greywolf wonders: hi, gw that is a perceptive question! please try this on for size: the two terms are often used as synonyms, yet "dimension" is burdened by some confusing baggage. when a person mentions an extra dimension it carries the idea that this dimension is off somewhere in a strange, twisted limbo of invisible space. in string theory the extra dimensions are imagined as some infitesimal microscopic realms not good for much of anything -- except as a helpful mathematical expediency. (i'm sorta reaching beyond my descriptive grasp here... ) the term, density, best describes the layered octave structure we think of as the 1st through the 7/8th. we are self-aware and conscious in the third density here on earth. but superimposed and intermixed -- so to speak -- in the same apparent space is found the whole complement of extra densities...(and some strange variations of 'time' complicate the situation beyond my primitive grasp of things) (also, you might do a search on the book site here on divine cosmos for info concerning the physical vacuum ... also called the zero point field ... which i suspect is --or an aspect of -- what the ra calls intelligent infinity) so, try to picture this: all is vibrating like mad...with different frequencies/waves interwoven. all is connected... any ripple we cause in our living is instaneously 'transmitted' rippling throughout the cosmos -- up, down, sideways, whatever -- its as if there is no spacial separation component whatsoever... have an idle thought, blow your nose ... and the whole cosmos is aware, and effectively modified by it. yep! i would conclude that our sense of privacy is apparently more apparent than real. ultimate cosmic sized embarrasment! there is one misunderstanding that needs to be cleared up. we speak of the higher densities in a way that makes them seem more rarified (after all we can't see them) than the grossly "dense" earthly abode where we can actually reach out and grab things. but in fact the higher densities are increasingly more dense, consisting of a type of ultra vibrating solidness far beyond one's imagination. wolf, re-reading what i've written makes me want to erase it and let someone more qualified step in to do a better job. hmmm nah. most likely they would screw it up also. i'll leave it as is and invite the experts to fix it up and make it right. my bestest, bbb (help! i've fallen up and can't get back down!)
