Frame dragging is a phenomenon predicted by Albert Einstein's theory of general relativity. It occurs when a massive rotating object, like a black hole or a neutron star, drags the surrounding spacetime along with it. This effect can influence the motion of nearby objects and light, causing them to follow curved paths. The most notable example of frame dragging is observed around Earth, where its rotation slightly affects the orbits of satellites. This effect, although small, has been measured by experiments such as the Gravity Probe B mission, confirming Einstein's predictions about the behavior of spacetime around rotating masses.
