Decades ago, Einstein recognized that his newly formulated general theory of relativity described a weird twist in the orbit of Mercury. Now, that same effect has been observed in a star’s orbit of the massive black hole at the center of our galaxy. The star, called S2, is a member of a celestial environment that surrounds the Milky Way’s central black hole. For decades, researchers have traced S2’s elliptical motion around the black hole. Now, researchers have concluded that the ellipse revolves over time, what’s known as Schwarzschild precession. This precession is the outcome of the warping of spacetime produced by massive objects, according to general relativity. The new research proves that Einstein’s theory checks out once again, even in the extreme gravitational environment around a supermassive black hole.
