View Full Version : Frame Dragging Confirmed

SUMMARY: When developing his General Theory of Relativity, Albert Einstein predicted that the Earth should drag space and time around with it as it rotates on its axis. NASA's Gravity Probe B spacecraft was launched earlier this year to help confirm this prediction, but an international team of researchers has beaten the spacecraft to a conclusion. By carefully tracking the position of the LAGEOS and LAGEOS 2 satellites - beachball-sized spheres covered in mirrors - they discovered that their orbit is being shifted by about two metres a year by this dragging effect by the Earth's gravity, almost exactly what was predicted by Einstein.

Would frame dragging affect other, more important satellites, e. g. communications satellites?
