I have been recently reading a lot on Super Strings and M-Theory, and I discussed this with selfAdjoint earlier but he said I should advise to someone say, like(adsbygoogle = window.adsbygoogle || []).push({}); jeff, Doc Al, Integral, anyone with a very experienced knowledge of this on this matter of perplexed dimensional frustration.

In M-Theory which is trying to explain the theory of everything theorists speak about 11 dimensions, adding one because of string theory. But, what I don't understand is:

- How does M-theory work though?
- Why does everything work out perfectly when there are 11 dimensions instead of say, . . .8. Why 11, why not another number?

Conclusion:Specifically saying how do theorists determine 11? What is the math behind 11?

I know now that nonsupersymmetric bosonic string theory for solving gives you that D = 26 and then that supersymmetry "eats" 16, giving you a duality of five and somewhere adding one dimension, but that's in abstract laymen's terms, translating to how do this happen and somebody explain-speak.

Note: The above is only because of help from sA. Otherwise I wouldn't have a clue!

I have listened to selfAdjoint and I believe he was on the right path because it made sense but he said his study group waslimitedon increasing his already vast knowledge, so he said I should make this into a thread, so I did.

Now, I have been referring to this site: http://www.theory.caltech.edu/people/jhs/strings/str154.html to try to clear some confusion, but it isn't working, so I need your help! It explains a lot of concepts, but not the concept of 11.

I appreciate it if you can resolve this for me!

Thanks,

Jeebus
