| Can you actually apprehend the idea of 11 dimensions? |

Well, there's a nice article in New Scientist's May this year edition that gives a brief introduction to some of them, but I can't find it at the moment :( here's a link to the article, if you're subscribed. http://www.newscientist.com/channel/fundamentals/mg19826542.300-four- radical-routes-to-a-theory-of-everything.html remove the space, ofc - stupid LW. |

String theory's got some major competitors gathering speed now. Personally, I'm not too fond of string theory. Can't place my finger on it, but something doesn't quite fit.
What are the competitors? I like looking up things I have little hope of understanding =p |

Eh.... I believe one of the string theories calls for 26 dimensions. I was under the impression, however, that M-theory focused on 10 spacial and 1 temporal dimension(s). 
My mistake. Bosonic string theory (only explains forces) calls for twenty-six. Since then, the theories (Type I, II, II-A and -B, H-O and H-A) that make up M-theory only require ten space dimensions and one of time. Bosonic theory is unstable, so it's at best a rough approximation. Thanks for catching that. |

| Wow, I actually think I understand most of it. It looked so complicated at first, but when you think about it, it starts to make sense. |

| I was under the impression the 11th dimension of M theory was the membrane one, Infinite 'branes' each with there own universe, including that universes own 10 dimensions on it |

I thought M theory was the leading string theory at the moment, and it kind of joined the 5 other versions of it. 
Yes, and no. M-theory sort-of joins them all together, but only in the sense that the main principles of the five are the same. The details [shape of the strings, type of Calabi-Yao shapes, etc] are altered a little bit. |

| Hm, that was interesting. I don't think I understood all of it, but then that's what college is for. |

This may hurt your head a little http://www.youtube.com/v/XjsgoXvnStY&hl I followed it, just about I thought string theory called for an 11th dimension though..anyone know anything about that, please tell me 
String theory actually calls for twenty-six dimensions of space. Out of that twenty-six, all but three are curled up so tightly that we can not notice them, unless we are able to probe at that small of a level.

26?! Have you got any links? Wiki says 11 only I think How many do they want? XD 
As many as it takes to make the theory work, I suppose. |
