Calculating distance between two points in spacetime
Hi,
I have spacetime surrounding a black hole described by Scharzchild metric and I want to find the distance a stationary observer would measure between two stationary points separated by dr radially.
I thought I could use the expression for the line element (stationary), ds = (1-2GM/rc^2) c dt, and integrate from r->r+dr. However it is in terms of dt...so I must have gone wrong somewhere.
Thanks
