Einstein’s theory of gravity, also referred to as General Relativity, predicts that a rotating body such as the Earth partially drags inertial frames along with its rotation. In a study recently published in EPJ Plus, a group of scientists based in Italy suggests a novel approach to measuring what is referred to as frame dragging. Angela Di Virgilio of the National Institute of Nuclear Physics, INFN, in Pisa, Italy, and her colleagues propose using the most sensitive type of inertial sensors, which incorporate ring lasers as gyroscopes, to measure the absolute rotation rate of the Earth.
