It seems to me that an appropriate (linear(?) because the distances
are big) transformation T: R^3-R^3 could be used to calculate the new
star positions at any location, but how could one utilize such a
device to find one's way back to Earth?

(And besides, since you're giving yourself infinite time and the stars
move, it's not going to be a linear transformation.)

Um, what about if we want to calculate the path and assume instantaneous
travel instead?

Then by relativistic effects you'd arrive infinitely in the future long
after good old Sol went supernova and long after the big bang universe
came to it's big crunch, heat death or big rip end, looking for a space
traveling society, which if they didn't self destruct within decades of
your departure, would have much improbability surviving the universal end.

The suggestion to the use the "Hitchhikers' Guide to the Universe" may be
helpful, especially the improbability drive which might let you break the
speed limit. As I recall somebody built a hotel at the end of time for
time traveling tourists to view a very unique event.

Hilbert?


No matter how you travel from distance random location, you'll
need time travel to adjust your travels back to the home you know.
