Interstellar travel using relative gravity canister (using black and white holes) to create gravitational wave tunnels so that canister may Enter the new time/space area and travel safely faster to near C and back down again safely.

Basically you send out gravitational waves, which have been compensated so that they do no oscillate but remain a constant variable within a range of acceptable outputs and condense time as many times as the canister can output to compensate for the magnitudes of powers of gravity/distance shortened cubed and then reverse output to lengthen time allowing it to slow to nearly a stop or some relative speed need for entry into star system.

Basically the acceleration function is an upside down parabola:

Starting at (-5,0) the starting location and increasing acceleration of the ship at time/space compressesion, up until the y intercept. (0,6) the point where it’s reached its maximum safe and expected compression rate (compresses to a single point when viewed from the outside) and/or the mid point of travel and begins to slow down at an increasing rate until it reaches it destination of (5,0) where it can rejoin normal gravity for that area, the gravitational waves can be directed to their decay path for safe disposal, and the trip is over in relative moments while still “traveling” in normal gravity.

Since every time you enter a gravitation wave tunnel it (I think) condenses space/ time either to the power of the gravitational constant/some distance, or the sum of the powers of condensing times the number of times it’s been condensed which is much greater. So you’d need a white hole excitement field to be able to produce enough electron to withstand the forces.

Something to think about is that each time you send out gravitational wave tunnel it’ll decay so travel will need to be guided to not interfere with excitable atoms/planets, plus you’ll leave a trail.
