I'm looking at Carroll's lecture notes 1997, intro to GR.(adsbygoogle = window.adsbygoogle || []).push({});

Equation 7.27 which is that hes argued the S metric up to the form ##ds^{2}=-(1+\frac{\mu}{r})dt^{2}+(1+\frac{\mu}{r})^{-1}dr^{2}+r^{2}d\Omega^{2}##

And argues that we expect to recover the weak limit as ##r \to \infty##.

So he then has ##g_{00}(r\to\infty)=-(1+\frac{\mu}{r}) ## [1]

where ##g_{00}=-(1+2\phi)## and equates these.

The reasoning is fine to me, but I dont understand the limit given by [1], surely as ##r\to\infty## ##g_{00} \to -1##

Thanks in advance.
