Tony: Most of them except the speed of light as constant too. Just sayin'. And, I am not straining for an objection. There are numerous objections to the method. However, my original point was NOT simply about radiometric dating, but merely to point out that this discovery could have some major reverberations throughout many different disciplines. > > What happens to CMBR research, or the search for other planets/stars?-That is a good point, but remember the difference in the speed of light in this article depends upon the quantum characteristics of the space-time it is passing through. Difference in speed is not due to a change in light itself.
