Not what you're looking for?

Ask Custom Question

The Schwarzschild radius describes the critical value to which the radius of a massive body must be reduced for it to become a black hole.

R = 2 G M / c 2

where

G = gravitational constant 6.7x10 -11

M= mass of the object

C = speed of light 3x10 8

The sun has M = 2x10 30 . What is the Schwarzschild radius for the sun? [Note its true radius is 700,000.]
