Hubblova konstanta
Hubblova konstanta
(cosmology) the ratio of the speed of recession of a galaxy (due to the expansion of the universe) to its distance from the observer; the Hubble constant is not actually a constant, but is regarded as measuring the expansion rate today [(kozmologija) razmerje med hitrostjo umika galaksije (zaradi razširjanja vesolja) in razdaljo med opazovalcem in galaksijo; Hubblejeva konstanta v resnici ni konstanta, ampak se šteje, da meri hitrost razširjanja danes.]
