Dancing Circles on the Horizon of Events

"Or it will surely perish"

So affirmed the words of Cortex --,

"Just give me a minute. It is unacceptable to be told that it will all of a sudden perish. Too much clapping."

—— It was unacceptable to Alfania. Even if she was explained in order, her spirit was not fat enough to be accepted when suddenly she said, "The world will perish" and so on. It also seemed unbelievable to say that it would be doomed, because it was the people of a country who could not afford it.

It's just... Didn't seem to have listened and unilaterally disbelieved. Apparently, a second introduction by Waltz worked.

"... suppose their words are correct. Why would it lead to a development where the world would perish? It's just the moon's gone and that's it, isn't it?

Cortex answered that question of Alfania.

"There are three reasons to perish. One is because the moon is gone, and the tidal force -- uh, the power to spin the interior of the planet -- is lost, and the temperature of the planet's geothermal heat drops, resulting in less volcanic eruptions. With fewer volcanic eruptions, the amount of ash blocking the sun will decrease ~ … perhaps the temperature on this planet will rise rapidly"

"I'm not sure about that" hey kiriku "thing, but does a volcanic eruption decrease when the moon runs out?

"That's what they say. The stars always had the power to attract an object called gravity, and even if we use our hands to wing them, we can't fly because this gravity - so called gravity - is in the way. This gravity is found not only on this planet, but also on the moon that floats in the sky and on the sun, where the forces of those stars are intricately intertwined, causing volcanoes to erupt, earthquakes to occur, rain to fall, winds to blow."

…………

"Especially if you're the moon, the star closest to this planet. If it doesn't, it will have a huge impact on the crust of this star —— that is, on the phenomena that occur deep in the ground. Deep beneath the planet, something like a magma dissolved in a drool called a mantle is swirling, and that's what's energizing the volcano on this planet ~ … When the moon is gone, the mantle flows very poorly, and as a result, the eruption of the volcano drops dramatically"

"... It was a little difficult because it was the first time I heard it... but I knew what they were trying to say. But I still can't believe it. Why don't you give me a few more thoughts?

Alfania pours the green tea that was on her desk into the back of her throat. At that time, tea must not have been the only thing that poured in, but must have included something like unseen worry.

Cortex narrows his eyes to such an Alfanian reaction.

"Yeah, I don't mind, but won't you understand in a day or two ~?

"... are you so impatient?

"I can't be sure yet, but it was too late, because I regret it when ~"

"... do good"

"Now I'll explain the second reason why you perish ~?

"Oh... I don't know if I can follow you."

"At Master Alfania's pace, you just have to think slowly. Eh ~"

And Cortex resumed his explanation.

"Actually, not only planets and moons, but stars —— the Sun itself is moving ~"

"What..."

"In other words, by making a time leap, you can't throw away the possibility that you've fallen off the orbit of the planet. When that happens, you get closer to or away from the sun ~...... Either way, it's going to be a big deal. You know what happens, don't you?

"... if you get close to the sun, it gets hot, if you leave, it gets cold, you mean?

"Exactly. However, this story is not a certainty and I believe that we need to investigate it in detail from now on. This is speculative, but it has to do with not blowing away from the planet when a single user of an artifact makes a time leap ~ … I feel that way"

"... well. I want you to let me know when you know for sure. So what's the third?

"The third one is ~... when the second hypothesis as much as just now is not correct, it's a story of greater possibilities"

Cortex explains, pointing to the hologram Waltz kept displaying.

"What we were here is the part where the moon is. Let's just say that only the planet slipped out of there softly and moved to another position in the same planetary orbit.... Ooh ~? Wouldn't the moon chase you for losing your planet from behind ~"

"Hey, no!... So you're saying this star and moon is going to bump into each other someday?!

"Yeah, you're right. Finally, if the time jump that struck this planet was not a few hours level, but a few thousand years level, I don't know if it was behind or before, but it would be coming after this planet itself, not just the moon. Well, I don't think there's probably a thousands of years of level leap ~"

Cortex, who finished the whole explanation, exhaled loudly and dropped his shoulder. Though he spoke as if from person to person, for once he seemed to feel responsible.

Alfania, on the other hand, seemed to have heard less than half of Cortex's story at this point. Anyway, Cortex's story went far beyond the science and technology of this era. As for Alfania, even if Cortex was right, we didn't think we could do anything together.

The Alfania question was therefore summarised in one point:

"And what are they going to do to our elves?

Alfania with that and a surprising look on her face. At this time, her doubts about the Waltz might have increased to the maximum.
