Astronomers have observed a small, massive object at the center of our Milky Way galaxy. A ring of material orbits this massive object; the ring has a diameter of about 15 light years and an orbital speed of about 200×10m/s3 Many astronomers believe that the massive object at the center of the Milky Way galaxy is a supermassive black hole. The Schwarzschild radius of such an object is the distance within which nothing, not even light, can escape its gravitational attraction. General relativity gives the Schwarzschild radius as RS=2GM/c2 is the gravitational constant, G and Mis the mass of the object, and C is the speed of light. What is the Schwarzschild radius of the object at the center of our galaxy?
