The technique of carbon-14 dating relies on the assumption that the cosmi-ray intensity has been constant for at least the last 50,000 years. Suppose it was discovered that the cosmic-ray intensity was much greater 10,000 years ago. How would this discovery the ages of samples that have already been dated?
