Radiometric dating bill nye
Second, neither set of dates overlaps within uncertainty, as the sample age differs substantially from one lab to the other.Ages for the "other wood" samples differ by more than 8,000 years, meaning that Geochron measured more than twice the concentration of 14C in the same sample, compared to ANSTO's analysis.This curve removes the assumption in conventional radiocarbon dating that 14C was constant over time.Stalagmites provide another tool for gaging the history of atmospheric 14C, since these banded records are datable by the U-Th disequilibrium method or, in ideal cases, counting annual bands.
The YEC can argue, therefore, that prior to the flood, the relative abundance of 14C was much lower than today.By radiocarbon dating calcite along the growth axis of the stalagmite and comparing these ages to U-Th dates, geologists can test and refine the calibration curve (e.g. These highly corroborated, independent lines of evidence thoroughly disprove the YEC claim that atmospheric 14C increases significantly only after a recent, global flood.In summary, yes: Ken Ham undermines his own position by citing this study, though he does not mean to.In 1993, several samples of charred and petrified wood were collected during construction of a mining ventilation shaft in central Queensland.The wood samples were seemingly well preserved inside the lava flow that encased them. The 24-page publication is rather verbose, reading more like a drawn-out lab report than a scientific study, but it contains all the details necessary to assess the feasibility of Dr. Wait, if the fossil wood and basalt are both older than 6,000 years, doesn't Ken Ham undermine his own position by citing this study?
