How can you measure distances with trigonometry when you don't have straight lines and you can't be certain of just how curved the sides of the triangle are?
If there were a curvature of spacetime it would affect the displacement of the star against the background not the lines we use to intercept the stars
apparent position and,therefore,the trigonometry would still be applicable and valid.

In the beginning the Universe was created. This has made a lot of people very angry and been widely regarded as a bad move.
