One of the earliest documented attempts to apply brane cosmology as part of a conceptual theory is dated to 1983. [ 5 ] The authors discussed the possibility that the Universe has ( 3 + N ) + 1 {\displaystyle (3+N)+1} dimensions, but ordinary particles are confined in a potential well which is narrow along N {\displaystyle N} spatial directions ...
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]
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").
Since the -form gauge fields naturally couple to extended objects with dimensional world-volume, Type IIA string theory naturally incorporates various extended objects like D0, D2, D4 and D6 branes (using Hodge duality) among the D-branes (which are charged) and F1 string and NS5 brane among other objects.
The inflationary multiverse is composed of various pockets in which inflation fields collapse and form new universes. Animation showing the multiple brane universes in the bulk Brane The brane multiverse version postulates that our entire universe exists on a membrane which floats in a higher dimension or "bulk". In this bulk, there are other ...

In string theory and related theories in physics, a brane is a physical object that generalizes the notion of a point particle to higher dimensions. For example, a point particle can be viewed as a brane of dimension zero, while a string can be viewed as a brane of dimension one. It is also possible to consider higher-dimensional branes.
In string theory, the NS5-brane is a fundamental extended object in six-dimensional spacetime that carries magnetic charge under the Neveu–Schwarz B-field.The tension of the NS5-brane is inversely proportional to the Newton gravitational constant, making it a solitonic object of the theory.
