Anisotropic universes with isotropic cosmic microwave background radiation | W C Lim

1 Dec 1999 | Journal: | Class.Quant.Grav. 18 (2001) 5583-5590 | Subject: | gr-qc | Abstract: | We show the existence of spatially homogeneous but anisotropic cosmological models whose cosmic microwave background temperature is exactly isotropic at one instant of time but whose rate of expansion is highly anisotropic. The existence of these models shows that the observation of a highly isotropic cosmic microwave background temperature cannot alone be used to infer that the universe is close to a Friedmann-Lemaitre model. | Source: | arXiv, gr-qc/9912001 | Services: | Forum | Review | PDF | Favorites |
