An important tool in archaeological research is radiocarbon dating
Collecting additional data from different geographical areas and taking a closer look at historical climate trends could help sharpen calibration techniques, especially in hotly debated regions.
For the time being, archaeologists covering history in the Levant are being advised to take their dates with a pinch of salt.
Radioactive decay can be used as a “clock” because it is unaffected by physical (e.g. For instance, the amount varies according to how many cosmic rays reach Earth.The discrepancy is due to significant fluctuations in the amount of carbon-14 in the atmosphere, and it could force scientists to rethink how they use ancient organic remains to measure the passing of time.A comparison of radiocarbon ages across the Northern Hemisphere suggests we might have been a little too hasty in assuming how the isotope – also known as radiocarbon – diffuses, potentially shaking up controversial conversations on the timing of events in history.Just a few decades of difference could help resolve an ongoing debate over the extent of Solomon’s biblical kingdom, making findings like these more than a minor quibble in a politically contested part of the world.“Our work indicates that it’s arguable their fundamental basis is faulty – they are using a calibration curve that is not accurate for this region,” says Manning.
