Branes in a sentence

It quickly became clear that D-branes and other p-branes, not just strings, formed the matter content of the string theories, and the physical interpretation of the strings and branes was revealed—they are a type of black hole.

In string theory, D-branes are an important class of branes that arise when one considers open strings.

Sen 1993 In spite of this progress, the relationship between strings and five-dimensional branes remained conjectural because theorists were unable to quantize the branes.

A feature of gravitons in string theory is that, as closed strings without endpoints, they would not be bound to branes and could move freely between them.

Although the physical phenomena described by M-theory are still poorly understood, physicists know that the theory describes two- and five-dimensional branes.

Andrew Strominger and Cumrun Vafa calculated the entropy of certain configurations of D-branes and found agreement with the semi-classical answer for extreme charged black holes.

Branes main In string theory and related theories such as supergravity theories, a brane is a physical object that generalizes the notion of a point particle to higher dimensions.

D-branes are dynamical extended objects of various dimensionalities predicted by string theory that could play this role.

In 1987, Eric Bergshoeff, Ergin Sezgin, and Paul Townsend showed that eleven-dimensional supergravity includes two-dimensional branes.

In 1990, Andrew Strominger published a similar result which suggested that strongly interacting strings in ten dimensions might have an equivalent description in terms of weakly interacting five-dimensional branes.

In dimension p, these are called p-branes.

In other words, a system of strongly interacting D-branes in string theory is indistinguishable from a black hole.

In the late 1980s, it was natural for theorists to attempt to formulate other extensions in which particles are replaced by two-dimensional supermembranes or by higher-dimensional objects called branes.

In this way, the conjectured relationship between strings and branes was reduced to a relationship between strings and strings, and the latter could be tested using already established theoretical techniques.

It is also possible to consider higher-dimensional branes.

Moore 2005, p. 214 Branes are dynamical objects which can propagate through spacetime according to the rules of quantum mechanics.

Much of the current research in M-theory attempts to better understand the properties of these branes.

Some scenarios postulate that our Big Bang was created, along with our universe, by the collision of two branes.

String theorists attempt to construct a unified description of quantum mechanics and general relativity by building a theory based on small strings, and branes rather than particles.

String theory predicts 1- to 10-branes (a 1- brane being a string and a 10-brane being a 10-dimensional object) that prevent tears in the "fabric" of space using the uncertainty principle (E.
