Radioactive dating problems

Two distinct sediment layers have formed in the lake every summer and winter over tens of thousands of years.

The researchers collected roughly 70-metre core samples from the lake and painstakingly counted the layers to come up with a direct record stretching back 52,000 years.

Scientists use a technique called radiometric dating to estimate the ages of rocks, fossils, and the earth.

Many people have been led to believe that radiometric dating methods have proved the earth to be billions of years old.

The technique hinges on carbon-14, a radioactive isotope of the element that, unlike other more stable forms of carbon, decays away at a steady rate.

Organisms capture a certain amount of carbon-14 from the atmosphere when they are alive.

Protons and neutrons make up the center (nucleus) of the atom, and electrons form shells around the nucleus.

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.

This has caused many in the church to reevaluate the biblical creation account, specifically the meaning of the word “day” in Genesis 1.

With our focus on one particular form of radiometric dating—carbon dating—we will see that carbon dating strongly supports a young earth.

“If you have a better estimate of when the last Neanderthals lived to compare to climate records in Greenland or elsewhere, then you’ll have a better idea of whether the extinction was climate driven or competition with modern humans,” says Paula Reimer, a geochronologist at Queen’s University in Belfast, UK.

She will lead efforts to combine the Lake Suigetsu measurements with marine and cave records to come up with a new standard for carbon dating.
