According to Wikipedia, if the metric was vacuum, spherically symmetric and static the Schwarzschild metric may be written in the form: ds^2=((1-2GM/(c^2r))^-1)*dr^2+r^2*(dtheta^2+sin(theta)^2*dphi^2)-c^2*(1-2GM/(c^2r))*dt^2 I need someone to help me to derive an expression from the Schwarzschild metric that is a function of r that can be graphed, that clearly shows the singularity at r=0. Actually, their is apparently a pair of pos and neg singularities there. Is that true? Is that because there is a square root taken during it's derivation? Thanks.
