Sound like "its gravity will cause the quasar's apparent position in the sky to shift by a distance that depends on the speed of gravity" would be a more fair statement.

I would posit that it's apparent position in the sky and its position in the sky are the same thing, since "in the sky" is only a particular reference frame based on a particular observation point - that of within earth's atmosphere.

Why do work when I can sit around picking at nits? ;)

Shalom.

You're quite right, of course, and I even realized that when I wrote what I wrote, but my position was (and is) that clarity is a higher value than absolute elimination of redundancy.

...as I further illustrated by using the phrase "absolute elimination..." 8-)
