Propagating at the speed of light, it is considered the (*) curvature in space-time in general relativity.
Physical evidence of this phenomenon is searched for by TAMA300, Geo600, VIRGO, and LIGO. Einstein rings are created by lensing, or bending of the light, by it. Propagating at the speed of light, it is considered the (*) curvature in space-time in general relativity. This phenomenon was studied by Galileo at the Leaning Tower of Pisa and becomes exponentially high near black holes. For 10 points, name this attractive fundamental force, which on Earth causes objects to accelerate at 9.8 meters per second squared.
