Suppose the Sun became a 1-solar-mass Schwarzschild black hole. What would be its Schwarzschild radius?

Question

Quizplus · Accepted Answer

The Schwarzschild radius is given by r_s = 2GM/c^2, where G is the gravitational constant, M is the mass of the object, and c is the speed of light. For a 1-solar-mass Schwarzschild black hole, r_s = 2(6.674 × 10^-11 N m^2 kg^-2)(1.991 × 10^30 kg)/(3 × 10^8 m/s)^2 = 2.95 × 10^3 m = 2.95 × 10^-8 au.
