Einstein’s general theory of relativity, published in 1915, which explains gravity as a consequence of the curvature of space-time created by the presence of mass and energy, has never before been proved in the existence of a star orbiting a supermassive black hole.
But scientists can now confirm that the orbit of the star, called S2, is shaped like a rosette, which is supported by the physicist general theory of relativity.
There an s and a ‘ missing there. Could be ‘s and could be s’, dependent upon whether we want to say the theory of the specific Einstein, or of all the profession. But must do better, report later for your beating.
