How rapidly is the universe expanding?
Since Edwin Hubble first discovered in 1929 that galaxies are getting
farther apart over time, allowing scientists to trace the evolution of
the universe back to an initial Big Bang, astronomers have struggled to
measure the exact rate of this expansion. In particular, astronomers
want to determine a number called the Hubble parameter, a measurement of
how fast the cosmos is expanding as we speak. The Hubble parameter tells
us the age of the universe, so measuring it was a major goal for many
astronomers in the latter half of the 20th century.
