De Sitter Special Relativity: Effects on Cosmology
نویسنده
چکیده
The main consequences of de Sitter Special Relativity to the Standard Model of Physical Cosmology are examined. The cosmological constant Λ appears, in this theory, as a manifestation of the proper conformal current, which must be added to the usual energy–momentum density. As that conformal current itself vanishes in absence of sources, Λ is ultimately dependent on the matter content, and can in principle be calculated. A present–day value very close to that given by the crossed supernova/BBR data is obtained through simple and reasonable approximations. Also a primeval inflation of polynomial type is found, and the usual notion of comoving observer is slightly modified. PACS numbers: 03.30.+p; 04.20.Cv; 98.80.-k;98.80.Es

De Sitter Special Relativity
A special relativity based on the de Sitter group is introduced. Like ordinary special relativity, it retains the quotient character of spacetime, and consequently a notion of homogeneity. This means that the underlying spacetime will be a de Sitter spacetime, the quotient space between de Sitter and the Lorentz groups. Since the local symmetry will also be given by the de Sitter group, each ta...

Gravitational waves are the last unconfirmed prediction of the general relativity. These waves are tiny fluctuations in world frame that dessipate energy throghout space. The gravitatinal waves spectra of fluctuations can be originated from the non-linear effects during different cosmic evolution periods, especially from initially non-linear and excited vacuum state in the very early universe. ...
متن کاملPhase Spaces of Doubly Special Relativity
We show that depending on the direction of deformation of κ-Poincaré algebra (time-like, space-like, or light-like) the associated phase spaces of single particle in Doubly Special Relativity theories have the energy-momentum spaces of the form of de Sitter, anti-de Sitter, and flat space, respectively.
متن کاملIs Physics Asking for a New Kinematics?
It is discussed whether some of the consistency problems of present–day physics could be solved by replacing special relativity, whose underlying kinematics is ruled by the Poincaré group, by de Sitter relativity, with underlying kinematics ruled by the de Sitter group. In contrast to ordinary special relativity, which seems to fail at the Planck scale, this new relativity is “universal” in the...
متن کامل2 00 3 Doubly Special Relativity and de Sitter space
In this paper we recall the construction of Doubly Special Relativity (DSR) as a theory with energy-momentum space being the four dimensional de Sitter space. Then the bases of the DSR theory can be understood as different coordinate systems on this space. We investigate the emerging geometrical picture of Doubly Special Relativity by presenting the basis independent features of DSR that includ...
