rrw4rusty Posted October 24, 2009 Share 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 Link to comment Share on other sites More sharing options...
ajb Posted October 24, 2009 Share 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 Link to comment Share on other sites More sharing options...
