摘要: The Bianchi I metric describes a homogeneous, but anisotropic universe and is commonly used to fit cosmological data. A the angular distribution of 740 supernovae type Ia with measured redshift apparent luminosity presented. It contains an intriguing, yet non-significant signal preferred direction in sky. Large Synoptic Survey Telescope being built Chile should measure some 500 000 within next 20 years verify or falsify this signal.
