Using sophisticated analysis tools, you detemined that the rock that fell on the roof of your car gave an age of 16 billion years. You double checked your age numbers in the lab and got the same age again! Assuming you are using Potassium / Argon ratios to determine the age (half life is approx 1 billion years), answer the following:

(a) How many half life's of Potasium radioactive decay are needed to give this 15 billion year age?

(b) Knowing from other reliable techniques, you find out that the rock is only 1 billion years old, give an explanation for thsi 16 billion year age?
