The only clue to your location is showing that one of the stars in the void is Polaris.
Can you find your way to Earth?
No but I never claimed that I or anyone else could do that without suitable training, star charts and instruments.
And that is the point I've been trying to make all along. No one, Heiwa included, can do these things alone and without appropriate training and equipment.
So, as I said, butt out of threads you are totally ignorant about.
Not you specifically, but in general - can it be done? Is it possible?
If you are in an unknown location in a void and your only clue is the identification of 1 star, Polaris - can you work out your location? Lets imagine you have a star chart on hand as well (however that star chart is based on Earths location in the universe). Can it be done? Can you use the reference point of Polaris to work out the other stars and finally, Earth?
I could not do it, that's for sure.
It depends greatly on how far from the Solar System we were. With foreseeable technology, I don't see us getting to even light-years away.
I don't know the answer for certain but, as a thought experiment, suppose we were a few light-years from the solar system.
But in addition to that simple star chart, I'd want the distances to at least the nearer and the main stars included.
Polaris is some 433 light-years away from the Solar System and that might be used as a reference direction.
There are 10 stars in the 4 to 11 light year range from the Solar System and the angles between those should at least enable the direction of our own Sun, which would still be at least one of the brightest stars visible.
So one approach would be to head towards the Sun. The positions of Polaris and the other stars would allow the ecliptic plane to be positioned and even establish the
heliocentric-ecliptic coordinate system as in:
Finding your way home from should be no problem.
Within interplanetary space, which is as far as we are likely to visit for many decades at least that
heliocentric-ecliptic coordinate
system is well defined by the Sun and a few key stars.
But, I'm neither an astronomer nor a planner of interplanetary space systems so the above is just my opinion.
There is a series of FAA documents intended to give a background for those working in
Advanced Aerospace Medicine.
This one has a bit on interplanetary missions:
4.1.6 Interplanetary Travel (PDF) but not a great deal on astronavigation.
There is this paper on that topic:
