>>>On the other hand, if the spaceship shortens infinitely, then it probably never would reach the desination planet. Every time it seemed to be getting close, it would shorten and be just as far away as it always was. I'm assuming, of course, that it shortens from the front, but maybe it shortens from the back at the same time, in which case, I have no idea where it would be in relation to the planet at any given time (which time is dilating anyway).

>>Hah! I started sending almost the exact same message to you then got to think of it in the middle, then rejected it. I thought, maybe it IS getting infinitely short BUT it's an infinitely short "dot" with coordinates by the planet. i.e. an object, although approaching infinite shortness (let's say it's become the width of a hyphen) can still move through space. As the fore end appproaches the destn, even if contracting, it can't contract any further back than its aft end, otherwise that would become like "negative contraction". >-S

You set the timer for the engine to switch off at the required point?

Is that where it begins to disappear up its own peristaltic fundamentulum?
