warp space and or time

[silverghoul1]

what well be required to warp space and or time, and how much of an area would be affected by the "warping"

[Endy0816]

Can you explain a little about what you mean by warping?

or is it to much of fiction to do this

or maybe just enough power to create a blackhole

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?

lets give it a good 10 square feet.

 

Also thank you, i would never be able to do this for my life

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.
