Radioactive dating: Modern nuclear bomb tests have created an extra high level of ¹⁴C in our atmosphere. Suppose that future archaeologists date samples from our era, but do not know about this testing. Will their dates be too young, too old, or still correct? If correct they are correct, why?

Question

Future archaeologists, not knowing about the bomb tests, would interpret this as indicating a more recent origin than is accurate, thus making their dates too young.
