Calculate the escape velocity of an object leaving a black hole with mass equal to 20 times the Sun's mass at a distance equal to the Earth's orbit (r = 1.5x 10¹¹ m) away from the singularity (the location of the black hole's center). Express your answer as a fraction of the speed of light c. Even though black holes have all of their mass concentrated at a single point in spacetime (called the singularity), the size of a black hole is often described using a distance called the Schwarzschild radius. This distance, r, is the distance at which the escape velocity is equal to the speed of light, c. Once an object or a light beam gets closer to the black hole singularity than the Schwarzchild radius, it cannot escape, because nothing can travel faster than c. b.
