Radiocarbon Calibration Is Stretchy

August 20, 2020 | David F. Coppedge

The latest calibration curve for radiocarbon dating is raising eyebrows. Will it upset what is “known” about the past?

Sometimes “new and improved” is welcome news. For example, the Hubble Space Telescope improved the resolution of faint objects compared to ground-based telescopes tremendously. Without controversy, it has dazzled the world with the beauty of astronomical objects. Other times, though, “new and improved” suggests that what came before was bad. And sometimes one doesn’t want a “new and improved” version of something, like the standard kilogram or meter, because it throws off trusted measurements made prior to the change. Well, now we have a new calibration curve for radiocarbon dating, also called carbon-14 dating. What might be the reaction of scientists and observers to this change?

From a second article referenced by the first article:

Bard, Heaton et al., “Extended dilation of the radiocarbon time scale between 40,000 and 48,000 y BP and the overlap between Neanderthals and Homo sapiens.” PNAS first published August 17, 2020 https://doi.org/10.1073/pnas.2012307117.

Comparison between radiocarbon ages (Upper) and corresponding calibrated ages with IntCal13 (Middle) and IntCal20 (Lower) for a selection of human bone samples of Neanderthals (red) and early H. sapiens (blue). The 14C ages (±1σ) were calibrated using IntCal13 (ref. 2, Middle) and IntCal20 (ref. 1, Lower) in OxCal 4.2 (16). Note that the time axes of the three panels have exactly the same duration (13,000 y). The oblique dashed lines highlight the time dilation effect centered around 43 ka BP. Dataset S1 provides data and sources.

Interesting....
Since Noah’s flood was around 2350 BC, it would indicate that there are still some variables that they haven’t accounted for.

Just sayin’
