WebAmerican Mathematical Society :: Homepage WebM-theory brought all of the string theories together. It did this by asserting that strings are really one-dimensional slices of a two-dimensional membrane vibrating in 11-dimensional spacetime . Vibrations of higher-dimensional objects (as in three-dimensional vibrating blob or sphere or even more possible dimensions) are certainly a part of M-theory, [5] but the …

Webdimension, the membrane of M-theory wrapped on this dimension can be identified with the fundamental string. In this sense the membrane appears to be the most fundamental object in M-theory, providing renewed justification for earlier attempts to treat it thus. Indeed it is presumably the origin of the letter “M” in “M-theory.” Web27 jan. 2024 · In this review I will summarize the major historical discoveries and theories that tackled the existence and structure of membranes and I will analyze how these …
