The Schwarzschild radius RBH for an object of mass M is defined as RBH = 2GM c² where c is the speed of light and G is the universal gravitational constant. RBH gives the radius of the event horizon of a black hole with mass M. In other words, it gives the radius to which some amount of mass M would need to be compressed in order to form a black hole. RBH = The mass of the Sun is about 1.99 × 10³0 kg. What would be the radius of a black hole with this mass? m
