent long distances from being transferred in order to avoid being affected by rotation in the first place…. Because of that, people can move safely. Incidentally, this function was not incorporated by someone, but acquired by organisms, starting with people, in the course of evolution.

Therefore, when trying to move the moon, it was not possible to adjust to the amount of motion in the moon, but simply to move the coordinates. That doesn't make any difference, even if Lucia's transfer magic was actually a special transfer magic that could be called drag-and-drop magic.

In other words, even if I brought the current moon to the side of the planet without any thought, which was increasing in speed in the direction of moving away from the planet, if I let it go, I would go away on my own. Specifically in the direction of the Sun pulling all the planets in the star system with enormous gravity......

To prevent that, it was necessary to give the moon some amount of motion and adjust it not to stay away from the planet, but that was another difficult story as well. Especially in the case of a snowdome-like moon, it was easy to imagine that applying force from the outside would entail great difficulty while keeping the drifting atmosphere from being lost. Deprexa worried about it.

On the other hand, Waltz, who was directed to that question, also seemed to understand what Deprexa was worried about.

"... it's time, and if it's snowing, can't the moon be left in space like this?

"The status quo, that moon, is being pulled in the direction of the sun. To fight gravity, you'll need speed or mass, like a hammer throw, but to do that, that month, you'll have to give exercise energy from the outside. Otherwise, that moon will be swallowed up by the sun in decades. It's the same thing you have to do."

"That's hard..."

How can I move the moon non-destructively, when Waltz has a head--,

"Um... Master Waltz? May I offer you a suggestion?

—— Julia, who was there, opened her mouth.

"Yeah, what kind of suggestion?

"I thought if Master Waltz stood on the surface of the moon, disassembled the earth, turned it into energy, and released it into space, we could change the orbit of the moon... how about that? You said that before, didn't you? He says it's a big deal to do mass energy conversion so we don't change the orbit of the planet."

"... Julia. That knowledge, where did you get it?

"... it's an intelligence officer's preference." Kiri.

"... Cortex."

Behind the Director of Intelligence (?) The fox daughter leaping in. It was obvious that she was teaching all sorts of things to the Julians. It should be noted that that person, even if turned to Waltz's jito eyes--,

"What is it ~?

—— He seemed to give me an extra look. Apparently, she intends to spread the theory of relativity to this world.

"... nothing good though"

Initially, when he came to this world, he was a waltz who didn't intend to divulge any extra information or knowledge, but he decided it was no longer too late, and he seemed to have decided to acquiesce in Cortex's actions. It goes without saying that Waltz himself is responsible for the information leak.

Then Waltz got back to business.

"Well, sure, I can stand on the surface of the moon and adjust the orbit..."

Waltz looks at the cold moon, hopefully. From her eyes (camera), the surface temperature of the moon ranges from minus 60 degrees to minus 80 degrees. I wasn't talking about a cold place. On top of that, the snow falling on the surface is C02, not H2O. In other words, it is dry ice.

"It's cold, it's definitely cold. That moon......"

Though machines, as she had lived like a human before, going to the poles where people couldn't live was something I didn't really care about. Moreover, because of the polar poles, there are no companions; only one must go.

But if we don't do something about the moon, the planet has no future...

"... is there any other good plan?

…………

"... ha, okay"

In the end, Waltz was alone, standing on the surface of the cold moon, to fine-tune the orbit of the moon.
