LIGO should also provide new, rigorous tests of Einstein's general theory of relativity, and — working with other gravitational
wave detectors due to come online in the near future — pinpoint precisely where in the sky the waves are coming from.

Among the top - ranked large - scale space missions in that report, the third - and fourth - ranked projects — a gravitational
wave detector and an x-ray observatory — have already dropped off the map
due to funding constraints.
Two detections of gravitational
waves caused by collisions between supermassive black holes should be possible each year using space - based instruments such as the Evolved Laser Interferometer Space Antenna (eLISA)
detector that is
due to launch in 2034, the researchers said.
But its announcement was delayed
due to the time required to understand two other discoveries: a LIGO - Virgo three -
detector observation of gravitational
waves from another binary black hole merger on August 14, and the first - ever detection of a binary neutron star merger in light and gravitational
waves on August 17.
Sensitive
detectors can tell if the length of the arms varies by as little as 1/10, 000 the width of a proton
due to passing gravitational
waves.
