To explain those rules, I'll need to talk about some basic atomic physics. Hydrogen-1's nucleus consists of only a single proton.Protons and neutrons together are called nucleons, meaning particles that can appear in the atomic nucleus.The problem, says Bronk Ramsey, is that tree rings provide a direct record that only goes as far back as about 14,000 years.
The technique hinges on carbon-14, a radioactive isotope of the element that, unlike other more stable forms of carbon, decays away at a steady rate.
The recalibrated clock won’t force archaeologists to abandon old measurements wholesale, says Bronk Ramsey, but it could help to narrow the window of key events in human history.
