Astronomers saw a star dancing around a black hole. And it proves Einstein’s theory was right

For the first time, astronomers have observed a star orbiting the supermassive black hole at the center of our Milky Way galaxy. And the star is dancing to the predicted tune of Albert Einstein’s general theory of relativity.The study published Thursday in the journal Astronomy & Astrophysics.Observations of the star were made by astronomers using the European Southern Observatory’s Very Large Telescope in Chile’s Atacama Desert. They saw that the star’s orbit is shaped like a rosette.Isaac Newton’s theory of gravity suggested the orbit would look like an ellipse, but it doesn’t. The rosette shape, however, holds up Einstein’s theory of relativity.“Einstein’s general relativity predicts that bound orbits of one object around another are not closed, as in Newtonian gravity, but precess forwards in the plane of motion,” said Reinhard Genzel, in a statement. He is the director at the Max Planck Institute for Extraterrestrial Physics in Garching, Germany.





“爱因斯坦的广义相对论预测:一个物体围绕另一个物体的束缚轨道不是封闭的,不像牛顿引力那样,而是在运动平面上向前进”:Reinhard Genzel在一份声明中说,而他是德国加兴马克斯·普朗克地外物理研究所的主任。
