so like, the Large Hadron Collider is meant to find the Higgs Boson, which translates to 'magic energy of the fundamental universe' which created Gensokyo. If they find Higgs Boson, they will find Yukari's gap. and hence... they will find Gensokyo.
BRILLIANT!
I mean, how else would you explain this energy? how else would you explain the gaps?
if you piece them together it just makes sense.

The other I find interesting is...
Just who is it who manifactures them poofy hats?
It makes no sense, consider the degree of fashion of Gensokyo with everyone else (humans for example) are typicall pre-Sengoku era perhaps, and it also makes no sense they have the means of making soft cotton fabric like poofy hats which can be worn comfortably. Logic suggest that at the time, people normally wore straw hats.
Imported hats and important wear such as samurai armor is mainly reserved for the big names, and soft hats? don't get me started.
This means, there is at least one already unveiled youkai who has the ability to manipulate hats.
