Could an extreme solar event have distorted ancient radiocarbon dates?
I've been thinking about a question that I don't see discussed very often in alternative-history circles.
We generally treat radiocarbon dating as if it were a straightforward clock: an organism dies, carbon-14 begins declining, and the remaining amount gives us an approximate age.
But the atmosphere's carbon-14 concentration hasn't been constant.
Carbon-14 is produced when cosmic rays interact with Earth's atmosphere, and solar activity influences the cosmic-ray environment reaching Earth. We also know of unusually large ancient radiocarbon spikes, such as the events associated with what are now called "Miyake events."
So here's the question:
What would happen to radiocarbon chronology if Earth experienced an extraordinarily powerful, possibly unprecedented solar/cosmic-ray event?
