"Absolute Position"
This is a bit of a contrived scenario, but I wonder how it might be solved..
Say you have two highly advanced civilizations that want to meet each other, but in order to do so the trip will take billions of years.
Now, in this time, solar systems collapse, orbits change, etc, etc..
Since you have no idea whether a relative point in space will still be valid in the future, how would you communicate the rendezvous point?
(Nevermind how they communicated with each other in the first place)
