WebWhy does string theory says there are 11 dimensions? There are various different things which may be referred to a string theory. 11 dimensions is the number of dimensions needed in m-theory, the theory that the 5 different superstring theories are actually just limiting cases of a single theory. Superstring theories need 10 dimensions (9 ... WebEdward Witten has popularised the concept of a theory in 11 dimensions, called M-theory, involving membranes interpolating from the known symmetries of superstring theory. It may turn out that there exist membrane models or other non-membrane models in higher dimensions—which may become acceptable when we find new unknown symmetries of …
