If you were the boss of a group of intergalactic explorers, what would you use as the "North" on the space compasses? (lemmy.ml)

On Earth, the cardinal directions are straightforward. The arrow on a compass points to the nearest magnetic pole. You can then use it to travel anywhere on Earth.

In space, the idea of anything being "central" enough to be used as a "North" (since the universe has no center) or being fixated enough to not somehow pose issues is more convoluted.

If you were a pioneer of space exploration, what would your "North" be?

Works very well until you're moving between superclusters, at which point the universe becomes homogeneous (as far as is known). At that point you probably just need to set an arbitrary origin for your system of coordinates.
