Had a thought earlier on long distance travel shortcuts through space in the probably nearer future than we think.
You have a Ship at point A, out past Pluto or further, for safety's sake. You want to get to Alpha Centauri, point B. Lets say that with an as yet undeveloped technology you open a large enough black hole to significantly bend a large amount of space.
In theory, if you could gain enough speed, the closer you got to light speed, the closer you could skirt the event horizon.
Now for someone who knows the math, viewing space on the interconnected quantum membrane, would this "pull in" enough space to significantly lower the distance traveled to point B, using the slingshot of the gravity to guide you around the curve?
