Which environmental pressure do you believe changes nuclear decay rate?

I specifically said that the rate is well established, as usual you are arguing against what I did not say. What environmental events do is make the measurement of the materials very difficult. How much erosion takes place in 4 billion years? Can you answer that one?

Why did you stop answering Dr. Stochastic's questions after one? I believe the next question was:

How old do you believe the earth to be?

Again, we're not looking for extreme accuracy here, you've been given the rather fair parameter of +/- 4.5 billion years!
