True yeah. Seems like the simplest to start with would be one more dimension though. I don't know enough about string theory to know why they always add so many more dimensions. Seems a bit data-fit-oriented but maybe short-sighted. I mean it's likely, like the OP article linked here sort of indicates, there's some sort of symmetrical structure. So maybe an electron moves through one or two other dimensions. But yeah, maybe string theorists know stuff I don't.
