rrw4rusty Posted October 24, 2009 Posted October 24, 2009 Hi! Just three questions (not 11): 1. One of the dimensions discussed in M-Theory (or perhaps pre-M-Theory String Theory?) is where every possible action that can take place, 'does' take place but in different dimensions. I think I have that right. Does this theory have a name? 2. Yet another dimension suggested or predicted in M-Theory relates to strings on different Branes... is this correct? 3. Also M-Theory predicts that instead of 10 dimensions that strings vibrate into, there are 11. Is it ever suggested that either of the dimensions in questions 1 and 2 are part of this 11 dimensions or, are we now looking at 13 dimensions (or more?)? As you can see, there are 3 primary questions however, curled up within each one are tiny additional higher dimensional questions. Rusty
ajb Posted October 24, 2009 Posted October 24, 2009 M-theory (what ever that is) is believed to be a completion of the 5 string theories. It is 11 dimensional as you say. The low energy dynamics is described by an 11d supergravity theory interacting with 2 and 5 dimensional branes. The string theories are understood as limiting or specific cases of M-theory. I do not really follow your questions. Merged post follows: Consecutive posts mergedI recommend Szabo's BUSSTEPP Lectures on string theory. arXiv:hep-th/0207142 for a good introduction to the subject.

I think 'intros' are the problem and why I'm asking questions which make no sense, lol. I need to graduate to intermediate level. Rusty
