Even before LIGO made its first observations, scientists were able to observe gravity waves. In fact, scientists were making direct observations of gravity waves for more than 50 years before LIGO was built.

TruthBeTold Spoiler
This one is 100% true...
LIGO made the first observations of *gravitational* waves -- ripples in spacetime created by the merging of black holes or other bodies with very high gravity.
A *gravity* wave is just an ordinary wave, like what people surf on. A gravity wave is created at least in part by gravity trying to pull a fluid down.
This TruthBeTold conflated the terms "gravity wave" and "gravitational wave".
