If radiocarbon lasts only a few hundred thousand years, why is it found in all the earth’s diamonds dated at billions of years old?
Organisms at the base of the food chain that photosynthesize – for example, plants and algae – use the carbon in Earth’s atmosphere.
They have the same ratio of carbon-14 to carbon-12 as the atmosphere, and this same ratio is then carried up the food chain all the way to apex predators, like sharks.
If carbon dating is a fact, then coal layers cannot be millions of years old, and the secular “geological time scale” breaks down.
Radiocarbon dating is one of the most widely used scientific dating methods in archaeology and environmental science.
Carbon-14 dating is a method, based on unprovable assumptions about the past, used to date things that contain carbon (e.g. It can only give maximum ages of around 50,000 years and yet C-14 has been found in fossils and diamonds thought to be millions and billions of years old respectively.
Scientists use a technique called radiometric dating to estimate the ages of rocks, fossils, and the earth.
is a technique used by scientists to learn the ages of biological specimens – for example, wooden archaeological artifacts or ancient human remains – from the distant past.
It can be used on objects as old as about 62,000 years.
Along with hydrogen, nitrogen, oxygen, phosphorus, and sulfur, carbon is a building block of biochemical molecules ranging from fats, proteins, and carbohydrates to active substances such as hormones.
