cperkinson Posted June 17, 2009 Posted June 17, 2009 What is this string theory dealing with 11 demensions by Einstein all about? Any ideas on where I should start looking online? Merged post follows: Consecutive posts mergedWow very complex. Can anyone give me a small basic description?
ajb Posted June 17, 2009 Posted June 17, 2009 You want to know why string theory says 26 or 10 dimensions? Basically, a classical non-interacting string theory can be formulated in any dimensions. The problem comes when one tries to quantise this theory. It turns out that such a quantum theory can only be consistent in 26 dimensions for a bosonic string and 10 for a supersymmetric string. The original interest in 11d comes from the fact that certian string theories are low energy limits of (the unique) 11d supergravity. This then to understand the high energy theory M-theory is proposed.
