  2. Compactification (physics) - Wikipedia

    en.wikipedia.org/wiki/Compactification_(physics)

    A flux compactification is a particular way to deal with additional dimensions required by string theory.. It assumes that the shape of the internal manifold is a Calabi–Yau manifold or generalized Calabi–Yau manifold which is equipped with non-zero values of fluxes, i.e. differential forms, that generalize the concept of an electromagnetic field (see p-form electrodynamics).

  3. Kaluza–Klein theory - Wikipedia

    en.wikipedia.org/wiki/Kaluza–Klein_theory

    The technique of introducing compact dimensions to obtain a higher-dimensional manifold is referred to as compactification. Compactification does not produce group actions on chiral fermions except in very specific cases: the dimension of the total space must be 2 mod 8, and the G-index of the Dirac operator of the compact space must be nonzero ...

  4. Large extra dimensions - Wikipedia

    en.wikipedia.org/wiki/Large_extra_dimensions

    For larger numbers of dimensions, fixing the Planck scale at 1 TeV, the size of the extra-dimensions become smaller and as small as 1 femtometer for six extra dimensions. By reducing the fundamental scale to the weak scale, the fundamental theory of quantum gravity , such as string theory , might be accessible at colliders such as the Tevatron ...

  5. Brane cosmology - Wikipedia

    en.wikipedia.org/wiki/Brane_cosmology

    The central idea is that the visible, four-dimensional spacetime is restricted to a brane inside a higher-dimensional space, called the "bulk" (also known as "hyperspace"). If the additional dimensions are compact, then the observed universe contains the extra dimension, and then no reference to the bulk is appropriate. In the bulk model, at ...

  6. Five-dimensional space - Wikipedia

    en.wikipedia.org/wiki/Five-dimensional_space

    A five-dimensional space is a space with five dimensions. In mathematics , a sequence of N numbers can represent a location in an N -dimensional space . If interpreted physically, that is one more than the usual three spatial dimensions and the fourth dimension of time used in relativistic physics .

  7. Randall–Sundrum model - Wikipedia

    en.wikipedia.org/wiki/Randall–Sundrum_model

    In physics, Randall–Sundrum models (also called 5-dimensional warped geometry theory) are models that describe the world in terms of a warped-geometry higher-dimensional universe, or more concretely as a 5-dimensional anti-de Sitter space where the elementary particles (except the graviton) are localized on a (3 + 1)-dimensional brane or branes.

  9. Spacetime - Wikipedia

    en.wikipedia.org/wiki/Spacetime

    In physics, spacetime, also called the space-time continuum, is a mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum. Spacetime diagrams are useful in visualizing and understanding relativistic effects, such as how different observers perceive where and when events ...
