I just don't want it to be actually antimatter because those Marisa fanboys will inevitably start bringing that up in future powerlevel debates. :V
Why, yes, I'm a believer of a "low powerlevel" Touhou universe myself.
It doesn't matter though. You will never be able to change the way people perceive Touhou. That is after all what gives Touhou a quality many other video games don't have - You can imagine it as whatever you want it to be. It's a dream world. It's how the man himself calls his creation. He has given some lore, but he usually won't butt in if you make something weird out of it (unlike most others would with their own creations).
Some people have a rather dark image of Touhou, others view it as silly or carefree. You can any time go ahead and draw a few fairies doing some flower viewing or shooting little pellets of plastic, if that is what your image of it is. And you certainly shouldn't be bothered by what another fan thinks of the games or the powerlevel of characters. You cannot dictate others what to think and they can't do that to you, either. If a "powerlevel" discussion distresses you, just don't participate in that discussion. Simple solution to a simple problem. Not everyone is holding these discussions anyway. :3
Not to forget that those powerlevel discussions can be really void in their meaning anyway, as Touhou still is a game. It shouldn't be forgotten (but often is) that it will eventually involve game elements that are there for balance reasons (countering any spellcard with a "bomb" for instance looks more like a gameplay element than a lore element; a few select characters beating up entire Temples and hells and alternative dimensions filled with Youkai while exhausted does, too).
Specifically for the Antimatter topic - The game is set in an alternative reality with alternative history, alternative sources of energy and power. If ZUN said Gensokyo has more gravity than the real world for some reason it would be that way, because it's not a realistic setting but an alternative setting. It is already a fantasy setting anyway, given that a lot of fable and fairytale creatures appear in it. Nothing would go haywire because ZUN gives the word Antimatter a different definition than our worlds Antimatter. I mean, Utsuho is a walking nuclear core kind of, that could also never exist in reality. Just think of that and then take it easy.
