I don't remember if I made a past thread on this but this ~11 minute video is about a year old and explains the observations of frame dragging in a white dwarf star neutron star binary system and this frame dragging was one of the predictions of relativity thus this observed frame dragging adds yet more evidence for relativity that further vindicates relativity.

Don't know if you heard of Gravity Probe B which looked for and found pretty much what Relativity predicted.
It took over 30 years just to develop and perfect the technology of having spheres as perfect as could be made and then putting them in orbit and measuring the drift of spin.
