On the second piece of graph paper, plot these 21 galaxies. Label the axis and units. Note that Hubble's original work occupies a very small area as compared to this plot Draw a box on the graph showing the velocity and distance that were covered in the original work Then draw a line through the points on this graph and notice how a more linear relationship is defined. Calculate Hubble's Constant and determine the age of the universe: Hubble was Only woncing wlS 2.0 MPC Ho = slope = 560 km/sec/Mpc %3D %3D Age of Universe (1/H.) x (3.08 x 1019 km/Mpc) x (1 year/3.15 x 107 sec) = %3D %3D = (1/ km/sec/Mpc) x (3.08 x 10 km/Mpc) x (1/3.15 x 10' sec) = %3D yrs
