Questions on carbon dating
Manning noted that "scholars working on the early Iron Age and Biblical chronology in Jordan and Israel are doing sophisticated projects with radiocarbon age analysis, which argue for very precise findings. But our work indicates that it's arguable their fundamental basis is faulty -- they are using a calibration curve that is not accurate for this region." Applying their results to previously published chronologies, the researchers show how even the relatively small offsets they observe can shift calendar dates by enough to alter ongoing archaeological, historical and paleoclimate debates.
"There has been much debate for several decades among scholars arguing for different chronologies sometimes only decades to a century apart -- each with major historical implications. may all be inaccurate since they are using the wrong radiocarbon information," Manning said.
As the reaction would proceed, the water would heat up and vaporize, thereby depriving the neutrons of the moderating influence of liquid water, and the reaction would slow down.
As the water vapor condensed and reformed, the reaction would pick up the pace again.
Radiocarbon dating is a key tool archaeologists use to determine the age of plants and objects made with organic material.This also made for rapid heating of the earth interior (cool to start with).Furthermore, there is evidence that the main radioactive elements were concentrated in a layer low in the mantle and came to the surface progressively after that.Interestingly, using these sorts of ratios, one piece of moon rock dated as being 8.2 billion years old, to the amazement of the dating laboratory involved.As far as stars are concerned, the Th/Nd ratio has been shown to be unchanged no matter what the age of the star is, which leads one to two conclusions.
On pages 186 and 187 he describes the discovery at Oklo in the West African Republic of Gabon, of the remnants of an ancient site where an accident of geology produced, for a while, the conditions suitable for a sustained chain reaction to take place - a sort of natural nuclear reactor.
