Well, I usually like to consider myself the Lorenz Reference Point of the
universe, so it's anyone who's accelerating relative to me!
Seriously, I see what you're saying--to the person in the ship, the
"stationary observer" (which, by the way, I mistyped as "stationery
observer," who spends his time watching envelopes) appear to accelerate away
in the opposite direction. To which I say, let me think about it. I'm at
work now and have to leave in about a minute, but I know I have some
material on this subject at home. I'll post an actual reply a little later.
As a quick thought, I think the occupant of the ship, who is moving
relative to the inertial reference frame of the stationary observer, which
includes the space around the observer. Local space as a whole isn't moving
away with the traveler, so the time dilation occurs for the person leaving
the inertial reference frame.
More later,
Dave!
