Gravimetric shear

Gravimetric shear, also known as "grav shear" or "spatial turbulence", is a type of gravimetric distortion and a shear force commonly associated with certain astronomical phenomena such as stellar clusters and neutronic storms, that can pose a threat to starships. Shear is caused by localized, extreme differences in the gravitational coefficient that produces great stress on matter that crosses the point of localized difference. Gravimetric shear might be characterized by a shearline.
 encountered severe grav shear in 2152 when it passed through a class five neutronic storm. ()
Protostar clusters, such as the Argolis Cluster, are generally regarded as impassible to spacecraft due to their intense gravimetric shear. In 2374, Captain Benjamin Sisko planned an attack on a Dominion sensor array through the Argolis Cluster. He was confident that Jadzia Dax, having studied protostar clusters, would be able to navigate the around the gravimetric shear. ()
In 2375, a Class 2 shuttlecraft from the was caught in the gravimetric shear from a proto-nebula, necessitating the evacuation of those aboard. ()
Later that year, Voyager experienced heavy gravimetric shear from a subspace sinkhole that had earlier swallowed one of its shuttlecraft. ()
In 2381, the Yosemite, a Type 6A shuttlecraft from the , was caught in a gravimetric shear caused by a gravity well, resulting in a crash landing on a desert planet. The shuttlecraft was abandoned and never salvaged, instead being replaced with the Yosemite II. ()
