I tried getting there but for some reason your limited in travel distance, still trying to figure out how to get there
zoom out.
next: zoom out again.
then: zoom out.
do you see the galaxy and their arms?
no?
then go back to the first line.
in short: jump from system to system along the arm.
also it does help to have the wormholekey. so you can jump into a blackhole and see where it gets you.
it got me from the middle of one arm allmost the whole way into the center.
tip: try not to **** off the grox, if they arn't allready.
if you just ignore them, they will do the same. (at least in my experience on 'easy'-mode)
not being attacked all the time you are near the center (its ALL grox territory) makes the journey much less stressfull. =)
