Carbon dating controversy
The 18-year space race between the Soviet Union and United States yielded the first moon landing.
It took just short of ten years for the Ancient Greeks to build the Parthenon on the Acropolis of Athens. Charles Darwin spent just five weeks in the Galapagos, a voyage without which he would have never written .
Michelangelo spent only four years painting the ceiling of the Sistine Chapel in Vatican City. In little more than a day, the entire population of Pompeii was wiped out by a volcanic eruption of Vesuvius in 79 AD. Human life moves fast, and because the 20 to 50-year ballpark of radiocarbon dating doesn’t quite keep up with it, Pearson and collaborators are developing a new radiocarbon method to place floating chronologies in an exact point in time.
Her team includes UA bristlecone pine expert Matthew Salzer; radiocarbon experts Greg Hodgins, Tim Jull, Peter Brewer, Richard Cruz, and Todd Lange; dendrochronologists Tomasz Wazny and Peter Kuniholm; and archaeologist Steven Kuhn.
The first modern humans did not evolve in Africa until about 1.8 million years ago.
The time between then and now is just a single tick on the universe’s clock.
For decades, radiocarbon dating has been a way for scientists to get a rough picture of when once-living stuff lived.
The method has been revolutionary and remains one of the most commonly used dating methods to study the past, but according to Charlotte Pearson, it’s ready for a makeover.
Dinosaurs did not appear until 230 million years ago, and ruled the planet for 135 million years.But alas, pattern-matching in order to date when a tree was cut isn’t always possible.Sometimes a wood sample doesn’t have enough tree rings or rings with growth patterns that match an already dated sample.Douglass, with his knack for pattern-recognition, discovered that he could take younger wood with a known date, and then match its rings alongside the pattern of an older sample.In 1929, with a beam from Show Low, Arizona, Douglass was able to bridge the gap for the first time ever.
