Although... in my mind, they're not really curled up extra
dimensions per se. Rather, that there's far more space than we
can see and measure. Not curled up into strings but expansive,
in an "outward" trajectory with far more "space" than we can
imagine. In short, rather than going smaller, I'm thinking
bigger. MUCH bigger. Maybe string theory encompasses this and
I've misunderstood it. But it always struck me that they were
trying to fit more dimensions in smaller spaces whereas I'm
thinking of expansions into much larger spaces than we can ever
know are there. Not useful for scientific inquiry I'm sure, but
it's a fun brain game.
