If Hubble's constant, H0, was measured to be 6.25 x 10-11 (years)-1, what would be the age of the universe?
Homework Answers
Age of universe = 1/H
H = Hubble constant
Age of universe = 1/6.25E-11/years
= 0.16E+11 years = 16E+9year
= 16 billion years

At extreme distances (over 1 billion light years) astronomers use hubbles law to determine how far away objects in our universe are away from us, a) How are spectral lines used to help determine these extreme distances b) Since Hubble's law relies on information from spectral lines, it can be said that spectral lines even help us estimate the age of the universe. How are spectral lines from galaxies at known distances used to determine hubbles constant, and how can...
