Gap space and the Gap drive as
inspired by the GAP SERIES of Steven Donaldson.
Here then ,the first of the books of the "Gap Series" by Stephen Donaldson that describes the future of interplanetary space adventure and the GAP drive a type of spaceship booster system that jumps between dimensions.
Theese strings are the SHAPEs of the spaceships that do the gap drive.
Theoretically you could build boosters on spaceships in the shapes of strings that define the future of our solar system orbital change from orbit to orbit and displace there ahead of the real event by USING the GAP that would be there.
