You are describing the reason for a curve as an object moves PAST another it is attracted to. The object
bends toward the attractor, and depending upon the degree of attraction and speed of the object, either a
permanent orbit or what you term a gravity boost ensue. But just as your probes move in straight lines when
NOT passing a gravitational giant, a straight line you choose to call a hyperbolic orbit, just so exiting
comets in what you term a long period ellipse likewise are moving in an essentially straight line. The flaw
in your argument is that YOU ARE GIVING THE FORCE OF GRAVITY THE SAME STRENGTH NEAR
AND FAR!
Do your probes experience the came degree of curve when away from a planet they are passing as when
passing? They do NOT. Likewise, when the comet has LOST its curve as it is slowing down during its exit,
this is a clue that it will not REGAIN this curve as the distance increases. Look at the rate of loss! Project
THIS out into space and see where it gets you! It gets you a comet that completely comes to a stop, just
barely further along in the curve as when you last saw it!
