PSR J1141−6545 is notable because it has shown several relativistic theories to have real-world results. The star is emitting gravitational waves and the process of time dilation appears to be affecting the orbit of the white dwarf. In January 2020 it was announced that the stars were also showing the Lense-Thirring effect,[8] whereby a rotating mass drags the surrounding spacetime with it.[9]
