As I said before:
Celestial bodies, such as the moon and the earth, are the soil where Aurora can take root. It’s not just the ‘ground’ of those bodies. It’s basically all physical substances that belong to it that can serve as soil. The Kagari (Earth) entry in the memory sectioin explains it quite well, really:
[quote]All living things have at least a tiny amount of aurora in them. Aurora likes to tie itself to physical substances, especially resources which have never been touched by aurora before.
When Aurora reaches other planets (from rockets or meteors or whatever), it has an enoormous quantity of fresh material to work with, so it tends to increase in strength and number rapidly, like bacteria. The farther it spreads, the easier it is for life to appear. You can think of it like flowers and pollen. In other words, this is how planets reproduce. [/quote]
Your comparison to a battery was close, but it didn’t account for Aurora’s capability of multiplying. Of course, the quality of the soil determines how much it can multiply, and how much life can be created. The earth had a crazy amount of different life forms while the moon could only ever produce one creature with its ressources, namely Moon Kagari.
Two factors are responsible for the death of the earth:
- Too low amounts of Aurora, which is insufficient for a re-evolution. It can be speculated that the human race is actively wasting Aurora.
- Decreasing quality of the earth’s ‘soil’ due to not only its usage by Aurora (Battery comparison), but also misuse by the human race. (Remember how environementalism is a core topic of Rewrite? ^^)
Decreasing quality means that less Aurora can be produced. The human race is gradually destroying the planet and wasting Aurora. But if Salvation happens, the circle of life will be interrupted for good.
This is the situation during Moon route: By the time the soil of the moon will run dry, the soil of earth will recover just enough for one last try at evolution. The dominant race created by that MUST find a solution for the problem. If they don’t, the earth will die again and the Aurora won’t be able to settle on the exhausted Moon either. The absolute end.
That scenario must be avoided at all costs, and a way of life to prosper must be found.
The blueprint experiments are mere simulations. A very detailed theory, a calculation, that has yet to be put into practice. But they’re not the real thing. The term blueprint is pretty accurate here. A blueprint of a house shows how the house should turn out if all implications and calculations are correct. It’s a model that tries to be as accurate and as close to reality as possible. The real house, however, is the thing that is built according to the blueprint. Things that you have not accounted for in the blueprint may become a problem for the house.
The moment when Kagari’s theory, the blueprint, was done was not the moment when the problem was solved completely. She merely made a plan that had yet to be executed. The execution of it is the terra route and its success depends on whether or not it’s executed properly.
Another example of a “real thing” is moon Kotarou.
[quote=“Naoki_Saten, post:43, topic:654”]
Moon Kotarou was created with Aurora from his previous alternate counterparts. As proof of that, he retained all memories and skills he had in those worlds.[/quote]
Imagine him as a house built from parts of other, very similar houses (pre-moon parallel versions of Kotarou). It would make no sense for, say, his supporting pillars to be made out of cut-out paper parts from the blueprint.
Moon Kotarou is made out of real parts and his memories are real as well. They are remnants of real Tennouji Kotarous that went through ‘life’.
If you condense a huge amount of Aurora around the blueprint, all you can get (if at all) would be multiple blueprints that exist on parallel planes. The blueprint would be the only thing with many versions. It would most certainly not result in the creation of huge parallel universes, with an earth, a moon, a solar system and whatnot.
“too big” or “too small” are vague things to say. What matters is the Aurora/surface area ratio. If there is not enough surface area to properly contain the aurora, multiple parallel universes are created in order to contain it.
I am saying that there was a time when the amount of Aurora on earth was so huge that parallel universes were created. That happened way before the story of Rewrite started. It could’ve been millions of years in the past. By the time common route began, multiple universes already existed. On earth. That’s where all pre-moon routes took place.
If parallel worlds were formed on the moon, then again, the moon would be the only thing replicated. There would be multiple moons existing on alternative planes at the exact same spot. To use those for her plan, Kagari would have to “dress up” these moons to look like the earth, atmosphere and all, then reconstruct Kazamatsuri and make sure that its inhabitants never find out that a huge part of the world as they know it doesn’t actually exist.
I’ll say it again:
It makes no sense for parallel universes to occur anywhere but on earth, and anytime but pre-moon.
