no goats for me...not since I discovered alpacas!

Little Hawk..that statement is durn close to something I can live with! It says very little that would seem to 'expect' others to make the same assumptions. It states the basics about your experience, and acknowleges that other explanations are indeed possible.

In fact, the most difficulty I have with it is understanding what "...a system that isn't defined in terms of speed, but rather in terms of present location" might mean as a practical matter. If you are able to wrap your head around that concept, great! I can't seem to grasp it, and that can either be MY problem, or a linguistic thing used to state something with no direct referent. (I simply do not know which)
It would be fun to sit around RT someday and explore this without the time delays and 'flatness' of all text.
