{wiki=M2-brane}
In string theory and related theories of high energy physics, an **M2-brane** is a type of membrane that is a fundamental object in the context of M-theory, an 11-dimensional extension of string theory. Specifically, M2-branes are two-dimensional surfaces (or "membranes") that can exist in an 11-dimensional spacetime.
