the evidence does not suggest this - it is not merely an assumption.awstar said:Possible sources of error in determining distances of stars outside our galaxy.
1. the assumption that the universe is expanding from every point in the universe might be erroneous.
The temperature/luminosity properties of stars is a result of the nature of nuclear fusion in the core of the star, and results in the HR-Diagram. If you were correct then the HR diagram would appear to be different from theoretical predictions, and it is not. Furthermore the only way to change the temperature/luminosity properties would be to change the fundamental constants between the galaxies, and this would have additional remifications regarding such things as lamb shift and spectral profiles. all the measured properties of matter in other galaxies appears for all intents and purposes to be the same as the properties in the lab. Your suggestion ignores the remifications of differing properties.2. the assumption that ratio of size to luminosity of a star is consistent from galaxy to galaxy might be erroneous.
The speed of light is a derived property and not an assumption as such, since it is simply a function of the permittivity and permeability of free space. to change these parameters would again have significant ramifications in other areas of physics and would be easily observable. no observances of this erronous kind have been made.3. the assumptions made to allow for a constant speed of light through out the universe might be erroneous.
There is no dynamical reason to expect this, and the suggestion is nothing more than the appearance of age argument, which has been rejected by theologists as theologically disasterous. it makes God a liar.What if there is a finate age, and running the clock backwards as far as it goes backwards only goes only takes us back 6000 years. -- the moment of creation as recorded in the Bible? Then the universe couldn't be declared to be 15 billion years old, could it? The only reason the universe can be declared to be 15 billion years old is because the declarer ignores the possibility that it was created 6000 years ago and assumes it started in one spot. Hardly evidence that proves the theory of a young universe is false. It's more like declaring the theory of a young universe is false.
see above. the argument is not as simple as you suggest and would have massive effects on other physical properties. No deviations are observed.What if Stars in different galaxies don't have the same absolute size and luminosity relationship as stars in our galaxy? What if God has created different "kinds" of galaxies, just as He created diffent kinds of heavenly bodies.
see above.What if the assumptions that were made in place of those given up to allow for the theory of relativity resulted in unforseen errors in describing the universe. When a more accurate description of the nature of the universe is revealed by God, the speed of light through the universe might no longer be assumed constant. If the description of the nature of the universe became more accurate with Albert Einstein's imagination from how Newton imagined it, who's to say there isn't an even more accurate description of the nature of the universe. In fact, wouldn't it be a certainty that there is a more accurate description from what we know now?
