Usually I use a principle I call 'subjectivism'.

This is based on a priciple, that all inertial observers are of equal 
rights.

That's why I place the observer in the center of the system in question 
and measure everything in respect to the observer (or the associated 
coordinate system).

This makes the observer stop and everything else move.


This scheme is strictly subjectivistic, because one observer can be 
placed at the zero spot, but not two (or more).

The space seen from there is then the past light cone of that particular 
observer and usually called 'universe' (though not universal).

That's why we have an infinite number of different universes.

This scheme is not correct, but matches the subjectivitic view, which we 
usually have upon the world around us.

Since the observer does not move at all (by definition), he (or she) 
cannot possibly move with c (or any other velocity).

Now the observer has a point, which is already known (the tip of his own 
nose) and he could measure everything else from there.

Other points are less easy to find, like e.g. 'the center of the 
universe', or much less easy to use (e.g. the sun).
