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".
