warp space and or time

Let's just use a nonrotating massive body since it's simpler than an Alcubierre metric.

 

Nonrotating spherical bodies have a Schwartzchild metric:

[math]c^2\tau^2=(1-\frac{r_s}{r})c^2dt^2-(1-\frac{r_s}{r})^{-1}dr^2-r^2(d\theta^2+\sin^{2}\theta{d}\phi^2)[/math]

 

Let's see how far you have to get to get a flat space. [math]r_2=2G\frac{M}{c^2}[/math], so:

[math]c^2\tau^2=(1-2G\frac{M}{{c^2}r})c^2dt^2-(1-2G\frac{M}{{c^2}r})^{-1}dr^2-r^2(d\theta^2+\sin^{2}\theta{d}\phi^2)[/math]

 

So, we want to get [math]{1-2G\frac{M}{{c^2}r}}=1[/math]. That's obviously not going to work since it needs an infinite radius. So, there's no distance away that will not be affected. The question is how little do you want it affected?

Some folk at NASA have attempted to create a 10mm warp bubble with a 1:10,000,000 space-time purturbance. (They were trying to get half of a split laser beam to hit an interferometer sooner than the other by reducing it path length by one micrometer via space warp.) Results of the experiment were inconclusive.
