Potentially blowing everything up seems to be a running thing.

I think Eirin almost succeeded in putting the entirety of the Earth in a jar. Or maybe just Gensokyo. Or Earth [i]and[/i] Gensokyo. To stop people from the moon getting down to Earth.

Lunarian method for originally colonising the moon: manipulate quantum probabilities so everyone that needs to be there is there. I have no idea how this works.
