One way to measure the age of the Universe is to... Calculate the look-back time of the farthest away galaxies using Hubble's Law and the speed of light Divide one by Hubble's Constant, since Hubble's Constant has dimensions of 1 /time Measure the amount of heavy metals in the Universe and use models of stellar nucleosynthesis to extrapolate age Calculate the age of the oldest globular clusters in the Milky Way since they were some of the first objects to formTo make its 3D map of the universe, the Sloan Digital Sky Survey needs to find a galaxy's location in the sky and its distance. To get the distance, they measure a galaxy's redshift. Which method from the cosmic distance ladder must they be using to find the distances? Radar Parallax Variable Stars Tully- Fisher Relation Hubble's Law.
