Age of the Universe

Classical Mechanics Level pending

The graph below shows the distance and recessional velocity of a number of distant galaxies. Assuming the universe started with a "Big Bang" in which all of these galaxies were crammed into a small area of space, and that they have all been moving apart at a constant speed since then, estimate the age of the universe in years.

Note: 1 megaparsec is \(\num{3.09e22}\) years.
