Fr.: modèle cosmiologique homogène mais anisotrope
A solution to Einstein's theory of → general relativity that is spatially homogeneous but allows for rotation and/or shear. See also → Bianchi cosmological model.
→ anisotropic; → homogeneous; → cosmological; → model.
Bianchi cosmological model
model-e keyhânšenâxti-ye Bianchi
Fr.: modèle cosmologique de Bianchi
A cosmological model based on the theory of → general relativity, which is homogeneous but → anisotropic. There are actually ten dinstinct Bianchi types, classified according to the particular kinds of symmetry they posses.
Luigi Bianchi (1856-1928), Italian mathematician; → cosmological; → model.
model-e keyhânšenâsik, ~ keyhânšenâxti
Fr.: modèle cosmologique
A mathematical description of the Universe, based on observation, which tries to explain its current aspect, and to describe its evolution during time.
→ cosmological; → model.
Milne cosmological model
model-e keyhânšenâxti-ye Milne (#)
Fr.: modèle cosmologique de Milne
