“Dragging Spacetime” –Predicted by Einstein’s General Theory of Relativity




“After ruling out a range of potential experimental errors, we started to suspect that the interaction between the white dwarf and neutron star was not as simple as had been assumed to date,” concluded Willem van Straten, an astronomer at the Auckland University of Technology, about the detection of Lense-Thirring precession. This relativistic effect first hypothesized a century ago alters the orbit of two compact massive objects in a binary star system. The results of the twenty-year study confirm a prediction of Einstein’s general theory of relativity. When a massive object rotates, general relativity predicts that it pulls the surrounding spacetime around with it, a phenomenon known as frame-dragging.
