Debates on scientific dating

Some people have excellent experiences with online dating that end in satisfying relationships.

Without a clear plan, online daters can get stuck endlessly "shopping" for the perfect partner, rather than actually starting a satisfying relationship.But even he “realized that there probably would be variation”, says Christopher Bronk Ramsey, a geochronologist at the University of Oxford, UK, who led the latest work, published today in Science.Various geologic, atmospheric and solar processes can influence atmospheric carbon-14 levels.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.“If you’re trying to look at archaeological sites at the order of 30,000 or 40,000 years ago, the ages may shift by only a few hundred years but that may be significant in putting them before or after changes in climate,” he says.
