Chapter 14: Problem 49
A Water Black Hole. A clump of matter does not need to be extraordinarily dense in order to have an escape velocity greater than the speed of light, as long as its mass is large enough. You can use the formula for the Schwarzschild radius \(R_{\mathrm{S}}\) to calculate the volume \(\frac{4}{3} \pi R_{\mathrm{s}}^{3}\) inside the event horizon of a black hole of mass \(M\) What does the mass of a black hole need to be in order for its mass divided by its volume to be equal to the density of water \(\left(1 \mathrm{g} / \mathrm{cm}^{3}\right) ?\)
