A point particle is a 0-brane, of dimension zero; a string, named after vibrating musical strings, is a 1-brane; a membrane, named after vibrating membranes such as drumheads, is a 2-brane. [2] The corresponding object of arbitrary dimension p is called a p-brane, a term coined by M. J. Duff et al. in 1988. [3]
Membrane Theory may refer to: M-theory, a theory in physics that unifies all of the consistent versions of superstring theory; Membrane theory of shells, describes the mechanical properties of shells; Membrane potential, a theory that explained the resting potential of nerve and muscle as a diffusion potential
A p-brane sweeps out a (p+1)-dimensional volume in spacetime called its worldvolume. Physicists often study fields analogous to the electromagnetic field which live on the worldvolume of a brane. [27] In string theory, D-branes are an important class of branes that arise when one considers open strings. As an open string propagates through ...
Some versions of brane cosmology, based on the large extra dimension idea, can explain the weakness of gravity relative to the other fundamental forces of nature, thus solving the hierarchy problem. In the brane picture, the electromagnetic , weak and strong nuclear force are localized on the brane, but gravity has no such constraint and ...
M-theory is a theory in physics that unifies all consistent versions of superstring theory. Edward Witten first conjectured the existence of such a theory at a string theory conference at the University of Southern California in 1995. Witten's announcement initiated a flurry of research activity known as the second superstring revolution. Prior ...
The model is a braneworld theory developed while trying to solve the hierarchy problem of the Standard Model.It involves a finite five-dimensional bulk that is extremely warped and contains two branes: the Planckbrane (where gravity is a relatively strong force; also called "Gravitybrane") and the Tevbrane (our home with the Standard Model particles; also called "Weakbrane").
Matrix theory is a particular way of formulating supermembrane theory. It is still in development. It is still in development. The diagonal entries of an infinite dimensional matrix can be thought of as different supermembranes (parts) connected by 1 dimensional strings.
In 1998–99 Merab Gogberashvili published on arXiv (and subsequently in peer-reviewed journals) a number of articles where he showed that if the Universe is considered as a thin shell (a mathematical synonym for "brane") expanding in 5-dimensional space then it is possible to obtain one scale for particle theory corresponding to the 5 ...
