Substitute this converted value for the hubble constant 73km/8xmpc x 1mpc/ 3.086x10^19km = 2.37 x 10^-18 1/s into the time equation, (t = 1/H0), to find the age of the universe in seconds. Now convert the time from seconds to years. This value is the approximate age of the universe. Write the age in scientific notation. Use the conversion, 1 year = 3.154 × 107 seconds.
