According to [[John Hartnett|J.Hartnett]] the Hubble constant is not truly constant but it has emerged that there is an inherent scale dependence to its value. Thus, its determination depends on method used and on the distances to the sources.<ref name="starlight"/> The Hubble law written in an invariant way that enables one to derive a four-dimensional transformation similar to the Lorentz transformation is part of [[Moshe Carmeli|M.Carmeli]]'s new theory of [[Cosmological special relativity]].<ref name="CSR"/>
