Space... as we know it in 2011... :)

Whatever point you think you just tried to make failed - You said String is a subset of M when in fact M is a subset of String.

Nonononono string is a component of M not a potential M or ToE itself.

Or not.
http://en.wikipedia.org/wiki/M-theory

In theoretical physics, M-theory is an extension of string theory in which 11 dimensions are identified.

Really? Because what you're saying i said is pretty different than what i said. Let me put it out there in a different way. Without M you can still have string. Without string, there can be no M. I don't care how string->superstring is organized by topicality on wikipedia; string IS a component of M.
