These are stars close enough that we can triangulate, using Parallax, to determine their absolute distance. This is just geometry, trigonometry. We then use our 100 year understanding of connection between the temperature, the spectra and sizes of these stars to give us the Main Star Sequence. Within this are the variable stars. There are several kinds but well understood because most exist within Parallax distances. These are stars that are known Candles or Light Bulbs, their spectra stands out easily identified. Wherever we find the signature pulsating signals we can know the output of these Candles. And then distance can be easily computed. Distances well over 100,000 light-years distance are easily seen today. Two orders of magnitude over 9000 years. Hubble Telescope gives us views of distance Galaxies with these unique Candles that reach million of light years. I can't accept the literal interpretation of the Bible, certainly about the beginning of existence for the earth and space.
does our ever changing position in space relative to the objects in question get accounted for in the calculations? how does the Doppler effect come in to play? over those great distances and great amounts of time, how does our own speed relative to that observed light affect time dilation? if you have a good link that would be great, save you some typing
