Those who propose an old universe assert there is a [[starlight problem]] for the [[young universe|young earth creationism]] model. Two key assumptions for the objection to a young universe model is that the speed of light has been constant and [[methodological naturalism]].
−
Because velocity = distance/time, a young earth creationist wishing to postulate a universe of approximately 6000 years old faces a number of problems if one uses assumes the [[speed of light]] has always been the same as it is now and/or insists on utilizing an [[a priori]] [[methodological naturalism]] approach to the issue:
−
−
1. If they accept that the [[speed of light]] is indeed a constant 299,792,458 meters per second (approximately 186,282.3 miles per second), then they must argue for massive and systemic error in the measurement of distance between Earth and the vast majority of the observable universe.
−
−
2. If they accept that the measured distances are correct, then they must argue for a catastrophic miscalculation of the speed of light.
