The Eleven Dimensions of Christmas! 1 and 2 and 3...

[rrw4rusty]

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.

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.

I recommend Szabo's BUSSTEPP Lectures on string theory. arXiv:hep-th/0207142 for a good introduction to the subject.

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