Introduction to LIGO & Gravitational Waves
INTRODUCTION
Throughout
history, humans have mainly relied on different forms of light to
observe the universe. Today, we are on the edge of a new frontier in
astronomy: gravitational wave astronomy. Gravitational waves carry
information on the motions of objects in the universe.
Since the universe was transparent to gravity moments after the Big Bang and long before light,
gravitational
waves will allow us to observe further back into the history of the
universe than ever before. And since gravitational waves are not
absorbed or reflected by the matter in the rest of the universe, we will
be able to see them in the form in which they were created. Moreover,
we will effectively be able to “see through” objects between Earth and
the gravitational wave source.
