Oh, but I am being sincere. Tell me, isn't parallax the ONLY method
that these star distances can be measured? There are variations on the
theme, as shown at this web link, but ultimately the method is based on
parallax, or, it depends on luminosities which are assumed from other
stars which have been "measured" again by... parallax. Correct or
incorrect?
