Because gravitational waves from distant (billions of light years away) phenomena are incredibly faint, detecting them has been a daunting task. Decades of work have gone into the development of sufficiently sensitive detectors. In 2015, the [[LIGO]] detectors (one in Hanford, Washington and one in Livingston Louisiana) made the first detection of the waves.
