Many theories of Albert Einstein's general and special relativity have been confirmed, but some remain under investigation for their accuracy
One of the theories for which the proof was sought was that concerning the movement of stars when they are under the gravitational effect of giant black holes. An international team of scientists argues that Einstein's theory is correct. At the heart of our galaxy is a huge black hole, Sagittarius A *. It is a black hole of an estimated diameter of about 45 million km and a mbad of about 4 million times the mbad of the sun. Near Sagittarius A * is a star, the S2. Two months ago, the star approached its orbit at its closest point to the black hole, and scientists had turned there the very powerful VLT telescope in Chile. The researchers saw the star approaching the black hole very closely to rapidly develop a very high speed phenomenon proposed by Einstein in the theory of general relativity
