Time equals distance in astronomy. And the colour spectrum confirms distances that are too large for determining using paralax. Notwithstanding that the spacecraft Gaia has been mapping the stars in our own galaxy using paralax for the last 7 years. One billion and counting to date, which will confirm tbe accuracy of colour spectrum anaysis to ridiculously high levels.Freddy:
The issue you raised is age, not distance. Parallax is limited to nearby stars.Then it’s lucky that we have other methods of measurement to test the results. Parallax and the colour spectrum for example. Unless trigonometry is under review as well?
The distances to stars aren’t theoretical. They are factual measurements. Hence their ages are likewise factual measurements.
