Sep 18 at 14:45	comment	added	Agatha Harkness		i agree about dr but $$d\upsilon$$ needs to be positive if we're looking at the future, doesn't it?
Sep 18 at 14:43	comment	added	Dale		You are assuming that $dv$ and $dr$ have the same sign. Also it is $dv^2$, not $d^2v$. Same with $\theta$ and $\phi$
Sep 18 at 14:31	comment	added	Agatha Harkness		cause $$d\tau^2 = (1-\frac{2M}{r})d^2\upsilon -2d\upsilon dr -r^2 (d^2 \theta + sin^2 \theta d^2 \phi)$$ which basically only adds negative factors for r<2M
Sep 18 at 14:14	comment	added	Dale		With the sign convention you are using you will have negative $ds^2$ for spacelike lines, not for timelike worldlines. Why do you think otherwise?
