Dark Energy

One of the noteworthy features of Hubble’s law is that, with the exception of the static universe with which Einstein and de Sitter began in 1917, it is the only redshift distance law that is isotropic and homogeneous (i.e., looks the same) for every galaxy in the universe. It is this feature that gives rise to attempts to explain it by means of a balloon with marks on it being infl ated, where, from the perspective of any mark, all the other marks appear to be receding. Th e marks on the balloon represent galaxies in the expanding universe.
