Gravimetrics
From Memory Alpha, the free Star Trek reference
In physics, gravimetrics is the science concerning the measurements of gravity (or mass). In particular, it focuses on variations in gravity fields and the graviton subatomic particle.
In 2293, the USS Enterprise-B encountered severe gravimetric distortions from the Nexus. (Star Trek Generations)
In 2371, Captain Kathryn Janeway noted that the gravimetric flux density was over 2,000% when the USS Voyager encountered a type 4 quantum singularity. (VOY: "Parallax")
[edit] Background
Gravimetrics is currently not an official branch of science. Neither is the word "gravimetrics" used as frequently in real life as it is in Star Trek. It is currently an example of technobabble, though it remains to be seen if a physical "theory of everything" (such as a quantum theory of gravity) will change this in the real world.
