Hi! This board got yet another new non-physicist, me! Besides from being largely a layman when the formulas get too complicated, I've been very interested in physics pretty much for all my life. I just never taken it to a (semi-) professional level, and became an IT guy instead. So, you're not dealing with some esoteric nutjob here that just came to know what physics is, but most of my insight came from popular science sources, such as various popsci-books, wikipedia articles, TV documentaries, lecture videos on youtube/fora.tv and such. Oh, and please forgive me my occasional slip ups, I am german, and might spell a few things wrong, or produce grammatically interesting challenges :) My actual question. I've always found string theories rather appealing, and like to spend some philosophical thoughts on it (this is one case, where the hard math is well beyond me, so I unfortunately am limited to philosophical thinking here), and came up with some things that, as I found out recently, are pretty well described by the http://en.wikipedia.org/wiki/Randall–Sundrum_model" [Broken] (more precisely RS2). Now, before I spend more potentially stupid thought on this, I'd like to have a hint at to how much this theory is accepted as viable or possible among the ST guys, or in general even. Is there anything that makes this theory cumbersome, and puts it onto the brink of disregard?
