Are the Distances Real?


The question that is asked by those who have taken this position is "How accurate can the measurements of the distances be? The distances can not be measured directly." The flaw in this argument is that the methods used are based on very reasonable assumptions.


Parallax


Sizes and angles are exaggerated.

 Parallax is the angular difference in the apparent location of a celestial body as measured  from two points on the earth's orbit. This can be use in measuring interstellar distances, by use of basic trigonometry. The same basic concept is used in surveying.  Parallax is reliable only out to about 100 Light-year. Now this range has been marginally increased by Hubble Space Telescope, and long range probes could some day greatly increase the range. Parallax is an very accurate method for measuring stellar distances sense it is based on well established trigonometric principles.


Spectroscopic parallax

Spectroscopic parallax uses the comparison of apparent and absolute magnitude. Absolute magnitude is determined by the stars spectrum. While not really a parallax, this method is testable on stars measured at less than 100 light-years by a real parallax.


Cepheids

Cepheids are very luminous variable giant stars, that have an observed period and luminosity relationship that has been determined by cepheids measured at less than 100 light-years by their parallax. Sense this allows the absolute brightness to be determined, they can be used to measure distances, out to about 20 million Light-years.


Red shift

Red shift uses the relationship between the distance and apparent doppler shift revealed in galaxies by using cepheids to determine the distances of near by galaxies and it works for billions of Light-years.


The assumption involved in these measurements are reasonable and testable enough that we can be certain that the distances are accurate at least to with a factor of 10, leaving no room for the billion plus error need to squeeze the universe into a few thousand  Light Years.

This is not a good solution to the distant star light problem and it is not held by any Creation Scientists that I know of. It is definitely not held by any Creationist Astronomers.
