C14 ratios are decay related... but seeing as how we are looking at very long half life (~5730 years), and the fact that the Earth's orbit is elliptical over a year's time, any changes in decay rate would tend to average out.
I think I can understand that about the earth’s orbit.
Pretend we found a log on Mars; another on a moon of Saturn and another on . . . oh, in honor of the movie . . . one of the moons of Endor.
Is it now conceivable, or not, that the decay rates could be different for each location?
