I understand from popular books such as those by Brian Greene that among the stock in trade of string theorists are as-yet-unexplored dimensions that are squashed into tiny geometrical configurations called Calabi-Yao shapes.
Do stringy folk ever consider a reverse process, which might be called, say, the unfolding of dimensions? Especially of ordinary ones like the two kinds that we are familiar with; time and space? If so, is it understood how the unfolding of ordinary dimensions would manifest itself to us? What would it do to metric coefficients, for example?
This is a probably a well-trodden path in string theory that I am sadly ignorant about. I'm asking to be guided to a starting point in these forums, or elsewhere on the web, suitable for someone who is quite uneducated about string theory, but is not entirely mathematically illiterate.
