No Roger, In string theory dimensions are conserved but can undergo extreme modification such as in compactification where formerly orthogonal dimensions become embedded in 3D space in spite of what Brent thinks. However, the string theory monads that result from compactification have many of the properties that you ascribe to unextended realms. Because of BEC and instant mapping effects, the entire collection of monads in the universe may behave as though the existed at a single point despite being extended. Richard
