  The LIGO results are among the greatest experimental achievements of all
times. Time and again scientists have compared this feat to Galileo pointing
his telescope to the sky, offering instead an 'ear' to the cosmos. After the
remarkable landmark of detection, the physics community will soon turn into the
study of the properties of the sources, addressing fundamental questions in
astrophysics and cosmology. A combined numerical and analytic effort to tackle
the binary problem is of paramount importance in light of the nascent program
of multi-messenger astronomy. The century of gravitational wave science is in
the making, and many discoveries are yet to come in the advent of a new era of
'precision gravity'.
