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, influences the space-time around it. As the object spins, it "drags" the surrounding space-time along with it, causing nearby objects to experience a slight change in their motion. This effect can be observed in the orbits of satellites around Earth. For instance, the Gravity Probe B satellite was launched to measure frame dragging near our planet. The results confirmed that Earth's rotation does indeed affect the space-time around it, demonstrating the intricate relationship between mass, motion, and gravity.
