# LARES-2 satellite successfully measures frame-dragging effect around Earth

The LARES-2 satellite has precisely measured frame-dragging, a relativistic effect where Earth's rotation drags spacetime around it. This confirmation of a key prediction of general relativity deepens our understanding of gravity and spacetime dynamics. The result marks a major milestone in experimental physics and validates decades of theoretical work.

**Importance:** 4/5
