WebbThe standard candle distance ladder builds up in the way you would expect – starting with the nearest objects as calibrators, gradually building up to more and more distant objects to eventually determine H 0 H 0. Standard rulers, however, use a reverse distance ladder which does not directly measure H 0 H 0. WebbEven though we can only "go out" to about 163 million light years with the parallax method, if we apply the standard candle or red shift methods to objects within this range, we get the same result. This fitting-together-and-pointing-to-the-same-conclusion experience is fascinating for scientists, because getting the truth is so difficult in an uncertain world.
